A dc link for the power system simulator

Abstract

High Voltage Direct Current (HVDC) links are used for bulk power transmission due to its advantages over the alternating current (ac) transmission. A HVDC link between India and Sri Lanka has also being proposed. Hence it is a timely needfor the students in local universitiesto be able to study the behaviour of HVDC transmission. This paper presents the design of a DC link for a locally assembled Power System Simulator as a teaching tool.The objective is to use this design as a learning tool to study the behaviour of HVDC transmission under normal and abnormal operation. It is expected to be used for laboratory experiments related to HVDC transmission and Power Electronics, hence providing the opportunity for visualization of the behaviour of performance parameters at the significant points of the model.
