Abstract

The invention relates to an electric power system human factor reliability evaluation method based on a CREAM model. The electric power system human factor reliability evaluation method based on the CREAM model includes the following steps that first, common performance condition factors and corresponding status values are acquired, and weight coefficients of all the factors are calculated with the analytic hierarchy method; second, the status values of all common performance conditions are calculated according to the weight coefficients and the corresponding status values; third, the fuzzy CREAM model is built, and fuzzy computation is performed with the common performance condition statue values acquired in the second step as model input, and the final human error probability value is acquired. Compared with the prior art, the electric power system human factor reliability evaluation method based on the CREAM model has the advantages that electric power human operation reliability is improved, and safe and stable operation of a power grid is guaranteed.

Description

technical field [0001] The invention relates to the technical field of power grid operation human factor reliability assessment, in particular to a power system human factor reliability assessment method based on a CREAM model. Background technique [0002] With the advancement of the national smart grid strategy, the deployment of dispatching automation systems, the application of intelligent electronic devices and remote program control technologies have further ensured the reliable operation of equipment. highlight. The prior planning and arrangement of power grid operation, the issuance of dispatching control orders, fault location and elimination, and equipment inspection and maintenance require the participation of operating personnel. However, due to the limitation of their own knowledge level and the influence of external environmental pressure, the operating personnel may not be able to complete the scheduled operations quickly and accurately, resulting in serious ...
