Frequency Regulation Control Strategy for Direct-drive Wind Power Systems Considering Continuous Frequency Drop
摘要
Abstract
In response to the potential frequency secondary drop problem of direct-drive wind power systems in the scenario of continuous frequency drop faults in the power grid,the principle of primary frequency regulation of direct-drive wind power systems was analyzed.A primary frequency regulation control strategy for direct-drive wind power systems was proposed based on the product and difference combination of frequency change rates at pre-and post-sampling times.According to the established criteria,the droop coefficient of the direct-drive wind power system in different frequency response stages was adjusted by comprehensively considering the fan speed,frequency deviation,and frequency rate of convergence,to realize the active frequency support and flexible frequency modulation exit of the wind power system.A simulation model of a direct-drive wind power system was established in Matlab/Simulink to verify the effectiveness of the proposed control strategy.关键词
