Abstract

A Petri net-based power generation dispatching management method for a ship power system. The Petri net is used to model the power system topology, including two parts, the distribution sub-network and the power generation dispatching sub-network, which can effectively characterize the connection relationship of each electrical component in the system and the system Then, according to the retroactive superposition characteristics of the load power in the system, the total load of each main switchboard is determined by using the dynamic update mechanism of the distribution sub-network in the Petri network. On this basis, combined with the interconnection between the main switchboards, dynamically adjust the correlation matrix and weight of the generation dispatching sub-network in the Petri network, and then use the dynamic update of the generation dispatching sub-network to determine the output of each generator in the system , to achieve the efficiency balance of each input unit in the system. The power generation scheduling management method of the ship power system solves the engineering problems that the existing power flow program is difficult to adapt to the characteristics of the ship power system and the convergence is difficult to guarantee, and can efficiently realize the power generation dispatch management of the ship power system.

Description

technical field [0001] The invention belongs to the technical field of ship power system automation, and in particular relates to a method for dispatching and managing power generation of a ship power system based on a Petri net (a discrete parallel system network). Background technique [0002] As a limited grid with independent activities, the ship's power system will be cut off when it encounters a fault, so that some loads and even important loads will lose power supply. This requires network reconfiguration of the ship's power system to ensure the maintenance of power supply in a large area, ensure uninterrupted power supply to the most important equipment, reduce and limit the destructive impact of power equipment and networks to a minimum, and improve the ship's safety. power stability. [0003] The power generation dispatching management of the ship power system is an important basis for realizing the network reconfiguration of the ship power system. Whether the rec...
