Power plant auxiliary power bus small-disturbance switching control system based on network command issuing

The invention provides a power plant auxiliary power bus small-disturbance switching control system based on network command issuing, the system is based on an IEC61850 communication protocol and is composed of a one-key switching device terminal, a communication network and a monitoring control logic, data exchange between a one-key switching device and a monitoring background is realized through an MMS service protocol, a tripping and closing control mode of'direct network tripping 'is adopted, and the power plant auxiliary power bus small-disturbance switching control system based on network command issuing is realized. The minimization of the disturbance quantity in the bus switching process is realized, and the safety of the switching process is improved. According to the control system, small-disturbance one-key switching control of the auxiliary power bus is achieved, operation is safe, simple and reliable, the monitoring side is provided with operation interfaces in one-to-one correspondence with the
