摘　　要：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(complex sequence fast Fourier transform,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(hybrid active power filter with double-resonance injection circuit,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。A simulation system of real-time power quality monitoring and harmonic suppression for distribution network is researched. On the basis of detecting and analyzing power quality rapidly and accurately, a rational harmonic suppression measure is given and related real-time simulative analysis is performed. The hardware for this simulation system is an on-line power quality monitoring and analysis device consisting of digital signal processor （DSP）, A/D sampling circuit and industrial personal computer （IPC）; the software of the simulation system includes such modes as power quality detection and analysis, man-machine interface, branch selection an＆real-time data display, harmonic suppression and historical data query. By use of complex sequence fast Fourier transform （CSFFT）, the power quality parameters are analyzed and a new harmonic suppression scheme using hybrid active power filter with double-resonance injection circuit （DIHAPF） is proposed. Practical results of applying the proposed simulation system to a certain 110 kV substation in the Guangxi Zhuang Autonomous Region, China show the proposed simulation system is advanced and feasible.
