针对汽轮机冷端系统运行优化传统方法存在不能实时反映机组实际运行情况的问题,提出一种便捷的基于机组运行历史数据的智能方法.该方法首先通过BP神经网络的多参数输人来预测机组的净功率及背压,同时利用遗传算法(GA)优化神经网络...展开更多 针对汽轮机冷端系统运行优化传统方法存在不能实时反映机组实际运行情况的问题,提出一种便捷的基于机组运行历史数据的智能方法.该方法首先通过BP神经网络的多参数输人来预测机组的净功率及背压,同时利用遗传算法(GA)优化神经网络模型来提升预测结果的精度,然后改变循环水流量进行净功最大寻优,得出净功最大时的循环水流量及汽轮机运行背压.通过对某630MW...

A convenient intelligent method based on historical data of unit operation is proposed to address the issue of traditional methods for optimizing the operation of the cold end system of steam turbines that can't reflect the actual operation of the unit in real time....MORE A convenient intelligent method based on historical data of unit operation is proposed to address the issue of traditional methods for optimizing the operation of the cold end system of steam turbines that can't reflect the actual operation of the unit in real time.The proposed method first predicts the net power and back pr...
