Product Description
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
On Grid Wind Turbine Controller
1. The product is manufactured according to the JB/T6939.1-2004 industrial standard and GB/T 19115.1-2003 national standard,and also with users’ technical requirements.
2. Big LCD Display. The graphics visually show the working status of controller. Abundant data display: real-time wind turbine voltage, current, power; dc output voltage, current, accumulative total generating electricity (The main-board is with battery, in the case of power off, history data can be stored for 30 days.)
3. Two sets of control systems:PWM constant voltage system and three phase brake system.
4. PWM constant voltage control is 120% of the rated power of the wind turbine. In case exceeding of PWM’s capacity, the brake will automatically start immediately. After 10-20 minutes, the brake will stop and the wind turbine will re-start to resume power supply to ensure the safe running of overall wind turbine generation system.
5. When strong or super-strong wind, the controller can conduct DC constant voltage output to ensure the inverter safe running.
6. When disconnected grid-connected inverter, the controller can conduct DC constant voltage output and wait for inverter resume to work.
7. When grid power is off, the inverter stops output to grid power, three-phase dump load of controller will automatically start, and wind turbine will be on braking status. When grid power resumes, the controller will stop three-phase dump load, wind turbine will resume to run, and inverter will resume to supply grid power.
8. The inside of controller is equipped with surge arrester. Limit instantaneous over voltage into wind generator within the controller or system bearable voltage range, or conduct the strong lightening current into earth to protect the equipment from lightning shock damage.
9. The controller is equipped with emergency stop switch; in case of emergency, press down the emergency stop button in the front panel to cut off all power supply of the controller and the wind turbine will immediately brake.(Please do not press this button in non-emergency situations.)
10. The controller is equipped with manual brake switch. when using this switch, the wind turbine will carry out brake forcibly.
11. Adopt Modbus communication protocol. It is convenient for customers to develop again.(optional)
12. Ajust controller technical parameters, through RS485 interface. It is convenient for professional customers to adjust different wind turbines.(optional)
13. Support WIFI and GPRS. Customer can monitor the working status of grid-tie wind power system in real time through PC or mobile terminal, or check historical working status. Mobile terminal is compatible with Android and IOS. (optional)
14. Solar panel control system can be added according to customers’ demand.(optional)
15. For different wind turbines type, the controller can be equipped with mechanical yawing, furled empennage, mechanical or hydraulic, pneumatic, electric magnetic and other brake functions.(optional)
On Grid Wind Turbine Inverter
(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.
