Research on offshore DC wind power circuit

This paper studies the offshore DC wind power technology, to explore how to reasonably transmit and use the electrical energy generated by the offshore wind generator, to obtain a more optimized circuit model of offshore DC wind power technology. This paper mainly discusses the process of voltage conversion, inverter, rectification and output of appropriate three-phase AC voltage in the process of ac transmission from HVDC offshore wind turbine. According to the “π” equivalent circuit principle, the paper compares HVDC transmission mode with HVDC transmission mode, and compares the harmonic distortion rate of unipolar modulation and bipolar modulation in pulse width modulation through analog circuit, determines the final circuit model and obtains the simulation result diagram.
