Embodiment Construction
[0014] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0015] There are various main wiring methods of substations, and here, the main wiring methods that do not contain busbars are firstly excluded. This is because substations without busbars basically only exist in low-voltage power grids. In substations with high voltage levels of 110kV and above, busbars are basically used as nodes for importing and exporting electric energy. In substations with busbars, according to different busbar wiring methods, it can be divided into single busbar wiring, single busbar section wiring, single busbar with bypass wiring, single busbar section with bypass wiring, double busbar wiring, and double busbar substation. Segment wiring, double busbar with bypass wiring, double busbar segmental with bypass wiring, 3 / 2 wiring, 3 / 2 wiring with segmentation, etc. Analyzing the main wiring methods of these substation...

The invention provides an automatic identification method for a main wiring diagram of a plant station, and the method comprises the steps of taking three types of basic bus wirings as the center to establish the groups to automatically identify the main wiring mode of the plant station, wherein the three types of basic bus wirings are respectively a single-bus type, a double-bus type and a 3 / 2-bus type; 1, traversing all buses in the plant station according to the sequence of the voltage levels from high to low, and sequentially judging the wiring type of each bus; 2, respectively establishing different bus groups for the two buses which are judged to be the double-bus type, the two buses which are judged to be the 3 / 2 bus type and the bus which is judged to be the single-bus type; 3, sequentially traversing and searching all the bus groups to find all interval information in each bus group; and searching the wiring modes and the connection intervals of all bus groups to identify themain wiring mode of the plant station. According to the method, the complex plant station main wiring mode is abstracted and simplified, the wiring modes of all buses can be covered, the implementation process is simple, and the situation of misjudgment is not likely to occur.
Description
technical field [0001] The invention relates to the technical field of electric power systems, in particular to an automatic identification method for a main wiring diagram of a plant and station using plant topology information in a power grid dispatching system or a substation monitoring system. Background technique [0002] In the grid dispatching center or substation monitoring, the main wiring diagram of the plant is the most common monitoring screen. At present, most of the main wiring diagrams of the plant are drawn manually according to the wiring mode and interval composition of the substation. Manually drawing the main wiring diagram of the plant and station will increase the workload of the construction and maintenance of the power automation system. Considering that the wiring methods of most substations have certain rules, the use of programs to automatically complete the wiring identification and automatic formation of the main wiring diagram of the plant and st...
