Research on All-pass Filter Based Control Strategy for Single-phase Static Var Compensator
摘要
Abstract
For the single-phase static var compensato(r SVC),pq transformation is widely used for detecting the magnitude of the reactive current. Constructing the virtual component which is orthogonal to the real load current is the key for pq transformation. Therefore,the all-pass filter based control strategy for single-phase static var compensator was proposed. In the proposed method,the all-pass filter was used to move 90 degree of the phase of the load current without change of the amplitude. Thereby,the virtual component which was orthogonal to the real load current was constructed. Finally,the simulation model of the all-pass filter based single-phase SVC was built in PLECS platform and the experimental results confirm the validity and feasibility of the proposed strategy.关键词
