Streszczenie:

Series compensation techniques can be very effective when applied in an electrical network to increase the power transfer capacity of existing power lines. Distributed Static Series Compensation (DSSC) is a power electronics based series compensation scheme in which a DSSC device comprises of a single-phase H-bridge voltage source converter, a dc link capacitor and a low pass filter suspended from the power line via a single turn transformer. The application of DSSC in the 11kV distribution network is investigated in this thesis. This is followed by a study of existing control strategies emplo

Streszczenie:

This research work proposes intensive study and mathematical modelling analysis of transformer-less quasi Z-source inverter (qZSI) based static synchronous compensator (STATCOM) system. In this work, a single-phase qZSI is acted as a STATCOM system to compensate the grid reactive power at the point of coupling under different loading conditions. A new controller-based lead compensator is developed to achieve fast DC-link voltage balance across each qZS network. Simulation studies are conducted to evaluate the controller’s performance.

Electrical power quality is essential in the effective transmission and distribution of power to consumers. With the increase in non-linear loads it is becoming more prevalent to maintain the quality of power supplied. Voltage sagging or swelling and power factor are two of the major power quality issues. By introducing a static synchronous compensator (STATCOM) into a system these power-quality issues can be significantly reduced and maintained effectively.

Power flow (PF) control can increase the utilization of the transmission system and connect lower cost generation with load. While PF controllers have demonstrated the ability to realize dynamic PF control for more than 25 years, PF control has been sparsely implemented. This research re-examines PF control in light of the recent development of fractionally-rated PF controllers and the incremental power flow (IPF) control concept. IPF control is the transfer of an incremental quantity of power from a specified source bus to specified destination bus along a specified path without influenc

碩士<br>國立臺灣大學<br>電機工程學研究所<br>95<br>Due to the rise in oil price and the need to reduce carbon dioxide in order to alleviate the greenhouse effect, green energy such as wind-power electricity generation received much attention in recent years. Because the speed of the wind is not regular in wind-power electricity generation, induction machines are often used. The purpose of this thesis is to design and analyze the static synchronous compensator (STATCOM) which regulates the voltage of an induction generator system. With a direct current capacitor to offer the voltage source, a three-phase volta

Submitted in fulfillment of the requirements for the degree of Master of Engineering in Electrical Power Engineering, Durban University of Technology, Durban, South Africa, 2017.<br>Voltage instability and increased power loss on transmission lines are major challenges in power transmission due to ever increasing load growth. This work investigates the effect of Static Synchronous Compensator (STATCOM) to mitigate power losses and enhance the voltage stability of a transmission system. STATCOM, a shunt-connected power electronic device, operate as a Voltage Source Converter (VSC) to improve po

Various FACTS devices have been widely used to solve the problems of transmission system at present. The STATCOM is used in this study to improve the problem of lacking voltage stability . A novel optimized algorithm for alternating GAPSO and PSODE, called AGPD, is developed to determine the optimal positions and capacities for STATCOMs under various operating conditions

Severe faults in the system may ever cause voltage collapse and generator instability. The purpose of this thesis is to investigate terminal voltage stability of wind generators when the power sys

Research Doctorate - Doctor of Philosophy (PhD)<br>This thesis presents the control and performance of a Cascaded H-Bridge photovoltaic power system. The cascaded H-Bridge multilevel converter offers a number of attractive features for use in photovoltaic power systems. They provide opportunities for increases in efficiency, superior tracking of the maximum available power and direct connection to higher voltages. This system topology is a relatively immature technology and a number of key areas exist for research. In particular, the individual maximum power point tracking performance requires

It becomes important to fully utilize the existing transmission system to supply load demand as much as possible, thus eliminating or reducing the need for new transmission investment. Flexible AC Transmission System (FACTS) technology provides an alternative to fully utilize the existing transmission lines as well as new and upgraded lines, by controlling power and also enhancing the power transfer capability of transmission lines.

The focus of this research is on deriving small signal stability models for different Flexible AC Transmission Systems devices by introducing a simple systematic method that is applicable to any dynamic device. Two different small signal models for Unified Power Flow Controllers are introduced. One model is called the power control mode and the other model is the voltage control mode. The two models are compared from transient stability point of view to show the necessity of developing both models for UPFC. The thesis also shows how to derive the small signal stability model of Static Synch

Small signal oscillation has been always a major concern in the operation of power systems. In a generator, the electromechanical coupling between the rotor and the rest of the system causes it to behave in a manner similar to a spring mass damper system. Following any disturbance, such as sudden change in loads, actuations in the output of turbine and faults etc. it exhibits an oscillatory behaviour around the equilibrium state. The use of fast acting high gain AVRs and evolution of large interconnected power systems with transfer of bulk power across weak transmission links have further aggr
