摘要： Four sets of a first pair of diodes, a second pair of diodes and a GTO breaker are connected between the power rectifier, the power inverter and four electric car power supply lines arranged in parallel with each other and separated by two dead sections. Therefore, it is possible to cut off powering current and regenerative current simultaneously by simply turning off the GTO breaker. Further, even if a regenerative electric car is running on the electric car power supply lines, it is possible to prevent the occurrence of an arc at the other dead sections due to a potential difference between two power supply lines. Further, in case of powering/regenerative bus bar accident, it is possible to effectively cut off both a regenerative current and an extension power supply current flowing from the power supply lines by the four GTO breakers of a relatively small interrupt capability without exerting the influence of power suspension upon other adjacent substations supplying the extension power supply current.

摘要： An electric locomotive has two AC-DC converters (B r1 , B r2 ) which are connected in cascade, and a power factor controller (PFC) is connected to one of the converters. Two automatic pulse phase shifters (APPS,, APPS 2 ) are provided for the two converters and controlled by a signal responding to a difference signal between a current flowing in the converters and a reference signal. One of the input signals of the automatic pulse phase shifter is regulated by a bias signal (VB). The output from each of the automatic pulse phase shifters to each of the converters is switched when the measured speed (v) of the locomotive exceeds a predetermined reference speed signal (v R1 ).

摘要： In the control apparatus of an AC/DC power converter, the occurrence of a single-phase line-open in the AC power line is detected by an open-circuit detector (14) so that a detection signal (E14) is generated. The control angle (a) of a converter (3) on the side of occurrence of the single-phase line-open is kept at a given value (a - 80 or 110 degrees) based on the detection signal (E14). At the same time, the current set value of the automatic current regulator (8) is also kept at a fixed value (E21) based on the detection signal (E14).

摘要： A power converter having an ac side connected through a reactor to an ac power source and a dc side connected to a smoothing capacitor and a load, the converter being capable of converting and inverting electric power in accordance with the pulse width modulation control, characterized by comprising: a voltage detection circuit for detecting a voltage on the side of the ac power source when viewed from the reactor; a first judgement section for detecting that the amplitude of a voltage component on the ac side of the power converter, which is included in the ac power source voltage, is above a predetermined value on the basis of an output signal from the voltage detection circuit to produce a signal indicative of the judgement result; a second judgement section for detecting that the amplitude of the ac power source voltage is below the predetermined value to produce a signal indicative of the judgement result; and a gate circuit for performing logical sum of the outputs from the first and second judgement sections to use an output signal from the gate circuit as a detection signal indicative of a power interruption of the ac power source.

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： In a phase control device (2B) for a power converter (1) having controlled rectifier elements (U, V, W, X, Y and Z), a phase detector (10) detects the phase of the AC voltage of the power converter (1) and produces a phase signal (θ). A processing circuit (11 B) receives a feedback signal (FED) of the power converter (1) and compares the feedback signal (FED) with a reference signal (REF) to produce a phase control signal (Ec) enabling the feedback signal (FED) to become equal to the reference signal (REF): A firing pulse determination circuit (12) compares the phase signal (8) with the phase control signal (Ec) to produce firing pulses (TP) which are applied to the controlled rectifier elements (U, V, W, X, Y and Z). Monitoring circuits (41,42) judge whether or not the phase control device (2B) has failed according to the phase signal (θ), the phase control signal (Ec) and a specific firing pulse (TPU) from the firing pulse determination circuit (12).

摘要： A method for controlling a converter in an HVDC power transmission system and a converter with appropriate control means for carrying out said method. The current regulator influences the control angle of the converter in dependence on the difference (l 0 -l d -Δl) between, on the one hand, the measured current (l d ) and, on the other hand, the current order signal (1 0 ) decreased by a current margin value (Δl), controlling the converter with a control angle which is dependent on the one hand, on a proportional component being linear proportional to said difference and, on the other hand, on an integral component corresponding to the time integral of said difference. The current regulator has a proportional regulator part (PR) and an integrating regulator part (INT1). The output signal of the integrating regulator part is limited in the upward direction to a value corresponding to a maximum value of the control angle of the converter. The output signals from the integrating and the proportional regulator part are added to form the output signal of the current regulator. The limiting value of the integrating regulator part is calculated by a calculating circuit as a function of the current order and the ideal direct voltage of the converter. The calculation is made by determining the control angle at which, at a load current equal to the current order, the extinction angle becomes equal to the smallest permissible turnoff angle. From this angle there is then subtracted the output of the proportional unit at a current equal to the current order, and the result constitutes the limiting value for the integrating regulator part.
