摘要： A control device for a converter used in a DC transmission system comprises an automatic current regulator (56A, 56B), an automatic margin-angle regulator (42A, 42B) and an automatic voltage regulator (30A, 30B). The output of the automatic voltage regulator (30A, 308) is supplied to the automatic margin-angle regulator (42A, 42B) to vary a margin-angle reference of the automatic margin-angle regulator (42A, 42B).

摘要： A converter control system for DC power transmission line performs the following operation. When the DC current flowing through an inverter (1B) decreases to a value being smaller than a rated current value by a value in excess of a predetermined value (E35), a reference voltage value (E14B) determining the DC voltage of the inverter (1 B) decreases. The decrease of this reference voltage value (E14B) is limited to a given extent, so that a partial constant current characteristic portion (j, k in Figure 6) appears at the voltage decreased portion in the DC voltage/current characteristic of the inverter (1B). Then, an automatic voltage regulator of the inverter (1 B) is rendered always active.

摘要： A power converter control apparatus includes an automatic power controller (APC) for controlling a rectifier (1A) and an automatic reactive power controller (AQC) for controlling an inverter (1B). The inverter (1B) is coupled via DC power transmission lines (3) to the rectifier (1A). An output (E44) from the automatic power controller (APC) is utilized to change a control angle (or margin angle) of the inverter (1B) if a DC current (ld) flowing through the DC power transmission lines (3) increases to exceed a rated current value of the apparatus, thereby allowing a stable power transmission.

摘要： A synchronous condenser is provided on an AC bus line which is connected to an AC power system via a circuit breaker. The AC bus line and a DC bus line are connected via a power converter system. In such a system, if three conditions: the breaker is opened; the synchronous condenser is under operation; and the power converter operates as an inverter, are met, the power converter is driven into a zero power factor operation, i.e., an operation to cancel a capacitive reactive power on the AC bus line including AC filters in order to prevent the synchronous condenser self-excitation.

摘要： A series-compensated converter station included in an installation for transmission of high-voltage direct current comprises a converter (SR1, SR2) with at least one 6-pulse bridge (BR). Via series capacitors (SCR, SCS, SCT) the 6-pulse bridge is connected to a three-phase alternating-voltage network (N1, N2) with a fundamental frequency (f01, f02). Control equipment (CE1, CE2) generates an ordered value (AOL) of a control angle ( alpha ) for valves (V1-V6) included in the 6-pulse bridge in dependence on a limiting signal (AMAXL) capable of being influenced. An amplitude signal (AMPL) is formed which corresponds to the amplitude (C1) for a component (C1cos(2 pi f0t + rho 1)) of the fundamental frequency in the direct voltage (Udb) of the 6-pulse bridge and a compensating signal (ACOMP) is continuously calculated in dependence on a sensed voltage (Un1, Un2) at the converter station and on the amplitude signal. The limiting signal is formed in dependence on the compensating signal for the purpose of maintaining the commutating margin ( gamma m) for the valves equal to at least the preselected value ( gamma p) in case of unbalance between the voltages (UCR, UCS, UCT) of the series capacitors.

摘要： A converter assembly for power transmission by means of high-voltage direct current has a first current-source, line-commutated converter (SRA) and a second voltage-source, self-commutated converter (SRB). The converters are d.c. series-connected to each other and are connected to an alternating-voltage network (ACN). The second converter (SRB) has control members for controlling the direct voltage (Udb) of the converter by influencing the phase position ( delta ) of the internal alternating voltage (Uvb) of the converter and hence the flow of active power between the converter and the alternating-voltage network. The control members comprise a regulator (S3, Ud-reg) for controlling the direct voltage (Udb) of the converter in dependence on the difference between on the one hand a reference value (Udbref) of the direct voltage of the converter, supplied to the control member, and on the other hand a sensed value (Udbm) of this direct voltage.
