基于动态相量的LCC-HVDC输电系统等值技术评述
Overview of LCC-HVDC Transmission System Equivalent Technology Based on Dynamic Phasor
摘要
Abstract
Based on the AC bus at the receiving end of the inverter side converter station,the single end equivalence of the LCC-HVDC transmission system is of great significance for the optimal design of relay protection,stability control and DC control and protection.To obtain the high accuracy and real-time of calculation at the same time,the dynamic phasor model is used as an important way to realize the double terminal equivalence of LCC-HVDC transmission line at the expense of low simulation accuracy.However,there are still many problems in the single terminal equivalence of LCC-HVDC transmission system.To solve this problem,this paper analyzes the application value,requirements and difficulties of LCC-HVDC transmission system equivalence based on dynamic phasor,reviews the existing research status and existing problems from four factors in the equivalence calculation model,such as early trigger angle calculation,commutation overlap angle calculation,commutation failure discrimination and its influence on switching function and signal modulation,and puts forward follow-up research suggestions.关键词
