Abstract :
This paper studies dynamic aspects of HVDC system operation with long DC cables. The eigenvalue analysis of CIGRE HVDC system with extended DC cable is presented. It is concluded that significant aggravation in the system stability is present with cables of 1000 km and the system dynamic instability is expected at frequencies 2 Hz\n\n\t\t
