双母双分、双母单分母线保护测试模型设计

Design of Bus Protection Test Model for Double-Bus Double-Segment Connection and Double-Bus Single-Segment Connection

双母线双分段和双母线单分段是220kV、110kV变电站的典型母线接线方式。分析两种接线方式母线保护装置动模测试项目的异同,设计了可同时兼容两种接线方式母线保护测试的典型测试模型。该模型也适用于两种接线方式母线保护装置同时进行测试试验,有助于缩短母线保护测试周期,提高测试效率。

The double-bus double-segment and the double-bus single-segment are typical bus connection modes in 220 kV and 110 kV substations. This paper analyzes the similarities and differences of dynamic model test items of bus protection devices with two connection modes, and designs a typical test model compatible with bus protection test of two connection modes The model is also suitable for bus protection devices with two connection modes to carry out tests at the same time, which helps to shorten the test cycle of bus protection and improve the test efficiency.
