In order to constantly improve the output characteristics of wind turbines, the HIL (Hardware Inthe Loop) experimental platform of wind turbines is built to optimize control.According to the product parameters of 1.5 MW direct‐drive PMSG (PermanentMagnet Synchronous wind Generator) of Dongfang Electric Corporation (DEC), thesimulation model of wind turbine is built in RTDS (Real Time Digital Simulator),and optimised by comparing with the wind speed–power curve of products, thesimulation model of wind turbine with engineering accuracy can be obtained. Baseon the engineering model and actual controller of products, the HIL experimentalplatform of wind turbines is built to optimise control. In the case ofunbalanced or asymmetrical grid voltage, in order to make the wind turbineoutput be stable, the DDSOGI‐PLL (direct Decoupling Double Second‐OrderGeneralized Integral Phase‐Locked Loop) is proposed to improve the performanceof PLL, the active/reactive current decoupling algorithm based on positive andnegative sequence voltage orientation respectively is proposed to eliminate thenegative sequence current to maintain a constant output power. The effectivenessof algorithm is verified by the HIL experimental platform, the active poweroutput of wind turbine remains constant, the grid‐connected adaptability of windturbines is improved significantly.
