Analysis method for safety state of power dispatching instruction

Abstract

The invention provides an analysis method for the safety state of a power dispatching instruction, which comprises the following steps: S1, when a dispatching instruction is detected to be generated, obtaining observation data of a current power grid; S2, analyzing the observation data of the current power grid according to a preset analysis rule to obtain section information of the current power grid; s3, calculating the section information of the current power grid according to a preset calculation rule to obtain power flow information and safety state information of the power grid before and after the scheduling instruction is executed; s4, performing safety state analysis on the trend information and the safety state information through a pre-trained safety state analysis model to obtain a current safety state analysis result; and sending the current safety state analysis result to a dispatcher, obtaining a confirmation instruction returned by the dispatcher, and determining whether a dispatching instruction is issued or not according to the confirmation instruction. The method is adaptive to continuous change of a power grid structure, the possibility of misoperation is reduced, and a large data source is processed in a relatively short time.

Description

technical field [0001] The invention relates to the technical field of power system automation, in particular to a method for analyzing the safety state of power dispatching instructions. Background technique [0002] Power grid dispatching refers to the process of unified command and coordination of the power grid in order to ensure the economical, safe, stable and reliable operation of the power grid, so that all kinds of power production can be carried out in a normal and orderly manner. The good dispatching operation ability of the power sector is the key to effectively solve the power system accidents and ensure the safe and stable operation of the power grid. [0003] The power grid monitoring and dispatching automation system consists of hardware and software of each monitoring and dispatching automation device in the power system, including substation automation, distribution network management system (DMS) and energy management system (EMS). Among them, the energy ...
