摘要
针对高压系统中CVT不能应用于谐波测量而成为电能质量监测的技术难题,提出了一种基于电容分压器的高压系统谐波测量的应用方案,并对电容分压器误差进行了分析,以110kV电容分压器为例进行了软件仿真计算和试验测试。结果表明,该方案有效可行。
As the capacitive voltage transformer （CVT） in high voltage system can not be used to measure harmonics, making the harmonic measurement of high voltage system becomes a technical problem in power quality monitoring. This paper proposes a new application program on harmonic measuring of high voltage system based on capacitive voltage divid- ers. The errors of capacitive voltage divider are comprehensively analyzed. Taking ll0kV capacitive voltage dividers for an example, software simulation and experimental test are carried out. The results show that the program is effective and feasible.
