Power flow analysis system and operation method

Abstract

The invention discloses a power flow analysis system. The power flow analysis system is characterized by comprising a GIS interface, a database, a power flow analysis module and a power flow processing module; the GIS interface is connected with the database; the database is connected with the power flow analysis module; the power flow analysis module is connected with the power flow processing module; the database is connected with the power flow processing module; the GIS interface is used for guiding a first type data used for analysis; the first type data comprises a network architecture,topological data and electrical parameter data; the database is used for storing the first type data; the power flow analysis module is used for performing power flow calculation and analysis; and thepower flow processing module performs operation load calculation and stores the result in a next variable, wherein one variable has only one operated specified network. The invention also discloses apower flow analysis system operation method. By virtue of power flow analysis, foundation is provided for evaluation of reliability and the power flow optimization effect in advance.

Description

technical field [0001] The invention relates to a power flow analysis system, and also relates to an operation method of the power flow analysis system. The invention belongs to the field of power systems. Background technique [0002] Electric power is the basic industry and energy pillar of the country. The electric power industry is the cornerstone of almost all industries today, providing energy security for the sustainable development of the economy and society. The power grid is the link to maintain the supply and demand of electricity. The security of the power grid is related to national security, economic development and social harmony, and is an important part of social public security. [0003] With the continuous expansion of the power grid in various places such as Nanning, the allocation of power resources has been further optimized, but with the comprehensive deepening of customer service work, the reliable operation of the power grid has faced new challenges...

AI Technical Summary

Problems solved by technology

[0006] In the power system in the 1930s, a dispatch center had been established, but the dispatcher could only command the operation of the system based on operating experience, and was unable to conduct an objective performance evaluation of the operating power system

However, due to the complexity of the dynamic security assessment method, even if only deterministic factors are considered, the calculation process still requires a lot of time, so the combination of dynamic security assessment and probabilistic methods is still difficult to meet the needs of online calculations
