(If it is a single wire, problems such as touching underground metal will occur if it is a ground-to-ground route, and even if a conductor is used as a return route, the loss due to the conductor will increase.) On the other hand, if a pair of positive and negative high-voltage transmission lines were used and one pair collapsed, it would stop, and the return load could be reduced qualitatively by circulating the negative transmission line through Ichihara. In the case of a return path to the earth, the earth flow can be reduced, and in the case of a yti12! conductor, the return path can be reduced in loss of body flow.

When IMt and IJa (M) are equal to each other, these TMR transmission lines circulate in the flow system and the circuit is intercepted, so the return conductor 3 is unbalanced. The loss ij is limited only to that due to the resistance of the DC high-voltage transmission lines 1 and 2.

In the various conventional circuits shown in Fig. 1, if the DC high voltage transmission line 2 is struck by lightning and an arc occurs, the first thing to do is to stop the operation of converters 6 and 7. Generally speaking, there is a method in which the engine is restarted after a predetermined period of time has passed since the engine stopped, and the engine is returned to the operating state before the accident. Therefore, while the C converter 6.7 is stopped, the 1 flowing through the DC high-voltage transmission line 1 naturally increases the circulation flow through the return conductor 34, so the converter 4.5 t

自流送電方式とは言い難い欠漬があった。1. If the fault in the iFN high flow pressure transmission line 2 is permanent, such as a disconnection, converters 6 and 7 cannot be started, and the 1O flow pressure transmission line 1 will fail. city/jlftj

If there is sufficient flow capacity, converter 6 should be connected in parallel with converter 4, and converter 7 should be connected in parallel with converter 5. It is also possible to continue sending 1 without any interruption. However, in this case, ii.
Since the power flows into the return conductor 3, not only is it necessary to constantly equip a transmission line with a large amount of power, but the loss due to the transmission line is approximately four times that of bipolar operation, making it a more efficient self-current transmission. There were some flaws that could hardly be called methods.

とを目的とする。Therefore, the present invention has been made in order to eliminate the above-mentioned defects, and the conventional return conductor is functional! Since the method was such that the voltage drop 1 caused by the flow through the conductor itself always appeared on the line υ, an insulation level several steps lower than that of the high-voltage transmission line was sufficient in terms of design. However, the present invention raises this TL to the same insulation class as the high-voltage transmission line.
By installing C, the return conductor can be used in place of the high-voltage transmission line even if one of the current high-voltage transmission lines becomes permanently damaged, and bipolar power transmission can be continued. The purpose of this project is to provide a one-line IH power transmission system that can be used as a source of electricity.

Once the main hunting operation is started, the power transmission system will be activated.
tJ, $ It is now possible to continue the same bipolar operation as before the failure, and even if one of the bipolar high-pressure transmission lines suffers a permanent accident, there will be no increase in transmission line damage or transmission line losses ( It is possible to maintain the same N current power transmission capacity as before the immediate failure, and it is possible to continue operating the 11 converters in good condition during operation.

力と内済透型じとつ１大変顕著力効果がある。Accordingly, 1. In the present invention, in a new bipolar surface pumping system with a return conductor, the return conductor has the same insulation level as the high-voltage transmission line, and is equipped with a switch for switching the transmission line. In particular, even if one of the bipolar DC high-voltage transmission lines becomes permanently unusable, the return conductor can still be used as a substitute for the high-pressure transmission line, and bipolar operation can continue. I can use it 1@
The reliability of the transportation system, the power of the same as the utilization rate of the work, and the same as the internal settlement type have a very significant effect.

When applied to AC transmission I-line and used as a direct R transmission line, there are three transmission lines with the same insulation level in pairs, so the cost is high (there is no need to worry about two being connected). .
