Detailed Description
Various exemplary embodiments, features and aspects of the disclosure will be described in detail below with reference to the drawings. In addition, numerous specific details are set forth in the following specific examples in order to provide a better illustration of 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 in order to not 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 transformer substation, including the following steps:
step S1, providing a basic framework of a bus topological structure;
specifically, the basic bus topology framework is a bus topology structure according to the existing transformer substation, and the basic bus topology structure is designed, as shown in fig. 2, and comprises 4 sections of buses including an I bus, an II bus, a V bus and a VI bus, a #1 switch, a #2 switch, a #3 switch and a #4 switch.
S2, acquiring a substation bus topological structure configuration table, analyzing the configuration table, and acquiring substation bus and switch information in the configuration table;
preferably, the bus topology base frame includes a plurality of buses and a switch connected to the plurality of buses.
Preferably, the substation bus topology configuration table includes the plurality of bus information, the plurality of switch information, and connection information input by a user.
Illustratively, the following tables 1 and 2 show:
TABLE 1
TABLE 2
And step S3, adjusting the basic frame of the bus topological structure according to the bus of the transformer substation and the switch information to generate the bus topological structure of the transformer substation.
Specifically, the bus topology basic frame in the embodiment determines a standard bus topology structure, namely a double bus and double segment structure according to bus structures of different voltage levels of an existing power grid and the development direction of a bus topology structure of a transformer substation of a future power grid. The bus topology of a specific substation is configured on the standard topology to form the actual bus topology of the substation.
As shown in Table 1, if the topology structure of a 220kV bus of a 220kV station is a single bus segmented structure as shown in FIG. 3, the configuration is shown in Table 1, and the II bus and the V bus in Table 1 have association relation with one switch only, so that the topology structure of the bus of the station can be judged to be an open loop structure, and the topology structure takes one section of the II bus and the V bus as a starting point and the other section of the bus as an end point. If a bus or switch does not have an association with other elements (e.g., the #2, 4 switch, and the vi bus in table 1), it indicates that the element is not present. A bus topology as shown in fig. 3 can thus be constructed.
If any bus has an association relationship with two switches, the bus topology of the station is a closed loop structure, such as the topology shown in the configuration of table 2 is fig. 4.
Preferably, if there is only one section of bus associated with any switch in the configuration table or there is an association relation between any section of bus and three or more switches, a prompt message of a bus topology configuration error is output, and a prompt message of a bus topology configuration error is output.
Specifically, in order to avoid human configuration errors in the bus topology configuration table, any one switch in the configuration table has an association relationship with two sections of buses only, and any one section of bus has an association relationship with two switches at most, otherwise, the bus topology configuration error is prompted.
Referring to fig. 5, another embodiment of the present invention provides a system for identifying a bus topology of a substation, including:
a basic frame providing unit 1 for providing a bus topology basic frame;
the configuration information acquisition unit 2 is used for acquiring a configuration table of a bus topological structure of the transformer substation, analyzing the configuration table and acquiring bus and switch information of the transformer substation in the configuration table; and
and the configuration unit 3 is used for adjusting the bus topological structure basic frame according to the substation bus and the switch information to generate a substation bus topological structure.
Preferably, the bus topology base frame includes a plurality of buses and a switch connected to the plurality of buses.
Preferably, the substation bus topology configuration table includes the plurality of bus information, the plurality of switch information, and connection information input by a user.
Preferably, the method further comprises: and the prompting unit 4 is used for outputting prompting information of wrong bus topology configuration if any one of the buses associated with any one of the switches in the configuration table has a relationship with three or more switches, and outputting prompting information of wrong bus topology configuration.
