    • 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.
    • 为了控制网状电网(30)中的功率流,至少一个可变电阻模块(11)被插入到电力网(30)的传输线(3)中。 在外部驱动器(13)中,产生外部控制器(14)并将其施加到可变电阻模块(11),以使其电阻发生变化。 例如,使用高温超导体模块或液态金属限流器模块作为可变电阻模块(11)。 因此,使用加热器或磁场电感器作为用于引起可变电阻模块(11)的电阻变化的驱动器(13)。 使用可变电阻模块(11)使得可以以比常规机电开关补偿更少的组件损耗来控制电力网络(30)中的功率流,并且以比柔性AC传输系统设备更低的成本来控制功率流。
