二小一贫矿床,其矿体平均厚度(〈5m)在薄一极薄矿体之间,均属难采矿体,采矿的贫化率极高,一般都在30%以上,最高可达60.70%。对这些矿开发利用时,一定要进行可行性论证和试生产验证,确保开发利用有利可图。

We describe a specific approach to capacity man a ge ment for distribution grids. Based on simulations, it has been found that by curtailing a maximum of 5% of the yearly energy production on a per-generator basis, distribution grid connection capacity can be doubled. We also present the setting and fi rst results of a fi eld test for validating the approach in a rural distribution grid in northern Germany. 展开更多
