Polaris solar PV net news: January 7, China Meteorological Administration, China wind energy solar energy resources Center for 2016 year Bulletin of wind and solar resources. Bulletin points out that in 2016 as the national average wind speed of 10 meters height normal with slightly bigger times, years terrestrial surface average surface radiation exposure and best slightly smaller beveled normal radiation radiation year year. Cold waves and strong cold air just slightly more frequency is the main reason behind national average wind speed slightly; the national average number of rainy days than usual about 6.1% is the high amount of solar radiation reaching the surface to reduce one of the reasons.
“Look at the 2016 wind and solar resources compared with the first 10 years of change and its spatial distribution, can be used as wind and solar power plants objective evaluation of the 2016 generation production base. “Wind and solar resources, said Shen Yanbo, Vice Director of the Center.
Wind and solar Resource Center, national meteorological station 2004-2016 surface observational data, statistical analysis in China in 2016 10 m height wind speeds on land features, come in 2016, the national annual average wind speed is 10 meters above the ground height nearly 10 years (2004-2013) are large value 0.68%, which is the normal slightly bigger times, but uneven distribution of regional differences. Most of the provinces (autonomous regions and municipalities) winds near year-round average, Shanghai, Jiangsu, Zhejiang, Shandong and Hainan in 5 provinces (municipalities) annual average wind speed is small 5%, Ningxia, Chongqing, Heilongjiang is larger 5%.
It is learnt that, in 2016, most of the provinces (autonomous regions and municipalities) land 70 meters height the average annual wind speed is close to the average annual value, smaller areas are Shanghai, Jiangsu, Shandong, Hainan 4 provinces (municipalities), large areas are Chongqing, Guangxi, Shanxi, Heilongjiang, Sichuan, Shaanxi, Hubei, 7 provinces (autonomous regions and municipalities).
2015 and 2016 compared to annual average wind speed in addition to Hainan, Tibet and its mean annual wind power density is slightly reduced and other provinces (autonomous regions, municipalities) have varying degrees of increase in national land 70 metres high mean annual wind power density of more than 150 Watts/square meter area, 65% area is larger than the perennial, 35% area is smaller than the perennial.
Meanwhile, wind and solar resource centre 2004-2016 of the yearly national meteorological station radiation and daylight observations, assessment: in 2016, the national level of terrestrial surface average total annual radiation of 1478.2 millions of kWh/m, than in the last 10 years (2004-2013) less average 22.5 kilowatt hours per square metre, relatively low 1.5%, and 2015. Regional solar energy resources are quite different, on the whole, less rain and dry plateau region, Plains, rain and high humidity areas of small features.
“2016 effect of cold air 15 times, 5 times less than the average, cold waves and strong cold air is 2.5 times more than the average, North of the Huai River region more cold air cold and 1.7 times, South of the Huai River region more cold air cold and 0.8 times, China’s average wind speed is slightly larger. “Shen Yanbo said.
