Performance testing of the Sandy Pond HVDC converter

Results of several performance tests for the 1800 MW Sandy Pond HVDC converter terminal are presented and discussed. The work included tests for power line carrier interference, audible sound, AC and DC line faults, and DC harmonic performance. The testing was conducted as part of the commissioning program for the first stage of the Quebec-New England Phase II multiterminal system. During the testing period, Radisson (Quebec) was operating as a rectifier and Sand Pond (New England) operated as an inverter. As expected, the performance testing discovered areas where corrective action was required.>
