| 摘 要： | 章在综述了开闭所保护现状后，引入面保护原理，结合现场总线网给出了在开闭所保护上应用的判据，以及在10kV实验室的试验结果。试验证明将面保护原理应用于开闭所的保护是成功的，当线路发生短路故障时，它可在0．3s内判断出故障是发生在某回出线上还是某段母线上，并可分别正确给出各进线断路器、出线断路器的动作出口。

| Abstract: | This paper surveyed the protections in switch substations, and introduced the area - protection principle. The criteria of area-protection based relay with field - bus - network applied in switch substation were given, and the laboratory tests of 10kV subsystem were shown. The test results indicate that the protection proposed is successful, which can make decision where short - circuit takes place at buses or load lines during 0.3s, and then feeder breakers or load breakers trip off. |
