摘 要:介紹了傳統(tǒng)配電網(wǎng)三相不平衡問題的研究現(xiàn)狀。闡述了不同控制算法的適用條件及其各自的優(yōu)缺點(diǎn),對比分析了現(xiàn)有治理措施的實(shí)用性、可靠性和經(jīng)濟(jì)性;給出了未來環(huán)境下配電網(wǎng)三相不平衡治理的新思路,即不再利用傳統(tǒng)的負(fù)荷投切或是附加補(bǔ)償裝置,而是通過控制電動汽車和家用儲能設(shè)備的有序充放電,并通過優(yōu)化調(diào)度方案便可實(shí)現(xiàn)系統(tǒng)的三相不平衡治理。
關(guān)鍵詞:配電網(wǎng);三相不平衡;治理措施;儲能;電動汽車

Abstract: Introduction was made to the research status of three-phase unbalance problems in traditional distribution network. This paper expounds the application conditions and their relative merits of different control algorithms, contrastively analyzed the practicability, reliability and economy of existing control measures and gave the new idea of three-phase unbalance control measure of distribution network under the future conditions, that the traditional load switching would no longer be used or compensation device would be added, but the discharge of electric vehicles would be controlled, as well as the domestic energy storage equipment, the regulation scheme was adopted to realize three-phase unbalance administration.
Key words: distribution network; three-phase unbalance; control measure; energy storage; electric vehicle
