Specific embodiment
The technical solution in the present invention is clearly and completely described below, it is clear that described embodiment is only
A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
Every other embodiment obtained without creative labor, shall fall within the protection scope of the present invention.
Calculated result screening technique provided by the present invention based on PSD-BPA the following steps are included:
S1, the different types that calculate inside PSD-BPA system are pre-processed, i.e., in power system operation mode data
Setting screening precondition before calculating, is arranged data subregion to every kind of calculating type；Each subregion include: respective route,
The data of each subregion are carried out division mark by the data of transformer, load and generating set；Calculating type includes: normal side
Load flow calculation, N-1 Load flow calculation and multilayer output feedback network under formula.
Load flow calculation, N-1 Load flow calculation, maintenance N-1 under the existing normal mode to power system operation mode data
The calculated result of Load flow calculation and multilayer output feedback network lacks then thousands of rows, more rows then up to ten thousand, and the result to be analyzed in fact only needs
Wherein tens rows even several rows, calculation result data in addition is extra for analysis.Trend meter under in the normal fashion
For calculation, data line is up to up to ten thousand after Load flow calculation, wherein only need to check whether calculating restrains, the number of iterations be it is how many, be
No wrong prompt and line load rate.
S2, every kind of calculating data for calculating type needs are not quite similar, and screening rule also becomes because the criterion of analysis changes
Change, it is therefore desirable in the calculated result of the different calculating types of S1, the screening conditions of different dimensions are set, specific as follows:
