Comparison and Selection of High-voltage Large-capacity D-STATCOM Main Circuit

摘要：

In view of analysis and comparison of present high-voltage large-capacity D-STATCOM circuit structure,especially advantages and disadvantages of Δ-cascaded structure and Y-cascaded structure,then it proposes and describes a Y-cascaded structure,the link of which is composed of two back-to-back H converters. Current compensation algorithm based on coordinate αβ conversion,fault links bypass tolerance,and its correlative CPS-SPWM are proposed respectively,the experimental results of 1.14kV/100kVA prototype testify the validity and the effectivity of the proposed structure and algorithm.
