zero sequence system的意思|示意

Used together with SD-LJD (LXK) series ZCT and executing relay to form a complete zero sequence (ground) protection system.

配合SD - LJD (LXK)系类零序电流互感器和动作继电器即组成完整的零序(接地)保护系统。

So it is necessary to find some ways for the fault location detection. In the phase-to-earth fault power system, the value of zero-sequence impedance is directly related to the earth conductivity.

这样就降低了供电可靠性，故找出一种新思路使其能更准确有效地判断故障点具有重要意义。

The phase comparison error is the primary factor leading to mistaken action in the selective leakage protective system of underground LV networks based on zero sequence current direction.

在基于零序电流方向原理的矿井低压电网选择性漏电保护中，比相误差是导致保护误动的主要因素。

The zero-sequence measurement current's distribution in the automatic arc-suppressing coil earthed power system is analyzed.

It shows that DVR will inject small zero sequence component into the power system during compensation control even if there is no zero sequence circuit. This will influence the voltage on system side.

分析表明，即使系统不存在零序回路，DVR都会在补偿控制中向系统注入微小的零序分量，该零序分量会对无零序回路系统侧电压造成不良影响。

The zero-sequence parameter of transmission lines especially of transmission lines with mutual inductances is of great important in the relay protection setting calculation of power system.

输电线路的零序参数尤其是多回互感线路的零序参数是电力系统继电保护整定计算需要的重要参数，所以其准确测量具有重要意义。
