【摘要】 传统双馈风电机组并网后，系统惯量降低易导致系统在小干扰情况下频率、电压波动较大，针对该问题提出一种基于模糊的主动支撑型双馈风电机组自适应惯量阻尼控制策略。首先，基于传统虚拟同步发电机控制，在功率同步环节引入一阶暂态电动势方程作为励磁控制器，提高风电机组对系统有功、无功的支撑能力。然后，通过分析双馈风机在暂态过程中的功频运行特性，并结合模糊自适应惯量阻尼控制策略，实时调整虚拟惯量和阻尼以降低频率偏移。最后，在MATLAB/Simulink中以WSCC9总线系统为基础，以风电场代替3号发电机进行仿真，验证了所提控制策略的有效性及可行性。更多还原

【Abstract】 The reduction of system inertia after grid connection of traditional doubly-fed wind turbine easily leads to large frequency and voltage fluctuations of the system under small disturbances, and a fuzzy-based adaptive inertia damping control strategy of active-supported doubly-fed wind turbine is proposed to deal with this problem.Firstly, based on the traditional virtual synchronous generator control, the first-order transient potential equation is introduced into the power synchronization link as the excitation controller to improve the support ability of the wind turbine for the active and reactive power of the system; then, by analyzing the power-frequency operation characteristics of the doubly-fed wind turbine in the transient process and combining with a fuzzy adaptive inertia damping control strategy, the virtual inertia and damping can be adjusted in real time to reduce the frequency deviation. Finally, the effectiveness and feasibility of the proposed control strategy are verified by simulation in MATLAB/Simulink with a wind farm instead of generator No. 3 based on the WSCC9 bus system.更多还原
