Abstract

The invention discloses a low-temperature-difference solar energy and ocean energy combined power generation system, comprising a wave energy power generation device, a solar pond, a flash evaporator, a low-temperature turbine, a first power generator, a heat-accumulation boiler, a high-temperature turbine, and a second power generator, which are connected in sequence. The low-temperature-difference solar energy and ocean energy combined power generation system further comprises a first condenser connected with the low-temperature turbine and a second condenser connected with the high-temperature turbine, wherein the first condenser and the second condenser are provided with a same condensate source. According to the low-temperature-difference solar-energy and ocean-energy combined power generation system, the heat-accumulation boiler is additionally arranged to covert surplus power generated during off-peak power consumption into high-temperature heat energy to be stored and convert high-temperature heat energy generated in a power consumption peak period into electric energy to be used, so that the requirements of a storage battery are reduced, the cost is reduced, the stabilityis enhanced, and the service life of the system is prolonged; meanwhile, the power generation system can be comprehensively utilized on the aspects of desalination, refrigeration, cultivation and thelike, and can be used for generating favorable economic benefits while meeting requirements on production, living and coast defence.

Description

technical field [0001] The invention relates to a combined utilization system of solar energy and ocean energy. Background technique [0002] There will be energy and power needs in various aspects such as islands, coasts, and offshore operations, production, life, and national defense construction. There is no condition to use the grid to transmit electricity. However, the use of accumulators is expensive, with limited stability and service life, and if the transportation of fossil energy is used, the transportation costs are high, the risks are high, and there are many accidents. Contents of the invention [0003] The purpose of the present invention is to overcome the problems of high transportation cost, high risk, and many accidents in the prior art, and adopt a new energy independent power generation system, which can effectively solve the above-mentioned solar energy and ocean energy joint utilization system. [0004] In order to achieve the above object, the prese...
