摘 要:以三相負(fù)載不對(duì)稱的電力系統(tǒng)為模型,介紹了電力系統(tǒng)傳統(tǒng)的補(bǔ)償方式,闡述了基于混沌差分算法的恒功率計(jì)算策略原理及算法實(shí)現(xiàn)過(guò)程,使用Matlab 編制了基于混沌差分恒功率計(jì)算法的仿真算法,分析了在給定功率條件下,電力系統(tǒng)三相不平衡在采用恒功率無(wú)功補(bǔ)償方式后的電流特性。并在差分進(jìn)化算法的基礎(chǔ)上,引入混沌優(yōu)化算法,得到改進(jìn)混沌差分算法,增強(qiáng)優(yōu)化搜索能力。仿真結(jié)果表明:此優(yōu)化算法可以快速而精準(zhǔn)地計(jì)算出最適合系統(tǒng)無(wú)功的補(bǔ)償方式,且所產(chǎn)生的誤差最小、系統(tǒng)魯棒性強(qiáng)。

Abstract: Taking the power system of three-phase asymmetry load as a model, this paper introduced the traditional compensation method for the power system, expounded the constant power calculation strategy principle and algorithm realization process based on chaotic difference algorithm and used Matlab to compile the simulation algorithm based on the chaotic difference constant power. This paper analyzed the current characteristics of the power system three-phase unbalance after adopting constant power reactive power compensation mode under given power conditions. On the basis of the differential evolution algorithm, this paper introduced the chaostic optimization algorithm to enhance the search capability. Simulation results show that this algorithm can quickly and accurately calculate the most suitable system reactive power compensation mode, the error is the least, and the system is robust.
Key words: asymmetry; reactive compensation; chaotic difference; constant power
