Considerations of AC-System Impacts when Planning Hvdc Systems

摘要

High voltage direct current power transmission systems are operational or under construction at twenty-five locations around the world. In addition, a considerable number are now being carefully examined by utility system planners in this country. Applications include the importing of surplus Canadian energy, regional asynchronous interconnections, and increased utilization of available corridor widths. The objective of this paper is to set forth the identification of the effects of a planned dc system on interconnected ac systems located in the general vicinity. Topics include an introduction to the characteristics and equipment of hvdc systems, considerations at the interface between the ac and dc systems, and some ordinary and extraordinary planning considerations. The paper is intended to provide utility transmission and distributin engineers and system planners with an insight into some of the system-related effects of hvdc systems. (ERA citation 08:002082)
