摘要進行了潮汐彎道段電廠取排水模型試驗，採用w形波紋凹槽方式加糙，使模型糙率達到了模型試驗的要求。It makes the deduction on design tidal level process more reasonable than ever. finally, taking into account the observed data of tidal level are much more integrated than observed data of tidal discharge and the correlative relationship are established based on large numbers of samples. then, the sub stage maximum tidal discharges and tidal velocities are obtained according to the regressive equations and the observed tidal level, and the sub stage design maximum tidal discharges and tidal velocities are estimated by way of frequency analysis
最後，針對橋位河段實測潮流資料短缺而潮位資料相對完整的實際情況，基於大量樣本建立了潮流量與潮汐要素的相關關系，利用實測長系列潮位資料得到分期最大潮流量、潮流速系列，經頻率分析確定了分期設計最大潮流量、潮流速。Harmonic method : the representation of tidal variations as a sum of harmonics known as constituents each of different frequency, amplitude and phase
調和法：將潮汐變化分解為不同頻率，振幅和相位角的諧波（即分潮）的方法。This paper firstly introduces the phylogeny and actuality of tide - power stations ; the development style of them ; and then, establishes the mathematics model of optimal regulation of tide - power stations ; narrates how to use eq, dynamic programming, genetic algorithm to solve the problem of optimal regulation of tide - power stations individually ; makes comparison of three kinds of methods, pointing out the excellence and weakness of each method ; discusses some particular problems of tide - power stations, differing from normal water power stations. besides, this paper uses vb to develop an optimal regulation software which can be used in all tide - power stations
本論文首先介紹了世界潮汐電站的發展史及發展現狀；潮汐電站的建庫方案；然後建立潮汐電站廠內經濟運行和短期優化調度的數學模型；在此基礎上，進一步使用等微增率法、動態規劃法和基因遺傳演算法來求解潮汐電站優化調度問題，並對三種方法作了比較，指出各自的優缺點；論文也探討了潮汐電站優化調度中不同於常規水電站優化調度的特殊問題的處理方法。Based on the morphological characteristics of riverbed of tidal estuaries, a calculation formula for the widening rate of the estuarine regulation line is derived
