结合廊坊电网调度自动化系统实际情况,在自动化主站系统中加入闭锁遥控执行的程序,在保证变电站遥控二次回路正常的情况下,应用此程序对已运行变电站的设备进行遥控测试。经过近三年的实际应用,证明此方法确实可以有效避免误遥控事故的发生,减少停电损失,减轻维护人员工作强度,保障人身安全和电力系统设备稳定运行。 Combined with the actual situation of Langfang grid dispatching automation system, the program of closed-loop remote control is added to the automation master station system. Under the circumstance of ensuring the normal secondary circuit of substation remote control, this program is used to test the remote substation equipment. After nearly three years of practical application, this method has proved that this method can effectively avoid the occurrence of accidental remote control accidents, reduce power loss, reduce maintenance work intensity, and ensure personal safety and stable operation of power system equipment.
