摘　　要：介绍多直线遮挡器失步保护的原理,并以某电厂为例,介绍了对失步保护的整定算例的计算过程,并提供了一种实用的失步保护静态模拟测试方案(包括测试接线图、失步保护边界电阻定值和变压器电栓定值的测试,以及失步保护的滑极次数的测试)。The paper introduced the principle of out of step protection of multi-line shelter, and discussed the setting calculation process of out of step protection taken certain power plant as example. And a kind of practical scheme of testing for static simulation of out of step protection was offered including testing wiring diagram, testing for setting value of boundary resistance of out of step protection and setting value of transformer reactance, as well as the test of frequency of slipping pole of out of step protection.
