In this study, a wind energy conversion system is designed using a three-phase permanent magnet synchronous generator, a six-diode bridge rectifier, a DC–DC boost converter, an inverter, and a load. The proposed inverter is a Packed U-Cell-based multilevel inverter having five or seven voltage levels at the output.
To meet grid compliance standards, inverters in off-grid wind power systems must be designed to produce clean, steady power that matches the grid’s voltage and frequency. This involves a range of technical features, such as phase-locking, frequency-locking, and voltage-matching capabilities.
The switching frequency of the multilevel inverter is set to 4 kHz, and a generator with rated power of 700 W is selected. The output voltage of the generator is varied between 25 V and 35 V through an induction motor. This varying voltage is increased to 45 V using a DC–DC boost converter.
Inverters can support multiple turbines in a single system, allowing for efficient and scalable power generation. This feature is particularly beneficial for large-scale wind farms, where multiple turbines can be connected to a single inverter to maximize power output and reduce costs.
Our standardized solar power and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
