Detailed Description
Various exemplary embodiments, features and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings. In addition, numerous specific details are set forth in the following specific examples in order to better illustrate the invention. It will be understood by those skilled in the art that the present invention may be practiced without some of these specific details. In some instances, well known means have not been described in detail so as not to obscure the present invention.
Referring to fig. 1, an embodiment of the present invention provides a method for identifying a bus topology structure of a substation, including the following steps:
step S1, providing a bus topological structure basic frame;
specifically, the bus topology basic framework is a most basic bus topology designed according to an existing substation bus topology, and as shown in fig. 2, the most basic bus topology includes 4-segment buses of I bus, II bus, V bus and VI bus, and #1 switch, #2 switch, #3 switch, #4 switch.
Step S2, obtaining a topological structure configuration table of the substation bus, analyzing the configuration table, and obtaining the substation bus and the switch information in the configuration table;
preferably, the bus bar topology base frame includes a plurality of bus bars and a switch connected between the plurality of bus bars.
Preferably, the substation bus topology configuration table includes the plurality of bus information, a plurality of switch information, and user-input connection information.
Illustratively, as shown in tables 1 and 2 below:
TABLE 1
TABLE 2
And step S3, adjusting the bus topological structure basic frame according to the substation bus and the switch information to generate a substation bus topological structure.
Specifically, the basic framework of the bus topology structure in this embodiment determines a standard bus topology structure, that is, a double-bus double-segment structure, according to the bus structures of different voltage classes of the existing power grid and the development direction of the bus topology structure of the future power grid substation. The bus topology structure of a specific substation is configured on the standard topology structure to form the actual bus topology structure of the substation.
As shown in table 1, in the bus topology configuration table of the present invention, if a 220kV bus topology structure of a certain 220kV station is a single bus segment structure as shown in fig. 3, the configuration thereof is shown in table 1, and the bus of the second bus and the bus of the v bus in table 1 have an association relationship with only one of the switches, so that it can be determined that the bus topology structure of the station is an open loop structure, and the bus topology structure of the station is a structure in which one section of the bus of the second bus and the bus of the v bus is a starting point and the other section of the bus is a terminal. If a bus or a switch is not related to other elements (such as #2, 4 switches and VI bus in Table 1), it indicates that the element is not present. A bus bar topology as shown in fig. 2 can thus be constructed.
If any bus has an association relationship with two switches, the bus topology structure of the station is a closed-loop structure, for example, the topology structure shown in the configuration of table 2 is fig. 4.
Preferably, if there is only one bus associated with any switch in the configuration table, or there is an association relationship between any bus and three or more switches, the prompt message of the bus topology configuration error is output, and then the prompt message of the bus topology configuration error is output.
Specifically, in order to avoid the occurrence of artificial configuration errors in the bus topology configuration table, any one switch in the configuration table only has an association relationship with two sections of buses, at most, any one section of bus has an association relationship with two switches, and otherwise, a bus topology configuration error is prompted.

Preferably, the bus bar topology base frame includes a plurality of bus bars and a switch connected between the plurality of bus bars.
Preferably, the substation bus topology configuration table includes the plurality of bus information, a plurality of switch information, and user-input connection information.
Preferably, the method further comprises the following steps: and the prompting unit 4 is used for outputting prompting information of wrong bus topological structure configuration if any bus associated with any switch in the configuration table has only one section or if any section of bus has an association relation with three or more switches, and outputting prompting information of wrong bus topological structure configuration.
