Flexible AC transmission system compensation on a utility transmission system

Power system security can be increased by the use of flexible AC Transmission System devices, FACTS, in transmission systems experiencing high power flows. This thesis presents an analysis of one of these devices, namely, a Thyristor Controlled Series Compensator, TCSC, as applied to the Nevada Power Company 230kV southern transmission network. The methodology for choosing the appropriate location for the device and equations to accurately analyze the TCSC are developed. The analysis of the utility network is divided into three stages: (1) development of a benchmark, pre-TCSC case, establishing the real and reactive power transfer capabilities of the network, (2) identification of the critical contingencies at increased power transfers, and (3) evaluation of a TCSC device to mitigate the identified problem area. Results indicate that the application of a TCSC to the McCullough-Arden #2 230kV transmission line will increase bulk power transfers into this area by 108 MW while mitigating a line outage and releasing increased power flows on a critically loaded line. This study also shows that the power system modeled will reach a steady-state condition within 18 cycles after the TCSC is inserted.
