中文摘要:
      智能变电站测控装置仍采用单套配置,存在单点故障导致测控功能失效的隐患,无法完全适应智能变电站无人值守的要求。针对“单间隔+集群测控”、“双套集群测控”两种配置模式分别提出了相应的测控功能冗余切换方案。通过配置集群测控装置,采用测控功能虚拟化思想、定值及软压板状态同步、模型及配置等价实现等关键技术,实现了集群测控装置的功能等价、模型等价及配置等价,解决了智慧变电站测控装置故障时测控功能的冗余切换问题,提升了智慧变电站监控系统的可靠性。通过试验验证和工程应用,验证了方案的有效性和适应性。
英文摘要:
      The intelligent substation measurement and control device still adopts a single set of configuration, and there is a hidden danger that a single point of failure causes the measurement and control function to fail, and it cannot fully meet the requirements of unattended intelligent substations. For the two configuration modes of "single interval + cluster measurement and control" and "double sets of cluster measurement and control", corresponding redundant switching schemes for measurement and control functions are proposed.By configuring the cluster measurement and control device, adopting key technologies such as measurement and control function virtualization idea, fixed value and soft plate state synchronization, model and configuration equivalence realization, the device can run multiple interval virtual measurement and control units at the same time, realizing the functions of the cluster measurement and control device, etc. Cost, model equivalence and configuration equivalence solve the problem of redundant switching of measurement and control functions when the measurement and control device of the smart substation fails, and improve the reliability of the monitoring system of the smart substation.Through test verification and engineering application, the validity and adaptability of the scheme are verified.
