On grid wind turbine inverter performance characteristics
(1) The main circuit uses the DSP chip produced by the American TI company, German Infineon
IGBT module, drive protection is the Japanese Mitsubishi movement, and the on grid output part
use isolation transformer, which is safe and reliable;
(2) Using SPWM pulse width modulation technology, pure sine wave output, automatic synchronous
tracking with the grid, power factor close to 1, low current harmonic content, no pollution to the grid,
no impact;
(3) Wind turbine input maximum power tracking technology (MPPT)
(4) The power curve of the wind turbine can be set, the default is 20 points, and the internal
expansion is 50
(5) 7-inch color touch screen display, system operation data and fault information at a glance,
and convenient parameter setting;
(6) On grid inverter current closed-loop control, controllable and adjustable;
(7) The input DC voltage range is wide, adapt to the needs of different occasions;
(8) Frequency disturbance detection technology to realize anti-island control;
(9) The comprehensive power protection scheme and perfect self-detection and protection functions
will stop the on grid inverter when a system failure occurs.
(10) Circuit structure is compact, the maximum efficiency≥98%
(11) Support RS485, WiFi, GPRS, Ethernet and other communication methods. You can monitor the
working status of the on grid wind power generation system in real time through the PC or mobile
phone, and you can also query the historical working status. The mobile terminal is compatible with
Android and IOS. All data can be connected to the Internet of Things.
