SCADA systems represent a challenging scenario where the management of critical alarms is crucial. Their response to these alarms should be efficient and fast in order to mitigate or contain undesired effects. This work presents a mechanism, the Adaptive Assignment Manager (AAM), that will aid to react to incidences in a more efficient way by dynamically assigning alarms to the most suitable hu...

This paper presents a novel way of generating the reference currents for an active filter and/or a static compensator. A compensator structure is proposed which is capable of balancing an unbalanced delta-connected load that may also draw harmonic currents. In addition to balancing the load, the supply side power factor is also made unity. The theory of instantaneous symmetrical components is u...

This letter describes an alternative solution to passive and active filter arrangements on the dc side of the converter. The circuits of dc-side ripple elimination are based on direct reinjection of the ripple in series with the dc line.

ABSTRACT A new current-mode universal active-RC filter is proposed. The proposed circuit is based on a new universal passive filter topology. Two Fully Differential Current Conveyors (FDCCII) are used to construct a universal active-RC filter from this passive filter. The FDCCII based proposed filter has only grounded resistances and capacitors as the passive elements. The circuit simultaneousl...

A new universal current mode filter circuit composed by three multi-output second generation current conveyor circuits (MOCCII), two controlled active resistances and two passive capacitors is presented. This filter can realize all the five standard filter functions, namely low pass, band pass, high pass, notch and all pass, without changing the circuit topology. TSPICE simulation using 0.18 μm...

-This paper deals with the active power filter design controlled by using hysteresis technique. The genetic algorithm is used to design the controllers to minimize the %THD of the source current. The results are compared with that designed from Ingram and Round approach. The simulation results confirm that the genetic algorithm can provide the minimum %THD of the source current compared with th...

The first part of this thesis contains a literature study of current tuning techniques for continuous-time integrated filters. These tuning methods are characterised by which quantity they measure, their dependence on certain characteristics of the input signal, or matching of components on chip. The structure of the different tuning schemes are explained. The merits and drawbacks as well as ac...

It is shown that allpole filters of secondand third-order can be significantly desensitized to component tolerances by so-called impedance tapering, i.e., successively impedance-scaling upwards the Lsections of a resistance–capacitance ladder network in the forward and feedback path of a single-amplifier active filter. In order to obtain a realizable filter, certain constraints on the design eq...
