| Abstract: | The shortcomings of existing latching system are analyzed and the latching system of micro-computer antimisoperation network based on PLC is expoanded.Several S7-200 computers are utilized in this system to perform the acquisition of electrical signals and to execute the function of operation latching for controlling the local electrical apparatus in substation.The master computer is used as the centre of control system and synthetic judgment,and is connected with PLC by RS-485 communication line to perform real-time monitoring on local apparatus.The practical case of this system shows that the demand of grid operation and anti-misoperation of substation is in conformity. |
