Research Of Improving The Characters Of Magnetic Controllable Reactor

As a new-type, reliable, practical FACTs equipment, the appearance of magnetic controllable reactor provide a new technical method for EHV and UHV in the field of voltage control and reactive power regulation. It can make dynamic voltage stability, realize dynamic reactive power continuous adjustment, improve the safty and stability operation level of power system, suppress secondary arc current, reduce recovery voltage, improve the success rate of reclosing, and also have good economic and social benefits.In this paper, firstly, the basic theories, operation characteristics and simulation model of controllable reactor are studied completely through the National Natural Science Foundation project (50777019). Secondly, due to the harmonic fault of magnetic controllabe reactor, the theory of suppress harmonic by the shift-phase reactor is picked up, and theoretical derivation, simulation analysis, experimental verification are all done. The results show that this method can suppress the harmonic current efficiently. At the end, considering the shortage that the response time is too long, the theory and simulation of high speed excitation of magnetic controllable reactor is also discussed.The result prove that it can increase the response speed of magnetic controllable reactor, satisfied the project needs.
