Product Description

Product Description

On Grid Wind Turbine System

The On Grid Wind Turbine System, developed by Jinan Deming Power Equipment Co., Ltd, is a comprehensive solution for harnessing wind energy and integrating it into the electrical grid. This system consists of a wind turbine, on grid controller, on grid inverter, metering device, and power distribution system.

With this system, wind energy is efficiently converted into AC electrical energy by the wind turbine. The on grid controller then converts this energy into DC electrical energy, ensuring optimal performance. The DC electrical energy is further converted into AC electrical energy of the same frequency and phase as the grid by the on grid inverter.

One of the key advantages of the On Grid Wind Turbine System is its ability to supply power to the local load. A portion of the converted energy is directly supplied to the local load, ensuring uninterrupted power supply. Additionally, any surplus power generated by the system is fed back into the grid, contributing to the overall energy supply.

Performance Characteristics of the On Grid Wind Turbine Inverter

The on grid wind turbine inverter, a crucial component of this system, offers exceptional performance characteristics. It efficiently converts DC electrical energy into AC electrical energy, ensuring seamless integration with the grid. This inverter is designed to maintain the same frequency and phase as the grid, enabling smooth power transmission.

By utilizing the On Grid Wind Turbine System, you can harness the power of wind energy and contribute to a sustainable future. Experience reliable and efficient electricity generation with this innovative solution from Jinan Deming Power Equipment Co., Ltd.

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 a high-quality product that meets the JB/T6939.1-2004 industrial standard and GB/T 19115.1-2003 national standard. It is designed to fulfill users' technical requirements, ensuring optimal performance and safety.

Key Features:

1. 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 case of power outage.


2. Two Sets of Control Systems: The controller offers two sets of control systems - PWM constant voltage system and three-phase brake system. This ensures efficient and safe operation of the wind turbine.


3. PWM Constant Voltage Control: The controller's PWM constant voltage control is set at 120% of the rated power of the wind turbine. If the PWM's capacity is exceeded, the brake will automatically start to prevent any damage. After 10-20 minutes, the brake will stop, and the wind turbine will resume power supply, ensuring the safe running of the overall wind turbine generation system.


4. DC Constant Voltage Output: The controller can conduct DC constant voltage output during strong or super-strong winds, ensuring the safe running of the inverter.


5. Grid Power Resumption: In case of grid power outage, the controller will stop the inverter's output to the grid. The three-phase dump load of the controller will automatically start, putting the wind turbine on braking status. Once grid power resumes, the controller will stop the three-phase dump load, allowing the wind turbine and inverter to resume normal operation.


6. Surge Arrester: The controller is equipped with a surge arrester to protect the equipment from lightning shock damage. It limits instantaneous overvoltage into the wind generator within the controller or system's bearable voltage range.


7. Emergency Stop and Manual Brake: The controller features an emergency stop switch for cutting off all power supply in case of emergencies. It also has a manual brake switch for forcibly braking the wind turbine.


8. Modbus Communication Protocol: The controller adopts the Modbus communication protocol, allowing for convenient development by customers.


9. Technical Parameter Adjustment: The controller's technical parameters can be adjusted through the RS485 interface, providing convenience for professional customers to adjust different wind turbines.


10. Monitoring and Compatibility: The controller supports WIFI and GPRS, enabling customers to monitor the working status of the grid-tie wind power system in real-time through PC or mobile terminals. The mobile terminal is compatible with Android and IOS.


11. Additional Features: The controller can be equipped with a solar panel control system, mechanical yawing, furled empennage, and various brake functions based on customers' demands.

On Grid Wind Turbine Inverter

The On Grid Wind Turbine Inverter, manufactured by Jinan Deming Power Equipment Co., Ltd, is a reliable and efficient product designed to work seamlessly with the wind turbine controller. Its key features include:

1. High-Quality Components: The main circuit of the inverter uses the DSP chip produced by the American TI company, German Infineon IGBT module, and drive protection from the Japanese Mitsubishi movement. The on-grid output part is equipped with an isolation transformer, ensuring safety and reliability.


2. Pure Sine Wave Output: The inverter utilizes SPWM pulse width modulation technology to achieve a pure sine wave output. It automatically synchronizes with the grid, resulting in a power factor close to 1 and low current harmonic content. This ensures no pollution or impact on the grid.


3. Maximum Power Tracking Technology: The inverter incorporates wind turbine input maximum power tracking technology (MPPT), optimizing the power output of the wind turbine.


4. Power Curve Setting: The power curve of the wind turbine can be set, with the default being 20 points. The internal expansion allows for up to 50 points, providing flexibility and customization options.
