Topic mode based cross-business calculation and analysis system for power system

Abstract

The invention provides a topic mode based cross-business calculation and analysis system for a power system. The cross-business calculation and analysis system comprises a parameter and element management module used for friendly management of parameters and elements, a topic definition module that defines different topics according to business demands and realizes complicated power system cooperative calculation, a topic scheduling module that realizes all functions and optimization scheduling of the topics through a scheduling algorithm, a data sharing module that realizes data sharing of the modules, a memory database used for storing result data, elements and parameters, and a visual display module that visually displays the result data, performs comparative analysis on similar data and performs correlation analysis and data drilling on concerned data. The cross-business calculation and analysis system is oriented to business topics, realizes cross-specialty and cross-department business fusion, adopts a structure formed by originally fusing a plurality of single applications of the power system together according to business logic, and automatically generates fault information in a guide window manner, thereby greatly lowering the difficulty in fault data writing.

Description

technical field [0001] The invention relates to the technical field of power system analysis, in particular to a power system cross-service calculation and analysis system based on a theme model. Background technique [0002] The business of each part of the existing power system is independent of each other and distributed in different regions. Each department only pays attention to its own business, and the methods and models of analysis and calculation of each department are also different. For example, the power flow calculation of the planning department and the dispatching operation department are different. The former uses the estimated load, while the latter uses the actual collected load value. How to realize the integration of business of various departments and the sharing of computing information has always been a difficult point in power system applications. Traditional power system calculations mostly use a single calculation software package, such as BPA, SCO...

AI Technical Summary

Problems solved by technology

Traditional power system calculations mostly use a single calculation software package, such as BPA, SCOPE, etc. The system architecture, calculation model, input parameters and output results of each program package are not exactly the same, but the operation mode of the power grid is complex and diverse, and many practical applications Need to call different functional modules of different packages, which is difficult to implement in the existing mode

Most programs in traditional computing use text input, and each data has a fixed number of columns and positions. Data must be entered strictly according to the rules, which is inefficient and error-prone

Most of the output results also use the text output method, the data is complicated, and the statistical analysis function is lacking

When doing fault analysis, you can only calculate the faults one by one, and you need to manually enter the fault data one by one, which is time-consuming, inefficient and error-prone
