| 目的 对凉山州某地太阳能热发电站拟选场址的太阳能资源进行评估。方法 利用环境气象因素监测设备监测太阳直接辐射、总辐射和温湿度等环境气象因素，采用经验公式估算凉山州某地全年太阳直接辐射和总辐射量，并利用实测值进行验证。结果 某地在秋冬之交，直接辐射强度的平均值为5.7 kW•h/(m2•d)，总辐射强度的平均值为5.1 kW•h/(m2•d)。结论 某地为太阳能资源很丰富地区，全年太阳直接辐射量大于5000 MJ/m2，全年太阳总辐射量大于6000 MJ/m2，2月、3月、4月和5月为太阳能热发电最佳经济运行的月份。在秋冬之交，有利因素为70%以上的天数直接辐射强度都大于经济性运行的直接辐射强度指标，利于太阳能热发电，是潜在的太阳能热发电站候选地区；不利因素为多云天气和阴天占总天数的百分比接近50%，会极大地影响太阳能热发电的发电量和发电效率。 |

| 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. |
