Dynamic reactive compensation: Reactive power fundamentals

2011 IEEE/PES Power Systems Conference and Exposition, 2011
The panel presentation is a tutorial on the concept of reactive power and discusses its implications in power systems. The impact of reactive power on the system voltage as well as on component ratings and component size is discussed. The concept of reactive power and the so called ‘instantaneous’ reactive power are presented.

Combined compensation strategies based on instantaneous reactive power theory for reactive power compensation and load balancing

2011 International Conference on Electrical and Control Engineering, 2011
The compensation system introducing Δ-connected and Y-connected compensation networks can be used to eliminate negative sequence components and zero sequence components of unbalanced load currents and improve power factor to unity. To summarize the existing achievements, this paper applied instantaneous reactive power theory to the control strategies ...

Adaptive Nonlinear Compensation of Reactive Power

1983 American Control Conference, 1983
The potential of a new adaptive control for reactive power sources is investigated. In the large disturbance regimes, the adaptive signals supplement the nominal, thyristor activated, reactors and capacitors in manipulating the network voltage. Convergence of the scheme, and its relationship to the inherent system nonlinearities is considered.

Reactive power compensation on distribution feeders

Proceedings The Twenty-Ninth Southeastern Symposium on System Theory, 2002
The optimal sizing and placement of shunt capacitors on distribution feeders has received considerable attention from researchers for many years. This paper provides an analysis of several of the general solution methods found in such literature. The validity of certain simplifying assumptions are addressed and additional insights are provided.

Robust compensator of harmonics and reactive power

Proceedings of PESC '95 - Power Electronics Specialist Conference, 2002
This paper presents a robust compensator of harmonics and reactive power for electric power systems, which consists essentially of an electronic source and a robust controller. This compensator permits us to eliminate harmonics to an acceptable level and to compensate reactive power.

Reactive power compensation of nonlinear load

13th International Conference on Development in Power System Protection 2016 (DPSP), 2016
The paper concerns reactive power compensation of nonlinear load. At the beginning power definitions and problems related to calculation of reactive power are presented. Based on the definitions, simplified distortion factor is determined. Two possibilities of reactive power compensation are analyzed.

The use of the SSC as reactive power compensator

, 2007
The paper deals with the possibility of employing the Custom Power Static Series Compensator (SSC), whose primary aim is to compensate voltage sags, also as a Reactive Power Compensator. The idea arises from the observation that such device does not work
