A New Method of Reference Signals Calculation for Switching Compensator
Abstract: The switching
compensation devices, such as active power filters and static var generator,
are growing rapidly for power quality improvement. The current reference
signals is one of the important factor affecting the responsible speed and
compensation effect. In this paper, a new strategy for reference signals
calculation is present based on Current’s Physical Components. Through the
orthogonal decomposition of the load current by the CPC power theory, the
reference current, for various compensation objectives of switching
compensation devices, can be calculated by the combination of the orthogonal
current components. It is demonstrated that this strategy can be used for
various compensation goals of limited switching compensation devices and
changing the compensation objectives on-line according to the power grids. The
validity of the developed strategy is verified by the simulation results.
