The invention relates to an intelligent substation secondary equipment operation and maintenance object safety error prevention method and device, belonging to the comprehensive automatic technology field of intelligent substation in an electric power system. The method and apparatus of the invention firstly edits and generates a secondary operation and maintenance sequence ticket for the secondary equipment operation and maintenance object in need of operation and associates each operation step of the generated secondary operation and maintenance sequence ticket with relevant blocking logic. Then, the operation and maintenance state of the secondary equipment is online monitored based on relevant signal and state vector as well as on the each operation step of the generated secondary operation and maintenance sequence ticket for the secondary equipment. Finally, the error prevention blocking real time calibration is performed based on the associated error prevention blocking condition of the secondary equipment operation and maintenance object and the real time state of the associated equipment as well as through calculations under the logic conditions. For the above steps, it is possible to realize safety error prevention of secondary equipment operation and maintenance object, and the overall operation and maintenance process can be completed in a direct, visible and closed loop.
Description
technical field [0001] The invention relates to a safety error prevention method and device for secondary equipment operation and maintenance operation objects of intelligent substations, and belongs to the technical field of comprehensive automation of intelligent substations in electric power systems. Background technique [0002] With the development and improvement of smart grid technology, smart substations have gradually become the key to smart grid technology. The smart substation adopts a "three-layer two-network" architecture. The "three-layer" is the station control layer, the bay layer and the process layer. The process layer network, the secondary circuit uses optical fiber or network for communication, and uses industrial Ethernet technology to replace the traditional secondary wiring method to transmit analog and digital signals. Compared with conventional substation secondary equipment operation and maintenance operation objects, smart substation has the foll...
