Embodiment Construction

[0043] The content of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0044] The AC field structure of the DC system is generally a double-female three-half connection, and the number of nodes k is greater than the number of breaker intervals n (k>n). The number of rows and columns of the following different types of matrices is equal to k, and the physical meanings represented by the corresponding rows and columns are consistent.

[0045] 1. AC field topology matrix: T matrix

[0046] Different AC field wiring methods have different final circuit breaker logics, so the general algorithm should fully reflect the topology of the AC field. Mathematical modeling uses matrix as a tool to construct the AC field topology matrix T matrix. If it is stipulated that each row of the matrix represents a node of the AC field, and the corresponding column (column number is equal to the row number) ...

Abstract

The present invention provides a matrix-based method for automatically judging the logic of the last circuit breaker, which includes the following steps: Step 1, establishing the AC field topology matrix; Step 2, constructing the connectivity matrix; Step 3, constructing the node attribute matrix; Step 4, calculating the AC field Field state matrix; step 5, criterion: step 51, when satisfying that there is an element equal to X in any row in the AC field state matrix, and the row contains an element equal to Y and an element equal to Z; step 52, obtaining the judgment The new AC field state matrix corresponding to the open circuit breaker interval; Step 53, when not satisfying that there is an element equal to X in any row in the new AC field state matrix, and this row contains an element equal to Y and an element equal to Z element, the disconnected breaker interval is the last breaker. The invention has the advantages of convenient modification, time-saving and simple maintenance, and is conducive to timely restoration of electricity at the production site.

Description

technical field [0001] The invention belongs to the technical field of high-voltage direct current transmission, and in particular relates to a matrix-based method for automatically judging the logic of the final circuit breaker. Background technique [0002] The algorithms used in the final circuit breaker judging program of the existing DC project are all enumeration methods. The method is to judge the switching mode according to the characteristics of the final circuit breaker subjectively according to the structural characteristics of the AC field of the DC project, enumerate each working condition of the final circuit breaker, and then write each working condition separately into a paragraph about the switch state A program of logical combinations of AND or NOT. [0003] This algorithm does not have a unified criterion for final circuit breaker judgment, but is based on human subjective judgment. Therefore, there may be unreliable factors such as judgment errors, depen...
