Problems solved by technology
Due to the construction of a large centralized control system in recent years, an EMS system needs to generate a lot of plant and station wiring diagrams and interval wiring diagrams, the number of which is very large, and the previous plant and station wiring diagrams and interval wiring diagrams cannot automatically achieve graphics The safety verification function can only rely on manually checking whether the equipment (circuit breaker, switch) on the graphic belongs to the factory and the interval. The checking work is very cumbersome and very error-prone. These errors include: not belonging to the factory station of the graphic The switchgear that does not belong to this bay is defined on this graph; the switchgear that does not belong to this bay is defined on this bay; the bay that does not belong to this plant station is defined to this plant station, etc. Misoperation will occur when some wrong switches are remotely controlled, causing an equipment and power grid accident, causing loss of corporate property or injury to personnel

Embodiment Construction
[0017] Embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0018] A multi-intelligent graph safety verification method is to use the information contained in the graph file to carry out safety verification on all the connected library devices of the graph on the grid monitoring center. Such as figure 1 As shown, the safety verification method includes the following steps:
[0019] 1. The power grid monitoring center reads the graphic file to obtain the information of the plant to which the graphic belongs
[0020] Since the graphic file includes two types of plant and station wiring diagrams and interval wiring diagrams, there are two methods to obtain the plant information through the graphic file: the first method is to obtain by reading the plant and station wiring diagram, because the plant and station wiring diagram includes Therefore, by reading the wiring diagram of the factory and station, th...

The invention relates to a method for safely verifying multiple intelligent graphics, which comprises the following steps: (1) reading a graphic file to obtain plant information which the picture belongs to; (2) analyzing the graphic file to obtain plant information which all alliance library equipment primitives belong to; and (3) comparing the plant information which the graphics belong to and the plant information which all equipment primitives belong to one by one; if the plant information which the equipment primitives belong to and the plant information which the graphics belong to are not consistent, providing error prompting information for a user to modify the plant information; after the user modifies the plant information, carrying out the step again; and otherwise, if the plant information which all the equipment primitives belong to and the plant information which the graphics belong to are consistent, completing the verifying function of the alliance library equipment primitives. The safe verifying method realizes the function of automatically and safely checking the graphics, can effectively reduce the error of the library alliance of the equipment graphics, improve the working efficiency, reduce the error and ensure the normal operation of a monitoring system.
Description
technical field [0001] The invention belongs to the field of power grid control, in particular to a method for safety verification of multiple intelligent graphics. Background technique [0002] With the continuous expansion of the power grid scale and the continuous improvement of the level of power automation, the control system of the power grid in various regions adopts the control mode of the control center more and more. The control center is usually undertaken by a dispatch center or multiple centralized control centers, which are responsible for monitoring and operating the operation status of each substation in the regional power grid to achieve centralized control of the regional power grid. Due to the continuous improvement of station-side automation level, especially the continuous popularization of unattended integrated automation substations, more and more operational tasks need to be completed directly in the grid monitoring center by remote control. At prese...
