Embodiment Construction

[0021] Such as figure 1 As shown, this expert system-based power plant relay protection fixed value risk assessment system includes model establishment, risk assessment calculation, risk level determination, and data input and output. Store the established expert system risk assessment model in the database through the man-machine interface as the basic framework of risk assessment. Then, after topology analysis, the model is mirrored in the computer memory to facilitate rapid data processing, and finally obtain the corresponding data according to the man-machine interface Evaluate the required information, perform risk assessment calculations on it, thereby generating risk levels, and store intermediate data in the database for query.

[0022] According to the characteristics of the power plant protection device, this method performs qualitative and quantitative analysis and measurement on the fixed value of the relay protection of the power plant, reduces the risk caused by the ...

Abstract

The invention discloses a grid-related power plant relay protection fixed value risk evaluation system based on an expert system. The grid-related power plant relay protection fixed value risk evaluation system is high in operability, high in efficiency and scientific and comprises building of a model, risk evaluation calculation, determination of the risk class and input / output of data.

Description

Technical field [0001] The invention belongs to the technical field of relay protection, and specifically relates to an expert system-based relay protection fixed value risk assessment system for power plants in a network. Background technique [0002] For a long time, the integrated operation of the power plant and the grid, the power plant relay protection management and fixed value setting calculation have been responsible for the relevant power grid protection professional, so the power plant has not paid enough attention to the fault calculation analysis, fixed value setting calculation and management work of the relay protection professional After the separation of the power plant and the grid, the power plant relay protection profession has become a weak link. Therefore, in order to solve the system operation risks caused by weak power plant relay protection management and setting calculations, and to learn from the management effectiveness of the power system peers, it is...
