The invention provides a microgrid system used for sea island power supply. The microgrid system used for sea island power supply effectively utilizes multiple resources and greatly lowers the cost. The microgrid system comprises a boost/step-down transformer, an energy transformation device, a wind power generation system and a diesel generator, wherein the energy transformation device, the wind power generation system and the diesel generator are connected with the boost/step-down transformer; the energy transformation device is connected with a photovoltaic array and a storage battery pack; the boost/step-down transformer is further connected with a garrison load and a resident load. The microgrid system used for sea island power supply is independent of an external power grid, effectively utilizes multiple resources, greatly lowers the cost of a single diesel power supply mode, and achieves seawater desalination while supplying power. A direct current input side connected into the energy transformation device along with the storage battery pack is adopted, so that a grid-connected inverter is omitted; meanwhile, the transformer is additionally arranged in the system, the power supply radius of the system is increased, and electric energy with low loss is provided for a seawater desalination system generally far away from power generation equipment.
Description
Technical field
