El sistema de aerogenerador conectado a la red se compone de aerogenerador, controlador conectado a la red, inversor conectado a la red, dispositivo de medición y sistema de distribución de energía. El aerogenerador convierte la energía eólica en energía eléctrica de CA, el regulador de red la transforma en energía eléctrica de CC y el inversor de red convierte la energía eléctrica de CC en energía eléctrica de CA de la misma frecuencia y fase que la red. La energía sobrante se inyecta en la red.
Características de funcionamiento de los inversores de aerogeneradores conectados a la red

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)
