Abstract:
The research deals with analyzing peculiarities of using active rectifiers in frequency controlled electric drives of underground mine hoists. There are developed MATLAB models aimed at comparing two types of control systems – hysteresis-based and the one with pulse-width modulation. The research aims to analyze power modes and parameters of active rectifiers, quality of voltage control, current and power of active rectifiers and to determine ways of improving power indices of electric equipment of hoists as well as provide power compatibility of electric equipment and underground mines’ grids. Main attention is paid to analyzing circuitry of control systems of active rectifiers, parameters of power transformers and reactor equipment at underground mines’ substations, frequency converters and synchronous slow-speed motors. There are also analyzed statistic data on power consumption at underground mines equipped with automated systems of commercial and technical power meters and specific consumption of power. The research results reveal advantages of the pulse-width modulation control system as compared with the hysteresis one by using such indices as speed-performance, quality of control, potential of controlling reactive power and the power factor. Application of the research results will enable determining structures and methods of adjusting control over the active rectifier in the frequency-controlled drive of underground mine hoists.

Abstract:
The Northern Territory (NT) is among the regions in Australia and the world with the highest solar radiation intensities. The NT has many mine sites which consume significant amount of fossil fuel with consequent greenhouse gas (GHG) emissions. The environmental concern related to the fossil fuel consumption and availability of immense solar energy resource in the NT open the possibilities for considering the provision of power to the mining sites using proven solar technologies. Concentrating solar power (CSP) systems are deemed as the potential alternatives to current fossil fuel based generating systems in mining industry in the NT. The finding is based on consideration of the major factors in determining the feasibility of CSP system installation, with particular reference to the NT mine sites. These are plant design requirements, climatic, environmental, and other requirements, and capital and operating costs. Based on these factors, four mine sites have been identified as having the potential for CSP plants installation. These are McArthur River Mine, Ranger Mine, Northern Territory Gold Mines, and Tanami Operations. Each site could be served by one CSP plant to cater for the needs of mining operation and the local communities.

Abstract:
In mine power systems, false operation and failure operation of relays in parallel supply lines often take place when single phase grounding fault occurs. A novel method based on phase-to-phase current difference is proposed as line selection criterion in this paper. The method builds on that the phase-to-phase current difference based on fault phase in fault line is equal to the grounding fault current while the phase-to-phase current difference based on fault phase in sound lines is equal to zero. Thus the fault line was selected by the biggest phase-to-phase current difference of the lines. The simulation results using PSCAD and experiment results show that the method has a high accuracy and a great ability of anti-disturbance. It is quite effective when single-phase-to-earth fault occurs in one of the parallel supply lines. It also applies to any distribution system with different grounding patterns and won’t be affected by the value of grounding resistance or the degree of fault phase.

Abstract:
In this paper, Mine Blast Algorithm (MBA) has been intermingled with Harmony Search (HS) algorithm for solving optimal reactive power dispatch problem. MBA is based on explosion of landmines and HS is based on Creativeness progression of musicians – both are hybridized to solve the problem. In MBA Initial distance of shrapnel pieces are reduced gradually to allow the mine bombs search the probable global minimum location in order to amplify the global explore capability. Harmony search (HS) imitates the music creativity process where the musicians supervise their instruments’ pitch by searching for a best state of harmony. Hybridization of Mine Blast Algorithm with Harmony Search algorithm (MH) improves the search effectively in the solution space. Mine blast algorithm improves the exploration and harmony search algorithm augments the exploitation. At first the proposed algorithm starts with exploration & gradually it moves to the phase of exploitation. Proposed Hybridized Mine Blast Algorithm with Harmony Search algorithm (MH) has been tested on standard IEEE 14, 300 bus test systems. Real power loss has been reduced considerably by the proposed algorithm. Then Hybridized Mine Blast Algorithm with Harmony Search algorithm (MH) tested in IEEE 30, bus system (with considering voltage stability index)- real power loss minimization, voltage deviation minimization, and voltage stability index enhancement has been attained.

Full text
Abstract:
The continuing trend toward larger longwall mining systems has resulted in the utilization of higher system voltages. The increase in system voltage levels has caused the industry to face complexities not experienced with the lower-voltage systems. One such complexity arises from the larger system capacitance that results from the outby configuration commonly used on 4,160-V longwall power systems. Simulations show that during a line-to-ground fault, the larger system capacitance can cause a situation where the ground current sensed by the ground-fault relays in unfaulted circuits is greater than the mandated ground-fault relay pick-up setting. Simulations show that ground-fault relaying selectivity is potentially lost as a result of this situation. Two alternatives were identified which could improve ground-fault relaying selectivity. They are: the application of a directional relaying scheme and increasing the ground-fault relay pick-up setting. It was determined that directional relays have an application to high-voltage longwall power systems as the ground current sensed by the relay in the unfaulted circuits is out of phase with the ground-fault current sensed by the relay in the faulted circuit. Furthermore, it was determined that raising the ground-fault relay pick-up setting by a factor of eight would also improve ground-fault relaying selectivity. A safety analysis considering the potential for electrocution and the power dissipated by the maximum fault resistance showed that increasing the pick-up setting by a factor of eight would have no detriment to safety. Therefore, either method would improve ground-fault relaying selectivity on high-voltage longwall mining systems, yet because of the escalating size of longwall systems, a directional relaying scheme is a longer term solution.

Abstract:
The great innovations of the last century have ushered continuous progress in many areas of technology, especially in the form of miniaturization of electronic circuits. This progress shows a trend towards consistent decreases in power requirements due to miniaturization. According to the ITRS and industry leaders, such as Intel, the challenge of managing and providing power efficiency still persist as scaling down of devices continues. A variety of power sources can be used in order to provide power to low power applications. Few of these sources have favorable characteristics and can be designed to deliver maximum power such as the novel mini notched turbine used as a source in this work. The MiNT is a novel device that can be used as a feasible energy source when integrated into a system and evaluated for power delivery as investigated in this work. As part of this system, a maximum power point tracking system provides an applicable solution for capturing enhanced power delivery for an energy harvesting system. However, power efficiency and physical size are adversely affected by the characteristics and environment of many energy harvesting systems and must also be addressed. To address these issues, an analysis of mini notched turbine, a RF rectenna, and an enhanced maximum power point tracking system is presented and verified using simulations and measurements. Furthermore, mini notched energy harvesting system, RF rectenna energy harvesting system, and enhanced maximum power point tracking system are developed and experimental data analyzed. The enhanced maximum power point tracking system uses a resistor emulation technique and particle swarm optimization (PSO) to improve the power efficiency and reduce the physical size. This new innovative design improves the efficiency of optimized power management circuitry up to 7% compared to conventional power management circuits over a wide range of input power and range of emulated resistances, allowing more power to be harvested from small energy harvesting sources and delivering it to the load such as smart sensors. In addition, this is the first IC design to be implemented and tested for the patented mini notched turbine (MiNT) energy harvesting device. Another advantage of the enhanced power management system designed in this work is that the proposed approach can be utilized for extremely small energy sources and because of that the proposed work is valid for low emulated resistances. and systems with low load resistance Overall, through the successful completion of this work, various energy harvesting systems can have the ability to provide enhanced power management as the IC industry continues to progress toward miniaturization of devices and systems.

Abstract:
The design, construction and testing of a reverse-osmosis (PV-RO) desalination system for fresh water shortage area is presented. The system operates from salt water or brackish water and can be embedded in a renewable energy power supply system, since many fresh shortage areas are remote and isolated. Special attention is given to the energy efficiency of small-scale reverse osmosis desalination systems. Limitations of conventional control strategy using toggle control are presented. Based on this, an objective of creating a small-scale reverse osmosis desalination system was set out. Initially, the background information is presented. This includes the natural resources crisis and main desalination technologies and the viability of the integration with renewable energy source. A reverse osmosis (RO) desalination system was assembled and set up at the Curtin University of Technology, Perth, Western Australia Supervisor Control And Data Acquisition (SCADA) system was built using a Human Machine Interface software and a programmable logic controller (PLC). Instrumentation that included signal conditioners was made in analysis of the system characteristics. Initial testing of the system was conducted after the system design and configuration was accomplished. Testing results were used as a guideline for the development of the whole system.
Modelling and simulation of the system components in MATLABSimulink is presented, together with a discussion of the control systems modelling and design procedure, in which the aim was to improve the efficiency of the reverse osmosis system. Simulations show the designed reverse osmosis system with Proportional Integral and Derivative (PID) controller has better performance than other controllers. This consequently leads to a lower overall cost of the water, as well as reducing full maintenance cost of the electric drives in the reverse osmosis unit. Additionally, the configuration of the remote control system through General Package Radio System (GPRS) network is depicted. After the PID control algorithm was programmed into the Programmable Logic Controller (PLC), system experiments were carried out in short durations and long durations. System performance was monitored and experimental results prove that the new control strategy applied increase the water productivity and is able to improve the system efficiency up to 35%. Based on the data obtained from the simulations and experiments, Mundoo Island was chosen to be the location for a case study. The electric load profile of the island was derived from the Island Development Committee in Mundoo.
A water demand profile was created and modelled in Matlab to be the input of the reverse osmosis system. The electric load of the reverse osmosis system was generated from Matlab simulation. This result was entered in Hybrid Optimisation Model for Electric Renewables (HOMER) simulator. Having the designed RO unit as one of the electric loads, the entire remote area power supply (RAPS) system was tested in simulations which shows the energy cost is AUS$0.174 per kWh, lower than the Island Development Committee budget estimation of AUS$0.25 per kWh. The cost of the water treatment is very promising at AUS$0.77 per m3.

Abstract:
Load, haul and dump machines (LHDs) are commonly used in underground mines around the world. The machines are used to transport fragmented ore after blasting in the ore body. The main propellant used is diesel which accounts for a large part of the diesel consumed in mines today. This master thesis is a pilot study for further work to be done by LTU and Atlas Copco in a project called SIMS or Sustainable Intelligent Mining Systems, where the aim is to physically demonstrate diesel free LHDs doing productive work in mines. The objective of the thesis was to assess if the integration of battery-powered LHD machines is plausible in today’s underground mines. The aims were to map the current state of the production and to perform risk and job analysis of the new technology in the current systems. A theoretical framework was constructed with focus on safety, risk, hazards and change in work content. Social acceptance was then researched to be able to analyze how the new technology is received. Data gathering was done through interviews, observations, a focus group and reviewing documents while visiting Atlas Copco and two underground mines in Sweden. Diesel and electric-powered LHDs were studied in the mines and battery-powered LHDs were studied at Atlas Copco. The results present the current state of diesel, electric and battery-powered LHDs. How the machines are used in the visited mines and the identified risks with the work is presented along with the mapping of the battery system being developed by Atlas Copco. New risks that the battery system will bring to the work environment were identified using energy and deviation analyzes. The change in work content was discussed using the information from the visits and identifying what tasks will change, disappear and be added with the new technology. A large part of the thesis was analyzing the results with support from the theoretical framework. The analysis showed that a switch from diesel to battery-power would improve the overall health and safety inside the mines. A switch does not change the skill needed to operate the machines but can increase the qualifications for the service personnel. The main obstacles, in terms of social acceptance, with implementing the battery systems in the current state are that the need for constant battery exchange would cause problems in the production, the prejudice that the batteries would increase the consequences of a fire and the initial cost of making the switch. Recommendations for Atlas Copco going forward in the SIMS project were made. They need to emphasizing the safety of the technology to the users, developing the battery exchange so it can be done closer to the stopes and involve the operators in the projects of SIMS to help them understand the benefits it will have on them directly.
Gruvlastmaskiner (LHD) används ofta i gruvor runt om i världen. Maskinerna används för transportera fragmenterade malm efter malmen sprängts. Det huvudsakliga drivmedlet som används är diesel, som står för en stor del av den diesel som förbrukas i gruvor idag. Detta examensarbete är en pilotstudie för ytterligare arbete som ska utföras av LTU och Atlas Copco i ett projekt som heter SIMS eller Sustainable Intelligent Mining Systems. Syftet är att fysiskt demonstrera dieselfria LHD-maskiner göra produktivt arbete i gruvor. Syftet med examensarbetet var att bedöma om integrationen av batteridrivna LHD-maskiner är möjligt i dagens underjordiska gruvor. Målet var att kartlägga den aktuella produktionssituationen och att utföra risk- och arbetsanalyser av den nya tekniken i nuvarande system. En teoretisk referensram konstruerades med fokus på säkerhet, risk och förändring i arbetsinnehåll. Social acceptans undersöktes sedan för att kunna analysera hur den nya tekniken tas emot. Datainsamlingen gjordes genom intervjuer, observationer, en fokusgrupp och granskning av dokument givna vid besök på Atlas Copco och två underjordiska gruvor i Sverige. Diesel- och el-drivna maskiner studerades i gruvorna och batteridrivna studerades hos Atlas Copco. Resultaten presenterar det nuvarande läget för diesel, elektriska och batteridrivna LHDmaskiner. Hur maskinerna används i de besökta gruvorna och de identifierade riskerna med arbetet presenteras tillsammans med kartläggningen av batterisystemet som utvecklas av Atlas Copco. Nya risker med batterisystemet identifierades med hjälp av energi- och avvikelsesanalyser. Ändringarna i arbetsinnehåll diskuterades med hjälp av informationen från besöken och klargör vilka uppgifter som ska förändras, försvinnas och läggas till med den nya tekniken. En stor del av arbetet var att analysera resultaten med stöd från den teoretiska referensramen. Analysen visade att bytet från diesel till batterier skulle förbättra hälsan och säkerheten i gruvorna. Teknologibytet förändrar inte den färdighet som krävs för att kunna manövrera maskinerna men kan öka kvalifikationerna för servicepersonalen. De viktigaste hindren när det gäller social acceptans med att implementera batterisystemen i det nuvarande tillståndet är att behovet av konstant batteribyte skulle orsaka problem i produktionen, fördomarna om att batterierna skulle öka konsekvenserna av en brand och de initiala kostnaderna att göra ett byte. Rekommendationer för Atlas Copco för fortsatt arbete i SIMS-projektet gjordes. De behöver klargöra säkerheten hos den nya teknik för användarna, utveckla batteribytet så att det kan göras närmare produktionen och involvera operatörerna i SIMS-projekten för att hjälpa dem att förstå de fördelar som det kommer att ha på dem direkt.

Abstract:
Fuel supply issues are a major concern in remote island communities and this is an engineering field that needs to be analyzed in detail for transition to sustainable energy systems. Power generation in remote communities such as the islands of the Maldives relies on power generation systems primarily dependent on diesel generators. As a consequence, power generation is easily disrupted by factors such as the delay in transportation of diesel or rises in fuel price, which limits shipment quantity. People living in remote communities experience power outages often, but find them just as disruptive as people who are connected to national power grids. The use of renewable energy sources could help to improve this situation, however, such systems require huge initial investments. Remote power systems often operate with the help of financial support from profit-making private agencies and government funding. Therefore, investing in such hybrid systems is uncommon. Current electrical power generation systems operating in remote communities adopt an open loop control system, where the power supplier generates power according to customer demand. In the event of generation constraints, the supplier has no choice but to limit the power supplied and this often results in power cuts. Most smart grids that are being established in developed grids adopt a closed loop feedback control system. The smart grids integrated with demand side management tools enable the power supplier to keep customers informed about their daily energy consumption. Electric utility companies use different demand response techniques to achieve peak energy demand reduction by eliciting behavior change. Their feedback information is commonly based on factors such as cost of energy, environmental concerns (carbon dioxide intensity) and the risk of black-outs due to peak loads. However, there is no information available on the significant link between the constraints in resources and the feedback to the customers. In resource-constrained power grids such as those in remote areas, there is a critical relationship between customer demand and the availability of power generation resources. This thesis develops a feedback control strategy that can be adopted by the electrical power suppliers to manage a resource-constrained remote electric power grid such that the most essential load requirements of the customers are always met. The control design introduces a new concept of demand response called participatory demand response (PDR). PDR technique involves cooperative behavior of the entire community to achieve quality of life objectives. It proposes the idea that if customers understand the level of constraint faced by the supplier, they will voluntarily participate in managing their loads, rather than just responding to a rise in the cost of energy. Implementation of the PDR design in a mini-grid consists of four main steps. First, the end-use loads have to be characterized using energy audits, and then they have to be classified further into three different levels of essentiality. Second, the utility records have to be obtained and the hourly variation factors for the appliances have to be calculated. Third, the reference demand curves have to be generated. Finally, the operator control system has to be designed and applied to train the utility operators. A PDR case study was conducted in the Maldives, on the island of Fenfushi. The results show that a significant reduction in energy use was achieved by implementing the PDR design on the island. The overall results from five different constraint scenarios practiced on the island showed that during medium constrained situations, load reductions varied between 4.5kW (5.8%) and 7.7kW (11.3%). A reduction of as much as 10.7kW (15%) was achieved from the community during a severely constrained situation.

Abstract:
We introduce a quantum neural network, QNN, that can represent labeled data, classical or quantum, and be trained by supervised learning. The quantum circuit consists of a sequence of parameter dependent unitary transformations which acts on an input quantum state. For binary classification a single Pauli operator is measured on a designated readout qubit. The measured output is the quantum neural network’s predictor of the binary label of the input state. We show through classical simulation that parameters can be found that allow the QNN to learn to correctly distinguish the two data sets. We then discuss presenting the data as quantum superpositions of computational basis states corresponding to different label values. Here we show through simulation that learning is possible. We consider using our QNN to learn the label of a general quantum state. By example we show that this can be done. Our work is exploratory and relies on the classical simulation of small quantum systems. The QNN proposed here was designed with near-term quantum processors in mind. Therefore it will be possible to run this QNN on a near term gate model quantum computer where its power can be explored beyond what can be explored with simulation.
