これまで各種の工夫がなされ提案されているが、
いずれも、制御装置が複雑高価になつていると共
に、制御途中で伝送回線が瞬断した際の対策も必
要となつてくる。 However, because the distance between each converter is large, information is generally transmitted via a transmission device, and therefore it is difficult to start, stop, or reverse the power flow of one converter. This may result in delays, making it impossible to secure a current margin and making it impossible to transmit power. To compensate for this transmission delay time,
Various ideas have been proposed so far, but
In either case, control devices are becoming more complex and expensive, and countermeasures are also required in the event of a momentary interruption of the transmission line during control.

ことを目的としている。 This invention was made in order to eliminate such a problem, and the control command is separated into control contents and scheduled control time and stored, transmitted to one of the converters, and converted into a time signal and a time signal by each converter. It is an object of the present invention to provide a control device that can perform simultaneous control at low cost by issuing control commands when scheduled control times coincide.

内容が制御装置９に出力される。 An embodiment of the present invention will be described below with reference to the drawings. In FIG. 2, 100 is a control command device;
1 is a control content storage device, 102 is a control scheduled time storage device, and a clock device 110 and an addition time constant (T
The adder 112 adds the current time and T seconds to the control scheduled time storage device 10.
2. Control content storage device 101
and the contents of the scheduled control time storage device 102 are transmitted to the partner conversion device via the transmission device 131. The numerical values in the clock device 110 and the control scheduled time storage device 102 are compared in the coincidence detection circuit 103, and if they match, the gate of the control output circuit 104 is opened and the contents of the control content storage device 101 are output to the control device 8. The movement of the converter at the other end is shown in FIG. In FIG. 3, 201 is a control content storage device, 202 is a control scheduled time storage device, 203 is a coincidence detection circuit, and 204 is a control content storage device.
210 is a clock device, 132 is a transmission device, and 9 is a control device. The content of the control command transmitted by the transmission device 132 is stored in the control content storage device 201 and the scheduled control time storage device 202, respectively, and the storage content of the latter is compared with the output of the clock device 210 by the coincidence detection circuit 203, If they match, the control output circuit 204 outputs the contents of the control content storage device 201 to the control device 9.
従つて、両端の制御装置８と９には全く同時に
出力が加えられるので、直流変換装置は安定した
運転、停止をすることができる。 Therefore, since outputs are applied to the control devices 8 and 9 at both ends at exactly the same time, the DC converter can be stably operated and stopped.
