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

Zagres为超高压碳化硅（UHV SiC）晶闸管技术开发了新的设计和制造技术，该技术可大幅降低封装成本，最多可达40%，并可在行业内从未使用过的电压和频率额定值下运行。该技术已在实验室原型上得到验证，有望应用于多个大功率系统，如可再生能源发电、高压直流（HVDC）系统和灵活交流输电系统（FACTS）。主要效益包括降低能源成本及提高效率及可靠性。该项目的目的是评估特高压碳化硅晶闸管技术在风力涡轮机应用中的可行性，并量化其在能源成本、可靠性和效率方面的优势。一个原型20千瓦的转换器将建立，然后测试一个真实的风力涡轮机为期三个月。此外，还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.
