Abstract

An offshore independent power supply system is provided, comprising an offshore floating platform, a solar photovoltaic module, a pumped storage power generation device and a control device. The offshore floating platform comprises an equipment mounting surface, a buoyancy body and an anchor cable. The solar photovoltaic module and the control device are fixedly installed on the equipment installation surface of the offshore floating platform; The pumped-storage power generation device comprises a water storage container, a vent pipe, an inlet pipe, a turbine, a generator, an outlet pipe, a pumping pump and a one-way valve; The inner cavity of the water storage container is communicated with the atmosphere through an air vent pipe, communicated with a pumping pump through an outlet pipe and communicated with a hydraulic turbine through an inlet pipe; Hydraulic turbine and generator drive connection; The one-way valve is installed at the water outlet of the water outlet pipe, and the water inlet of the water inlet pipe is arranged in the water body; The control device is electrically connected with the solar photovoltaic module, the pumping pump, the generator and the island electric equipment through cables. By means of the above, the present application can effectively solve the problem that the prior art cannot provide a stable power supply to the island.

Description

technical field [0001] The present application relates to the technical field of island power supply, in particular, to an independent offshore power supply system. Background technique [0002] There are many large and small islands in the southeast sea area of ​​my country, but due to the limitations of islands’ external transportation and limited available land, the development and utilization of traditional thermal power, hydropower, and renewable energy such as wind power and solar power have been hindered on the islands. [0003] In view of the above problems, the inventors of the present application invented an offshore solar photovoltaic power generation device based on an offshore floating platform, including solar photovoltaic modules, battery energy storage devices, controllers, and inverters (the application publication number is CN107769682A), It can better solve the problem of power supply on islands with insufficient land resources and inconvenient network pow...
