Reactive power is one of the power system ancillary services and can be supplied from either static or dynamic VAR sources. Provision of reactive power in the proximity of load is clearly beneficial for the efficiency of the overall system. Reactive power provision as an ancillary service by the load itself could greatly increase the margin to voltage collapse and, therefore, influence the stability...
This work relates to active power filtering of line-commutated HVDC system using the definitions of active, reactive, and distortion power presented in one of the several power theories. The behavior of the rectifier terminal of a six-pulse, line-commutated, series compensated HVDC system is analyzed for instantaneous power oscillations. Shunt compensation is done based on the power theory under discussion...
