Abstract

A method of substation-control center two-level distributed modeling for power grid is provided. The method comprises: (1) building a substation model for each of substations, each substation model comprising a network model having a topological structure of the substation devices, parameters of the substation devices and measurement information of each substation devices, and a wiring diagram of each substation based on a whole line identification consistency; (2) uploading each substation model for each of the substations to the control center through a state power dispatching data network; and (3) splicing network models for the substations according to the wiring diagrams of the substations to build a whole power grid model of a whole power grid so as to monitor and control the whole power grid.

Description

technical field

[0001] The invention belongs to the field of power system operation and control, in particular to a modeling method for a two-stage distributed power grid of a substation-dispatch center. Background technique

[0002] In the energy management system (Energy management system, EMS) architecture, it is a computer-based dispatching automation system for modern power systems. Its task is to collect, monitor, analyze, optimize and control the power system in real time. Power grid model and wiring diagram are the foundation and core link of EMS, and the basis of monitoring, analysis, optimization and control. The power grid model includes the topological structure of equipment, equipment parameters, and measurement information. The topological structure and equipment parameters of the equipment include the topology and parameters of equipment such as transformers, lines, generators, loads, switches, isolation switches, and grounding switches. The measurement info...
