Embodiment Construction
[0019] The method for remote confirmation of the remote control operation of the substation proposed by the present invention, the structural diagram of the system used is as follows figure 1 As shown, the method includes the following steps:
[0020] (1) Set up a video surveillance system, and install the cameras in the video surveillance system in the substation;
[0021] (2) Establish the mapping relationship between each switch switch of the substation and the video monitoring image of the camera, and store the mapping relationship in the database of the above video monitoring system. The opening and closing state images of the head, opening and closing indicator signs and switch cabinet indicator lights;
[0022] (3) The dispatcher of the control center of the electric power bureau sends a remote operation pre-order to the switch switch and the video monitoring system at the same time through the substation integrated automation system;
[0023] (4) The video monitoring...

The invention relates to a method for remotely confirming the remote-control operation of a transformer station, and belongs to the technical field of video monitoring and transformer station automation. The method comprises the following steps: firstly, establishing a mapping relation between a switch breaker of the transformer station and a video monitoring image of a camera; after receiving a preparatory remote-control operation command via a video monitoring system, obtaining the video monitoring image of the switch breaker corresponding to the preparatory remote-control operation command according to the mapping relation; confirming the power-on / power-off state of the switch breaker by analyzing the video monitoring image; comparing the power-on / power-off state with the preparatory operation command via scheduling personnel; if ensuring that the switch breaker is in a power-on / power-off state, sending a formal remote operation command to the switch breaker and the video monitoring system; and then repeating the processes above by serving the formal operation command as the preparatory operation command, so as to confirm whether the remote-control operation is succeeded. The method is high in automation degree, greatly improves the working efficiency; and the method is high in reliability for confirming the remote operation, and guarantees the working reliability of the transformer station. In addition, adopted equipment is simple. As a result, the method can be applied widely.
Description
technical field [0001] The invention relates to a method for remotely confirming remote control operations of substations, in particular to a method for remotely confirming remote control operations of substations based on video image analysis technology, and belongs to the technical fields of video monitoring and substation automation. Background technique [0002] The unattended operation of substations is the requirement of the "big operation" mode in the "three sets and five majors" of the State Grid Corporation of China, and it is also an inevitable trend in the development of power grid dispatching automation. The remote control function of the control center is the first necessary technical condition to realize "unattended". The modern substation integrated automation system has basically realized the remote control operation of the switch switch in the control center. However, in the process of remote control operation, due to safety considerations, it is necessary ...
