摘要：
For series-parallel topology wind farm, adopting traditional maximum power point tracking (MPPT) control strategy will lead to over voltage and over modulation when the wind turbines in same series branch under different wind speeds. To solve this problem, the paper investigates the operation characteristics of series-parallel direct-drive permanent magnet synchronous generator(D-PMSG) wind farm based on voltage source converter-high voltage direct current (VSC-HVDC), and a power-voltage coordination control strategy suitable for series and parallel topology MPPT is proposed. In addition, the upper limit of DC voltage was quantitatively analyzed, which ensured the system operates within an upper and low voltage limit in any operation states. The result of simulation proved the method can achieve the purpose of maximum wind power capture in a safe range. © 2017, Harbin University of Science and Technology Publication. All right reserved.
