Delta’s state-of-the-art wind power converter solutions leverages our core competence in high-efficiency power electronics to support our customers’ megawatt-level wind power plants in key regions of the world such as Europe, China and Africa.
- Excitation controller is integrated in the converter
- Excitation controller, as part of the converter, communicates to the main controller at the turbine
- Inlet of excitation controller passing through the space reserved for main cable enables easy connection
- Excitation system providing redundant design ensures high reliability
- Using nonlinear resistance to reduce the lead time of excitation suppression
- AC power input is available for commissioning and maintenance
- Output filters reduce excitation winding dv/dt
- Built-in cooling design provides a total solution combining converter and cooling system
Fundamental
- The electrically excited synchronous generator is connected directly to the generator-side of the converter, while the rotor excitation is provided by excitation controller which is equipped with the converter. All the power is transmitted to the grid through the converter. The converter tracks the frequency and phases of grid voltage to keep the output current and frequency of turbines in consistent with those of the grid
System Architecture
- A converter contains 1 to 3 sub-converter systems, depending on the power level required by the system. Each sub-converter system further contains a generator-side converter and a grid-side converter"
