云南季节性水电产生原因及时空分布

The Causes and Spatial and Temporal Distribution of Seasonal Hydro-electricity in Yunnan Province

介绍"十二五"中后期,云南省金沙江中下游水电集中投产,云南水电装机容量和占省内电源装机比重迅速增加。由于新增水电调节性能较差,加之金中直流等配套送出工程推迟投产,导致云南丰水期出现大量季节性水电盈余。对云南季节性水电产生的原因进行了深入分析,并对"十二五"末期云南季节性水电的时空分布进行了测算,为消纳云南季节性水电提供参考。

In the mid and late“the 12th 5-year”,with the large hydropower stations on the middle and lower reaches of jinsha river put into production,the capacity and proportion of hydropower increasing dramatically？ On one hand the regulation performance of the new hydropower station is very poor,on the other hand the jinzhong DC delivery projects delayed,these result in a large number of seasonal hydro-electricity in flood season in Yunnan Province？ To provide a reference for Yunnan hydropower utilization,in this paper,the cause of seasonal hydro-electricity in yunnan are analyzed,and the spatial and temporal distribution of seasonal hydro-e-lectricity in Yunnan was calculated.
