摘要
潮汐电站的水头随潮位变化迅速,水轮机需长期在较大的水头范围内运行。额定水头作为水轮机的重要参数之一,其选择会直接影响电站的水头保证率,进而会影响年发电量经济指标。以国内某单库单向运行潮汐电站为基础,建立了发电量计算模型,利用Matlab软件进行了水库水位曲线模拟及电站年发电量计算,研究单库单向运行潮汐电站额定水头选择与发电量的内在关系,为电站经济效益分析提供数据依据。
The head of a tidal power station changes rapidly with the tidal level,and the hydraulic turbine should operate in a large water head range for a long period.As one of the important parameters of hydraulic turbines,the choice of rated head will directly affect the head guarantee rate of power station,which will further affect annual economic indicators.Based on a unidirectional single-reservoir tidal power station in China,the generating capacity calculation model is established to study the intrinsic relationship between rated head selection and generating capacity of station.The model has function of reservoir water level curve simulation and annual generation capacity calculation by using Matlab,which can provide data basis for economic benefit analysis of tidal power station.
