  • Received Date: May 08, 2017
  • The article mainly solves the problem of the idea and method of the calculation of the auxiliary power in the field of solar thermal power plant design. Solar thermal power generation has become an important development direction of China's new energy power generation, and now there is no relevant procedure about the calculation method of solar thermal power plant auxiliary power rate. In the course of the study, we compared and analyzed the running mode of solar thermal power plant and fossil-fired power plant. Then we found the research result that the calculation method of fossil-fired power plant auxiliary power rate was not applicable to the solar thermal power plant. Based on the analysis respectively of collection field system, heat absorption and transfer system, heat storage system and conventional island system of parabolic trough solar power plant, this paper put forward a calculation method for auxiliary power consumption of parabolic trough power plant. In this paper, a conclusion is drawn that the solar thermal power plant should use long sequence typical year solar radiation value to hourly calculate the typical year's power generation and auxiliary power consumption, and auxiliary power rate is the ration of auxiliary power consumption and power generation. The calculation idea and method of auxiliary power rate of parabolic trough solar power plant can be used as an reference for the tower solar power plant, and it promotes the devolpment of solar thermal power plant design in China.
