New synchronous compensators for the Nelson River HVDC system-planning requirements and specification

For the first units of the Limestone Generating Station on the Lower Nelson River in northern Manitoba, scheduled to come into service in the fall of 1990, additional VAR compensation equipment is required at the inverter end of the Nelson River HVDC system to accommodate power from Limestone. The authors describe the system requirements of and the overall specification for the synchronous compensators selected to supply the reactive power and voltage support. The purpose of the synchronous compensators is to optimize power delivery by the DC links. Proper specification of parameters for synchronous compensators applied at the terminal of a DC link ensures that the compensators will provide support to the operation of the DC system.<
