Single-phase Reactive Rapid Detection Method Based on the Instantaneous Reactive Theory

The traditional reactive power calculation method according to traditional definition is difficult to meet the request of the dynamic reactive power compensation system controller in rapid response,therefore this paper uses instantaneous reactive theory to achieve the calculation of reactive power and detection in the dynamic reactive power compensation system controller.The text analyzes the single-phase instantaneous reactive power theory of principleo,ffers the detection method of ita,nd indicates the shortage of the method and offers the improvement program.It actualizes the detection of the single-phase reactive power in dynamic reactive power compensation system controller through the simulation.The simulation results show that the algorithm can quickly and effectively detect the single-phase reactive power,and the improvement program can effectively reduce the error caused by harmonics.
