Ship DC regional power grid topology reconstruction and visualization method based on balance optimizer

Abstract

The invention relates to a ship DC regional power grid topology reconstruction and visualization method based on a balance optimizer. A ship regional power grid is used as a carrier, a connectivity rule and a shortest path method are used, and a shortest power supply path from a power supply to a load is judged, so that a corresponding load power supply is determined; judging whether the total power of the load connected with the power supply is overloaded or not, and if yes, unloading the load according to the importance degree of the load and the priority level; after the power constraint unloading load is met, if the power supply in the corresponding area still has redundancy and can supply power to part of the unloading load, an improved balance optimizer is used for optimization solution with the maximum power supply limit and the minimum switching operation times as targets; and after the power constraint is satisfied and the load is unloaded, if each power supply does not satisfy the power supply to any load, directly outputting a reconstruction result. The system can resist the influence on power supply of a ship regional power grid under various emergency conditions, provides powerful power support for ships on the sea, and meets the actual requirements of the ships.

Description

technical field [0001] The invention belongs to the field of fault intelligent reconstruction and visualization operation of a ship's DC area power grid, and in particular relates to a topology reconstruction and visualization method for a ship's DC area power grid based on a balance optimizer. Background technique [0002] Most of the early ship power grids used the front and rear power stations as backup, that is, dry-feed power supply. The main power supply and the backup power supply were connected to the same busbar (busbar) to supply power to all loads. However, when a short circuit occurs near the busbar, the load will lose power, and the redundancy is 100%. Therefore, the power supply reliability is low, and there is no good redistribution of load priorities. Therefore, the traditional radial power system and reconstruction technology can no longer meet the power supply requirements of large and medium-sized ships. With the development of high-power power electroni...

Problems solved by technology

However, the convergence speed is long and the quality of the local and global optimal solutions obtained due to the randomness of the algorithm is poor, so it cannot be well applied to the ship power grid

When the ship's power grid is damaged, the normal power supply of important loads cannot be responded in time, which cannot meet the actual working needs of the ship

On the other hand, most refactoring methods are still stuck on code simulation, which makes the results relatively monotonous and may not be effectively utilized on the grid
