Research on phase locked synchronization in unified power flow controller
摘要
Abstract
The rapid and accurate phase and symmetrical components detection is essential for the control of Unified Power Flow Controller (UPFC). The novel phase locked loop (PLL) in this paper is based on double synchronous reference frames and uses decoupling to cancle out double frequency component. It uses small model platform of Matlab and UPFC to simulate the phase locked synchronization performance under the conditions of severe disturbances of voltage harmonic, three-phase asymmetric short circuit and frequency discontinuity, and compares it with the conventional phase locked loop based on Park transformation. The results of simulation and experimentation both verify the fact that the novel PLL can detect the phase fast and exactly, and has more flexibilty as the phase locked loop of UPFC.This work is supported by National High Technology Research and Development Program of China (863 Program).关键词
