Multi-infeed HVDC transient response and recovery strategies

Should two or more DC transmission systems terminate in close electrical proximity in the same AC system, there is the potential for degradation of DC transient performance due to interaction in response to common AC system disturbances. This paper presents the digital simulation of a test system and shows the DC responses to AC faults at various locations. Control strategies are evaluated to enhance the recovery of the DC systems from the disturbances.<
