Static Var Compensator

Rongxin Power Electronic Co Ltd is one of the biggest static VAR compensator (SVC) manufacturers in the world. It possesses the experience of manufacturing SVCs for 12 years. More than 500 sets of SVCs manufactured by the company are widely used in China and Asia. It has the biggest amount of SVC applications in the world in 2005, 2006 and 2007 for three consecutive years. SVC is a shunt-connected static VAR generator or absorber whose output can be adjusted to exchange capacitive or inductive current to maintain or control specific parameters of the electrical power system (typically bus bar voltage or power factor). It is the best solution to the problems of power quality. TCR type SVC: this is connected to the system in a specified manner. Capacitors and filters provide fixed capacitive reactive power. TCR provides inductive reactive power, which is determined by the current flows through the TCR. The system must try to satisfy the equation QN=Qv-QNc+Qtcr=0, so that the power factor is a constant value and there will be no fluctuation of the voltage. The most important is to control the firing angle of the thyristors prospectively to obtain the needed currents in order to provide the needed reactive power.
