摘要
电网运行方式变化时,需要同步调整继电保护的运行方式,否则保护存在误动或者拒动的可能性。提出了基于通用保护模型的保护操作规则库的设计,分析了保护操作校核系统的体系结构和功能模块,重点阐述了一次设备运行态判别、保护操作校核服务进程等关键模块的实现,并介绍了系统的测试情况。该系统利用电网的实时运行状态和继电保护的运行信息,校核继电保护的操作结果,判断调整后的保护运行方式是否满足电网运行的要求。
When the power grid operation mode is changed,the relay operation mode should be adjusted synchronously,otherwise the relay may malfunction or reject action. The relay operation rule base design based on general protection model is proposed. The structure and function module of relay operation verification system are analyzed. The implementation of key modules such as equipment operation state identification and relay operation verification process is elaborated. The system test result is introduced. Using the power grid real-time operation status and relay operation information,the system verifies the relay operation results and determines whether the adjusted relay operation mode meets the requirements of power grid operation.
