Background

1KW 2KW 3KW Grid Tie Wind Generator Inverter With CE Certification

The On grid wind turbine system is composed of wind turbine, on grid controller, on grid inverter, metering device, and power distribution system. Wind energy is converted into AC electrical energy by the wind turbine, and then converted into DC electrical energy by the on grid controller, and then DC electrical energy is converted into AC electrical energy of the same frequency and phase as the grid by the on grid inverter, and part of the power is supplied to the local load. Surplus power is fed into the grid.

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.
