Abstract
Static Var Compensator(SVC) based on Thyristor Controlled Reactor(TCR)has good compensation-perofrmance for rapid changing load, so it has become a hotspot in recent years.
In this paper、all equipments of the SVS family is introduced, the working principle and control on FC-TCR is searched,Based on this theory , a dynamic Var compensator controller is designed with AT89S54 microcomputer.Control circuit mainly include the exchange of sampling unit, the external expansion unit, display units, the control unit and other components, compact hardware, Programming easy, simple control. The device to real-time detection of network parameters, the system implemented tracking reactive compensation.
Key words: Reactive Power ComPensation,thyristor controlled reaetor(TCR),AT89S54 microcomPuter
