Problems solved by technology

[0004] However, in the power operation risk assessment method of "risk degree = possibility * severity of consequences", the definition of "possibility" and "severity of consequences" has serious subjective components, and the boundaries between the division levels are not clear, making it difficult to It is more difficult to conduct specific qualitative and quantitative analysis of power operation risks, resulting in large risk assessment errors, which are not suitable for specific power operations

Abstract

The invention discloses a high-risk assessment system in the operation process of a power system. The system comprises a data collection station, a data processing platform, and a risk assessment system, the data collection station is in wireless connection with the data processing platform, and the data processing platform is in wireless connection with the risk assessment system. According to the invention, with the data acquisition station, the data processing platform and the risk assessment system, a data acquisition module acquires danger generation data of each monitoring point in a power system; the acquired dangerous data are transmitted to the data processing platform; the data processing platform performs data analysis on the acquired dangerous data; the risk generation probability is estimated, the estimation result is sent to the risk assessment system, the risk assessment system performs risk assessment analysis by combining the acquired risk data and the estimation result, the stability of the power system is judged, and various risk generation conditions in the power system are predicted.

Description

technical field [0001] The invention relates to the technical field of power system risk assessment, in particular to a high-risk risk assessment system during power system operation. Background technique [0002] Power operations run through all links of the power system. Through the measurement, regulation, protection, communication and dispatch of the production process of electric energy, the normal operation of the power generation, transmission, transformation and distribution of the power system can be realized, thereby ensuring Electricity users obtain safe, economical and high-quality electric energy. Due to the existence of a large number of electrical equipment in the power system, electrical personnel are often in a relatively dangerous electrical operation environment, so it is particularly important to assess and control the risks in electrical operations. [0003] In the prior art, the risk in electric power operation is usually evaluated by using "risk degre...
