PSD-BPA-based upper and lower power grid operation methods network model integration system

Abstract

Disclosed is a high-and-low-level grid operation mode network model integration system based on PSD-BPA. According to the system, a grid computing device foundation database is established, the corresponding relations between dispatching units and devices are maintained, and meanwhile, card information each dispatching unit can manage is determined according to the corresponding relations among dispatching units, devices and BPA cards; high-level dispatching units send modes to low-level dispatching units through parallel or serial strategies; when the low-level dispatching units maintain corresponding modes, modified contents are automatically compared with an original issuing mode to obtain differential contents; the low-level dispatching units complete corresponding modes and call the PSD-BPA to submit the differential contents to the high-level dispatching units through power flow calculation and stability calculation; the high-level dispatching units extract the differential contents submitted by the low-level dispatching units to automatically conduct combination on the modes submitted by the low-level dispatching units one by one, and automatically calls the calculation command of the PSD-BPA to conduct power flow calculation and stability calculation. According to the high-and-low-level grid operation mode network model integration system based on the PSD-BPA, users are liberated from a large amount of boring data processing, and working efficiency is improved greatly.

Description

technical field [0001] The invention belongs to the technical field of electric power systems and automation thereof, and more precisely relates to the distribution and merging of power grids under multi-level regulation and control units. Analysis software package, which is collectively referred to as PSD-BPA in this paper), distributes power flow and stability methods of upper and lower power grids and integrates network models. Background technique [0002] At present, my country is divided into five levels from top to bottom: national survey, network survey, provincial survey, local survey and county survey. With the rapid development of the national power system, the types and quantities of equipment managed by the power dispatching department are increasing, showing the characteristics of massive data and various models. In addition, with the clarification of dispatching authority, the hierarchical and partitioned management mode of power dispatching departments at al...

AI Technical Summary

Problems solved by technology

[0005] 1. PSD-BPA maintains model parameters in the form of text cards. This maintenance method is not easy to locate the data, and the modification is prone to errors

[0006] 2. The operation mode data is interacted in the form of text files, and the authority division of the dispatching organization to which each device belongs is not clear, which may easily cause data to be incorrectly modified

[0007] 3. When the upper-level dispatcher merges the submission methods of the lower-level dispatcher, it needs to compare the text and modify the parameters of the changed devices one by one. The data integration is cumbersome, very inefficient, and error-prone

[0008] 4. The data submitted by the lower-level scheduling in text form does not have a good detection mechanism, and it is impossible to actively judge the correctness of the data submitted by the lower-level scheduling before the lower-level submission method

[0009] 5. It is impossible to conduct statistical analysis on the data modified by the lower-level dispatcher, and it is difficult for the upper-level dispatcher to fully grasp the adjustment of the operation mode of the power grid in each lower-level region
