Traditional electric trains have a low power factor, high loading variation change and inefficiency, generating both negative sequence current and the imaginary part of positive sequence current. Delta type Load Balancer associated with specially connected transformers is generally adopted to correct power factor and voltage imbalance. However, the modern trains used in High Speed Railway (HSR) have a power factor approximately close to unity, and therefore only need voltage imbalance correction. This study presents novel Load Balancer schemes, which are a modification of the Delta-type Load Balancer, with various connected transformers to correct imbalance. The symmetric component method is also adopted to determine the installation capacity of the proposed Load Balancer schemes.

Keywords: High Speed Railway; HSR; voltage imbalance; voltage unbalanced
