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： The invention relates to a hybrid for an AC mains system, with the hybrid filter having a passive and an active filter which are electrically connected in series, and with the active filter having a voltage source. According to the invention, a tuned filter, which is tuned to the rated frequency of the AC mains system, is electrically connected in parallel with the active filter. This results in a hybrid filter for an AC mains system, whose active filter is not loaded by the fundamental current component.

摘要： A thyristor-controlled capacitor bank includes a thyristor switch and a capacitor bank. The capacitor bank is split into at least two series-connected capacitor groups. A series circuit including a thyristor switch and an inductor coil is connected in parallel with the capacitor group which is remote from a capacitor group at a mains power supply connection. A thyristor-switched capacitor bank is thus obtained which has a thyristor switch that therefore only needs to be constructed for a fraction of the mains power supply voltage itself, which is a major advantage for economic reasons.

摘要： A method and an apparatus can determine the orders (z) of non-characteristic harmonic currents (Ih) of a second power supply grid, which is coupled to a first power supply grid using an HVDCT system. The apparatus and method also compensates for these non-characteristic harmonic currents (Ih), which are produced as a result of distortion (Uh) of the supply voltage (U1) which exists in the first grid because of a low-frequency harmonic and passes through the short coupling. The order (n) of the existing non-characteristic harmonics is determined by a voltage and/or current measurement of the voltage (U1) of the grid, from which order (n) the order (z) of the generated non-characteristic harmonics in the second grid is determined by a provided voltage-symmetry signal (SMG). This order (z) is supplied to filter logic of a compensation system. The energy quality is thus considerably improved, particularly in the case of grids which are not rigid.

摘要： If in a high-voltage d-c transmission system (HVDCTS), a resonance frequency of an a-c voltage network (NB) connected to the inverter (1B) is located in the vicinity of a voltage component contained in the a-c voltage network, a resonance frequency which often cannot be compensated by a current regulator controlling the rectifier stage (1A) is coupled into the d-c circuit of the HVDCTS via the inverter. Therefore, resonance phenomena which requires an emergency shutdown of the HVDCTS are generated. Therefore, a pilot quantity (U'.sub.d) is formed with a defined phase shift relative to the resonance oscillation of the HVDCTS voltage and added to the output of the current regulator. Thereby, a constant HVDCTS current can be generated for a given operating point and the resonance in the a-c voltage network (NB) can be damped. If the resonance oscillation is determined by two quantities (U'.sub.d, i'.sub.d) of, respectively, the HVDCTS voltage as well as of the HVDCTS current, stable damping of the resonance phenomena can be achieved by the pilot control described with the two quantities even for deviating operating points.

摘要翻译： 如果在高压直流输电系统（HVDCTS）中，连接到逆变器（1B）的交流电压网络（NB）的谐振频率位于交流电压网络中包含的电压分量附近，则共振频率 其通常不能通过控制整流器级（1A）的电流调节器经由逆变器耦合到HVDCTS的直流电路来补偿。 因此，产生需要紧急关闭HVDCTS的共振现象。 因此，导频量（U'd）相对于HVDCTS电压的谐振振荡形成具有规定的相移并被加到电流调节器的输出端。 因此，对于给定的工作点可以产生恒定的HVDCTS电流，并且a-c电压网络（NB）中的谐振可被衰减。 如果共振振荡分别由HVDCTS电压和HVDCTS电流的两个量（U'd，i）确定，那么谐振现象的稳定阻尼可以通过两个描述的导频控制来实现 数量甚至偏离工作点。
