摘　　要：传统变电站内顺控操作系统主要针对一次设备,不包含对二次保护硬压板的顺序控制,导致顺控工作并不能从根本上改变现有依靠人工逐项操作的工作模式。为此,文中设计了基于微电机遥控的继电保护顺控防误操作系统。设计了继电保护硬压板防误操作告警模块,通过硬压板分位触点的断开与闭合发出告警信息。在典型操作票操作逻辑的基础上,使用一键式微电机遥控防误操作模块支持调度远方程序操作,并通过地线解闭锁管理模块规范管理地线。设计一键式防误操作流程,利用循环冗余校验码分别检测发送端和接收端出现的误码,在顺控操作过程中实现防误操作。实验结果表明,该系统电压输出的上下波动幅度范围为-2.5~2.5 V,且输出波形与理想波形一致,具有良好的防误操作效果。The sequential control operating system in the traditional substation is mainly for the primary equipment,and does not include the sequential control of the hard platen for secondary protection.As a result,the sequential control cannot fundamentally change the existing working mode of relying on manual operation.Therefore,this paper designs a relay protection and anti⁃misoperation system based on micromotor remote control.An alarm module is designed to prevent misoperation of the relay protection hard pressure plate,and an alarm message is sent by opening and closing the dividing contact of the hard pressure plate.On the basis of the typical operation ticket operation logic,the remote control anti⁃misoperation module of one⁃key micro⁃motor is used to support the scheduling of remote program operation,and the ground wire is managed by the ground wire unlatching management module.The one⁃click anti⁃error operation process is designed,and the error codes of the sender and receiver are detected by the cyclic redundancy check code,so that the anti⁃error operation can be realized in the process of sequential control.The experimental results show that the fluctuation range of voltage output of the system is-2.5~2.5 V,and the output waveform is consistent with the ideal waveform,which has a good anti⁃misoperation effect.
