   Active Damping of Resonance Oscillations in LCL-Filters Based on Virtual Flux and Virtual resistor
By GULLVIK William; NILSEN Roy; NORUM Lars [View]
[Download]

Abstract: This paper presents several methods for active damping of resonance oscillations in LCL-filters. All the methods are implemented using only estimated values of the capacitor voltages and currents. The sensorless control strategy used in this paper is based on the virtual flux concept and all voltages and currents with the exception of the dc bus voltage and the converter output currents are derived from the virtual flux. The presented theory is then verified experimentally in the lab.

   Control of series compensated induction motor using magnetic energy recovery switch

Abstract: This paper proposes a induction motor drive using magnetic energy recovery switch (MERS). The MERS is a series compensation device and it can control the load voltage and input power factor. Stability problem because of self-excitation was found. However, this could be solved with voltage feedback control. Small scale experiments and field test results are reported.

   Distributed Generation Power Inverters as Shunt Active Power Filters for Loss Minimization in the Distribution Network
By BELTRAN Hector; BELENGUER Enrique; APARICIO Nestor [View]
[Download]

Abstract: This paper evaluates the benefits that can be achieved in the operation of LV distribution networks with a large penetration of distributed generation when the inverters that interface with the network are used as shunt active power filters to reduce the zero sequence current component generated by unbalanced loads. For that purpose, a typical urban distribution network has been simulated and several inverters have been connected to the network. A current control mode has been implemented for the inverters so any current component in the system can be compensated or filtered. The reduction in the power losses and the increase in the voltage quality have been quantified for the network
