Active power control For the fan, active power control includes active power rate control and maximum active power output control. Goldwind MW series direct drive fan can not only achieve smooth control of maximum output active power and active power change rate of the fan, control accuracy of 100kW/s or even more accurate, response speed is tentatively set to 1s according to requirements, and can be received and automatically Perform active power control signals from the power dispatching department (including start and stop control of the fan).

In the process of limiting the output power of the fan, it is also possible to dynamically estimate and upload the active output capability of the fan at that time. In the case of short-circuit faults of the power grid, the active power is proportionally output according to the residual voltage of the fan terminal, which contributes to the stability of the grid frequency. With the self-developed wind farm energy management platform, the smooth and rapid control of the active power output of the wind farm is realized. The frequency detection sampling frequency is 0.1ms, and the grid frequency can be accurately determined within 1ms to meet the grid requirements.

Model and parameter direct drive fans can provide dynamic models of fans based on BPA, PSS/E, DigSILENT, PSLF and other software to adapt to the global wind turbine market. The solution to the grid problem faced by wind turbines is recommended around the grid situation and grid problems that wind turbines are facing, combined with the development experience of “connected network friendly” of direct-drive wind turbines, strengthening “system awareness” for wind farms, “system awareness” "Already an integral part of the big grid system. For some regional power grids, wind power is already an important source.
