Intelligent fault-tolerant control system and control method for zonal power distribution of full-electric boat

Abstract

The invention discloses an intelligent fault-tolerant control system and a control method for zonal electric distribution of a full-electric boat. A full-electric boat power system is divided into a generator set control sub-system, an electric propulsion control sub-system, a power grid and a power distribution control sub-system of the power grid by a power distribution system; the control mode of each control sub-system is controlled by adopting an intelligent fault-tolerant control method of reference and model identification based on a neural network model; and the control method has a learning function and can be used for improving the control ability of each sub-system on the fault, so that the fault control ability of the full-electric boat power system is improved. With the adoption of a power supply sub-system and a power utilization sub-system of the designed boat power control system, flexible combination of power configuration of meeting navigation requirement of the boat can be achieved, and fault isolation and fault-tolerant control can be carried out. The power system structure and the fault-tolerant control method disclosed by the invention can adapt to safe and reliable requirements of the electric propulsion boat power system on the fault control.

Description

technical field [0001] The invention relates to a regional power distribution control technology of an all-electric ship power system, in particular to an intelligent fault-tolerant control system and a corresponding control method for regional power distribution under the reliable control of an all-electric ship. Background technique [0002] China is a big shipping and shipbuilding country in the world, and there is a great demand for key technologies in the automation of ship power systems. Modern large warships, engineering ships, cruise ships and other ships have begun to use electric propulsion as the driving force for ship navigation due to high requirements for ship mobility, energy saving and environmental protection, which has changed the situation that ships rely on diesel engines as propulsion power, and has produced ship power. The all-electrification revolution of equipment and its control has formed an all-electrification ship with the power system as the main...

AI Technical Summary

Problems solved by technology

At present, the power system of marine ships is mostly in the form of branch-connected power systems and ring-connected power systems, and the ability of the system to control faults is relatively weak; there are also some ship power systems that use regional power distribution, and their control methods are more As a conventional control method, it does not have a strong fault-tolerant control capability for faults; therefore, the current ship power system has a relatively low control capability for faults, and most of them rely on hardware equipment redundancy and relay protection to deal with faults.
