Outline of Research Activity in the HVDC Systems

摘要

The use of HVDC lines in electric power transmission is increasing all over the world. This exceptional increase is the result of the rapid technological development in AC/DC converter stations (power electronics) and of the advantage of HVDC over AC transmission on long distances, submarine connection by means of cables, interconnection of different electric systems, easy control of flowing power, etc. Consequently, also the research and testing activities in this field are under worldwide development. However, research activities imply huge investments and the involvment of a lot of personnel. Cooperation agreements such as the one between CESI and CPRI could permit the combination of efforts and the optimization of the results. In this framework, an RandD cooperation program is on going between the CPRI and CESI (Italy) research facilities. In this paper, the facilities available at CESI for carrying out research and tests in the HVDC field are presented and outlines of some studies and tests, already performed, are given. Furthermore, a review of the joint research work which is being carried out by CESI and CPRI is reported. (ERA citation 14:017320)
