Product Description

Product Description

On Grid Wind Turbine System

The On Grid Wind Turbine System, designed and manufactured by Jinan Deming Power Equipment Co., Ltd, is a reliable and efficient solution for harnessing wind energy. This system consists of a wind turbine, on grid controller, on grid inverter, metering device, and power distribution system.

With the On Grid Wind Turbine System, wind energy is effortlessly converted into AC electrical energy by the wind turbine. The on grid controller then converts this energy into DC electrical energy, which is further transformed into AC electrical energy of the same frequency and phase as the grid by the on grid inverter. This ensures seamless integration with the existing power grid.

One of the key advantages of the On Grid Wind Turbine System is its ability to supply power to the local load. This means that a portion of the generated energy is directly utilized by the local electrical system, reducing dependency on external sources. Additionally, any surplus power is seamlessly fed back into the grid, allowing for efficient utilization and potential cost savings.

Performance Characteristics:

• Efficient conversion of wind energy into AC electrical energy


• Seamless integration with the existing power grid


• Supplies power to the local load, reducing dependency on external sources


• Surplus power is fed back into the grid for efficient utilization

On Grid Wind Turbine Controller

On Grid Wind Turbine Controller

The On Grid Wind Turbine Controller, manufactured by Jinan Deming Power Equipment Co., Ltd, is designed to meet the JB/T6939.1-2004 industrial standard and GB/T 19115.1-2003 national standard, as well as users' technical requirements.

Features:

• Big LCD Display: The controller features a large LCD display that visually shows the working status of the wind turbine. It provides abundant data display, including real-time wind turbine voltage, current, power, as well as DC output voltage, current, and accumulative total generating electricity. The main-board is equipped with a battery, allowing history data to be stored for 30 days even in the case of power off.


• Two Sets of Control Systems: The controller offers two sets of control systems, including PWM constant voltage system and three-phase brake system.


• PWM Constant Voltage Control: The controller ensures the safe running of the wind turbine generation system by providing PWM constant voltage control at 120% of the rated power of the wind turbine. In case of exceeding PWM's capacity, the brake will automatically start, and after 10-20 minutes, the brake will stop and the wind turbine will re-start to resume power supply.


• DC Constant Voltage Output: The controller can conduct DC constant voltage output during strong or super-strong wind conditions to ensure the safe running of the inverter.


• Grid Power Off Protection: When the grid power is off, the controller stops the inverter's output to the grid power, activates the three-phase dump load, and puts the wind turbine on braking status. Once the grid power resumes, the controller stops the three-phase dump load, the wind turbine resumes running, and the inverter resumes supplying grid power.


• Surge Arrester: The inside of the controller is equipped with a surge arrester to protect the equipment from lightning shock damage by limiting instantaneous overvoltage into the wind generator within the controller or system bearable voltage range.


• Emergency Stop Switch: The controller is equipped with an emergency stop switch for cutting off all power supply of the controller and immediately braking the wind turbine in case of emergencies.


• Manual Brake Switch: The controller features a manual brake switch for forcibly braking the wind turbine.


• Modbus Communication Protocol: The controller adopts the Modbus communication protocol, providing convenience for customers to develop further.


• Adjustable Technical Parameters: The controller allows for the adjustment of technical parameters through the RS485 interface, providing convenience for professional customers to adjust different wind turbines.


• Monitoring and Control: The controller supports WIFI and GPRS, allowing customers to monitor the working status of the grid-tie wind power system in real-time through a PC or mobile terminal. It is also possible to check historical working status. The mobile terminal is compatible with Android and iOS.


• Solar Panel Control System: The controller can be equipped with a solar panel control system according to customers' demand.


• Brake Functions: The controller can be equipped with various brake functions, such as mechanical yawing, furled empennage, mechanical or hydraulic, pneumatic, electric magnetic, and more, to suit different wind turbine types.
