The Analysis Of Static Performance And The Study Of Dynamic Simulation Of Direct Voltage Type SVC

With the strength of trend of different areas power net interconnection of modern power system, the safety and stability become more important. In order to improve the safety and economy, a lot of advanced FACTS devices which are able to Control others speedily are applied abroad in the power system.In this dissertation, the ways of reactive power compensation of the current power system are compared in detail. Considering the low power factor of electric traction load and larger harmonic ingredients, a new type of static var compensator —the direct voltage type SVC compensation devices are developed. The main circuit of the direct voltage type SVC consists of the autotransformer with average voltage, fixed branch which can compensate the reactive power and filter the harmonic, dynamic branch which can compensate the reactive power and filter the harmonic, capacitive AC thyristor no contact switch and the measuring and controlling system of...
