Comprehensive energy utilization system for offshore island and operation method of comprehensive energy utilization system

Abstract

The invention relates to a comprehensive energy utilization system for an offshore island and an operation method of the comprehensive energy utilization system. A wind driven generator, a solar photovoltaic module, a wave energy power generation platform and a tidal current energy generator are all connected with a seawater desalination device and a storage battery energy storage device to provide electric energy for the seawater desalination device; the surplus electric energy is stored in the storage battery energy storage device; the reservoir is connected with the seawater desalination device and stores fresh water; the storage battery energy storage device supplies power to the island; the gas turbine is respectively connected with the seawater desalination device and the storage battery energy storage device and is used as a supplementary power supply for power generation; and the gas turbine, the waste heat boiler and the lithium bromide unit are sequentially connected, and the lithium bromide unit supplies cold and heat to the island. The solar heat collector is connected with the heat storage tank; and the water storage pool supplements water to the heat storage tank and the waste heat boiler. According to the system, wind power, photovoltaic energy, wave energy, tidal current energy and other renewable energy sources enriched in the offshore island are fully utilized, and generated clean electric energy meets the power consumption of the island.

Description

technical field [0001] The invention relates to the technical field of distributed energy applications, in particular to an integrated energy utilization system for offshore islands and an operating method thereof, which provide comprehensive energy supply for offshore islands. Background technique [0002] In recent years, with the rapid development of my country's economy and the continuous advancement of marine strategies, offshore islands have become more and more prominent in the development of oil, gas, mining and other resources, maritime transportation, and coastal defense. , expand the living space, and promote the strategic focus of economic and social development. However, the offshore islands have a special environment, and there is a shortage of materials and energy such as fresh water and electric energy. The increasingly serious shortage of electric energy has become a bottleneck restricting the development of offshore islands. At present, the traditional offs...
