Embodiment Construction

[0021] like figure 1 As shown, this expert system-based power plant relay protection rating risk assessment system includes model establishment, risk assessment calculation, risk level determination, and data input and output. The established expert system risk assessment model is stored in the database through the man-machine interface as the basic framework of risk assessment, and then after topology analysis, the model is mirrored in the computer memory, which is convenient for fast data processing, and finally the corresponding data is obtained according to the man-machine interface Evaluate the required information, perform risk assessment calculations on it, and generate risk levels, and store intermediate data in the database for query.

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

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 in particular relates to an expert system-based relay protection fixed value risk assessment system for grid-related power plants. Background technique [0002] For a long time, the integrated operation of the power plant and the network, the relay protection management and setting calculation of the power plant have been in charge of the relevant power grid protection professionals, so the power plant has not paid enough attention to the fault calculation analysis, setting value setting calculation and management work of the relay protection professional , leading to the separation of the power plant and the network, the power plant relay protection profession has become a weak link. Therefore, in order to solve the system operation risk caused by the weak power plant relay protection management and fixed value setting calculation, and learn from the management results of the power ...
