Independent power supply system for islands
2012
The invention discloses an independent power supply system for islands, which belongs to the technical field of power control and is used for meeting the power supply demand of the remote islands. The independent power supply system comprises a power supply device, a control center and an electric energy controller, wherein the power supply device comprises a wave power generation unit, a first inverter, an ocean current power generation unit, a second inverter, a first storage battery pack unit, a first two-way chopper, a second storage battery pack unit, a second two-way chopper, a flywheel energy storage unit and a third two-way inverter, wherein the first storage battery pack unit and the second storage battery pack unit charge and discharge alternately; and the electric energy controller controls the first storage battery pack unit or the second storage battery pack unit to output voltage and current according to active power-frequency droop control coefficients and reactive power-voltage droop control coefficients, and controls the wave power generation unit and the ocean current power generation unit to output voltage and current according to the set active power and the set reactive power. The independent power supply system provided by the invention realizes power supply of the remote islands.
