摘要
针对传统响应时间检测方法存在基准时刻不统一、依赖间接测量量的问题,提出了一种基于实际触发角检测的晶闸管控制电抗器(TCR)动态响应时间评估方法。依据过零切除固定电容器组产生阶跃参考量统一基准时刻,通过TCR实际触发角与下限值的比较确定响应时刻,进而直接评估响应时间。实验结果表明,该方法可有效应用于大容量TCR型无功补偿装置动态响应性能分析、评价。
Abstract
Dynamic response time is a key index of thyristor controlled reactor(TCR) type static var compensator(SVC) dynamic performance. Aiming to solve traditional detection problems of no unified datum time and overdependence on indirect measurement, assessment method of TCR dynamic response time based on real firing angle detection is proposed. According to a step reference signal trip generated fixed capacitor(FC) zero-crossing trip, datum time is unified. Then the response time is determined by comparing TCR real firing angle with lower limit value. The experimental result shows that this method can be effectively applied to analyse and evaluate dynamic response performance of large capacity TCR type SVC.
