Power Grid#

The Power Grid block implements a mathematical model of a symmetrical source of electromotive force, the voltage of which is described by the formula (1) :

(1)#\[U=\sqrt {2} \cdot U_д \cdot sin(2\cdot п \cdot f \cdot t+ \phi) \]

The user sets parameters in the block properties:

U\(_e\) - effective voltage, [V];

\(f\) - frequency, [Hz];

\(\phi\) - phases, [deg].

In order to calculate short-circuit currents, the block properties provide the possibility to set the required parameters.
