15:15 Active Damping for Power Quality Improvement in Grid-Connected Current-Controlled Voltage Source Converters
M.Eng. Lorenzo Giuntini, GE Consumer & Industrial, Riazzino, Schweiz
Active damping schemes have known a variety of applications. This paper discusses the benefits of one such scheme when applied to grid-connected voltage source converters. Particularly, it includes experimental results from applying active damping to the front-end rectifier in a double-conversion UPS. The proposed control technique improves input performance both in terms of power factor and current distortion, while ensuring stability and robustness. Actual performance has been verified under sinusoidal as well as distorted grid voltage.
15:15 Harmonic Current Control in DG-Connected Network Using Proposed Pulse Adaptive VSI
M.Sc. Navid Daniali, Euro Engineering, Auerbach i.d.OPf., Deutschland
A new PWM scheme, suitable for being used in DG interface is proposed at this paper. By using proposed pulse adaptation method in conventional voltage-control-based method of DG, current harmonics in network could be compensated without adding to the complication of the main power control level, because this method, unlike the conventional harmonic compensation methods, applies pulse shaping process in PWM level
15:15 Dynamic Performance Evaluation of a dual UPQC Operating Under Power Quality Disturbances
Prof. Dr. Sergio Augusto Oliveira da Silva, Federal University of Technology -Paraná, Cornélio Procopio, Brasilien
This paper presents the dynamic performance evaluation of a 3Ph UPQC deployed to perform the series-parallel connection to electrical system. Since the UPQC operates using a dual compensating strategy, the parallel converter feed the load as a sinusoidal voltage source. Thus, the overall system dynamic is improved because the series converter does not need any direct control to compensate the utility disturbances, as conventionally occurs in the control of UPQCs. The UPQC is subjected to power quality events to evaluate its dynamic behavior.
15:15 Active Filtering of DC Ripple Currents Between Converter and Low-Resistive DC Load
M.Eng. Sebastian Raab, University of Applied Sciences Wuerzburg-Schweinfurt, Bad Neustadt a.d.Saale, Deutschland
This paper introduces a power electronic control element consisting of fast switching SiC MOSFETs for compensating ripple currents emerging when coupling the DC link of aconverter to low-resistive, low-inductive high current load/source like lithium-ion batteries.Those ripple currents cause additional losses and can damage components exposed to it. Using the application presented,packaging dimensions of heavy, costly passive filters can be lowered and thus the losses arising inside them.
15:15 Dynamic Control and Design of a Modular Power Flow Controller for HVDC Networks with Fault Clearing Capabilities
M.Sc. Daniel Dinkel, Universität der Bundeswehr Munich, Neubiberg, Deutschland
Future HVDC networks require an optimized converter topology for control of energy distribution. The proposed converter meets the requirements of connecting any number of transmission lines with different voltage levels and lengths, full control of power distribution and scalability.
15:15 Multi-Terminal HVDC Grid Control Using a Fictitious, Model Based Machine Set
Dipl.-Ing. Steffen Menzel, University of Bremen, Bremen, Deutschland
For future wide area grids, which are needed to make further offshore wind farms accessible, a reliable and stable multi terminal HVDC grid is proposed. Using HVDC avoids the transfer of large amounts of reactive power related to a conventional HVAC grid. This work shows an approach of controlling multiple voltage source converter stations using a fictitious, model based machine set for each converter station. The dynamic behaviour of this multi terminal HVDC system is analysed in simulation.
15:15 Research on Solid State Circuit Breaker Based on SiC MOSFET with Soft Switch off Method
Haihong Qin, Nanjing University of Aeronautics and Astronautics, Nan jing, China
In order to ensure the safe and reliable operation of silicon carbide power devices and
improve the reliability of silicon carbide based DC solid state circuit breakers, the short circuit
capability of silicon and silicon carbide MOSFET is analyzed and compared. In addition,
gate-source voltage clamp methods are elaborated and compared. Combined with
desaturation detection, a "soft turn-off" short-circuit protection method based on source
parasitic inductance is proposed. Finally, a DC solid state circuit breaker prototype is built for
experimental verification. Experimental results show that the proposed method can not only
reduce the voltage stress of the power device, but also suppress the short circuit current.
