On-line platform-based power grid accident pre-arranged plan automatic realization method

Abstract

The invention discloses an on-line platform-based power grid accident pre-arranged plan automatic realization method which comprises the following steps: a forecast trend of a power grid is obtained; an anticipated accident set is established; emergency control aid decisions and control objects and post-accident power grid preventive control aid decisions and control objects for the anticipated accident set are generated; an accident pre-arranged plan is generated and is chosen as a matching pre-arranged plan, and therefore a power grid accident pre-arranged plan is realized. According to the on-line platform-based power grid accident pre-arranged plan automatic realization method provided in the invention, based on an on-line safety and stability analyzing system, complete power grid accident pre-arranged plan automatic realization processes are designed via strict trend prediction, scientific accident anticipation and fault surface search, and mature operation analysis check and control aid decisions; a function mechanism via which power grid accident pre-arranged plans can be automatically edited, the pre-arranged plans can be instantly popped out when accidents occur and safety monitoring of whole processes can be realized is established; improvement and high-efficiency application of pre-arranged plan quality are facilitated, and labor intensity and accident processing risk of dispatchers are lowered.

Description

technical field [0001] The invention belongs to the field of electric power system automation, in particular to an online platform-based automatic realization method of a power grid accident plan. Background technique [0002] With the development of national economy and technology, the degree of automation of the power system has become higher and higher. How to make the power grid run stably and automatically has become one of the main research directions of the power system. [0003] The online safety and stability analysis system (hereinafter referred to as the online system) is characterized by big data, accurate simulation, parallel computing, automatic analysis, etc., and has the functions of safety analysis and auxiliary decision-making. The whole process safety monitoring provides a good platform. On the one hand, based on the target power flow of the power grid, the online platform can quickly and synchronously implement six types of safety analysis and give corre...

AI Technical Summary

Problems solved by technology

The workload of this process is heavy, and it is difficult to guarantee the accuracy, completeness and implementation effect of the plan due to the influence of offline power flow and personnel analysis level

And for a long time, the preparation of power grid accident plans has been done manually, and most of the plans have not been implemented in the end. The mentality of relaxing vigilance has caused the plan mechanism to gradually become a mere formality

At the same time, the contingency plan is generally archived and managed. Once an accident occurs, guidance cannot be provided immediately, which is not conducive to accident control.
