Research On Distributed Stability Control Device Strategy Testing System

As the power grid structure of our country is still not enough strong, installing the stability control device is the main means to operating the power system stably and securely. This dissertation researches the structure of distributed stability control device and the structure of the strategy table especially. Although the testing system of Microcomputer-based Protection device has been coming into maturity, testing system of distributed stability control device is just in the beginning nowadays. To resolve the problem of test the strategy table, the new testing scheme based on the field bus is presented. This scheme could test all the strategy of the device. The paper presents a hardware scheme and a software scheme of the testing system to detect the correctness of strategy.
