Efficiency Analysis of 5MW Wind Turbine System in an All-DC Wind Park

Paper i proceeding, 2017

This article presents the efficiency analysis of a 5 MW wind turbine generating system in an all-DC wind park comprising of a permanent magnet assisted synchronous reluctance generator (PMaSynRG) system as well as an IGBT equipped forced-commutated inverter. In this article, the focus is on the NPC converter and DC-DC converter with an optimized high-frequency transformer. The total efficiency through the AD-DC converter to DC-DC converter was found to be 96.72 % as safed operation.
