    摘要: The invention relates to a method for regulating a voltage (U) in a distribution network (VN) that supplies nodes (KN) with voltage via mains power lines (NL). In said method, a node (KN), which recognizes that the local voltage of the distribution network (VN) present at said node lies above or below a permissible supply voltage range, switches from slave mode (SB) to master mode (MB) and in said master mode (MB) regulates the local voltage (U) that is present, by drawing or supplying reactive power (Q) in order to reach the permissible supply voltage range. The node (KN) then indicates this to other nodes (KN) of the distribution network (VN) that are in slave mode (SB) by modulating an indication signal pattern (ASM) onto the reactive power (Q) being drawn or supplied by said node, the signal pattern having a signal parameter which is proportional to the amplitude of the reactive power (Q) that is drawn or supplied by said node (KN).

    摘要: A method for regulating a wind energy installation including a rotor-driven generator, a converter connected to the generator, and a controller that regulates power emitted into an energy transmission system to within a limit value involves determining a maximum current value in a connection path, determining a current reserve value for power emitted into an energy transmission system, and determining a correction value for following a limit value of the emitted power from the maximum current value and the current reserve value. The wind energy installation and the method for its regulation also includes the use of a limitation device configured to set a phase angle between an emitted current and voltage of an electrical system in response to a selection signal in such a way that primarily active power or primarily reactive power is fed into the energy transmission system when the maximum current value is reached.

    摘要: It is presented an apparatus comprising: a converter (118) having an AC side and a DC side, a switch (112) adapted to be connected to a transmission line (104) on a first side and the switch being adapted to be connected to a load (122) on a second side, the second side also being connected to the AC side of the converter, an energy storage device (120), connected to the DC side of the converter. In a first operating mode, the switch is closed, such that an energy storage current flows to or from the energy storage device to charge or discharge the energy storage device, respectively, using the converter' for any necessary conversion between AC and DC. In a second operating mode, the switch is open, preventing current from flowing from the transmission line to the converter, and the energy storage device supplies a direct current which is converted to an alternating current by the converter. Moreover, in the first operating mode, the apparatus is configured such that a power transfer on the transmission line corresponds to a surge impedance loading of the transmission line, by affecting the energy storage current. A corresponding method is also presented.
