Embodiment Construction
[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0019] Such as figure 1 As shown, it is a flow chart of a method for preventing erroneous power transmission of the present invention, a method for preventing erroneous power transmission, which associates the dispatch management OMS system with the power grid monitoring D5000 system, and the specific work includes the following steps:
[0020] (1) When the transmission line needs to be repaired, according to the number of required repair points, the dispatch management OMS system will handle more than one work ticket;
[0021] (2) The dispatch management OMS system sends the power transmission information of the maintenance line to the grid monitoring D5000 system, and the grid monitoring D5000 system marks the maintenance board corresponding to the above one or more work tickets on the corresponding line on the system screen;

The invention discloses a method for preventing erroneous power transmission, which relates to the technical field of power transmission. The invention associates the dispatch management OMS system with the power grid monitoring D5000 system. The dispatching management OMS system handles the corresponding work tickets, and the dispatching management OMS system transmits the information of all inspection points to the grid monitoring D5000 system, and the grid monitoring D5000 system marks the corresponding inspection boards on the corresponding lines according to the information of the inspection points; when a certain When the inspection point is overhauled, the dispatch management OMS system cancels the work ticket corresponding to the inspection point, and then the dispatch management OMS system transmits the inspection point completion information to the power grid monitoring D5000 system, and the power grid monitoring D5000 system automatically cancels and works The inspection card corresponding to the ticket; when the line that needs to be repaired in the grid monitoring D5000 system no longer has an inspection card, the line can be energized, and the design of this method can prevent the occurrence of wrong power transmission.
Description
technical field [0001] The invention relates to the technical field of power transmission, in particular to a method for preventing wrong power transmission. Background technique [0002] When the transmission line needs to be repaired, the controller needs to stop the power transmission operation, but usually a line needs to be repaired in multiple places, and each repair point needs to apply for a work ticket, so that there are multiple jobs for the same line that needs to be repaired In the case of tickets, in order to ensure safety, power can only be sent to the line after all work tickets are completed. [0003] At present, the dispatching and management OMS system is used to process work tickets, and the grid monitoring D5000 system is used for grid monitoring. One line handles multiple work tickets, but only one maintenance warning sign can be hung on the screen of the grid monitoring D5000 system, which cannot correspond to the number of work tickets. Check the wor...
