Abstract:

研究了一种配电网电能质量实时监测分析与治理仿真系统,在准确、快速地检测和分析电能质量的基础上,进一步提出了合理的治理措施并进行了实时仿真分析。系统硬件主要包括由数字信号处理器、A/D采样电路及工控机组成的电能质量在线监测与分析设备;系统软件包括电能质量检测与分析、人机界面展现、支路选择与实时数据显示、电能质量治理仿真、历史数据查询等模块。采用复序列快速傅立叶变换(complexsequencefastFouriertransform,CSFFT)算法进行电能质量参数分析,并提出了一种新的双谐振注入式混合型有源滤波器(hybridactivepowerfilterwithdouble-resonanceinjectioncircuit,DIHAPF)的治理方案。广西某110kV变电站的应用效果证明了此方案的先进性和有效性。
