| Abstract |
In this paper a current reference generation
method for a voltage source shunt active power filter is
examined. The proposed method improves the harmonic
filtering by compensating the delays in the system. In
stationary operating point of the load the method uses
measurement data sampled in previous periods to generate a
reference prediction. Since in transient state of the load the
prediction no longer holds true, a computational control delay
compensation algorithm is used in the reference generation
instead of the prediction in this situation. Changing the
algorithm according to the operating point guarantees effective
harmonic compensation in all operating points. In this paper
the system performance is examined with an active filter
simulation model. |
