Project 2 z przedmiotu Przesyl mocy elektrycznej

Imię i nazwisko: Xxxxx Yyyyy

Rok akademicki: 2013/2014

Termin: 9.1.2014

Task 2:

For given simple power network calculate:

• voltages U (magnitude and phase angle of the phasor) in all nodes of electric network,

• active and reactive power (P_i, Q_i) in all nodes of electric network. Note: sign „+“ determines power supply, sign „-“ determines power comsumption,

• active and reactive power flows (P_ij, Q_ij) on the lines (values and directions),

• active power losses in power network.

Use the Newton-Rhapson method or Gauss-Seidl method. You can solve this task manually or using software MATLAB. In case of using MATLAB, please, print the script of the program.
