Topological structure identification method suitable for marine power supply network

Abstract

The invention relates to a topological structure identification method suitable for a marine power supply network. The power supply network comprises a switch circuit breaker for controlling a power generation facility, and a bus coupler, a bridging circuit breaker and a broadside bridging circuit breaker which are interconnected in each area of the power supply network. According to the invention, the bus cables at two ends of the bus coupler, the bridging circuit breaker and the broadside bridging circuit breaker are simplified into bus bar nodes; the power generation facility is simplified into unit nodes; potential busbar neighbor nodes and unit neighbor nodes of any busbar node are determined, only one switch circuit breaker needs to exist between two nodes which are potential neighbor nodes, and therefore all the nodes are numbered; and the topological structure of the power supply network is formed by all the busbar nodes with the numbers and the unit nodes. The invention provides a network structure identification method, which is formed by defining two input matrixes, namely a busbar node neighbor matrix and a unit node neighbor matrix and referring to the thought of layer-by-layer search of breadth-first search. With the method, development time can be greatly shortened, and accuracy is improved at the same time.

Description

technical field [0001] The invention relates to a power grid control technology, in particular to a topological structure identification method suitable for a marine power supply network. Background technique [0002] The generator set and the main switchboard part of the ship's power system are usually called power stations. The main wiring of the ship power station refers to the power receiving and distribution circuit formed by the power supply equipment through the switchgear and connecting wires. The circuit diagram that connects the generator and power distribution equipment (symbols) with a single line is called the electrical main wiring diagram. The main wiring of the ship power station is shown as the connection mode of the main busbar (hereinafter referred to as the busbar) in the main switchboard. Usually the number of busbars is small and the busbars are not segmented. For large cruise ships, multiple power stations are usually set up, and the busbars between...
