<p>For controlling power flow in meshed power network (30), at least one variable resistance module (11) is inserted into a transmission line (3) of the power network (30). In an external driver (13) an external control effort (14) is produced and applied to the variable resistance module (11) for causing a change of its resistance. For example, a High Temperature Superconductor module or a Liquid Metal Current Limiter module is used as the variable resistance module (11). Accordingly, a heater or a magnetic field inductor is used as a driver (13) for causing a change of resistance of the variable resistance module (11). Using a variable resistance module (11) makes it possible to control power flow in a power network (30) with less wear of components than in conventional electro-mechanical switching compensation and with lower costs than with flexible AC transmission systems devices.</p> |
