Embodiment

[0057] Taking the power grid data of a certain region as an example, the preferred embodiment is described in detail for the OPEN3000 system (a new generation of EMS system developed by NARI Group). The construction method of the graphic platform of the distributed power flow computing system based on WEB-SVG includes the following steps:

[0058] 1. First, derive the initial network model from the OPEN3000 system. Since the existing power grid model cannot be directly used for distributed computing, and it is difficult to independently model distributed computing, it is necessary to study the distribution based on the existing EMS. modelling. The integrated modeling method of distributed computing is adopted here, that is, the network splitting technology based on BUS model and the network merging technology based on virtual connection are introduced. Model. Then a hierarchical database is established locally, and the obtained power grid model is imported into the hierarchi...

Abstract

The invention discloses a construction method of a distributed tide computing system graphics platform based on WEB-SVG (Scalable Vector Graphics), and belongs to the technical field of electric system energy management. The method comprises the steps that a distributed computing model is established; a power grid model is led into a local hierarchic database; an original SVG data file in an EMS (Engine Management System) is led out; an SVG file with interactivity is generated; a local real-time database model is updated in real time; graphics and model integration is realized; an Apache server is deployed as a control center of a whole WEB release system; communication is realized between subsystems and a coordination layer by a common object request broker architecture (CORBA) port by adopting a decomposition coordination mode; a distributed tide computing main program is developed; and a system management part and a computing part are mutually independent. The method achieves display of complex graphics and refreshing of real-time data, and is applied to distributed tide computing first; a practical graphics platform construction method is provided for a distributed computing system; and a foundation is laid for popularization and application of the distributed computing system.

Description

technical field [0001] The invention relates to a method for constructing a graphic platform of a distributed power flow calculation system based on WEB-SVG, and belongs to the technical field of power system energy management. Background technique [0002] At present, the current energy management system (EMS) of the power grid control center adopts its own independent calculation mode. This calculation mode cannot capture the changes of the external network, so it cannot guarantee the correctness of the calculation of various advanced application software in the internal network. . In order to obtain the correct response of the intranet when any point in the network is disturbed, distributed computing of the interconnected system is required. At the same time, from the perspective of my country's power grid structure, the contradiction between power grid interconnection and dispatch control decentralization also determines the need to use the decomposition and coordinatio...
