hydro modulus
解釋
流量模數-
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。 -
