Problems solved by technology

The search method is to analyze the network topology by searching the connection relationship between nodes and adjacent nodes. The principle of the search method is simple and easy to understand, but the programming is cumbersome; the matrix method expresses the connection relationship between nodes as an adjacency matrix, and then performs Matrix operations are used to perform topology analysis.

Embodiment Construction

[0069] The present invention will be further described below in conjunction with accompanying drawing. Figure 4 It is a physical model of a simple power system network, including 3 plants and 4 voltage levels, among which the voltage level KV1 of plant 1 has 8 nodes, the voltage level KV2 of plant 2 has 4 nodes, and the voltage level KV2 of plant 3 has 4 nodes. One voltage level KV3 has 2 nodes, and the second voltage level KV4 of plant station 3 has 6 nodes. The nodes are numbered according to the voltage level, and the isolating switch is omitted in the figure. according to Figure 1 ~ Figure 3 The process shown for Figure 4 The steps of performing network topology analysis on the physical model of the simple network shown are as follows:

[0070] Step 1: Compile the node switch association table, node branch association table, node information table, and bus bar information table of the analyzed power grid.

[0071] Step 2: Set the voltage level flag KV=1 for the curre...

Abstract

The invention relates to a matrix analysis method of power system network topology, which still utilizes the advantages of a matrix method to obtain a full-access matrix by two matrix multiply operations and improves matrix analysis speed. The matrix analysis method comprises the following steps of: optimizing and numbering nodes according to the number of closed switches connected with the nodes from big to small and optimizing and numbering a bus according to the number of branch circuits connected with the bus from big to small, thereby reducing the matrix multiply operand; and preserving values of a communication matrix and the full-access matrix by directly using adjacency matrixes without needing a special sandwich matrix in order to save a half of a computer storage space and reduce matrix assignment operation. Compared with the traditional matrix method, the matrix analysis method has smaller calculation amount and the more obvious efficiency the more top points.

Description

technical field [0001] The invention relates to a network topology analysis method of a power system, in particular to a power system network topology analysis method based on a matrix method. Background technique [0002] The network topology analysis of the power system is a very important module in the energy management system and distribution management system of the power company. Its function is to transform the physical model of the power system into the mathematical model required for network analysis. The physical model of the power system describes the relationship of all primary equipment in the power system connected together through nodes, including generators, loads, lines, transformers, capacitors, reactors, circuit breakers, disconnectors, etc. In order to analyze the power system, it is necessary to form a circuit model reflecting the relationship between the busbar and the branch through network topology analysis. [0003] Network topology analysis include...
