A multi-power source system and its scheduling method for unmanned ships

Abstract

The invention discloses an unmanned ship oriented multi-power source system and a method for scheduling the same. The unmanned ship oriented multi-power source system comprises a diesel-driven power generator set, an external alternating-current power source, a lithium iron phosphate power battery pack, a photovoltaic power generation system and a multi-power source scheduling module. Various energy source systems can be scheduled and distributed under the control of the multi-power source scheduling module. The method includes establishing processes for scheduling multi-power energy sources of unmanned ships according to required power of conventional electric equipment under specific working conditions, output power prediction models of the photovoltaic power generation system, output power PG of the diesel-driven power generator set and output power of the lithium iron phosphate power battery pack; scheduling the lithium iron phosphate power battery pack, the photovoltaic power generation system and the diesel-driven power generator set for power supply according to required power of load. The unmanned ship oriented multi-power source system and the method have the advantages that the constitution of multi-power source systems of the unmanned ships and processes for scheduling energy sources under different working conditions are elaborated, accordingly, new energy source systems can be utilized to the greatest extent on the premise that the operating requirements can be met by the performance of the unmanned ships in various aspects, energy can be optimally distributedand controlled, the operating fuel costs of the integral ships can be minimized, and pollutant discharge can be minimized.

Description

technical field [0001] The invention relates to the research field of ship electric propulsion control, in particular to an unmanned ship-oriented multi-power source system and a scheduling method thereof. Background technique [0002] In the 21st century, countries all over the world have shifted their strategic goals from the land to the sea. my country has also put forward the grand goal of further managing the sea and building a powerful ocean country, and adheres to the development path of making the country rich by the sea, strong by the sea, and harmonious by the sea. In 2016, the National Development and Reform Commission, the Ministry of Science and Technology, the Ministry of Industry and Information Technology, and the Central Cyberspace Affairs Commission formulated the "Internet +" Artificial Intelligence Three-Year Action Implementation Plan, and clearly pointed out in the module of "Promoting Intelligent Product Innovation in Key Areas" that artificial intellig...

Problems solved by technology

However, due to the limited energy generated by "green" energy sources such as solar energy, wind energy, and wave energy, the load capacity and battery life are not enough to support large-tonnage unmanned ships for a long time.
