| 1 | 大型输水渠道运行仿真系统控制周期选取显示文摘为了提高大型输水渠道运行仿真计算的精度、稳定性及速度,建立了大型输水渠道自动化运行仿真模型,研究了PID控制器参数及控制周期变化对渠道系统动态响应的影响,并对实际工程等体积及下游常水位运行方式下的系列工况进行了仿真计算.结果表明:为了获得较好的系统控制效果,PID控制器比例系数需随控制周期的增加而增大,并通过PID参数寻优给出了两者之间的定量关系;控制周期增加后,渠道的响应时间增长,而模型的计算时间缩短,控制设备的操作减少.综合考虑渠道系统的控制效果及闸门设备的控制操作,取仿真模型的控制周期为15~30min较适宜. | 丁志良 余启辉 杨哲江 | 2010 | 河海大学学报(自然科学版)2010，38，6： | 2 |
| 2 | Research on Controlled Volume Operation Method of Large-scale Water Transfer Canal显示文摘The controlled volume method of operation is especially suitable for large-scale water delivery canal system with complex operation requirements.An operating simulation model based on the storage volume control method for multi-reach canal system in series was established.In allusion to the deficiency of existing controlled volume algorithm,the improved controlled volume algorithm of the whole canal pools was proposed,and the simulation results indicated that the storage volume and water level of each canal pool could be accurately controlled after the improved algorithm had been adopted.However,for some typical discharge demand operating conditions,if the previously mentioned algorithm was adopted,then it certainly would cause some unnecessary gate adjustments,and consequently the disturbed canal pools would be increased.Therefore,the idea of controlled volume operation method of continuous canal pools was proposed,and corresponding algorithm was designed.Through simulating practical project,the results indicated that the new controlled volume algorithm proposed for typical operating conditions could comparatively and obviously reduce the number of regulated check gates and disturb canal pools for some typical discharge demand operating conditions,thus the control efficiency of canal system could be improved. | DING Zhiliang WANG Changde XU Duo XIAO Hua | 2011 | Journal of Northeast Agricultural University(English Edition)2011，18，3： | 0 |
