Ship power distribution control system based on intelligent controller

Abstract

The invention discloses a ship power distribution control system based on an intelligent controller. The system comprises a power distribution terminal arranged on a ship and a monitoring terminal connected with the power distribution terminal; the power distribution terminal comprises a wind energy and photovoltaic power generation module, a charging circuit, a storage battery, an inverter circuit, an intelligent controller, a ship electronic appliance electro-module, a ship power electro-module and a security and protection module. The system can measure the voltage, current, frequency, active power, reactive power and power factors of ship electro-equipment, after the measurement and calculation result is obtained, electric energy data is provided for the monitoring terminal through a communication module, an instruction of the monitoring terminal is awaited in real time to control the intelligent controller to be switched on and switched off, and thus the ship electro-equipment connected with the intelligent controller is controlled to be switched off. The ship power distribution control system has the advantages of having multi-protection and being accurate in measuring, highin reliability, practicability and intellectualization, low in cost and the like, the ship electricity cost can be effectively reduced, and the ship is helped to effectively save energy.

Description

technical field [0001] The invention belongs to the field of power distribution intelligent control, in particular to a ship power distribution control system based on an intelligent controller. Background technique [0002] my country's shipbuilding industry has developed rapidly, and now my country has become a major shipbuilding country in the world. More and more countries and regions are ordering and maintaining various ships in my country's shipyards that meet their standards, frequency and voltage requirements; with the penetration of distributed energy resources (Distributed Energy Resource, DER) at all levels of the power system The continuous improvement of the power system, especially the planning and operation of the distribution network, has become relatively complex, and it has also had a greater impact on the economy and supervision of the distribution network. In response to a series of changes such as the gradual expansion of DER scale and the increasing exp...

AI Technical Summary

Problems solved by technology

The access of DER to the distribution network may bring problems to the power grid, such as affecting the short-circuit level, affecting reactive power and voltage distribution, especially the plug-and-play access of new energy, which brings more problems to the operation of the distribution network. The uncertainty of the distribution network makes it more difficult to control
