Static Var Compensator of controller system and Controlling Method Thereof

摘要

The present invention provides simplification of signal transmission and reception between a control device of a static var compensator (SVC) and a valve. According to an embodiment of the present invention, the control device of the SVC comprises: a monitoring control part receiving a control signal from a system controller, and generating an error existence/nonexistence signal; a valve signal processing part receiving each of databack signals from each of a plurality of valves, and generating a valve state signal; a CPU control part generating a normal state information signal based on the error existence/nonexistence signal and the valve state signal; and a roll call signal output control part receiving the normal state information signal, and transmitting a roll call signal to each of the plurality of valves.
