Ship power system power generation scheduling management method based on Petri network

Abstract

The invention discloses a ship power system power generation scheduling management method based on a Petri network. A Petri network is used to carry out topology modeling on an electric power system.The system comprises a power distribution sub-network and a power generation scheduling sub-network. The connection relationship of electrical elements in the system and the load access condition of the system can be effectively represented, and the total load capacity of each main distribution board is further determined by using the dynamic updating mechanism of the power distribution sub-network in the Petri network according to the backtracking superposition characteristic of the load power in the system. On the basis, the association matrix and the weight of the power generation scheduling sub-network in the Petri network are dynamically adjusted in combination with the interconnection condition among the main distribution boards, and then the output condition of each generator in thesystem is determined by utilizing the dynamic updating of the power generation scheduling sub-network, so that the efficiency balance of each input unit of the system is realized. The ship power system power generation scheduling management method solves the engineering problems that an existing tide program is difficult to adapt to the characteristics of the ship power system and convergence isdifficult to guarantee, and power generation ship power system management of the ship power system can be efficiently achieved.

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...
