Problems solved by technology

[0005] The traditional power grid risk assessment theory and technology focus on establishing a risk assessment and early warning system from the macro level. The data source used is single, the amount of data is small, the correlation between the established risk assessment model and the data is not strong, and the risk assessment indicators given are single. , one-sided, cannot comprehensively reflect the type and severity of risks faced by the power grid from multiple dimensions such as time and space
The risk mechanism analysis and risk source identification in the existing technology are highly dependent on data, but at the current stage, the information is incomplete, the amount of data is small, and there are barriers between data source systems, making it difficult to analyze the risk mechanism

Abstract

The invention discloses a grid security risk management and control intelligent evaluation method. According to the technical scheme of the invention, the current operation data and the historical operation data of power distribution network equipment during the healthy operation process are obtained, and then a failure probability model is constructed. In this way, the operational risk of the power distribution network can be quickly determined. Compared with the prior art, the complexity is low, and the evaluation efficiency is high.

Description

[0001] Technical field [0002] The invention relates to the field of power transmission and distribution, in particular to an intelligent evaluation method for power grid security risk management and control. Background technique [0003] The smart distribution network is an important part of the power grid. With the increasing requirements of users for power quality in recent years, the improvement of the overall performance of the distribution network has become an important part of the sustainable and healthy development of the power industry. The failure of the distribution network is an important factor affecting the quality of power and the reliability of power supply. Only when the safe and stable operation of the distribution network is ensured can the safe and reliable operation of the entire power grid be guaranteed. Therefore, it is very necessary to carry out more work in the field of distribution network security defense, and to conduct research on the risk asses...
