Harmonic resonance problems can be aroused in the industrial power system in the presence of both nonlinear loads and shunt capacitors. This paper investigates the harmonic resonance problem by case-studying of a copper smelting plant low voltage power distribution system. A flexible selective harmonic compensation and resonance damping algorithm for shunt active power filter (SAPF) is proposed to...
In many real-time systems, tasks may experience suspension delays when they block to access shared resources or interact with external devices such as I/O. It is known that such suspensions delays may negatively impact schedulability. Particularly in hard real-time systems, a few negative results exist on analyzing the schedulability of such systems, even for very restricted suspending task models...
This paper concentrates on a new high-order output filter, named LLCL filter, and its application issues on the three-phase three-wire shunt active power filter (SAPF). The LLCL topology is constructed by replacing the capacitor of the traditional LCL filter with an LC branch that resonant at the switching frequency. The SAPF with an LLCL filter exhibits excellent switching frequency harmonic attenuation...
In this paper, the harmonic compensation characteristics of APFs to nonlinear loads are investigated by a circuit equivalent method based on impedance analysis. It is found that the ac-side harmonic current of voltage source type nonlinear load (VSNL) will be amplified seriously when it is compensated by shunt APF, and the ac-side harmonic voltage of current source type nonlinear load (CSNL) will...
