Abstract
The conventional converter consumes reactive power by virtue of the lagging power factor inherent in normal operation. Operation at leading power factor requires commutation in the region (α+ <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">u</sub> ) > π. This can be achieved through artificial commutation by reversing the valve-to-valve voltage during the commutation period. In a two-converter station the vars so generated can be supplied to a conventional converter operating in parallel on the ac side and, ideally, the station capacitive reactance can be reduced to that required for satisfactory harmonic filtering.
