Abstract

The invention discloses a direct current collection system of a wave power generation device and a control method and system of the direct current collection system, the direct current collection system comprises n sub-modules, and each sub-module comprises two half-bridge modules and a high-frequency inductor. The low-voltage sides of the sub-modules in the direct-current current collection system are dispersed and can be independently connected to the wave energy generator set; the high-voltage side sub-modules are connected in series and connected with a high-voltage direct-current network, high-voltage electric energy transmission is achieved, and the construction cost of the converter and the network structure thereof is effectively reduced. The invention further provides a control method and system of the direct-current current collection system, and series decoupling, independent control, power bidirectional flow and self-adaptive control of the wave energy generator set of the high-voltage side submodules are achieved. Therefore, the technical problems of poor stability and high cost in the prior art are solved.

Description

technical field [0001] The present application relates to the field of electric power technology, and in particular to a DC current collection system of a wave energy generating device and a control method and system thereof. Background technique [0002] Wave energy is a rich renewable marine resource with a series of characteristics such as large storage capacity, wide distribution space, and no pollution. Under the development background of "carbon peaking and carbon neutrality", the use of wave energy to generate electricity has broad applications prospect. The array floater wave energy power generation can absorb wave energy in different positions continuously and evenly by arranging multiple oscillating floats in an orderly array in a certain sea area, which better meets the requirements of large-scale and large-scale power generation. At present, it is an important direction for the research and development of large-scale wave energy generation devices. [0003] At ...
