Test platform for wide-area joint debugging of interstation stable control device and implementation method of test platform

Abstract

The invention provides a test platform for a wide-area joint debugging of interstation stable control device. The test platform is matched with a master station stable control device and a plurality of sub-station stable control devices interconnected with the master station stable control device in a wide-area way. The test platform comprises a test management host, a master station and a plurality of sub-station protocol transfer devices, wherein the test management host communicates with the master station stable control device by a master station protocol transfer device and is further interconnected with each sub-station protocol transfer device in a wide-area way by the master station protocol transfer device according to another data communication network, each sub-station protocoltransfer device is directly connected with the corresponding sub-station stable control device, and the test management host is used for simultaneously issuing a test parameter to the master station and each sub-station protocol transfer device and receiving action results of the master station and each sub-station stable control device fed back by the master station and each sub-station protocoltransfer device to judge whether performance between the master station stable control device and each sub-station stable control device is qualified or not. According to the test platform provided bythe invention, the problem of automatic test for wide-area joint debugging of the interstation stable control device can be solved in site, so that the site working efficiency and the maintenance level are improved.

Description

technical field [0001] The invention relates to the technical field of electric power safety and stability control, in particular to a test platform for wide-area joint debugging of inter-station stability control devices and an implementation method thereof. Background technique [0002] The safety and stability control system (hereinafter referred to as the stability control system) is a system composed of two or more safety and stability control devices (hereinafter referred to as the stability control device) connected through communication equipment to achieve the stability of the regional or larger power system. Control, take measures such as machine cutting and load shedding to ensure the safe and stable operation of the power system. With the gradual realization of inter-regional interconnection and power market, the grid structure is becoming more and more complex, the operation mode of the power system is flexible and changeable, and the stability problem (especial...

Problems solved by technology

[0004] At present, the testing technology of the stability control system is still in its infancy and cannot meet the actual application requirements.

Although the relay protection tester is the most commonly used test method at present, the ordinary relay protection tester can only output a limited set or two sets of voltage and current, and generally does not have the ability to output synchronously by multiple testers. To realize the automatic test of the wide-area joint debugging of the stability control device between stations, it is often necessary to use the method of repeated confirmation by telephone, which seriously affects the debugging efficiency
