Research on the Upgrade and Transformation Plan of Huarui SL1500 Wind Turbine Inverter
This paper analyzes the main technical difficulties and solutions for the technical transformation of the inverter,and proposes a series of solutions,aiming at the design capacity limitation of the protected unit of the upper inverter,which cannot meet the new power grid standards such as high voltage crossing and sub-synchronous resonance oscillation suppression,and the inability of the upper design to realize the necessary hardware upgrade due to the space limitation of the engine room.The detailed design,implementation and effect evaluation are carried out.Through the research of this paper,it can provide a certain reference and reference for the technical reform of up-down converter,which has certain research significance and practical application value.
