1.
To address the problem of zero sequence direction relay’s non-operating under the zero sequence voltage’s threshold, a new method of phase comparison is presented by using positive sequence voltage instead of zero sequence voltage.
针对上述问题,文中系统阐述了各种不对称接地故障下,系统各点故障前后正序电压的相位偏差、过渡电阻对各序分量相位的影响、正序与零序电压间最大相位偏差、送端与受端功角对该相位差的影响等,并据此提出了零压不够时采用正序电压代替零序电压进行比相的补充方案。
