  1. To resolve the situation that the sensitivity of present ground fault protection schemes is low for the large - sized hydro - generators, a kind of protection scheme based on the fault component of third - harmonic voltage and two kinds of protection scheme based on the fault component of zero - sequence voltage at the terminals and neutral are developed, and they can obtain higher sensitivity and reliability and provide 100 % protection for the stator windings. the influence of noise on the stator ground fault protection based on the local modulus maximum of wavelet transform is analyzed

    針對目前大型水輪發電機定子繞組單相接地保護靈敏度偏低的問題，通過分析單相接地故障后機端和中性點零序電壓的變化特點，提出了一種基於機端和中性點三次諧波電壓故障分量和兩種基於機端和中性點零序電壓故障分量的高靈敏度、高可靠性保護方案，並實現定子繞組的100 %保護。
  2. 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，並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。
  3. This paper discusses the size of transient zero current and the method of analyzing it. numeral simulation shows the feasibility of it. negative current at fault line is differ distinctly from non - fault line
