Thyristor-controlled series capacitors (TCSC) have dynamic characteristics that differ drastically from conventional series capacitors especially at frequencies outside the operating frequency range. Therefore suitable models are needed to properly s

Hip circumference has been shown to be inversely associated with mortality. Muscle atrophy in the gluteofemoral region may be a possible explanation and thus physical activity is likely to play an important role.To estimate the combined effects of hi

How controlled reactive power compensation can be used to damp power system oscillations is described. This is of particular interest in the case of weakly coupled networks. A comparison is made between two kinds of controllable reactive power elemen

The thyristor controlled series capacitor (TCSC) has been well known as a potential countermeasure against SSR since it was introduced. This paper uses a real case, a local power plant connected to a remote load center through a series compensated ra

Voltage source converters for high-power applications like HVDC and SVC will encourage the use of low commutation frequency which restricts the attainable control performance. In spite of the low switching frequency the control system must be fast-ac

The paper describes a new method to generate the reactance reference for a TCSC, which has been installed in order to provide damping in a power system. The knowledge of the expected oscillation frequency in the power system is used to create a coord
