智能变电站顺控技术工程实践

Project Practice of Sequential Control for 220 kV Caihong Smart Substation

摘要:

智能变电站是智能电网的重要基础和支撑，顺序控制是智能变电站的基本功能要求。由于智能变电站技术 仍处于发展阶段，当前使用顺控技术的变电站较少，实际运行管理经验较欠缺。以国网杭州供电公司 220 kV 彩虹智 能变电站为例，介绍了智能变电站对顺控技术的要求，分析了监控后台、顺控系统、操作票系统、五防系统之间的关系， 并以实际操作演示了顺控操作执行过程，最后指出了彩虹变电站顺控系统建设方面的不足，并提出了相应的建议。 对顺控技术的分析与实践对于智能变电站顺控系统建设有一定的借鉴意义，并可以为运行值班人员对智能变电站设 备的顺控操作提供一定参考。

Abstract:

The construction of smart substation has an important significance for the foundation of smart grid，and the sequential control is one of basic requirements for smart substation． The quantity of smart substations is low at present，and the sequential control technique is not widely used，so there lacks experiences in operation and management of sequential control for smart substation． Taking 220 kV Caihong smart substation for example，the requirements for sequential control technique in smart substation are introduced，and the relationship among monitoring system，sequential control system，operation order and mis － operation prevention system is analyzed． The process of sequential control is also demonstrated by practical operations． The deficiency of sequential control system in 220 kV Caihong smart substation is pointed out，and the corresponding suggestions are put forward． The analysis and practice of sequential control technique for Caihong smart substation provide a reference for the construction and manipulation of smart substations．
