Description
Summary:To enhance the electricity grid's capacity of resource allocation, long-distance, large capacity (Ultra) high-voltage DC transmission technology is widely used. Significantly increased voltage and current levels affect both electric and thermal characteristics of the thyristors in a DC converter valve. This paper aims to establish a thyristor electro-thermal model to analyze the interaction between electrical and thermal stresses under various steady and transient operation conditions. Thyristor junction temperature prediction method was investigated to ensure its long-term reliability in applications.
