Abstract

Geothermal energy is a kind of clean and renewable energy with huge resources. Geothermal power generation is a form of efficient utilization of geothermal energy. There is a big gap between the installed capacity of geothermal power generation and the new installed capacity of 500MW in the 13th five year plan. The unclear price mechanism of geothermal power generation is an important reason hindering the development of geothermal power generation. The efficiency of geothermal power generation is relatively low, and the theoretical research and technology of geothermal power generation need to be innovated. In this paper, the empirical correlation of evaporation temperature is obtained based on the cycle splitting method, and the calculation software of electric heating performance of geothermal power generation is developed. The comparison with the actual index of power station shows that the error is less than 10%. Compared with the traditional method, the calculation method based on cycle splitting method is more rapid and convenient, and the accuracy rate is more than 95%.
