[Abstract]:In recent years, the research on transmission of offshore wind power through frequency-divided transmission lines has attracted much attention both at home and abroad. From the wind turbine units based on PMSG (permanent Magnet Direct Drive synchronous Generator) which remove the converter at the end of the machine, The sub-frequency offshore wind power system composed of submarine cable and AC / AC converter can capture wind energy by controlling the speed of PMSG through the AC-AC converter at the end of the line, which can save the initial investment and operation and maintenance cost. Considering the influence of transformer and transmission line, The quasi steady state model of frequency division offshore wind power system is derived, the design principle of multi machine vector controller based on rotor mean flux orientation is given, the method of solving the operating frequency of multi unit is given from the angle of curve fitting, and the four PMSG as an example, The simulation model of frequency division offshore wind power system is built. The results show that the speed of wind turbine unit can follow the instruction value under different wind speed conditions by using multi-machine vector control method and realize the optimal capture of wind energy.
