摘要
为提高电能质量,对电能质量实时监测系统和治理方法进行深入分析,设计了基于双DSP结构的电能质量实时监测系统的硬件电路和软件.采用快速傅里叶算法进行了电能质量分析,通过三相瞬时无功d-q检测方法实现了对谐波的治理并进行了仿真试验.仿真结果表明:所用方法能够有效滤除谐波,大幅提高了电能质量.
In order to improve power quality,real-time monitoring system of power quality and management methods were studied deeply in this paper.The hardware and software of it are designed based on double DSP structure.Power quality is analyzed by using the fast Fourier algorithm,on the basis of detecting and analyzing power quality rapidly and accurately.The harmonic managements of Power grid are realized through the method of Three-phase instantaneous reactive power d-q detection,the simulation experiment is done.The method used can effectively filter out harmonics and greatly improve the power quality.
