Method for implementing plan security check on basis of power grid operation service bus

Abstract

The invention provides a method for implementing plan security check on basis of a power grid operation service bus and aims to solve the problem that a power grid dispatch automation system is lack of a universal plan check method. Firstly, plan check data are obtained, power grid plan data and load prediction data are gathered through the power grid operation service bus in the power grid dispatch automation system, and the plan check data are subjected to data decomposition according to a plan object; then a future mode fracture surface is generated and security check is performed, a power grid flow model of a checked point is corrected according to the plan data so as to form a predicted flow fracture surface at a future plan moment, and power flow calculation and static security analysis are called through the power grid operation service bus to perform security check on the future mode fracture surface; finally, plan security check services are established, the predicted flow fracture surface and check result information at the future plan moment are output through the power grid operation service bus, and plan check is performed through arrangement of the plan security check services in terms of each application system or module.

Description

technical field [0001] The invention relates to the field of power grid dispatching automation system, in particular to a method for plan security checking based on power grid operation service bus in the power grid dispatching automation system. Background technique [0002] As the structure and operation mode of the power system become more and more complex, in order to ensure the safety and economy of the power system operation, dispatching and operating personnel are required to evaluate the safety of the future power grid operation in advance. Power grid operation planning data and corresponding safety analysis information should be fully grasped and considered comprehensively. [0003] In the dispatching automation system, the sources of planning data are scattered, including the day-ahead power generation plan accessed by external systems, and the power generation plan modified by the dispatcher in real time. The same situation also includes inter-regional connection ...

AI Technical Summary

Problems solved by technology

These data modules often have different data acquisition methods due to differences in construction time and construction parties, which brings inconvenience to the safety analysis of future operation methods

In addition, different scenarios in the dispatch automation system also have different requirements for plan verification, including preliminary comparison and rolling verification of day-ahead plans, verification of intraday plans, and verification of real-time power grid operation plans. Third-party systems or applications require plan verification. These plan verification scenarios often lack a common implementation method, resulting in repeated construction of system functions
