| Abstract: |
| Objective To evaluate solar energy resource for site selection of solar thermal power plant in somewhere of Liangshan Prefecture. Methods Environmental and meteorological factors such as direct radiation and total radiation, temperature, humidity, etc. were monitored according to monitoring equipment. The direct radiation and total radiation in the whole year in somewhere of Liangshan Prefecture were calculated with empirical formula and verified with measured values. Results The average solar direct radiation was 5.7 kW•h/(m2•d) and the average total radiation was 5.1 kW•h/(m2•d) when autumn turned into winter. Conclusion Solar energy resource in the region is rich. The direct radiation in the whole year exceeds 5000 MJ/m2, and the annual total radiation is larger than 6000 MJ/m2. Its optimum and economic operating mouths last from February to May. When autumn turns into winter, direct radiation strength of above 70% of days is higher than the index for direct radiation strength of economic operation. It is favorable for solar thermal power generation. It is a candidate area for potential solar thermal power plant. The unfavorable factor is that it has nearly 50% of cloudy days, which reduces capacity and efficiency of solar thermal power generation. |
