wind generator deming customized 5kw10kw grid-connected controller wind power generation grid-connected converter inverter

introduction to grid-connected wind power generation system

fan grid-connected power generation system consists of fan, fan grid-connected controller, grid-connected inverter, metering device and power distribution system. the wind energy is converted into ac power through the fan, converted into dc power by the fan grid-connected controller, and then converted into ac power with the same frequency and phase as the grid through the grid-connected inverter, part of the power supply is provided to the local load, and the remaining power is fed into the power grid.

grid-connected wind generator controller performance characteristics

*this product is produced according to industry standard jb/t6939.1-2004 and national standard gb/t19115.1-2003. it can also be produced according to users' technical requirements.

*color touch screen display. the operation status of the controller is displayed visually. abundant data show: real-time fan voltage, current, solar panel voltage, current, dc output voltage, current, cumulative power generation.

*the technical parameters of the controller can be adjusted through the touch screen. the control parameters can be adjusted for different wind turbines.

*two sets of control systems are adopted, pwm constant voltage and constant current system + three-phase braking system.

*current control, wind speed control and wind turbine speed control can be added, and control parameters can be set.

*in the case of strong wind and strong wind, the controller is constant voltage and stable output current, providing dc constant voltage power supply to ensure the normal operation of the inverter.

*when the grid-connected inverter is disconnected, the controller outputs constant voltage and waits for the inverter to resume its work.

*when the power grid is cut off, the controller controls the fan braking. when the power grid is restored, the controller stops braking, the fan resumes operation, and the inverter resumes grid connection.

*lightning protector is provided inside the controller. limit the instantaneous overvoltage entering the power line of the wind turbine to the voltage range that the equipment or system can bear, or drain the strong lightning flow into the ground to protect the equipment from being damaged by lightning impact.

*the controller has an emergency stop switch. in case of emergency, press the emergency stop button on the front panel. all power supply of the controller is cut off, and the wind generator is immediately braked.

*the controller has manual brake switch, which can be used by users according to the situation. with this switch, the wind generator will be forced to brake.

*modbus communication protocol is adopted. it is convenient for customers to carry out secondary development.

*supports communication methods such as rs485, wifi, gprs, and ethernet. you can monitor the working status of the grid-connected wind power generation system in real time through the pc or mobile terminal, or query the historical working status. the mobile terminal is compatible with android and os. all data can be connected to the internet of things.

*solar panel control system can be added according to customer requirements.

*according to the type of wind turbine, the controller can increase various braking control functions such as yawing control, pitch control, mechanical tail folding control, mechanical brake, hydraulic brake, electromagnetic brake, etc.

performance characteristics of fan grid-connected inverter

*the main circuit adopts the dsp chip produced by ti company in the united states, infineon igbt module, and the drive protection is infineon movement, which is safe and reliable;

*using spwm pulse width modulation technology, pure sine wave output, automatic synchronous tracking with power grid, power factor close to 1, low current harmonic content, no pollution to public power grid, no impact;

*wind input maximum power tracking technology (mppt);

*the power curve of the fan can be set. the default value is 30 fan curve setting points.

*closed-loop control of inverter grid-connected current, controllable and adjustable;

*wide input ac voltage range, suitable for different occasions;

*frequency disturbance detection technology to realize anti-island control;

*it has all-round power protection scheme and perfect self-detection and protection functions. in case of system failure, grid-connected inverter will be stopped;

*compact circuit structure, maximum efficiency> 98%;

*the protection level can reach ip65;

*supports communication methods such as rs485, wifi, gprs, and ethernet. you can monitor the working status of the grid-connected wind power generation system in real time through the pc or mobile terminal, or query the historical working status. the mobile terminal is compatible with android and ios. all data can be connected to the internet of things.
