Problems solved by technology

[0002] With the development of the times, the scale of the power grid is further expanding; China's power grid dispatching office usually uses PSD-BPA for power flow calculation and grid mode arrangement, but because the grid model structure is becoming more and more complex, when using PSD-BPA to operate There are the following problems: the standardization of BPA data entry in various places is poor, resulting in cumbersome and inefficient work such as data aggregation, merging, splitting and adjustment; BPA has no reliable data import and export objects, and it is difficult to achieve a perfect connection with other systems , and it is not easy to complete batch calculation

Embodiment 1

[0037] refer to Figure 1 ~ Figure 4 , is the first embodiment of the present invention, this embodiment provides a kind of splitting method of BPA grid data, comprising:

[0038] S1: Use the line node matching strategy to perform topology verification on the BPA data file, and normalize the reference voltage and conversion reference power of the BPA data file.

[0039]It should be noted that the topology check of the BPA data file can determine the number of electrical islands, independent suspended buses, electrical islands without power supplies or balancing machines in the power grid to be calculated; Relatively independent scope, "island" is not the concept of "island" on the map, but an abstract definition that is "borrowed" from the geographical point of view to distinguish a certain design scope or function.

[0040] Implementation principle of the line node matching strategy: Traverse the first and last nodes connected by all lines in the network and then match them ...

Embodiment 2

[0092] In order to verify and illustrate the technical effect adopted in this method, this embodiment chooses the traditional BPA power flow calculation method and this method to conduct a comparative test, and compares the test results by means of scientific demonstration to verify the real effect of this method.

[0093] The traditional BPA power flow calculation method: each iteration requires a large amount of calculation, and the bus must first be synthesized and then split during calculation, resulting in long calculation time and poor convergence.

[0094] In order to verify that this method has higher convergence efficiency compared with the traditional BPA power flow calculation method, in this embodiment, the traditional BPA power flow calculation method and this method will be used to calculate and compare the radial network respectively.

[0095] Adjust the output voltage of the generator so that the voltage of the bus X is 100KV, respectively use the traditional BP...

Abstract

The invention discloses a splitting method of BPA network frame data. The method comprises the following steps: carrying out topology check on a BPA data file by utilizing a line node matching strategy, and normalizing the reference voltage and conversion reference power of the BPA data file; constructing a fusion model based on machine learning, and converting the BPA data file into a CIM model by utilizing the fusion model; and splitting the CIM model by using PSDBPA, and exporting the split CIM model in a BPA file format. The conversion efficiency of the BPA data file and the splitting efficiency of the CIM model are improved, and the complexity of load flow calculation is reduced.
