Modeling of Extra-high Voltage Magnetically Controlled Shunt Reactor

Abstract

From power system point of view, the multiple functions and application prospects of controllable shunt reactor in EHV and UHV power grid are analyzed;with 500kV magnetically controlled shunt reactor(MCSR) demonstration project in Jiangling converter station, China, the magnetic circuit structure and working principles of MCSR are analyzed, and the mathematic model of MCSR are deduced;on the basis of above, a new method of modeling complex magnetic circuit-magnetic circuit decomposition approach is proposed, and simulation model of MCSR is established.In order to verify the accuracy of the simulation model, the test results of 10 kV prototype and simulation results are compared, the experiments verify the accuracy of the simulation model.The proposed magnetic circuit decomposition approach is clear in principle, easy in modeling, precise in simulation result, applicable in engineering, suitable for power system electromagnetic transient calculation, and provides necessary simulation means for UHV and EHV MCSR analysis.
