This industrial-grade controller seamlessly transitions between grid-connected and standalone operation while precisely regulating wind turbine performance through its advanced pitch control mechanism. With a power handling capacity of 200kW, it meets the demands of utility-scale renewable projects, remote microgrids, and industrial facilities requiring reliable off-grid power. The pitch control system, certified to EN ISO 13849-1 PLd, ensures safe and efficient turbine operation by adjusting rotor blade angles within milliseconds of wind speed changes .
The controller optimizes power flow between wind turbines, solar PV systems, energy storage, and the grid (when available). Its advanced algorithm balances generation and demand, prioritizing renewable sources while maintaining stable frequency and voltage in off-grid mode. The system supports 200kW continuous output with peak handling up to 250kW during transient conditions.
Featuring a 3-phase, 400V AC pitch drive with output currents up to 350A for 3 seconds, the controller adjusts blade angles with exceptional precision . This rapid response capability maximizes energy capture during variable winds and initiates safety shutdowns within 2 seconds of detecting critical conditions, preventing turbine damage during extreme weather.
In grid-connected mode, the controller provides LVRT compliance to support utility grid stability during voltage fluctuations . In off-grid operation, it manages battery storage systems and backup generators, ensuring uninterrupted power supply to critical loads even during extended renewable energy lulls.
Housed in a rugged IP65 enclosure, the controller operates in extreme temperatures from -30°C to +70°C, making it suitable for onshore and offshore wind-solar hybrid installations . Redundant power supplies and communication interfaces ensure system availability exceeding 99.9%.
Energy developers utilize this controller to integrate large wind turbines (1.5MW+) and solar arrays, creating hybrid power plants with higher capacity factors and more consistent output than single-source renewable projects.
Off-grid mining sites leverage the system’s high power capacity and pitch control to reduce diesel consumption, powering crushers, processing equipment, and camp facilities with renewable energy.
Isolated communities and resort islands utilize the hybrid controller to achieve energy independence, combining wind and solar generation with storage to replace expensive diesel generators while maintaining reliable power.
The pitch control system is certified to EN ISO 13849-1 Performance Level d (PLd), ensuring it can safely execute emergency shutdowns even if primary control systems fail . It also meets IEC 61400 wind turbine safety standards.
During grid outages, the controller automatically transitions to off-grid mode within 200ms, maintaining power supply through stored energy and continued renewable generation. The pitch controller adjusts turbine output to match load demands without grid support.
Industrial communication protocols including Profinet, EtherCAT, and CANopen enable integration with SCADA systems . Secure VPN connectivity allows remote monitoring and control, essential for large-scale projects in remote locations.
The system includes predictive maintenance algorithms that monitor pitch drive health and lubrication status. Routine inspections are recommended every 6 months, with major service intervals at 5-year increments, aligning with wind turbine maintenance schedules.
NE-GT (Grid-tie) model On grid Wind Turbine Controller Product Characteristics
1.The product is manufactured according the JB/T6939.1-2004 industrial standard and GB/T 19115.1-2003 national standard also with users’ technical requirements.
2.Big LCD display.The images tell working state visually.Various data show: real-time wind turbine voltage,current,solar panel voltage,current,DC output voltage,current,total power generation(The main board is with button battery,in case of power failure, history data can be saved for 30 days).
3.Two sets of control systems：PWM constant voltage system and three-phase dump load system.
4.PWM constant voltage control is 120% of the rated power of the wind turbine. In case exceeding of PWM’s capacity, the three-phase dump load will automatically start immediately. After 10-20 minutes, the three-phase dump load will stop and the wind turbine will re-start to resume power supply to ensure the safe running of the overall wind turbine generation system.
5.When the strong or super-strong wind conditions, the controller can conduct constant voltage output to ensure the inverter safety running.
6.When the condition of disconnected grid-connected inverter, the controller can conduct constant voltage output and wait for inverter resumption.
7.When the grid is cut off, the three-phase dump load of the controller will automatically start to work and the inverter will stop output to grid. When the grid resuming, the controller stops three-phase dump load and the inverter will resume power supply.
8.The inside of the controller is equipped with surge protector. Contain the over voltage into the wind turbine under the bearable voltage of the equipment or system. On another way, to conduct the strong lightening current into the earth directly to avoid any damage of equipment.
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（three-phase dump load).
10.The controller is equipped with manual three-phase dump load switch. To using this switch, the wind turbine will brake (three-phase dump load).
