Abstract

The invention provides a method for estimating annual energy production of a tidal current energy power generation device, which comprises the following steps of S1, finding a corresponding relation between a tidal current flow velocity value and an output electric power value of a tidal current energy power generation device by utilizing field test data; S2, collecting historical data, and counting the distribution condition of the tidal current flow velocity of the tested sea area within the time range of one year; and S3, calculating the annual average power generation power of the tested tidal current energy power generation device. According to the method for estimating the annual energy output of the tidal current energy power generation device, the actual situation that the tidal current flow velocity of a tested sea area is not the same every month is considered as a whole, and the annual average distribution frequency of the tidal current flow velocity of the tested sea area in each flow velocity interval is counted by adopting a mathematical statistics method; therefore, the method for estimating the annual energy output of the tidal current energy power generation device is optimized, and errors are greatly reduced.

Description

technical field [0001] The invention belongs to the field of on-site testing of a tidal current energy generating device, in particular to a method for estimating the annual power generation of a tidal current energy generating device. Background technique [0002] At present, the estimation of the annual power generation of the tidal current energy generation device is mainly carried out according to the following steps, [0003] 1. Test data processing [0004] During the field test, on the one hand, the on-site test equipment obtains the output voltage, current and other parameters of the tidal current energy generation device, and then can calculate the electric power parameters output by the tidal current energy generation device; Power flow parameters in the installation. Then, the electric power value at the same moment is one-to-one corresponding to the flow velocity value input into the tidal current energy generating device, and the interval method is used to pro...
