Simulation of 3 Phase, 24 Pulse GTO Converter for Flow Control of Transmission System

Gate Turn off GTO thyristor based power control controller for flow control of transmission system is used to regulate voltage and reactive power improment. GTO thyristor switching devices with high power handling capability and the advancement of the other type of power semiconductor devices such as IGBTs, MOSFETs, Ideal switch and so on have led to the development of fast controllable reactive power source utilizing new electronic switching and converter technology. Nowadays, the development of a large capacity Gate Turn off thyristor has made it possible to manufacture self commutated converter employing GTO thyristor for power applications. At present, most of the research on GTO thyristor has focused on their use in power electronic systems at high switching frequencies. GTO thyristor enable the design of the solid state shunt equipment based upon switching technology. The improved rating of GTOs made possible the use of voltage sourced converter VSC in power system applications. In this paper, GTO based voltage source converter VSC is used in high power Flexible AC Transmission Systems FACTS which are used to control power flow on transmission grids. It can be used to build a model of shunt or series static compensator STATCOM or SSSC or, using two such converters, a combination of shunt and series devices known as Unified Power Flow Controller UPFC . This paper has shown a basic application of MATLAB SimPowerSystems programming for 24 pulse GTO converter STATCOM.
