摘要： In a reactive power compensator used for capacitive or inductive reactive powers in alternating-voltage networks, a capacitor is connected to an alternating-voltage network for a short time by means of a thyristor switch. In order to reduce the voltage load on the thyristor switch, a discharge circuit is connected in parallel with the capacitor. Via this circuit, the capacitor can discharge, after being disconnected from the alternating-voltage network, with such a speed that the voltage occurring at the thyristor switch is no greater than about 1.5 times the maximum network voltage. In the discharge circuit, a variable inductive reactive resistance can be a discharge circuit choke having an iron core or the primary winding of a transformer. When the capacitor is connected to the alternating-voltage network, the discharge circuit choke is unsaturated and its reactive resistnace is large (or the transformer secondary is open) so that no significant leakage current can flow via the discharge circuit. After the capacitor is disconnected from the alternating-voltage network, the discharge circuit choke is saturated and its reactive resistance is small (or the transformer secondary is shortcircuited) so that a large discharge current can flow. No switching element is required in the discharge circuit. In order to limit the rectifier current of the thyristor switch and to change this rectifier current with time, an air choke is provided. The maximum rectifier voltage is limited by surge dissipators of zinc oxide.

摘要： To reduce unwanted current oscillations such as, for example, of the second harmonic of the system frequency (f.sub.o), the firing angles (.alpha.1, .alpha.2) of a link-circuit rectifier (1) and of a link-circuit inverter (2) are compensatingly acted on in push-pull mode. For this purpose, a direct-current link-circuit current signal (S5, S5'), which contains the instability or the current oscillation to be compensated, is fed by means of a current detector (5, 5') to a bandpass filter (16, 16', 16") which is tuned to the frequency (f.sub.o, f.sub.x) of the respective current oscillation. The phase of a bandpass filter output signal (S16) is shifted by 90.degree. trailing in a 90.degree. phase-shifting section (15, 15', 15"). A compensating signal (S15,S15', S15") obtained in this manner is fed to first and second function generators (13, 13', 13"; 14, 14', 14"). The first function generators allow the positive component (S13) to pass and the second function generators allow the negative component (S14) of the compensating signal to pass. The output signal of the first function generator passes via a switch (12') to a summing section (11') for forming the cosine of the firing angle (.alpha.2) of the link-circuit inverter (2). The output signal of the second function generator passes via a switch (12) to a summing section (11) for forming the cosine of the firing angle (.alpha.1) of the link-circuit rectifier (1). By these means, the firing angle (.alpha.2) of the link-circuit inverter (2) is reduced when the direct-current link-circuit current signal is dropping and the firing angle (.alpha.1) of the link-circuit rectifier (1) is increased when it is rising.

摘要： Where different 3-phase systems are connected to each other via two static converters having an intermediate direct-current circuit, the exchange of power via the intermediate direct-current circuit can be interrupted by a severe disturbance, for example by failure of a static-converter or by line or busbar faults causing a short-circuiting of one of the static converters. This interruption means a change in the balance of effective power and, associated with this, a shedding of reactive load for the other undisturbed 3-phase system. To reduce high dynamic overvoltages which can lead to plant components being endangered or to operational disturbances, the firing angle of the static converter remaining in operation is regulated with dependence on the alternating voltage of the alternating-current system connected to this static converter, in such a manner that the overvoltage is reduced. This is carried out by regulating the current. The firing angle can be adjusted simultaneously with the short circuiting of the intermediate direct-current circuit by means of a short circuit device.
