Problems solved by technology

The above-mentioned simplified equivalent processing method overcomes the difficulty of data collection caused by the wide-area distribution of power system data resources, and reduces the complexity of system simulation calculations. However, for closely connected power systems, the simplified equivalent brings The error makes its scope of application limited

Embodiment Construction

[0082] A preferred embodiment of the power system multi-area network model splicing method of the present invention shown in FIGS. 7-8 includes a specific power system multi-area network model splicing process realized by the method of the present invention. Other characteristics, objects and advantages of the present invention can also be seen from the description of the embodiments and the drawings.

[0083] The model splicing scheme of the power system network dispatching center and the provincial dispatching center:

[0084] Management mode: Power system network dispatching center, the area under direct dispatch control includes all 500Kv voltage level lines, contact transformers, DC systems, and some 220Kv networks and directly dispatched generator sets. At the same time, at the management level, it has several provincial dispatch centers under its jurisdiction.

[0085] The purpose of model splicing: to splice the grid models of each provincial control center and the ne...

Abstract

A method for pasting-up multi-region network model of power system includes defining model boundary between relevant regions to be pasted-up, guiding file of region to be pasted-up into buffer area A and guiding pasted-up result of last model into buffer area B, using topological dyeing means based on physical node to cut model in buffer area A to be parts, matching objects in two said buffer areas from top to bottom of layer relation, calculating model variable increment, increasing or deleting model object in system databank as per increment result and guiding in the other region model for finalizing paste-up of complete model.

Description

technical field [0001] The invention belongs to the field of electric power technology, and more precisely, the invention relates to a mosaic method for multi-area network models of electric power systems. Background technique [0002] The power system has the characteristics of wide-area distribution, massive parameters, and complex models. Over the years, the production management of electric power has naturally formed a set of "hierarchical management, hierarchical control, and distributed processing" system (such as: national dispatch, network dispatch, provincial dispatch , local dispatch, county dispatch, city dispatch), that is, the power grid is divided into multiple subnets according to the geographical characteristics of the distribution of the power grid, the topology of the network, the electrical characteristics of the power grid, etc., and the dispatch and operation of each subnet is in charge of a dispatch center , each dispatch center owns and maintains detai...
