The paper summarizes new control designs developed at Washington State University for the control of existing SVC’s, and TCSC owned by Bonneville Power Administration. The new controls are primarily aimed at improving transient stability of the WSCC western electric power system. The proposed controls are heuristic and are nonlinear. They are shown to be very effective in increasing the operati...

Each of the eight 1.2 MW RF klystrons for the PEP-II storage rings require a 2.5 MVA DC power supply of 83 Kv at 23 amps. The design for the suply was based on three factors: low cost, small size to fit existing substation pads, and good protection against damage to the klystron including klystrong gun arcs. The supply uses a 12 pulse 12.5 KV primary thyristor “star point controller” with prima...

The wind energy stands out to be one of the most promising new sources of electrical power in the near term. The latest technological advancements in wind energy conversion and an increased support from governmental and private institutions have led to increased wind power generation in recent years. Wind power is the fastest growing renewable source of electrical energy hence it has become nec...

Classification, essential properties, important applications and developement of power semiconductor devices will be explained. Some common power semiconductor devices, power metal oxide semiconductor field-effect transistor (MOSFET), thyristor and some new power devices will be described and discussed.

This paper presents two new Particle swarm optimization methods to solve optimal power flow (OPF) in power system incorporating flexible AC transmission systems (FACTS). Two types of FACTS devices, thyristor-controlled series capacitor (TCSC) and thyristor controlled phase shifting (TCPS), are considered. In this paper, the problems of OPF with FACTS are solved by using particle swarm optimizat...

In a deregulated electricity market, it may always not be possible to dispatch all of the contracted power transactions due to congestion of the transmission corridors. This paper presents a transmission lines congestion management in a restructured market environment using a combination of demand response and Thyristor controlled series compensators (TCSCs). The overall objective of FACTS devi...

This paper presents a new approach for the protection of Thyristor-Controlled Series Compensator (TCSC) line using Support Vector Machine (SVM). One SVM is trained for fault classification and another for section identification. This method use three phase current measurement that results in better speed and accuracy than other SVM based methods which used single phase current measurement. This...
