1. What are the main components of an on-grid wind turbine system?
The system consists of a wind turbine, an on-grid controller, an on-grid inverter, a metering device, and a power distribution system. The controller converts AC power from the turbine to DC, which the inverter then converts to synchronized AC power for the grid.
2. How does the MPPT technology benefit wind power generation?
Maximum Power Point Tracking (MPPT) dynamically adjusts to wind variation to ensure the wind turbine operates at its peak efficiency, maximizing the electrical energy harvested from the wind.
3. What communication options are available for monitoring?
The system supports multiple options including RS485, WiFi, GPRS, and Ethernet. Users can monitor system status and historical records in real-time using a PC or a mobile app compatible with Android and iOS.
4. What protections are integrated into the system during failures?
The inverter features extensive protection configurations, including over-voltage protection, grid disconnection protection, regulated supply output, surge arrester, and anti-islanding control, automatically shutting down the system when a failure occurs.
5. Is it possible to customize the turbine's power curve?
Yes, the power curve of the wind turbine is fully configurable. By default, it is set with 20 points, and the internal expansion can support up to 50 points to fit specific turbine parameters.
6. Can the controller and dump load handle harsh environments?
Yes, the system is designed to work in temperature conditions ranging from -30°C to 60°C. Depending on configuration, it offers IP20 indoor protection or IP65 outdoor protection to withstand diverse weather conditions.
