Static N-X batch processing method on basis of PSD-BPA

Abstract

The invention discloses a static N-X batch processing method on the basis of PSD-BPA. The static N-X batch processing method mainly includes performing batch processing on verification setting conditions according to equipment types, regions, sections and voltage grades in a classified manner, automatically detecting isolated nodes and island regions in computation procedures and switching on or switching off relevant equipment; automatically analyzing tide results after computation is completed, judging the rationality of the tide results, screening result information concerned by users if the tide results are rational, classifying or making or automatically modifying control conditions according to reasons if the tide results are irrational and performing another computation procedure; performing computation procedures one by one in the same manner, summarizing all batch processing results and displaying the batch processing results in a table form. Compared with an existing verification method, the static N-X batch processing method has the advantages that the static N-X batch processing method can be applied to quickly verifying and computing N-X in a running mode, accordingly, users can be liberated from a large quantity of mechanical and dull repeated data processing work, powerful decision-making support can be provided for the users, and the work efficiency can be greatly improved.

Description

Technical field [0001] The invention belongs to the field of power system analysis, and relates to a method for realizing PSD-BPA-based grid operation mode static N-X verification batch processing calculation and power flow transfer ratio calculation. Background technique [0002] The PSD-BPA program (hereinafter referred to as BPA) was developed by the Chinese Academy of Electric Power Science by introducing, digesting, and absorbing the American BPA program. It has outstanding features such as large scale of calculation, fast calculation speed, and strong functions. It has been planned and designed in my country's power system. Dispatching operation and experimental research are widely used in various departments, and it is one of the important tools of power system analysis and calculation in our country.

AI Technical Summary

Problems solved by technology

[0003] BPA parameters are mainly managed in the form of text files in the form of cards, and the data format requirements are very strict. In the daily static N-X verification and calculation work, since there is no classification management of equipment cards, if you want to modify a certain area, partition, and voltage level in batches The rated value of the line or transformer needs to be modified one by one. The data maintenance workload is heavy and error-prone. If multiple different rated value ratios are to be checked repeatedly, the rated value needs to be restored and modified repeatedly, and a large number of mechanical and boring procedures are repeated. Work

For the calculation of power flow transfer ratio, faults need to be set and calculated one by one, and the power flow values ​​of concerned branches and sections are selected from a large amount of text result information and the transfer ratio i
