Research on Instant Reactive Power Theory Harmonic Waves and Idle Current Test Simulation

随着电力系统发展,对无功功率和谐波进行快速、动态补偿的需求越来越大,进行无功补偿和谐波抑制,实时、准确的测量和分析是至关重要的。因此要能准确、快速地从畸变的负载电流和电压中检测无功和各次谐波,就得采取适当的快速检测无功的方法。基于瞬时无功功率理论检测方法的成功应用,能较好地解决谐波电流和无功电流检测问题。

With the development of the electrical power system, the more demand of faster and dynamic compensation for reactive power and harmonic waves is more and more. It is key to measure in time and accurately for restraining idle work compensation and restraining harmonic waves. Therefore, the proper method is adopted to test the idle work quickly, which is from the distortion load current and the voltage of the idle work and various sub-harmonics. Based on the successful application of the instant reactive power theory examination method, it can solve the problem of testing harmonic current and the idle current examination.
