Enhancement of the overall system dynamic performance of an existing ac/dc scheme is possible by minor modifications in the NVDC controls. The paper presents some control modifications for the Chateauguay HVDC back-to-back 1000 MW scheme with interconnections to the Beauharnois generators and to the 765 kV intertie to NYPA. These modifications lead to a remarkable improvement in the damping of ac voltage and tieline power oscillations under heavy loading conditions. Voltage instability following disturbances under very weak ac system conditions can also be avoided.
