| 摘 要： | 对全数字仿真自动发电控制系统的优化效果进行了分析,用微增率连续性和极小值的定义证明了生成解的极小值特性,并用2种不同的优化方式取得了相同的组态效率.结果表明:在某一水头下,给定水电站内并联运行机组的流量或出力,有且只有唯一极至效率,即最优组态效率.

| Abstract: | The optimization result of full-digital control system for power generation is analyzed,the minimality of generated solution is justified by using the continuity of micro-incrementary ratio and definition of minimum,and an identical configuration efficiency is obtained by means of two different optimization methods.The result shows that,under a definite head,there is only a unique maximal efficiency for given flow and output of parallelly operating units in hydropower stations,i.e.there is an optimal configuration efficiency. |
