Reactive Power Control of Compound Reactive Power Compensation Device

2018 IEEE International Conference on Mechatronics and Automation (ICMA), 2018
A low-cost composite reactive power compensation model is proposed. The model consists of a Thyristor Switched Capacitor (TSC), a Thyristor Controlled Reactor (TCR) and a Static Var Generator (SVG). Firstly the paper completes the preliminary compensation by the large-capacity TSC+TCR module, and then the small-capacity SVG is responsible for ...

Towards reactive power markets. Part 1: reactive power allocation

IEE Proceedings - Generation, Transmission and Distribution, 2006
Although real power is the main traded commodity in electricity markets, reactive power plays a crucial role in power systems reliability and security. In competitive electricity markets, no market participant wants to subsidise others in any way. Market participants utilise the network in different ways to maximise their profits.

ITER Reactive Power Compensation Systems: analysis on reactive power sharing strategies

2019 IEEE International Conference on Environment and Electrical Engineering and 2019 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe), 2019
The goal of nuclear fusion is one of the most important challenges in contemporary research and technological development. Its achievability will completely change the energy scenario and reduce the dependence on fossil fuels in the production of electricity. ITER project is focusing the efforts of many countries and researchers in the demonstration of

Optimal Phase-Shift Control to Minimize Reactive Power for a Dual Active Bridge DC–DC Converter

IEEE transactions on power electronics, 2019
In a dual active bridge (DAB) dc–dc converter, modulating the phase-shift ratios can suppress reactive power and increase the efficiency under non-unity voltage gain conditions. Derivation of the optimal phase-shift ratios to achieve the minimum reactive

Reactive power and power factor

Electrical Engineering, 1933
GENERAL definitions exist for potential, current, and active and reactive power, that are independent of wave form and of circuit conditions. In order to use these quantities in circuit analysis when there are harmonics present, it is necessary to know their individual harmonic components.

Power, reactive volt-amperes, power factor

Electrical Engineering, 1933
The relation between power, reactive volt-amperes, and power factor is discussed for sinusoidal electromotive forces and currents. Reactive volt-amperes is defined as the flow of stored energy into the circuit and is deduced from the stored energy cycle.

Reactive and Fictitious Power

Transactions of the American Institute of Electrical Engineers, 1933
In this paper the single-phase and polyphase definitions of reactive power are considered. The single-phase definition is unsatisfactory when the current and voltage wave forms are complex. The polyphase definition is the better but requires the independent recognition of the effects of distortion and, in the case of four or more wires, mesh ...
