Intelligent Substation Relay Protection Debugging and Acceptance System Based on GOOSE Technology
Design an intelligent substation relay protection debugging and acceptance system based on GOOSE tech-nology to improve the debugging and acceptance effect.The system customizes the debugging environment and script loading module,generates voltage or current digital signals through distributed signal generators,converts them into analog signals,and applies them to relay protection devices through merging units to output GOOSE trip signals.The GOOSE communication module parses the signal and transmits it to the optical data conversion device to obtain the switch contact signal of the relay,which is then transmitted to the debugging control center through the high-speed digital output card.Using the DS evidence theory information fusion method,automatically debug and accept the mod-ule to test whether the device is abnormal.Finally,generate a debugging acceptance report.Experimental results have shown that the system can effectively complete the relay protection debugging and acceptance of different intelligent substations,and the communication effect is relatively good.
