Abstract
Opening and closing is the key of floodgate control and application. Scientific and reasonable con-
trol scheme, to achieve the best flood diversion effect and ensure gate security, has very important
significance. According to the 1998 and 2003 flood process data of Li river of Jinshi hydrological
station, through the same frequency control amplifier, design flood process is obtained. The sche-
duling scheme is evaluated, and results show that, the existing scheduling scheme of flood diver-
sion effect is not good. Floodgate optimization objective function has been established. On the ba-
sis of the objective function, with a frequency of 5% of the designed flood hydrograph for example,
a floodgate optimization control scheme has been developed. Analysis shows that the floodgate
control scheme can achieve better flood diversion effect and safety.
