基于MATLAB的供电系统多谐波源叠加方法的研究

Study on the Superposing Methods of Multi Harmonic Wave Source Based on the MATLAIB Power Supply System

针对供电系统中的多谐波源现象,可以考虑谐波叠加问题。在相应假设条件下,提出应用中心极限定理计算同次多谐波源的谐波电流矢量叠加。同时得到了该次谐波电流的概率统计特性。和Monte Carlo模拟相比较,论证了所提方法的合理性和可靠性。

Aiming at multi-harmonic wave source in power supply system, the wave-superposing problem should be considered. Under the corresponding suppositions, this paper puts forward to use the central limit theorem to compute the superposition of harmonic wave currents of multi-harmonic wave sources. At the same time, the characteristic of probability of harmonic wave current can be obtained. The rationality and reliability of this method can be demonstrated by comparing it with the Monte-Carlo simulation.
