摘要
变电站综自系统不断普及,无人值班及集控所运行模式逐步建立,为了确保运行人员及时掌握第一手信息,必须强化信号管理。目前变电站自动化系统信号管理工作还不完善,因信号合并不适当、运行监控不到位等原因导致保护装置误动、断路器跳闸的事故已有发生。通过对事故案例的研究和分析,认为变电站自动化系统信号管理应明确各部门管理职责,采用标准化工作流程,才能避免出现管理死区,并介绍了采用的变电站自动化系统信号标准化管理技术和模式。
Substation automation system is developed, operation model of unattended and centralized control substation is created, and data size of signal is tremendous, but signal manage job is not perfect. Some accidents happened because of wrong signal merge method and careless monitor, such as protective devices wrong action or circuit breaker wrong trip. Signal of substation automation system must be indicated with correct classification and merge method, which can help operation workers to know the correct information. Dead manage space can be avoided if we adopt standardized job flow and definite duty.Technique and manage model about signal standard classification and merge manage of substation automation system are discussed in this paper.
