Abstract:

The thesis discusses the development of closed loop system to control the DC voltage for 200 kW induction generator rated at a speed of 62000 RPM under different load conditions. The voltage regulation has been implemented using PI controller. A gain scheduling control algorithm has been developed to select the appropriate controller gains with respect to the generator load. Further, a relationship between the generator loads and the controller gains has been established. This relationship has been modeled using adaptive control technique to vary the gains automatically at any load condition.

Abstract:

This thesis aims to establish computer methods for the transient stability analysis of electric power systems which operate isolated from the large interconnected system. A typical isolated system is characterized by a compact network in which the size of the load is relatively large when compared to the total, installed generation capacity. The stability problems are thus more severe for this system than for the grid-type system. This results in the need for more accurate representations for the system components in the computer studies. This work considers particularly the prime mover and th

As one of the oldest machine topologies, the concept of synchronous reluctance (REL) machine can be traced back as early as 1900s. In the last 20 years, particularly, the REL machines have attracted more and more attention in both academic and industrial fields. Without permanent magnets and rotor bars, the rotor construction of the REL machine is more robust than either permanent magnet (PM) machines or induction machines (IMs). In addition, it achieves the merits of low cost, low maintenance, and high reliability. All these features reveal the REL machine to be an attractive alternative to t

Abstract:

Due to the rapid growth of grid-tied solar photovoltaic (PV) systems in the generation mix, the distribution grid will face complex operational challenges. High PV penetration can create overvoltages and voltage fluctuations in the network, which are major concerns for the grid operator. Traditional voltage control devices like switched capacitor banks or line voltage regulators can alleviate slow-moving fluctuations, but these devices need to operate more frequently than usual when PV generation fluctuates due to fast cloud movements. Such frequent operations will impact the life expectancy o

Abstract:

Determination of the placement and rating of transformers and feeders are the main objective of the basic distribution network planning. The bus voltage and the feeder current are two constraints which should be maintained within their standard range. The distribution network planning is hardened when the planning area is located far from the sources of power generation and the infrastructure. This is mainly as a consequence of the voltage drop, line loss and system reliability. Long distance to supply loads causes a significant amount of voltage drop across the distribution lines.

This project was a step forward in improving the voltage profile of traditional low voltage distribution networks with high photovoltaic generation or high peak demand.

The placement of DVR in the network is optimised in order to minimise its power rating and cost. In addition, new approaches were developed for grid synchronisation and control of DVR which are integrated with the voltage qual

For supplying stable DC-link voltage to load, a suitable voltage regulation circuit is designed based on the integrate system performance assessment. Electrical and mechanical parameters in this refined STLG design are involved to analyze the operational behaviors through magnetic equivalent circuit analysis at different operating modes.

Abstract:

Of all the renewable energies, wind power is proliferating and it now plays a significant part in the power supply. The system known as Doubly Fed Induction Generator (DFIG) is the most popular wind turbine, because it plays a very significant role in enhancing low voltage ride through (LVRT) capability. Ancillary services such as voltage control and reactive power capability are the main concerns in wind power control systems and need to be managed in detail and with great care. The lack of reactive power during a fault period can result in instability in generators and/or disconnection of a

Abstract:

The squirrel-cage induction machine is very attractive for small and medium power generation schemes because of its low cost, robustness and high power density (W/kg). However, the magnitude and the frequency of the generated voltage depend upon the rotor speed, the amount of capacitive excitation, and the load in stand-alone systems with unregulated prime movers. A common approach for providing regulated voltage and frequency to the load is the use of an asynchronous link (ac-dc-ac) power electronic converter. The main disadvantage of this scheme is that the two series connected ac-dc convert

This paper is to modify some circuit based on product specification in order to make balance of cost and specification. We start to study how to use the least cost to reduce Locking time and increase locking speed of phase lock loops without modifiying original circuit characteristics. In addition, VCO circuit in the system is a high pass filter. Noise of VCO will make contribution to output frequency. So, we must use technique of designi

Three phase induction generators provide the desired electric power in a wind energy conversion system. Induction machines are not commonly employed as generators except in the case of wind farms due to their unsatisfactory voltage regulation. The purpose of this thesis is to analyze and design the Dynamic Voltage Regulator(DVR) for a wind energy conversion system with an induction

Wind generation units without proper reactive compensation devices may induce voltage fluctuations to the system. Moreover, voltage variations from transmission system may lead to voltage sags at wind generator terminal and frequent tripping would occur, which would reduce the life time of wind generators. Using fixed capacitor for reactive power compensation has some problems, for example, insufficient

The regulator could produce two different output voltage levels for the same output by using an external selection signal. The proposed LDO structure is suitable for a power management system that required more than one supply voltage level with small area. The output voltage levels are 1V and 2.5V in this design. Our proposed dual output voltage level LDO linear regulator consists of a novel two-level reference voltage generator, a fast discharging path for the swit

For relatively long lines, line charging is high and thus higher voltage limits reached at low loading. It follows then that it is a challenge to maintaining the voltages between the acceptable limits for relatively long lines. This dissertation highlights the problems experienced when load varying from very low to very high is supplied by very long parallel lines of different impedance characteristic.

It can be formed as area power supply system or can be connected in parallel to large-scale power system. For distribution in the past, the Taipower would supply a one-way power, therefore this was simpler in respect of control, management, repair or fee collection.
