摘要:

针对智能电网“调控一体化”运行模式缺少二次设备操作防误技术手段问题,提出并实现一种基于防误主子站协同的二次设备防误技术。通过扩展基于IEC 104通信规约的二次设备防误应用服务数据单元(ASDU),建立调控与防误图模一体化,实现防误主子站的防误信息源端维护和逻辑一致性互校核。文中提出二次设备防误规则,建立一次设备与二次设备、二次设备与二次设备、站与站之间的防误逻辑,设计基于专家知识库的二次设备防误算法,实现一、二次设备远方操作的防误闭锁功能。现场实践表明,二次设备防误技术可提升设备状态感知能力和远方误操作风险管控能力,保障电网设备远方操作的安全性。

Abstract:

In view of the lack of anti-misoperation technology of secondary devices for the dispatching and control integrated operation mode of smart grid, this paper proposes and realizes an anti-misoperation technology of secondary devices based on the cooperation between master- and sub-station. Through the expansion of anti-misoperation application service data unit (ASDU) of secondary devices based on IEC 104 communication protocol, the integration of graph and model for control and anti-misoperation is established to realize the source end maintenance of anti-misoperation information and logical consistency mutual check of anti-misoperation master- and sub-station. This paper puts forward the anti-misoperation rules of secondary devices, establishes the anti-misoperation logic between primary device and secondary device, secondary device and secondary device, and station and station, designs the anti-misoperation algorithm of secondary device based on expert knowledge base, and realizes the anti-misoperation locking function for remote operation of primary and secondary devices. The field practice shows that the anti-misoperation technology of secondary devices can improve the devices state perception ability and remote misoperation risk control ability, and ensure the safety for remote operation of power grid devices.
