In the same wave-energy power generation controller 106, wave energy generating set of the rectifier 1061 for will be connected The alternating current of 101 outputs is converted to direct current, and by alternating current transmission made of conversion to chopper 1062;Chopper 1062 is used Voltage adjustment is carried out in the direct current transmitted to the rectifier 1061 connected, forms the direct current with predeterminated voltage grade, And the DC power transmission with predeterminated voltage grade will be formed by accumulator 103 by DC bus 107.
Since wave energy generating set is alternating current using electric energy caused by wave energy, in order to by power storage to electric power storage Chi Zhong needs alternating current being converted to direct current, therefore the alternating current of wave energy generating set output is whole firstly the need of being transferred to It flows device and carries out rectification, to obtain direct current.Since alternating current caused by wave energy generating set is by with higher voltage, Direct current made of correspondingly being converted by rectifier also has higher voltage, and carries out charging to accumulator and need lower electricity Pressure, it is therefore desirable to copped wave processing be carried out to the direct current that rectifier exports by chopper, there is predeterminated voltage grade to obtain Direct current, meet the requirement charged to accumulator.
For example, the rated output voltage of each wave energy generating set is 690V, wave energy generating set is by the friendship of 690V After galvanic electricity is transferred to rectifier, the alternating current of 690V is switched to the direct current of 800V by rectifier, and rectifier is by the direct current of 800V It is transferred to chopper.After the direct current of 800V is adjusted to the direct current of 240V by chopper, and by DC bus by 240V's DC power transmission is to accumulator, to charge to accumulator.
For each wave energy generating set be arranged one include rectifier and chopper wave-energy power generation control Device, wave-energy power generation controller can be converted to the alternating current that wave energy generating set exports steadily and with predeterminated voltage etc. The direct current of grade, to be charged to accumulator by converting the direct current obtained, guarantee charges to accumulator reliable Property, and ensure the safety of accumulator.
