Adaptive Multi-Mode Power Control for Direct-Drive Permanent Magnet Synchronous Generator under Microgrid
摘要
Abstract
While in a microgrid,the wind turbine generator is required to work in both maximum power point tracking and fixed power point tracking modes,and it must change the mode properly.Aiming at this problem,an adaptive multi-mode power control for direct-drive permanent magnet synchronous motor (PMSG) in a microgrid has been proposed.The control strategy combined with field oriented control was applied to a PMSG and two-level full power back-to-back converter drive system.The objective of the control strategy was to make the wind turbine operating in the maximum power point tracking mode or tracking performance enhancement mode of non-maximum power point tracking.Compared to the conventional variable-step hill climbing search algorithm,the novel control was faster,and the robustness was stronger.The novel control has a fast dynamic response to the change of the power command and the environment,and has an accurate steady-state response as well.Finally,based on the low power direct-drive PMSG test platform,some tests have been done to verify the validity of the new proposed method.关键词
