Embodiment Construction
[0053] The steps of a comprehensive evaluation method for power grid operation safety risk based on the evaluation object described in the present invention are as follows:
[0054] The first step is to organize the data and build the input database module;
[0055] The data input into the database module includes historical statistical data of equipment, operating life data of equipment, meteorological data and operation monitoring data; among them, historical statistical data of equipment, data of operating years of equipment and meteorological data are mainly used to calculate the outage probability of equipment; operating monitoring data It is the data related to the operation of the power grid, which is used to analyze and calculate the risk indicators of the evaluation object;
[0056] The second step is to determine the object to be evaluated, and build an evaluation object selection module;
[0057] Due to the complex characteristics of the power grid itself, when con...

A method for comprehensive evaluation of power grid operation safety risks based on evaluation objects, the specific steps are: sorting out data, constructing an input database module; determining objects to be evaluated, and constructing an evaluation object selection module; selecting corresponding evaluation methods for different evaluation objects; calculating evaluation The risk index of the object, build the risk index calculation module; save the evaluation result of the corresponding risk index of the evaluation object in the risk evaluation result database, build the risk evaluation result library module; analyze the risk index result of the evaluation object, and give the weak link of the power grid. The present invention centrally analyzes and processes the basic data of power grid operation safety risk according to different risk assessment objects; analyzes the risk factors of different assessment objects, determines and calculates the risk assessment indicators of different objects, and analyzes the weak links of the power grid; The purpose of comprehensive assessment of power grid operation safety risk based on the evaluation object is realized, and a certain theoretical basis is provided for the safe operation of the power grid.
Description
technical field [0001] The invention belongs to the field of electric power system risk assessment, and in particular relates to a comprehensive assessment method for power grid operation safety risks. Background technique [0002] The risk assessment of power grid operation security is an important way to understand the security status of power grid operation. Risk assessment can be used to evaluate the operational security risks faced by different objects. [0003] The current research methods for power system operation safety are mainly deterministic methods, which seldom consider the randomness of equipment out of operation; the few existing researches on power system operation safety risk assessment are mainly for some specific research objects, and the failure consequences The treatment methods are different, and a relatively complete comprehensive risk assessment system has not yet been formed. [0004] At present, with the promotion of power market reform, the chang...
