Solar ORC power generation system and power generation method thereof

The invention discloses a solar ORC power generation system and a power generation method of the solar ORC power generation system. Solar energy can be utilized to generate power, and therefore the heat energy utilization rate is high. The solar ORC power generation system mainly comprises a heat exchanger which is connected with a solar heat source, a power output device, a generator which is connected with the power output device, a circulating pump and a condenser. The solar heat source comprises solar heat collecting panels, an oil storage tank and a conduction oil circulating pump. The solar heat source further is further provided with a heat regenerator. The heat regenerator is used for conducting heat exchange on an organic working medium discharged by the power output device and an organic working medium discharged by an organic working medium circulating pump, and therefore remaining heat energy of the organic working medium discharged by the power output device can be fully utilized. The solar ORC power generation system is used for power generation, therefore, heat energy can be effectively utilized, energy saving is facilitated, and system device cost is reduced.
