制御回路が構成されている。 As a DC power transmission system converter, it is operated at point A, which is the intersection of the operating curves of converter 1A and converter 1B in Fig. 2, but in general, DC power transmission system is accommodating between AC systems 6A and 6B. In order to control the transmitted power, a constant power control circuit 44 is provided as a converter of the DC power transmission system, and a power detector 4 detects the power reference value determined by the power setting device 41 and the transmitted power.
By inputting the power detection value which is the output of 3 into the adder 42 and using the signal obtained by amplifying the difference by the constant power control circuit 44 as the current reference value, the power is transmitted to the power reference value. The control circuit is configured so that the power follows.
即ち、第２図の特性曲線から明らかなように、

流を制御して送電電力を制御するようになる。 That is, as is clear from the characteristic curve in Figure 2,
The converter operating as a reverse converter determines the DC voltage, and the converter operating as a forward converter controls the DC current to control the transmitted power.

される。 On the other hand, in order to control reactive power, the converter must be operated in either forward converter operation or inverse converter operation.
It is considered a type of lagging load, and it is a well-known fact that its power factor is almost proportional to the control delay angle or advance angle of the converter. Therefore, in order to control reactive power, the reactive power setting is used as a control circuit of the converter. The reactive power reference value determined by the device 45 and the reactive power detection value which is the output of the reactive power detector 47 that detects reactive power are input to the adder 46, and the difference between them is input to the constant reactive power control circuit 4.
The reactive power is controlled by adding the error amplified signal in step 8 and the minimum margin angle reference value in adders 17A and 17B to control the margin angle reference value.

Of course, when controlling the reactive power of the AC system 6A, it is necessary to detect the reactive power of the AC system 6B, and when controlling the reactive power of the AC system 6B, the reactive power of the AC system 6B is of course detected. Even if the reactive power of the AC system 6A is controlled when the converter is operated, the converter 6 is controlled by the output of the reactive power control circuit 48.
Even if the margin angle of B is controlled, converter 1
Since the control angle of A changes, the reactive power of the AC system 6A is naturally controlled.

う不具合が生じることになる。 Now, hypothetically, when operating at point A in Figure 2, the constant reactive power control circuit 44 works to increase the delayed reactive power consumed by the converter 1B, and as the margin angle reference value increases, the DC voltage decreases. Suppose that the operating characteristic curve shifts from 2, 0, 5 to 2', 0', 5'. On the other hand, the constant power control circuit 44 works to increase the DC current to compensate for the drop in DC voltage in order to make the transmitted power follow the power reference value, and the operating characteristic curve of the converter 1A is B,
There is a transition from C to A', B', and C', and the operating point of the converter shifts from point A to point A'. (If we consider the transmitted power as the product of DC voltage and DC current, the curve where P = constant becomes a hyperbolic curve, as shown in Figure 2, and there is always an operating point on this curve.) Since converters have a current rating, they cannot pass a DC current higher than the rated current.
Therefore, although not shown in the block diagram of FIG. 1, the output of the constant power control circuit 44 is equipped with a limit circuit to prevent more than 100% of the DC current from flowing, so that the DC current does not exceed the rated value. There is. Therefore, if the margin angle is increased to control reactive power, the DC current will increase to control the transmitted power, but if the DC current attempts to flow more than 100%, a limit will be applied. As shown in Figure 2, the constant current characteristic parts of B' and C' are DC current.
If it corresponds to 100%, the DC current is 100%
Since the limit is applied and only the margin angle increases, the operating curve of the inverse converter becomes N', H', H', and the operating point of the converter shifts to point A'.
Since point A'' is not on the constant power curve, a problem naturally occurs in which the transmitted power of the DC transmission system decreases.
本発明は以上述べた不具合を解消し、送電電力

The present invention aims to eliminate the above-mentioned problems and provide a method for controlling a converter that can control transmitted power to a constant level.

The present invention focuses on the fact that when the margin angle increases and the DC current reaches 100% in order to control reactive power, a difference occurs between the power reference value and the detected value. This is to prevent the transmitted power from decreasing by applying restrictions.

FIG. 2 shows a schematic block diagram of a control device for a converter according to an embodiment of the present invention. Components with the same functions as those in FIG. 1 are denoted by the same reference numerals, and explanations thereof will be omitted.

さくなるように構成されている。 The configuration includes an amplification circuit 51 for power reference value and power detection value.
An adder circuit 52 for the output of the reactive power setter 45 is provided, and the output thereof is added to the adder circuit 46 at the next stage.
A reactive power reference value is input to the reactive power setting device, and when the detected power value becomes smaller than the power reference value, the reactive power reference value, which is the input signal of the adder 46, is input to the reactive power setting device. It is configured so that it is smaller than the value determined by .
直流電流が100％以下の場合においては定無効
電力制御回路４８の働きで余裕角が変化して無効

ので、その差は現われず、従つて増巾回路５１の
出力は０のままであり、第１図の制御ブロツク図
の場合の作用と全く同一であることは明らかであ
る。 When the DC current is 100% or less, the constant reactive power control circuit 48 works to change the margin angle and control the reactive power so that the constant power control circuit 44 makes the power reference value and the detected power value equal. Since the control is being performed, the difference does not appear, so the output of the amplifier circuit 51 remains 0, and it is clear that the operation is exactly the same as in the case of the control block diagram of FIG.

せる必要がある。 On the other hand, if the margin angle increases and the transmitted power decreases, a difference will occur in the output of the adder 42. This works so that the reactive power reference value actually input to the adder 46 is reduced by the action of the adder 52 than the reactive power reference value determined by the output signal of the reactive power setter. Therefore, when the transmitted power tries to decrease from the power reference value, the reactive power reference value input to the adder 46 is controlled, and the margin angle further increases even if the DC current reaches 100% for reactive power control. It does not become controlled as it does. In addition, the amplification circuit 51 not only amplifies the power reference value and the power detection value, but also includes an appropriate phase lead/lag circuit or the like to prevent phenomena such as hunting from occurring in the converter during such operations. It is also necessary to provide an anti-hunt circuit if necessary.

一の構成作用で行うことができる。 In the present invention, the margin angle has been explained as being controlled by the output of the reactive power control circuit, but the converter control circuit includes a constant voltage control circuit that controls the DC voltage by following the voltage reference value. In this case, the voltage reference value is controlled by the output of the reactive power control circuit, but even in such a case, it is also possible to carry out the configuration according to the present invention. Furthermore, although the present invention has been described as controlling the reactive power of the AC system, when controlling the AC voltage of the AC system, the change in AC voltage is the same as the change in reactive power and the reactance of the AC system. Since it can be roughly expressed as a product, it can be performed with exactly the same configuration and operation simply by replacing the reactive power of the present invention with an alternating current voltage.

As explained above, when the power reference value becomes larger than the power detection value, the DC power transmission system can secure the transmitted power and perform stable power interchange by placing restrictions on the reactive power control circuit. It is possible to realize a method of controlling a converting device.
