摘要： In the rectifier station (GR), the reference d-c current (J.sub.w) is automatically formed from the differences of a reference current-dependent control angle function and the current controller-dependent control angle (A) on the rectifier side, where the actual d-c current (J.sub.d) is termined by the power-dependent bucking voltage in the inverter state (WR), and that in the latter the difference of the actual d-c current (J.sub.d) and a reference d-c current obtained from the reference power (P.sub.W) through division by the actual d-c voltage (U.sub.d) influences a controller which sets the reference d-c current for the voltage controller (UR) in the inverter station (WR).

摘要： A circuit for controlling the voltage of a network which supplies electrical power to a load having a rapidly varying impedance. The circuit contains a pair of controlled electric valves which are connected in parallel between two conductors of the network and poled for condition in opposite directions. A voltage transformer produces a signal corresponding to the network voltage, which signal is conducted to an integrator and subsequently compared to a preset mean value. The preset mean value corresponds to a desired amplitude at which the positive and negative half-wave cycles of the network voltage are desired to be maintained. In one embodiment, the controlled electric valves are caused to conduct current during respective half-waves of network voltage so as to maintain the amplitudes of the half-waves at the present mean value. Other features are described for compensating for long term drift of the network voltage and for controlling the controlled electric valves by means of logic circuitry.
