Problems solved by technology

[0003] With the widespread use of various modern and intelligent technologies such as artificial intelligence, the current power grid requires multi-dimensional and three-dimensional information processing, fast and agile online monitoring, and comprehensive and comprehensive analysis of monitoring data. However, traditional The operation evaluation method of the power grid dispatching control system still mainly adopts the offline analysis method, which leads to the low accuracy of the data model and the large deviation of the accuracy of the analysis results.

Abstract

The invention belongs to the field of power grid dispatching automation, in particular to a method and system for evaluating the operation state of a power grid dispatching control system, including generating a state evaluation model based on historical fault logs of each monitoring point; The model is used to obtain the evaluation result of the current operation state; based on the evaluation result of the current operation state, the risk warning is carried out for the operation state of the power grid dispatching control system. The present invention sets up monitoring points by analyzing the system function failure and system performance failure scenarios, and learns the correlation relationship between the monitoring point data change trend or the functional state change trend and the fault; and the fault tree is used to analyze the monitoring point data change or functional state change and the occurrence of the fault. It establishes a state evaluation model, monitors the dynamic changes in the system operation in real time, and realizes the online evaluation and risk early warning of the system operation state.

Description

technical field [0001] The invention relates to the technical field of power grid dispatching automation, in particular to a method and system for evaluating the running state of a power grid dispatching control system. Background technique [0002] With the rapid development and utilization of renewable energy in my country under the new situation, a series of random and intermittent wind power and photovoltaics are connected to the power grid, which significantly increases the uncertainty of the operation mode of the power grid to a large extent. Especially due to the influence of factors such as external environment and the health status of power equipment, the safe and stable operation of the power system is also threatened. With the refinement of power grid dispatching control and management requirements, the application requirements of power grid dispatching control systems are increasingly practical and complex, the requirements for data sources are diversified, and t...
