基于数字锁相环的主被动复合反孤岛方法研究
Study on composite islanding detection method based on digital phase-locked loop
摘要
Abstract
Based on a kind of three-phase digital phase-locked loop which the voltage controlled oscillator is instead of frequency divider , this paper puts forward a new primary passive compound islanding-detection method .Including a new type of active phase shift protection method , a new type of over/under voltage protection based on the principle of phase-locked loop synchronous reference frame .Combined with the other two types of passive detection methods at the same time and all depends on the three-phase digital phase-locked loop .The composite detection method is featured with no detection blind area , less impact on the power quality , the detection speed meeting the requirements , and the structure is simple and easy to realize .The model building and simulation in the Matlab/Simulink verified the method can meet the design requirements and purpose .关键词
