    摘要: In order to place into operation a group of power converters which are connected in series as concerns the direct-current mode and in parallel as concerns the alternating-current mode, of a power or current converter operating in a rectifying mode of a high-voltage direct-current transmission installation, the control pulses of the group of power converters to be placed into operation are set at a range of approximately 100 to 115 electrical degrees. The bypass or shunt switch of such group of power converters subsequently receives an opening command. The control pulses, after accomplishment of opening of the bypass or shunt switch are shifted in accordance with a predetermined linear ramp function in the rectifying range and thereafter the control pulses are delivered by means of a pole current regulator. The placement into operation of a power converter operating in the inverting mode is accomplished in a similar fashion. Reactive power swings or fluctuations between the network and the power converters are avoided.

    摘要: A two-quadrant converter having a connected superconducting magnetic memory used as a chopper circuit or an actuator for stabilizing networks and for short-term bridging of power failures (e.g., uninterrupted power supply). For example, a two-quadrant converter is connected on the input side to an intermediate d.c. circuit of a converter whose intermediate circuit voltage is stabilized by an indirect capacitor. A magnetic memory is charged and discharged, respectively with energy in cyclic intervals, i.e. in conjunction with interposed free-wheeling intervals. Charging takes place via triggered thyristors, discharging via conducting diodes, with blocked thyristors. When the magnetic memory is in a charged state and is to be neither charged nor discharged over lengthy intervals, its current can be conducted in the free wheel via a closed mechanical switch connected in parallel.

    摘要: In order with a low degree of equipment complexity to convert two alternating-currents of 16 2/3 Hz of two separate single-phase generators (G1, G2) of approximately the same power into a three-phase current with 50 Hz, the single-phase generators are connected via a SCOTT transformer (Tr1) to a rectifier (SR1) of a converter with a direct-voltage intermediate circuit (3-6). The direct current transmitted through the direct-voltage intermediate circuit is transformed into three-phase current by two inverters (SR2, SR3) connected in series, and supplied to a national power system (10) via power transformers (Tr2, Tr3). The two single-phase generators (G1, G2) are controlled by one generator voltage controller (42) in each case, which affects the excitation of the single-phase generators (G1, G2) via a field rectifier (43), at the same amplitude of their generator voltages (u1, u2). Moreover, the single-phase generators (G1, G2) are controlled at a phase shift of their generator voltages (u1, u2 ) of 90.degree..sub.el by a load angle controller as a function of the load angles (.delta.1, .delta.2). For this purpose, desired-value signals (P1.sub.s, P2.sub.s) are formed by a turbine balance controller in order to control the fuel supply of turbines (Tu1, Tu2), which drive the single-phase generators (G1, G2).

    摘要: A method and apparatus for controlling the real and reactive power behavior of a high voltage transmission (HDT) system characterized by a rectifier station connected to a first three phase network and an inverter station connected to a second three phase network. The rectifier and inverter stations have positive and negative station-halves connected to each other over positive and negative D.C. transmission lines to form positive and negative poles, each station having a common ground or return wire. Each station is equipped with current and voltage regulators, as well as control angle and quenching angle regulators whereby in case of the tripping of line protective devices monitoring line current in a faulty pole, and the consequent unloading of the faulty pole, the regulation of the intact pole assumes control for a short time to protect against network transients resulting from the load drop. In the event of a line disturbance, both the current set point for the current regulator and the control angle set point for the control angle regulator of the intact station-half of the intact pole are increased according to preset functions, with the control angle set point subordinated to the magnitude of the current angle set point.

    摘要: With electric valves (7) having several series-connected thyristore (T1 . . . Tn; T1' . . . Tn'), individual thyristors may become defective, so that they do not withstand the blocking voltage applied to them. For the simplified checking of such defects, a process is specified which does not require any individual monitoring on the spot, i.e. for high potential. For this purpose, in the blocked state of the valve (7), all thyristors of one current direction, apart from at least one thyristor being tested, are triggered within a predeterminable triggering interval. If a valve current (i.sub.R) then flows, an indicating and registering device (A1 . . . An) indicates in which thyristor stage the defect has occurred. This status check is preceded by a preliminary test in which it is checked whether all thyristor triggering channels are in order. All thyristors are triggered in this test. If no valve current (i.sub.R) occurs, a triggering channel fault signal (S.sub.U0) is generated.
