Phase Coordinates Method: An Example of Compiling a Network Model

Consider an example of compiling a power transmission model using the phase coordinate method. In fig. 1 shows the power transmission, a mathematical model of which must be compiled. It is necessary to determine the currents in the short circuit mode at the beginning of the line.

Phase Coordinates Method: Short Circuit with Break Model

Some complex types of damage can occur in power lines, for example, a short circuit with a wire break. This mode can occur when a wire of any phase falls to the ground (Fig. 1).

Phase Coordinates Method: Short Curcuit Model

In the phase coordinate method for modeling damage in the power line, the corresponding damage model is used with its transmission matrix. The damage model is composed of a set of active resistances.
