Abstract

The invention discloses a variable-current power transmission system of a tidal current generator unit, and a working method thereof; the variable-current power transmission system comprises a plurality of water-turbine generator sets which are respectively and sequentially connected with a corresponding electric reactor and a three-phase full-controlled rectifier; an output end of each three-phase full-controlled rectifier is respectively connected with a storage battery and a three-phase full-controlled inverter; a back-to-back structure is formed by each three-phase full-controlled rectifier and each three-phase full-controlled inverter; and an output end of each three-phase full-controlled inverter is connected with an electrical load by an inductance filter and an alternating-current transformer. The three-phase controlled rectifier adopts a three-phase full-controlled space vector pulse width modulation (SVPWM) rectifier, and the invention has the advantages of reducing the number of devices on a carrier platform, simplifying the system and reducing the consumption.

Description

technical field [0001] The invention relates to the technical field of offshore power generation, in particular to a tidal current generating set conversion power transmission system and a working method. Background technique [0002] Offshore power generation systems in the prior art, such as offshore wind power, usually use AC-DC-AC conversion technology for each generator to convert electric energy into high-voltage alternating current, and then carry out power transmission. The number of electrical equipment is large. In addition, the offshore carrier platform The large load leads to a large scale of the platform, which increases the complexity of the entire system and the construction cost of the system. The existing tidal current power generation system mostly adopts the generator output directly through the submarine cable transmission mode, the output voltage is low, and the loss of the transmission line is large. Moreover, the existing tidal current power generatio...
