RT21 | [Chinese] Research and Application of key technologies for grid-friendly wind turbines

This presentation will talk about adaptive technology of grid-connection in scale: establish the wind turbine output impedance model, put forward the low-frequency impedance control optimization technology, inhibiting the ultra/subsynchronous oscillation during large-scale connection to the weak power grid; Research and application of power grid-friendly key technologies for wind turbines: a. Fault voltage crossing technology for wind turbines; b. Subsynchronous oscillation suppression technology of wind turbine cluster's connection to weak power grid; c. Broadband oscillation supperssion technology of Wind turbine cluster's connection to flexible UHV grid.
