HighVoltage DirectCurrent Transmission

Abstract

This thesis is focused on the application and development of HVDC transmission technology based on thyristor without turn-off capability. Compared with other macroelectronics in the power field, thyristor without turn-off capability has successful operation experience to ensure reliability and high power ratings to transfer bulk energy.This thesis covers converter station design and equipments, reactive power compensation and voltage stability, AC/DC filters design, control strategy and function, fault analysis, overvoltage and insulation co-ordination, overhead line and cable transmission, transmission line environmental effects, earth electrode design and development.W i t h t h e d e v e l o p m e n t o f n e w c o n c e p t s a n d t e c h n i q u e s , t h e c o s t o f H V D C transmission will be reduced substantially, thereby extending the area of application.
