Intelligent fault-tolerant self-healing control method and system for power generation and distribution of ship regional power distribution power system

Abstract

The invention provides a power generation and distribution intelligent fault-tolerant self-healing control method and system for a ship regional power distribution power system, and the method comprises the steps: detecting the ship regional power distribution power system through a data and information collection unit, and obtaining a detection result; the fault diagnosis and classification unit completes fault diagnosis and classification processing; the intelligent fault-tolerant self-healing decision-making unit is used for acquiring a detection result of the data and information acquisition unit and fault diagnosis information of the fault diagnosis and classification unit; the intelligent self-healing coordination and distribution unit is used for receiving the intelligent fault-tolerant self-healing decision scheme; the intelligent fault-tolerant controller is used for receiving a deviation value between a coordinated power generation and distribution instruction and feedback information of intelligent fault diagnosis, carrying out self-healing control distribution according to the instruction, implementing multivariable closed-loop feedback active fault-tolerant control based on fault diagnosis, and finishing intelligent fault-tolerant self-healing control in combination with an intelligent decision; according to the invention, the active fault-tolerant self-healing capability of the power generation and distribution faults of the ship regional power distribution power system is enhanced, and the uninterrupted power supply and distribution capability of the system is improved.

Description

technical field [0001] The invention relates to the technical field of intelligent self-healing technology for power generation and distribution in a ship area power distribution system, in particular to an intelligent fault-tolerant self-healing control method and system for power generation and distribution in a ship area power distribution system. Background technique [0002] The safety and reliability of marine navigation ships is always the top priority of navigation, and the use of regional power distribution is increasing, so as to avoid serious failures of power systems and huge property and personnel losses. The purpose of intelligent fault-tolerant self-healing of power generation and distribution in the ship's regional power distribution system is to provide fault warning and generate intelligent active fault-tolerant control for the power system. Self-healing is an important feature of the smart grid, which can make the power system a more robust autonomous and ...
