Digital model splicing method of electric power setting calculating system

Abstract

The invention relates to a digital model splicing method of an electric power setting calculating system. The digital model splicing method of the electric power setting calculating system is characterized by comprising the following steps of firstly unifying regulations of the whole grid device naming notations; secondly analyzing boundary equivalent data in each level of an power grid initial model; thirdly splitting and removing the boundary equivalent data in each level of the power grid initial model and retaining inner data in the initial model; fourthly merging the data, namely, merging the inner data in one of the power grid initial models and the actual boundary data in the adjacent power grid initial model; and fifthly exporting a splicing result to a setting calculating data center. The digital model splicing method of the electric power setting calculating system has the advantages that integration of setting calculating data and operation management is achieved and basic data unifying, model unifying, regulation unifying, standard unifying and platform unifying are achieved so that the requirements for 'source port maintenance and whole grid sharing' of an intelligent power grid are satisfied, model information setting and sharing among multi-level relay protection are achieved maximally and problems of 'information isolated island' and the like are solved.

Description

technical field [0001] The invention relates to a digital model splicing method in a power setting calculation system. Background technique [0002] Setting calculation is the core work of dispatching protection at all levels. With the development of computer technology, the application of computer software technology for relay protection setting and professional management has always been a new technology in recent years. From the perspective of application, the protection professions of central survey and ground survey all over the country have applied the setting calculation software. However, most of the software is a stand-alone version of the application, independent of each other, and there are two related power grid systems at different levels and in different regions as external systems, which are reflected in the form of external equivalent models. This traditional equivalent interaction method has led to the formation of "Information islands" lead to information ...

Problems solved by technology

[0009] On the other hand, if the setting calculation based on the integration of centralization and distribution still adopts the method of equivalent simplification, it is difficult for the equivalent interaction to fully match the actual system operation, which will lead to Not accurate enough, laying hidden dangers for protection misoperation or refusal to operate

At the same time, it has not really achieved the goal of network integration.
