Feasibility Assessment of a New Ultra-High Voltage Silicon Carbide Thyristor Technology for Multi-Megawatt Wind Turbines' Power Electronics Converters

Zagres开发了超高压碳化硅（UHV SiC）晶闸管技术的新设计和制造技术，可大幅降低制造成本，高达40%，并在行业中从未使用过的额定电压和频率下运行。该技术已在实验室样机中得到验证，有望应用于多种大功率系统，如可再生能源发电、高压直流（HVDC）系统和灵活交流传输系统（FACTS）。主要的好处包括降低能源成本，提高效率和可靠性。该项目的目的是评估特高压SiC晶闸管技术用于风力涡轮机应用的可行性，并量化其在能源成本、可靠性和效率方面的效益。一个20千瓦的原型转换器将被制造出来，然后在一个真正的风力涡轮机上进行为期三个月的测试。此外，将开发模型来评估用于多兆瓦风力涡轮机的特高压SiC晶闸管变流器的优势。

Zagres has developed new design and fabrication techniques for Ultra-High Voltage Silicon Carbide (UHV SiC) Thyristor technology which enables substantial reduction in manufactuing costs, as much as 40%, and operation at voltage and frequency ratings which have never utilised before in the industry. The technology, proven on laboratory prototypes, promises applications in several high-power systems, such as renewable energy generation, High Voltage DC (HVDC) systems and Flexible AC Transmission Systems (FACTS). The key benefits include reduction in cost of energy and enhancement in efficiency and reliability. The aim of this project is to assess the feasibility of the UHV SiC Thyristor technology for wind turbine applications and quantify their benefits with respect to cost of energy, reliability and efficiency. A prototype 20 kW converter will be built and then tested on a real wind turbine for a three-month period. In addition, models will be developed to evaluate the advantages of UHV SiC Thyristor converters for multi-MW wind turbines.
