Problems solved by technology

The "search and replace" function provided in the PSD calculation software cannot adapt; the data modification needs to be modified separately for the power flow file and the stable file, which cannot be modified simultaneously, which will easily lead to errors and omissions of the modification; manually modifying one by one requires hundreds of changes to the entire regional power grid Thousands of substations are modified, the work is repetitive and cumbersome, and the workload is huge, and the data in the PSD software is not allowed to be misplaced, which can easily lead to data misplacement

Embodiment Construction

[0039] The specific embodiment of the present invention will be described in further detail below in conjunction with the drawings, wherein the same symbols in all the drawings represent the same or similar components, and the drawings in the description are in simplified form and are only for understanding the specific structure of the present invention. The following examples are only used to illustrate the technical solutions of the present invention more clearly, but not to limit the protection scope of the present invention.

[0040] Such as figure 1 As shown, it is a directory tree established by the present invention for an actual regional power grid according to the four levels of partition, substation, busbar, line or main transformer. Among them, N1, GX, NN, BS, etc. are partitions; Xiangzhou, Debao, Laoqu, Naxiong, Longlin, Yunling, etc. are substations under a certain voltage level under the BS partition; LONGL21 and LONGL22 are substations under Longlin substation...

Abstract

The invention discloses a PSD-BPA flow data element editing and bus switching method, belonging to the field of statistic data and analysis. The method comprises: 1) reading a flow file and a stabilization file, and building respective objects for circuits, transformers and buses in the flow file, wherein the properties of the objects comprise various parameters in the flow file and the stabilization file, a line number in each file, and whether being noted or not; 2) creating a directory tree; 3) creating a bus switching method; 4) synchronizing stabilization data files. Rapid editing on PSD flow and stabilization calculating data when the buses are added or deleted, and components (power transmission lines and the transformers) connected with the buses are switched, and a simple annotation editing function on the components (the power transmission lines, the buses and the transformers) is added, thus avoiding the problems of heavy workload and great error possibility during single and manual modification one by one, and greatly improving the work efficiency.

Description

technical field [0001] The invention belongs to the field of statistical data and analysis, in particular to a method for editing PSD-BPA power flow data elements and switching buses. Background technique [0002] The PSD power system analysis program is a power system simulation calculation and analysis software package developed by the China Electric Power Research Institute. It includes multiple calculation programs such as power flow, stability, short-circuit current, and small disturbance calculation and analysis. It is widely used in power system simulation calculation analysis and planning. and other fields. [0003] In the actual power grid wiring system, if the busbar of a certain voltage level in the substation has sections and the bus tie switch is put into operation for a long time, only one busbar node is generally reserved in order to simplify the workload when setting the busbar node for the power flow calculation data of the conventional operation mode. When...
