| Abstract: | The requirements,handling scheme and key techniques of misoperation-preventive locking system for the supervisory control system reform of a 500 kV substation are presented. The reformed misoperation -preventive locking system has the monitoring logic locking,microcomputer-based five-preventive locking, electrical locking and mechanical grounding switch locking. The measuring and control equipment is installed in each cell to control the supervised breakers,switches and grounding switches and measure the relative currents and voltages. The locking condition,form and means for the repair of damaged original locking are discussed. The handling scheme is implemented effectively. |
