Embodiment Construction

[0021] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0022] The distributed construction method of the topological structure of the land-saving power grid equipment of the present invention comprises the following steps:

[0023] 1. The provincial dispatching system and the local dispatching system model, draw and generate node numbers respectively to form a local power grid topology. Improve the logical rules for node number generation, add the area number as the highest weight number generation factor, and the area number is unique in the entire network:

[0024] Original node number generation algorithm:

[0025] nd=factory station number x10 6 +Voltage level number x10 3 + initial dot number

[0026] The node number generation algorithm after adding the area weight:

[0027] nd = area numbe...

Abstract

The invention discloses a method for constructing a distributed topological structure of provincial power grid equipment, which includes the following steps: (1) constructing a provincial topological structure and a local topological structure respectively for the provincial dispatching system and the local dispatching system, and the nodes are numbered (2) According to the voltage level, split the provincial topology and local topology with the transformer as the boundary; (3) Determine whether all plants and stations have been constructed, and if not, turn to Step (4); (4) Judging whether the current power station is a power station directly under the provincial regulation, if so, complete the construction of the current power station topology and turn to step (3); structure, medium and low voltage side topology, then complete the construction of the current plant topology and turn to step (3). The invention realizes the rapid construction of the topological structure of the power grid in the provincial-land integration system, saves manpower and material resources, and improves the calculation efficiency.

Description

technical field [0001] The invention relates to a method for constructing a distributed topological structure of land-saving power grid equipment in an electric power dispatching automation system, and belongs to the technical field of power grids. Background technique [0002] The grid topology is a valuable resource of the power system. Many problems in the power system are closely related to the grid topology. The structural characteristics of the grid topology can facilitate the processing and practical application of many problems. As the interdependence and coupling between provincial and local grids become higher and higher, it is imminent to realize the integrated operation of provinces and regions and the unified coordinated control of grids. However, the electrical island analysis and static security analysis for the whole network rely on the topology of the grid. The application of the system can provide reliable guarantee and important information support for the...
