Embodiment Construction

[0047] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods through examples.

[0048] In order to realize the above functions, the embodiment of the present invention adopts the Oracle 10g database management system to establish the database on which the integrated tuning platform relies to integrate multiple application systems. The database data of the relay protection setting calculation platform includes three types: basic data, equipment parameter data and operation mode data. The entities corresponding to the basic data are power grid area information and provincial power grid information; the entities corresponding to equipment parameter data mainly include plant stations and transformers Components and equipment such as bus bars, lines, generators, and series compensation capacitive reactance devices; the operating mode of the entity system and the plant statio...

Abstract

The invention relates to an integrative power system relay protection setting calculation method. The method provides an integrative power relay protection setting calculation data platform, which is of a distributed data platform structure. The method overcomes defects of conventional systems. Servers are gradually built in provincial power distribution center and branch power distribution centers, management platforms and data are also allocated, and multiple resources are integrated, so that an integrative setting calculation method is offered. A software system of the integrative relay protection setting calculation platform adopts a browser / server (B / S) mode. As for overall structure, the software comprises five parts: a user interface, application logic, an application program interface, data service and data exchange with other systems. The overall process of setting calculation sequentially comprises formation of an electric power wiring diagram, short-circuit calculation, setting calculation, off-line verification and management of constant value advice notes. The method is convenient for users to perform setting calculation and greatly improves the setting calculation efficiency.

Description
