FAQS
Q
What problems does the GT-PCTC controller solve in the wind grid-tied market?
Compared with standard PV grid-tied inverters, small wind turbine grid-tied inverters face several issues:
- Few professional small wind turbine grid-tied inverter factories.
- High cost, often several times more expensive than PV inverters.
- Unstable quality and lack of after-sales service.
- Low operating efficiency.
- No grid connection certification.
Q
How does the GT-PCTC controller work with mainstream PV inverters?
The controller tracks and controls the grid-tied power in real time. It monitors the generator speed and operates according to a user-configured wind turbine power curve (Speed vs. Power) configured directly on the touch screen, allowing standard PV inverters to run according to the wind turbine's actual performance.
Q
How does the system's protection mechanism operate during overspeed?
The system features a dual protection mechanism:
- PWM Constant Voltage: Controls the wind turbine output so it does not exceed 120% of its rated power.
- Three-Phase Dump Load Brake: If the wind turbine overspeeds and exceeds the PWM capacity, the three-phase dump load system automatically and immediately brakes the turbine. The brake releases after 10-20 minutes, allowing the turbine to restart.
Q
What happens to the turbine when the utility grid is cut off or the inverter disconnects?
- Grid Cut-off: The three-phase dump load automatically brakes the wind turbine and stops the inverter from outputting to the grid. Once the grid recovers, the controller recovers the wind turbine.
- Inverter Disconnection: The controller conducts constant voltage output and holds safely until the inverter resumes operation.
Q
What standard hardware safety switches are built into the controller?
- Surge Protector: Limits transient over-voltage or discharges powerful lightning currents into the ground to protect the equipment.
- Emergency Stop Switch: Cuts off all power to the controller and immediately engages the three-phase dump load brake.
- Manual Brake Switch: Keeps the wind turbine locked in a braked state continuously using the three-phase dump load.
Q
What optional communication protocols and remote monitoring features are available?
- Modbus Protocol & RS485: Available for secondary development and parameter adjustments.
- WIFI & LAN Remote Monitoring: Allows real-time and historical monitoring via PC or mobile applications (compatible with both Android and iOS).
