alternative coefficient meaning in Chinese
选择系数
Examples
- The adopted alternative coefficient for capacity is from 1 . 05 to 1 . 10 and for electric generation 1 . 05 . in fact , the capacity benefits are related to maximum load , load curve and the weight of hydropower power capacity . while the benefits of coal consumption saving are related to load consumption characteristic and power structure in addition to maximum load and load curve of the power system
当系统的水电(含抽水蓄能)比重较小时， 1 . 05 1 . 1容量替代系数可能偏小；而当抽水蓄能电站占有一定比重时，这种方法又可能过高地估计了抽水蓄能电站的容量效益，因为它未能考虑某些月份抽水蓄能电站可能出现的空闲容量。 - Static benefits are generated from peaking and valley - filling , which are further divided into capacity benefits and coal saving benefits . dynamic benefits come from its fast starting and flexible operation , including frequency regulation , synchronous condenser operation , fast coverage of steep load gradient and synchronous spinning reserve . as for the calculation of static benefits of pumped storage plant , the alternative coefficient method is normally adopted at present
目前在抽水蓄能电站的静态效益计算中，一般采用替代系数法，即用抽水蓄能电站的装机容量乘以容量替代系数( 1 . 05 1 . 1 )计算抽水蓄能电站的替代容量；用抽水蓄能电站的发电量乘以电量替代系数( 1 . 05 )计算替代电站的发电量，再根据循环效率的大小计算抽水蓄能电站的燃料消耗。
