Abstract:

Includes bibliographical references.<br>The aim of this thesis is to produce a load compensator for a three-phase system. It should be simple, accurate and affordable. The three-phase load compensator design is based on a more recent definition of power factor. Attempts to establish a universally acceptable definition can be traced as early as 1920 at the 36th Annual convention of the American Institution of Electrical Engineers. Subsequently, a number of definitions have been adopted by different scholars. Each definition can lead to a different compensator solution. This problem, for example

Abstract:

Voltage and current unbalance are major problems in distribution networks, particularly with the integration of distributed generation systems. One way of mitigating these issues is by injecting negative sequence current into the distribution network using a Static Synchronous Compensator (STATCOM) which normally also regulates the voltage and power factor. The benefits of modularity and scalability offered by Modular Multilevel Cascaded Converters (MMCC) make them suitable for STATCOM application. A number of different types of MMCC may be used, classified according to the sub-module circuit

Abstract:

Hybrid stepper motors are a common type of electric motor used throughout industry thanks to its low-cost, high torque at low speed and open loop positioning capabilities. However, a closed loop control is often required for industrial applications with high precision requirements. The closed loop control can also be used to lower the power consumption of the motor and ensure that stalls are avoided. It is quite common to utilise a large and costly position encoder or resolver to feedback the position signal to the control logic. This thesis has explored the possibility of using a low-cost pos

Abstract:

Voltage is one of the most important parameters for electrical power networks. The Distribution Network Operators (DNOs) have the responsibility to maintain the voltage supplied to consumers within statutory limits. On-Load Tap Changer (OLTC) transformer equipped with Automatic Voltage Control (AVC) relay is the most widely used and effective voltage control device. Due to a variety of advantages of adding Distributed Generation (DG), more and more distributed resources are connected to local distribution networks to solve constraints of networks, reduce the losses from power supply station to

Abstract:

It is well known that real op-amps do not share most of the desirable characteristics of an ideal one, particularly those of gain and output impedance. When presented with a capacitive load, such as a MOSFET or ADC, feedback in an op-amp circuit can quickly become unstable. This thesis studies and characterizes an op-amp’s output impedance and how its interaction with this type of load creates a parasitic pole which leads to instability. Applying ideas from feedback control theory, a model for studying the problem is developed from which a generalized method for compensating the undesirable ci

The purpose of this thesis report is to investigate challenges related to railway electrification. Inac-railway systems, trains are most often single-phase loads, which can create significantunbalances in the grid, when fed directly from two adjacent phases. To enhance power quality atthe railway feeding point, one alternative is to design the system such as the power is fed to thecatenary through Static Frequency Converters (SFCs), which can be a costly solution. Anotheroption is to use Static Compensators (STATCOMs) in shunt connections, handling only theunbalanced amount of power, in order

Abstract:

A methodology to determine the optimal capacitor locations and sizes to minimize line loss on a radial distribution system was developed in this work. Both the power loss index (PLI)-based approach and the loss sensitivity coefficient-based approach were comparatively studied to determine the optimal capacitor location. The index-based approach combined with a genetic algorithm was used to determine the capacitor sizes. After reactive power compensation voltage-dependent loads consume more power because of the increase in node voltage; therefore, customers pay more for their electricity while

Abstract:

The world today is constantly growing, creating a need of new roads and residential areas. New constructions lead to an increased load onto the soil, which can result in deformations when the soil layers underneath are compressed. To reduce the increased load on the soil, a compensated foundation can be used. This method is based on the principle that the load from the construction will be compensated by the excavated soil, often replaced by a lightweight material. As an example, this method can be used in areas with great clay layers and in sensitive projects where the rise of deformations ca

The agency theory literature implies the pay-performance based managerial compensation can relieve the agency problem between shareholders and managers. As the interests of shareholders and managers are aligned, managers have incentive to invest in best projects and hence to improve firms’ performance. While the use of equity compensation to managers may reduce the agency cost between managers and shareholders, its impact on agency cost of debts is ambiguous. On the one hand, a large portion of equity compensation discourages risk-averse managers to invest in risky investment and hence reduce

Abstract:

Contrary to other forms of outside financing, the announcement of a bank loan agreement prompts a positive and significant market return. Throughout the literature, bank loans are deemed special and unique due to multiple benefits accruing to bank borrowers. The short-term positive market reaction is however inconsistent with the long-term underperformance of borrowing firms (Billet et al., 2006). We find that unlike shareholders, CEOs gain from the bank loan relation over the long-term. Specifically, we find that bank loan agreement elicits a significant increase in total compensation through

Therefore we add the compliance motion to control the robot control system. The impedance control can not comply with the difference of the original external environment, because the control method can’t self-adjust the parameters of impedance control system.

However, when the work environment is changing or the error of position command happened, both robot and environment could be damaged. It is necessary to join compliance control. In human-robot cooperation task, manipulator has to work with the guidance of operator. Manipulator must be have the ability to comply with external forces, and generates compliance ability. In this study, impedance control with load compensation is proposed. Impedance control is applied to manipulator

The PV power system is composed of an interleaved DC/DC converter and a three-level neutral-point clamped (NPC) inverter. Moreover, the PV power system possesses the smart inverter function, in which the output active and reactive powers of the PV inverter are predetermined by a power factor according to grid codes of the utilities.

M.TECH<br>The demand of the electrical energy is ever increasing and it is desired to use the existing transmission network to its thermal stability limits. The transmission capacity can be increased by the compensation at appropriate locations. The reactive power compensation plays an important role in the planning of power system. This ensures a satisfactory voltage profile and a reduction in power and energy losses within the system. Reactive power also maximizes the real power transmission capability of transmission lines, while minimizing the cost of compensation. In this thesis, the re

碩士<br>國立成功大學<br>電機工程學系<br>103<br>In this thesis, a three-phase inverter providing automatic voltage compensation for unbalanced or nonlinear load under stand-alone operation is presented. An ideal load-side inverter should provide constant amplitude, frequency, and sinusoidal voltage at point of common coupling (PCC). Without the stiff sinusoidal voltage support by grid, voltage quality at PCC is heavily affected by the type of loads. The nonlinear loads could produce voltage harmonics that degrade voltage quality. To maintain voltage quality at certain level, a proportional-resonant (PR) cont

Abstract:

Power consumption is the primary concern in battery-operated portable applications. Buck converters have gained popularity in powering portable devices due to their compact size, good current delivery capability and high efficiency. However, portable devices are operating under light load condition for the most of the time. Conventional buck converters suffer from low light-load efficiency which severely limits battery lifetime. In this project, a novel technique for buck converter is proposed to reduce the switching loss by reducing the effective input supply voltage at light load. This is a
