中文摘要:

智能变电站测控装置采用单套配置，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、定值及软压板状态同步、模型及配置等价实现等关键技术，间隔虚拟测控单元使用跟实体测控装置相同的运行参数、虚端子联系表、联闭锁规则及ICD模型，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 smart 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 smart 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 respectively. By configuring cluster measurement and control devices, using key technologies such as measurement and control function virtualization, constant value and soft plate state synchronization, model and configuration equivalence realization, the interval virtual measurement and control unit uses the same operating parameters, virtual terminal contact table, blocking rules and ICD model, and the functional equivalence, model equivalence and configuration equivalence of the cluster measurement and control device is realized, which solves the redundant switching problem of the measurement and control function when the smart substation measurement and control device fails, and improves the reliability of the smart substation monitoring system. The validity and adaptability of the proposed scheme are verified through test verification and engineering application.
