摘要:

针对智能变电站继电保护运维操作需求及运维误操作的原因，提出了一种继电保护运维智能防误方法。该方法以主动式综合防误技术为基础，融合一次设备和二次设备的运行状态，建立覆盖变电站所有设备控制操作的主动安全机制，强制闭锁未通过防误规则判断的任一控制操作。以硬压板误投补救技术为补充，建立实时监视硬压板状态变化的风险预判体系，采取补救措施有效切除引起风险的因素。以装置检修隔离安措防误技术为辅助，实现装置检修一键隔离，并充分保障安全性和可靠性。采用装置就地操作防误技术，建立装置就地操作与监控后台综合交互防误机制，实现装置就地与监控后台操作防误的一致性。该方法在现场的应用取得了良好的防误效果，对继电保护运维有积极的作用。

Abstract:

Aiming at the smart substation relay protection maintenance demand and the reason of misoperation, a smart anti-misoperation method of relay protection maintenance is proposed. The method takes active combining anti-misoperation technology as a basis, which combines the running state of primary equipment and secondary equipment to build the active safety mechanism which covers all device operations of the substation, and rejects any operation which can’t pass the anti-misoperation rules. It takes hard strap misoperate remediation technology as a supplement, which builds the risk warning system to monitor the state of hard straps by real time, and starts remediation measures to remove the risk factor. It takes safety measures maintenance technology as an auxiliary, which isolates the maintenance device through one button with high security and reliability. It takes device local anti-misoperation technology to build interactive anti-misoperation mechanism between the local device operation and monitoring system, which makes the anti-misoperation consistency come true. This method obtains good effects in smart substation, which is helpful to relay protection maintenance.

Key words: relay protection maintenance active combining anti-misoperation hard strap misoperate remediation safety measures maintenance device local anti-misoperation
