Abstract

The present application provides a communication testing method, device and system for a stability control device and a DC control protection device. This application first generates the DC control and protection device simulation command and the DC control and protection device simulation command according to the specified interface protocol and timing parameters, and then sends the DC control and protection device simulation command to the stable control device and the DC control and protection device based on the factory. The control device sends the simulation command of the stability control device to the DC control and protection device, so that the stability control device and the DC control and protection device respectively operate according to the received simulation commands, and then receives the feedback command generated after the operation, and passes the received feedback The command is compared with the standard feedback command, and the two-way communication test result between the stability control device and the DC control protection device can be determined according to the comparison result. It is not necessary to use RTDS to build a complete simulation of the DC control protection device and the stability control device, which solves the problem of existing The communication test between the stable control device and the DC control and protection device has the technical problems of cumbersome test process and low efficiency.

Description

technical field [0001] The present application relates to the technical field of power equipment testing, and in particular to a communication testing method, device and system for a stability control device and a DC control protection device. Background technique [0002] With the development of the DC transmission system towards the trend of large capacity and high voltage and the application of practical projects, it has an important impact on the safe and stable operation of the AC and DC power grid, and a corresponding security and stability control system is required. At present, the stability control device (full name is power system safety and stability control device stability control system) and DC control and protection device (full name is DC control and protection device) use digital optical fiber communication interface to exchange information. Stable information interaction is to realize the stable operation of the two One of the important factors, although th...
