zero-sequence component
解釋
零序分量-
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。 -
The protector makes the over - current value, zero - phase - sequence component, negative - phase - sequence and so on as protection criterions, in protection theory ; it makes atmel 8 - bit microprocessor at89c55wd as the core, with which the lattice lcd is linked, in hardware
該保護裝置在保護理論上，以檢測過電流幅值、零序電流為判據；在硬體實現上，以atmel單片機at89c55為核心，外接圖形點陣式液晶顯示器、觸摸式按鍵等外設。 -
When zero sequence or high secondary harmonic current component appear in the circuit, the total current in the shield is zero, no electromagnetic interference with outside
當線路出現零序或高次諧波電流分量時，屏蔽層內電流總和為零，不對外界產生電磁干擾。 -
It has the characteristics of fault component relays such as being immune to the load and the system operating mode and the zero sequence components required by the relay can he easily acquired and available for a long time
由於採用零序電量作為判斷依據，新方法具有受兩側電源角度的影響小，且受負荷、系統運行方式的因素影響小的特點。
