Medium-voltage electrically-propelled ship power management system and management method

Abstract

The invention relates to a medium-voltage electrically-propelled ship power management system. According to the system, a machine set control panel power transducing device feeds field signals into a machine set controller, and the machine set controller analyzes data and outputs control signals to a joint operating device, a relay set and a machine-side control box; and a PMS controller receives the field signals through the buscouple panel power transducing device, receives commands of a human-machine interface and data in the machine set controller through an Ethernet switch, and transmits control commands to the machine set controller. The system and the method have the beneficial effects that the power management of a medium-voltage electrically-propelled ship power station can be realized; the design is modular, software and hardware interfaces are reserved, the system is independently packaged, and control parameters are adjustable; the load management of different ships can be realized through selecting appropriate interfaces according to types of ship power devices; a load control and simulation platform can also be independently formed, and is connected with other systems through a standardized interface so as to finish system simulation test in a matching manner; and the repetitive work of designers can be effectively avoided, and thus, the time for system development is saved.

Description

technical field [0001] The invention relates to a ship automation equipment, in particular to a medium-voltage electric propulsion ship power management system. Background technique [0002] The existing electric propulsion ship power management mainly has the following disadvantages: [0003] 1. Lack of generalized, standardized and modularized power management system products: [0004] At present, most of the standardized ship power management systems on the market are designed for conventional power ships. The PPU of DEIF company, the SIGMA series and Flexgen series power management system of SELCO company have a large market share. Their product design, system function and control strategy 1. The hardware interface is different from that of electric propulsion ships, and cannot be directly used for power management of electric propulsion ships. Most of the existing power management systems for electric propulsion ships are controlled by PLC. There are many types of con...
