The invention provides a method and system for testing an in-situ protection device. Different test groups are set in the test unit, and each protection sub-machine connected to the ring network included in the in-situ protection device is assigned to each test group, and Load corresponding test cases for each test group; establish communication with each protection sub-machine in each test group, and send test cases to each protection sub-machine to test each protection sub-machine. The invention performs message exchange on all sub-machines of the in-situ protection device at the same time, and realizes simultaneous testing on all sub-machines in the in-situ protection device. And when the number of protection sub-machines in different in-situ protection devices is not fixed due to different requirements, the test cases in the test unit do not need to be re-edited according to the number of different protection sub-machines, which greatly reduces the workload.
Description
A test method and system for in-situ protection device technical field The invention belongs to the automatic testing technical field of relay protection device, particularly a kind of in-situ protection device testing methods and systems. Background technique Relay protection device is an important part of the power system, it has a very important role in ensuring the safe operation of the system. effect. When the system fails, it can remove the faulty equipment and contribute to the safe operation of the system, but the protection of the relay The damage to the system caused by incorrect actions is enormous. Relay protection devices require reliability, selectivity, sensitivity and fast The unity of nature, in which reliability is the most important requirement of relay protection devices. [0003] The in-situ protection device is directly installed in the switch field or integrated with the primary equipment. Protective installation method, the operating envir...
