From the perspective of minimum transmission losses , an instantaneous reactive power theory for systems with any number of phases and with or without neutral line is developed . under the new definition , each quantity has its own physical meaning , and the zero sequence current can be decomposed into active and reactive components . furthermore , a generalized compensation method for zero sequence current is developed 從輸電損耗最小的角度出發,提出了任意相無中性線或有中性線系統的瞬時無功功率理論,在新的理論下,每個量都有清晰的物理意義,且能分解出零序電流的有功分量和無功分量,并給出了通用的零序電流補償方法,揭示了瞬時無功功率理論與傳統平均意義下的無功功率理論的聯系及本質區別,從而為研究hvdc - vsc及各種facts裝置的無功功率控制奠定了理論基礎。
