Julia electrical engineering package
View the Project on GitHub christiankral/ElectricalEngineering.jl
This is a Julia package on electrical engineering based on Unitful and PyPlot. The package ElectricalEngineering.jl is tested with Julia 1.1.0. To install the package, start Julia and hit ]
to switch to the package manager.
add PyPlot Unitful ElectricalEngineering
In order to update to the actual version of GitHub in the package manager, hit ]
and apply:
update ElectricalEngineering
To switch back to the Julia REPL and to start working hit Backspace
.
The module ElectricalEngineering.jl has to be loaded by using ElectricalEngineering
. In order to use all the features of ElectricalEngineering.jl, modules Unitful and PyPlot have to be loaded as well. It is thus recommended to appy:
using Unitful, Unitful.DefaultSymbols, PyPlot, ElectricalEngineering
pol
to generate a complex quantity based on the length and the angle (polar representation)
julia> U1 = pol(2V, pi)
-2 + 0im V
julia> U2 = pol(sqrt(2) * 1V, 45°)
1 + 1im V
j
representing the imaginary unit equivalent to 1im
phasor
phasorsine
angulardimension
phasordimension
∥
julia> 4Ω∥6Ω
2.4000000000000004 Ω
julia> 4Ω∥(j*4Ω)
2.0 + 2.0im Ω
printuln
julia> U1 = 300V + j*400V
julia> printuln("U1", U1, kV)
U1 = 0.3 kV + j 0.4 kV
= 0.5 kV ∠ 53.1301°
julia> printuln("real(U1)", real(U1),kV)
real(U1) = 0.3 kV
julia> printuln("U1", U1, V, label="(a)")
(a) U1 = 300 V + j 400 V
= 500 V ∠ 53.1301°
