摘要
小浪底—西霞院线路发生AN单相接地时,WXH-803光纤差动保护出现拒动的情况,从保护原理和实际接线入手,分析出引起光纤差动保护拒动的原因是TA回路设计及施工的错误,并提出了整改措施。
WXH-803 optical fiber differential protection rejected to act when AN single-phase grounding of the Xiaolangdi-to-Xixiayuan line occurred. For this reason, this paper, on the basis of protection theory and practical wiring, analyzes the reason why the optical fiber differential protection rejected to act, and concludes that it is the mistake of design and construction of TA circuit, then puts forward the remedial measures.
