摘要
基于链式逆变器的静止无功发生器(STATCOM)具有比基于变压器多重化逆变器的STATCOM更多的优点。文中介绍了50MVASTATCOM的主要作用及技术指标,给出了基于集成门木及换相晶闸管(IGCT)链式逆变器的主电路50MVASTATCOM的构成、基于谐波优化的脉宽调制(PWM)控制策略。装置的满载出厂试验采用等价额定工况运行试验,文中给出了等价额定工况运行试验的原理以及试验结果。试验结果表明,链节设计达到了链式STATCOM技术标准的要求。
Statcom based on chain inverter has more advantages than statcom based on inverter of multiple-transformer. The main technical indices of 50 mva statcom were introduced. The main circuit composition of 50 mva statcom based on igct chain inverter, and the strategy of pwm control based on harmonic optimization were given. The operating test of equivalent rated condition was adopted for fully loaded routine test of the installation, the principle and testing results of equivalent rated condition test were given in the paper. The testing result shows that the design of chain link has reached the technical requirements of chain statcom.
