In view of the lack of anti-misoperation technology of secondary devices in the dispatching and control integration operation mode of smart grid, this paper proposes and realizes a anti-misoperation technology of secondary devices based on the master and substation cooperation. Through the expansion of secondary devices anti-misoperation application service data unit (ASDU) based on IEC 104 communication protocol, the integration of control and anti-misoperation graph module is established to realize the maintenance of anti-misoperation information source end and logical consistency mutual check of anti-misoperation master substation. This paper systematically 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, station and station, designs the anti-misoperation algorithm of secondary device based on expert knowledge base, and realizes the anti-misoperation locking function of 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 operation risk control ability, and ensure the safety of remote operation of power grid devices.
