Abstract

This invention is to improve the stability in voltage control for the voltage fluctuations of an AC power source. This converter controlling device is provided with a voltage controller 10, which outputs the output current command of a thyristor converter 3 by operating the feedback control of the DC circuit voltage of the thyristor converter 3, which converts the voltage of an AC power source 5 into a DC voltage for supplying a load with DC power, a current controller 13 which outputs the output voltage command of the thyristor converter 3 by operating the feedback control of the output DC current of the thyristor converter 3, a phase controller 14 which controls the thyristor ignition phase angle of the thyristor converter 3, in such a way that the output voltage average value of the thyristor converter 3 becomes proportional to its output voltage command, an AC voltage detector 15 which detects the voltage of the AC power source 5, and an amplitude computing element 20 which calculates signals proportional to the amplitude of this AC voltage. The output voltage command of the thyristor converter 3 is corrected by dividing the output voltage of the thyristor converter 3 by the voltage amplitude of the AC power source 5, the output of the amplitude computing element 20.

Secondly, the comparator 9 compares the output current command of the fluid controller 3 with the output of the voltage controller 10 and the output current of the brake fluid converter 3 detected by the current detector 11 and uses the current The controller 13 performs feedback control to output the output voltage command of the sluice fluid converter 3. Furthermore, the phase controller 14 is used to control the gate so that the average output voltage of the gate fluid converter 3 proportional to the output voltage command of the gate fluid converter 3 output from the current controller 13 can be obtained. The arcing phase angle of the sluice fluid of the fluid transformer 3. In this case, if the voltage amplitude of the AC power source 5 is set to V a < = ', the relationship between the arc starting phase angle α of the sluice fluid and the average output voltage 値 V t of the sluice fluid converter 3 is as follows: (1) is generally shown. Therefore, the phase controller 14 will determine the arcing phase angle α in such a manner that the following formula (2) can be established according to the output voltage command of the gate fluid converter 3.

Invention Explanation (29) In the output voltage command of the converter, the result of multiplying the output of the adder 2 4 is input to the phase controller 1 4 as a modified output voltage command of the sluice fluid converter. . Next, the operation of the control device of the thyristor of the present embodiment configured as described above will be described. In FIG. 4, since the high-pass filter 23 only outputs the changed part of the input, when the AC power supply 5 does not generate a voltage change, the output is 0. At this moment, the output of the adder 2 4 is 1 and the multiplier 2 The output of 5 is the same as the output of the current controller 1 3, and the multiplier 2 5 has no effect here. On the other hand, when the amplitude of the voltage of the AC power supply 5 fluctuates rapidly, the output of the amplitude calculator 20 is counted down by the inverse calculator 22, and the changed part is output from the high-pass filter 23. As a result, the output of the adder 24 will not become 1, and the output voltage command of the gate fluid converter of the input of the phase controller 14 will be corrected. For example, when the amplitude of the voltage of the AC power supply 5 fluctuates rapidly, the output of the inverse calculator 22 is reduced, and the output of the high-pass filter 23 is changed to a negative value. Therefore, the output of the adder 24 will become 1 or less, and the output voltage command of the gate fluid converter of the input of the phase controller 14 will be corrected in the direction of smaller 较. Then, by reducing the output voltage command of the gate fluid converter of the input of the phase controller 14, the output voltage of the gate fluid converter 3 caused by the voltage rise of the AC power supply 5 can also be increased.

Description of the invention (43) The pulse width is controlled to control the PWM conversion器 3 a. The 3 a. Next, the function of the control device of the PWM converter of the present embodiment configured as described above will be described. The AC voltage of the PWM converter 3a is approximately proportional to the input of the PWM control circuit 19 and VTC *. In addition, the difference voltage between the AC voltage of the PWM converter 3a and the voltage of the AC power supply 5 is applied to the power supply filter 6a to determine the size of the AC power. Therefore, the voltage fluctuation of the AC power supply 5 will be the main cause of the disturbance. If the voltage of the AC power supply 5 fluctuates, in the conventional configuration (Fig. 20), the parent current will be disturbed. For this reason, the constitution of this embodiment is to remove the influence caused by the disturbance. That is, in FIG. 13, even if the voltage of the AC power supply 5 changes, it can be targeted and borrowed with the AC voltage commands Vsc * 'Vtc * of each phase superimposed by the adders 28R, 28S, and 28T. The signals e R, es * e τ proportional to the phase voltages of the AC power source 5 detected by the AC voltage detector 15 perform pulse width modulation, so the AC voltage of the PW M converter 3 a will only change the AC power source 5 Voltage fluctuations. As a result, since the difference voltage between the AC voltage of the PWM converter 3a and the voltage of the AC power source 5 does not change, the AC current 5 is not scattered due to the fluctuation of the AC power source 5.

As a result, even when the voltage of the AC power source 5 fluctuates, 'the DC voltage of the smoothing capacitor 4 can be stably controlled', and stable electric power can be constantly supplied to the load inverter 1 and the motor 2 (the first and second embodiments) Modified Example) Although the effective and reactive current controller 18 of the embodiment shown in FIG. 13 described above can be used as the effective and reactive current controller 18 ′ shown in FIG. 21, it is not limited to this.
