Power generating set comprehensively using wind energy, solar energy and biomass energy

The utility model discloses a power generating set comprehensively using wind energy, solar energy and biomass energy, which comprises a heat energy circulating system, a power generating system and a cooling system. The heat energy circulating system comprises two closed heat supply loops arranged in parallel and filled with heat energy circulating system working medium, wherein one closed heat supply loop is a solar energy heat supply loop provided with a solar heat transfer device and the other closed heat supply loop is a combined heat supply loop provided with a biomass energy heat transfer device and a wind energy heat transfer device. The two parallel heat supply loops converge and lead to a circulating working medium expansion tank. Then, the heat supply loops realize heat transfer and heat exchange sequentially through a steam overheating booster, a steam generator and a condensate water heater. According to the requirements of the overall system on the heat energy and the solar energy and the wind energy supplied to the system, the combustion heat supply system of the biomass energy is adjusted and controlled, so the heat energy supplied to the overall system is controlled, the matching pressure on the side of the grid is reduced, the solar energy and the wind energy are comprehensively used and scale power generation is realized.
