Paralleling and deparalleling tests on Nelson River HVDC Bipoles 1 and 2
This paper reports on low-voltage (+ or - 150 kV) paralleling and deparalleling tests on the Nelson River HVDC bipoles 1 and 2 performed in the summer of 1982 as preparation to the final high-voltage (+ or - 463.5 kV) tests after completion of Bipole 2. The control system developed for paralleling, parallel operation, and deparalleling of bipoles 1 and 2 has been described in an earlier paper. The present paper provides additional information on these controls with respect to the control system hierarchy, telecommunication requirements and the hardware, especially the new hardware installed in Bipole 1 controls. System aspects of paralleling and special considerations for these low-voltage tests are also discussed. The significance of these low-voltage tests lies in the fact that for the first time two HVDC bipoles were paralleled and deparalleled using high-voltage high-speed switches, the system being unique in the sense that Bipole 1 uses mercury arc valves while Bipole 2 comprises second generation thyristor valves. Since the Nelson River scheme has rectifiers remote from each other and a control system that could allow paralleling of remote inverters, this parallel operation is a simple form of multiterminal operation.
