摘要:
GIS開關操作會産生特快速TEV,導致變電站二次系統的電磁兼容問題。爲了觀測和了解該特快速TEV的特性,研究了特快速TEV測量方法,建立了試驗電路和測量系統,觀測和分析了測量中電壓傳感器連線方式對測量准確度的影響,給出了特快速TEV測量的指導原則和推薦電路。TEV測量應避免在GIS殼體上直接連接大尺寸的導體,以避免對原有TEV的改變;電壓連接導線應盡量傳送參考零電位電壓,避免傳送特快速TEV,以避免電壓傳送引起TEV波形的畸變。
Abstract:
GIS may produce very fast transient enclosure voltage(TEV)in switching operation to cause electromagnetic compatibility problem in substation’s secondary system. In this study, a test circuit and a measurement system for the very fast TEV were developed, and the influence of the wiring connection of the TEV point, the reference zero potential point and the measurement device on the TEV measurement accuracy was analyzed. A guiding principle and a recommended circuit for the TEV measurement were proposed. It is suggested that: connecting a large size conductor on GIS enclosure should be avoided in TEV measurement to avoid making change of the original TEV; voltage connecting wire should transmit reference zero potential instead of TEV to the measurement device to avoid causing distortion of TEV waveform.
