Abstract
A direct-drive wind farm parameter tuning method and system considering the interaction between generators are provided. The method includes: collecting initial oscillation current of each direct-drive wind turbine port in the direct-drive wind farm; according to collected data, taking period of dominant oscillation mode as the iteration period to calculate the overall farm-grid interaction dynamic energy and parameter tuning index of the direct-drive wind farm in current iteration period; obtaining stability level of the direct-drive wind farm based on the overall farm-grid interaction dynamic energy in the current iteration period; when the system is unstable, the optimization model of key control parameters is established with the minimum value of the parameter tuning index in the current iteration period as the objective function and the range of each key control parameters as the constraint condition to achieve the key control parameters tuning of the direct-drive wind farm.
