Method for building intelligent substation relay protection cooperation simulation testing system

Abstract

The invention relates to a method for building an intelligent substation relay protection cooperation simulation testing system. Based on a Windows multithreading operating system of a PC, aiming at related requirements for IEC61850 communication and digitization protection testing, and through reasonably allocating task priority and dispatching and communication among the tasks, a certain type IED function produced by a manufacturer can be realized on the PC through leading-in a CID (configured IED description) document representing external characteristics of different manufacturers, and the mutual coordination, interlocking and shutting relations among the IED provided by different manufacturers in process layers and spacer layers of intelligent substations can be on-line detected without needing a real IED device and under the premise that the main wiring manner of different substations is adopted, so that consumption of manual labor and material resources can be greatly reduced; and the existing IED does not stop operating when the intelligent substation is expanded and rebuilt or the IED is replaced, thereby avoiding careless mistake and error during the disassembly, transportation and reinstallation processes of the IED device.

Description

technical field [0001] The invention relates to an electric power protection technology, in particular to an intelligent substation relay protection cooperative simulation test system. Background technique [0002] With the continuous improvement of energy security requirements, smart grid has emerged as a national strategy. The smart substation will gradually replace the traditional integrated automation system of the substation and become the basic element of the smart grid to complete its functions. IEC61850 is the most complete substation system and communication standard released by TC57 so far. The realization of intelligent substation based on IEC61850 standard will bring far-reaching influence and changes to the automatic operation and management of substations in my country. In recent years, with the promotion and application of the IEC61850 standard in China and the gradual deepening of the research on related technologies of smart substations, the pilot construct...

Problems solved by technology

If all the protective devices are tested jointly, it will consume a lot of manpower and material resources

If it is the expansion of the substation, it is necessary to stop the existing protection for testing, which will cause unnecessary power outages, and it is inevitable that there will be mistakes and errors during the disassembly, transportation and reinstallation of the protection device, which will seriously affect the safety of electricity use.
