Catenary Voltage Support: Adopting Modern Locomotives With Active Line-Side Converters

Alfred Rufer, Behrooz Bahrani

This paper proposes a voltage support scheme for traction networks, which compensates for the voltage drop along the catenary line to which locomotives are connected. The proposed method is based on the injection of capacitive reactive power through the cu ...

The performance test and analysis of ITER Main and Correction Busbar conductor

Pierluigi Bruzzone, Boris Stepanov, Yu Wu

The first ITER Main Busbar (MBCN1) and Correction Busbar (CBCN1) conductor samples were manufactured in ASIPP and tested in the SULTAN facility. This paper introduces the sample manufacture, including strand, cabling, jacketing and sample preparation, and ...

On the inter-area optimal voltage and reactive power control

Sidi-Rachid Cherkaoui, Omid Alizadeh Mousavi

Scheduling voltage and reactive power is one of the major problems and concerns of the Transmission System Operators (TSOs) especially after deregulation of power market. Due to locally provision of the reactive power resources, each TSO has developed its ...

Haptic Tactile Interface (HTI): Design of the Power Supply Stage

Yves Perriard, Christophe Winter

The driving electronics of an haptic tactile interface (HTI) is presented. The stability of its linear power amplifier under the capacitive load of the HTI piezoelectric actuator is analysed and ensured. As the HTI actuator is a resonant one, a topology to ...

Optimization-Based Voltage Support in Traction Networks Using Active Line-Side Converters

Alfred Rufer, Behrooz Bahrani

Low system voltage in traction networks, mainly caused by active power absorption of locomotives, adversely affects the performance of the locomotives and also the power transmission capability of the catenary line. This paper introduces a voltage support ...

Advanced Control Strategies for Voltage Source Converters in Microgrids and Traction Networks

Behrooz Bahrani

Increasing concerns regarding global warming caused by greenhouse gases, which are mainly generated by conventional energy resources, e.g., fossil fuels, have created significant interest for the research and development in the field of renewable energies. ...

Modular DC/DC Converter for DC Distribution and Collection Networks

Stephan Kenzelmann

A major change in the electrical transmission and distribution system is taking place in Europe at the moment. The shift from a centralised energy production to a distributed generation profoundly changes the behaviour of the grid. Environmental or social ...

A new approach to plasma profile control in ITER

Jonathan Bryan Lister, Sun Hee Kim

Advanced tokamak operation in ITER, such as the steady-state and hybrid modes, requires an active realtime feedback control of plasma profiles to achieve the advanced regimes for sustained operation. In this work, we have explored a potentially robust cont ...
