Embodiment Construction

[0055] The present invention will be further described below in conjunction with accompanying drawing.

[0056] Such as figure 1 and figure 2 As shown, a method for analyzing the impact of human factors on power grid cascading failures, specifically includes the following steps:

[0057] Step S1. According to the needs of the current operating state of the power grid, analyze the dispatching operation of the power grid dispatcher, and decompose to obtain the included cognitive behavior.

[0058] The cognitive behaviors mentioned include observation behaviors, interpretation behaviors, planning behaviors and execution behaviors;

[0059] Step S2. Analyzing the failure modes contained in the cognitive behavior.

[0060] The failure modes described include wrong target of observation, wrong identification, failure of observation, failure of diagnosis, wrong decision, delayed interpretation, wrong priority, improper planning, wrong way of moving, wrong timing of moving, wrong ...

Abstract

The invention discloses a method for analyzing the influence of a human factor on cascading failure of a power grid. The method comprises the following steps: 1) analyzing dispatching operation of a power grid dispatcher, and decomposing and obtaining the cognitive behavior according to the requirement of the current operation state of the power grid; 2) analyzing the failure mode included in the cognitive behavior; 3) solving the probability basic value HEP0 for occurrence of human failure; 4) analyzing the scene of task operation and determining the level of the behavior influence factor to obtain a failure probability correction factor; 5) solving the human failure probability under specific operation situation; and 6) taking the N-1 fault as the initial condition, performing reliability assessment for the system. The method for analyzing the influence of a human factor on cascading failure of a power grid improves the reliability in operating the power grid.

Description

technical field [0001] The invention belongs to the field of power system reliability assessment, and in particular relates to a method for analyzing the influence of human factors on power grid cascading failures. Background technique [0002] At present, the dispatcher mainly conducts dispatch operations on the power grid based on the real-time operation data of the power grid and personal experience, so as to ensure the reliable operation of the power grid. The application of intelligent electronic equipment, remote program control and intelligent operation ticket system ensures the safety of power dispatching operation to a large extent. But so far, the role of human beings in the dispatching operation process has not been completely replaced by smart devices, and human factors have a great impact on the reliability of dispatching operations. [0003] Through the analysis of major power grid accidents in recent years, it can be found that the human factor plays an obvio...
