The utility model discloses an intelligent substation closed loop test system based on GOOSE network, this system are that it contains based on the TEST mode of IEC61850 standard: intelligent substation is connected to the analytic module of SCD, is surveyed protection system's anticipated response according to intelligent substation's SCD file generation, test control module connects the GOOSE network for send the test instruction, await measuring protection device according to using of forming of the virtual terminal relation of connection descriptor of intelligent substation SCD file and asthe protection system that is surveyed of core, connect the GOOSE network, produce the test response under the excitation of test instruction, analytic module of SCD and GOOSE network are connected to the test evaluation module for carry out the comparison to anticipated response and test response. Its advantage is: SCD has reflected the related relation of intelligent substation secondary system's signal, may produce automatically based on SCD and verify the related relation of secondary system, utilizes IEC61850 detection mode to realize closed loop test, can improve integration testing, on-the -spot commissioning tests and maintenance repair efficiency of software testing and exactness greatly.
