摘　　要：分析了集中式和分布式变电站程序化控制实现方案的优缺点,提出了一种不依赖于站级网络通信协议、以间隔层智能电子设备(IED)为核心的分布式变电站程序化控制实现方案,操作票的存储、执行及操作逻辑的判断均在IED中实现,程序化控制过程中需要操作其他IED则请求站控层设备执行。该程序化控制方案已在CSC-2000变电站自动化系统中实现。该方案既适用于站级网络协议为IEC 61850等国际标准的变电站自动化系统,也适用于站级网络协议为以太网IEC 60870-5-103协议、CSC-2000协议等企业标准的变电站自动化系统,尤其适合在IEC 61850标准还没有完全普及的过渡时期采用。An analysis is made of the advantages and disadvantages of centralized and distributed sequence control schemes in the substation automation system. A new scheme for implementing distributed sequence control is presented that is independent of the protocol between the station level, and bay level with the bay level IED as the core and the storage and execution of the operation order sheet as well as the judgment of the operation logic all implemented by the IED. In the process of sequence control, when other inter-related IED＇s are to be operated, request should be made to a device on the station level for execution. The process has been implemented in CSC-2000 substation automation system. The scheme is applicable to the international criteria with protocol between station level and bay level IEC 61,850 as well as enterprise criteria with Ether IEC 60870-5-103, CSC-2000 etc. In particular, it is a good solution for applications in the transitional period when IEC 61850 is not yet very popular.
