摘要
研究了10 kV电网中性点经ZnO非线性电阻接地运行的新方式,通过分析ZnO非线性电阻的U-I特性,针对非线性电阻的通流能力,对电网继电保护的配合和通讯干扰等问题进行了研究和探讨。
The 10 kV network neutral grounding by nonlinear resistance as a new neutral grounding mode for power system is brought forward. By analyzing the Volt Amp. characteristics and the passing current ability of ZnO nonlinear resistance grounding, the relay protection and interference over communication are discussed.
