On-grid inverters for wind turbines

On-grid inverters for wind turbines are key components that convert the electrical energy generated by wind turbines into a format suitable for the public power grid. These inverters are crucial for feeding electricity into the grid and ensuring energy quality. The main features and functions are:

Conversion of direct current (DC) to alternating current (AC): The inverter converts the direct current generated by the wind turbine into alternating current

that has the same frequency and voltage as the public power grid. This enables seamless feed-in to the grid.

Maximum power point tracking (MPPT): This technology optimizes energy production by continuously adjusting the operating point of the wind turbine to obtain the maximum yield from wind power. This is done by monitoring the current wind conditions and the performance of the turbine.

Network synchronization: On-grid inverters ensure that the energy generated by the inverter is in sync with the power grid. This is crucial for the safety and stability of the power grid and prevents disruptions.

security features: They are equipped with various safety features to ensure safe operation. These include overload protection, overtemperature protection and the ability to interrupt the feed-in in the event of a mains interruption (anti-islanding function).

Monitoring and control: Many on-grid inverters offer built-in monitoring features that allow the wind turbine performance to be tracked in real time. This can be done through an APP or web portal, making it easy to monitor operational data, energy production and system status.

Easy integration: These inverters are designed for integration with various wind turbine and energy management systems, making them easy to adapt to different applications and installation types.

Use as a solar inverter: On-grid inverters can also be used as solar inverters to convert the DC energy generated by solar panels into grid-compatible AC power, making them versatile for both wind and solar energy applications.

Operating options: If desired, the inverter can be operated either with batteries to store excess energy or without batteries to feed the generated electricity directly into the grid. This offers flexibility in energy supply and the use of renewable resources.

On-grid inverters are critical to the efficiency and performance of wind turbines, ensuring that the energy generated can be used effectively and fed into the grid, thus helping to promote renewable energy and reduce dependence on fossil fuels.
