Quasistationary Library

Description

The Quasistationary library addresses the analysis of electrical circuits with purely sinusoidal voltages and currents. The following are the main characteristics.

•	Only pure sinusoidal voltages and currents are taken into account, higher harmonics are not considered.

•	Electrical transients are neglected.

•	The electrical components are strictly linear.

•	The angular frequency $ω$ of the voltages and currents of a circuit is determined from a reference angle $γ$ by means of $ω = \overset{&period;}{γ}$ .

•	The reference angle $γ$ is not a global quantity, it propagates through the connector; this allows independent circuits with different frequencies to be simulated in one model.

•	The connectors contain the real and the imaginary part of the voltage and the current RMS phasors.

Phasors

•	The purely sinusoidal voltage $v = V_{pk} \cos (ω t + φ) = \sqrt{2} V_{rms} \cos (ω t + φ)$ in the time-domain is represented by a complex rms phasor $ν = V_{rms} \exp (j φ)$ , where $j$ is the imaginary unit.
