Description

technical field [0001] The invention relates to the field of testing of intelligent substations, in particular to a total-station intelligent terminal simulation device of an intelligent substation. Background technique [0002] The intelligent terminal in the intelligent substation realizes the intelligence of primary equipment, and is the most critical equipment in the transmission link of the circuit breaker, isolating switch, and grounding switch of the intelligent substation. The intelligent terminal receives the control command of the protection, measurement and control device, and its output is used as the input of the switchgear actuator; at the same time, the intelligent terminal receives the switchgear position signal contact and converts it into a digital GOOSE message, which is used as a means for the protection, measurement and control and other IED equipment to obtain the switch position. source, realize the organic integration of primary equipment and IEC61850...

AI Technical Summary

Problems solved by technology

The smart substation practical training system is responsible for the tasks of smart substation new technology and debugging technology training. Most of the secondary system equipment such as protection and measurement and control devices are configured according to typical smart substations to simulate the operation and function debugging of smart substations. Generally, smart terminals are used. Or simulate the circuit breaker to realize the simulation and message transmission of the switchgear position, but there are still problems of complex switch position simulation wiring and equipment investment. If a whole station intelligent terminal simulation device can be used, it can save a lot of intelligent terminal investment, and there is no Wiring complex issues

[0004] In addition, when testing the anti-misoperation locking logic of smart substations, the on-site pull-on switch is generally used to change the position of the switchgear to verify the five-proof logic. In the locking logic, there are many combinations of switch positions of the switchgear, and the test workload is quite large. In the actual test, Most of the selective spot checks of switch combinations to verify the anti-mislocking logic cannot fully reflect the possible hidden dangers of the anti-mis-locking logic, and the frequent pull and close of the switch equipment also has a certain impact on the life of the switch equipment.

[0005] At present, with the development of smart grid, it is necessary to gradually increase the intelligence of primary equipment. Intelligent components such as intelligent terminals and merging units tend to be integrated into primary equipment. The unit test and system test are carried out in cooperation with protection, measurement and control, which brings huge challenges to the unit debugging and system joint debugging of protection, measurement and control and other secondary systems
