Abstract

The invention relates to the technical field of electric power operation, specifically to a regulation and control integrated data analysis and aid decision making system and method under ultrahigh-voltage alternating current and direct current networking, and provides a relatively effective guarantee for safe and stable operation of a power grid and relatively intelligent power grid operation risk aid decision making for electric power operation under an ultrahigh-voltage alternating current and direct current hybrid background, so as to rapidly judge and handle a power grid accident. The data analysis and aid decision making system provided by the invention includes a monitoring data analysis and regulation and control integrated operation aid decision making platform, a transformer substation operation risk assessment platform, a monitoring operation intelligent analysis platform and an expert knowledge base. A working method of the system includes the steps of data acquisition and storage, establishment of a monitoring information contrastive analysis calculation model, information screening and preliminary analysis of the calculation model, intelligent analysis of monitoring signals, storage of analysis results, regulation and control signal risk grading, hierarchical comparison and display of data, dynamic alarm prompt of data and the like.

Description

technical field [0001] The invention relates to the technical field of electric power operation, in particular to a data analysis and auxiliary decision-making system and method for integrated regulation under UHV AC and DC networking. Background technique [0002] The safe and reliable operation of the power grid is the basis for the sustainable, healthy and stable development of the national economy. The power supply system is the power source and lifeline to ensure the normal operation of all sectors of society and the people to live and work in peace and contentment. Once a major accident occurs in the power grid and the power supply system is seriously damaged, it will cause major social and economic losses. [0003] In 2013, after the Hami-Zhengzhou UHV DC monopole was put into operation, Henan Power Grid entered a new stage of UHV AC-DC hybrid connection, and the difficulty and pressure on the safe operation of Henan Power Grid increased accordingly. Henan Power Grid...
