Claims

[Scope of utility model registration request]

(1) The power of a DC transmission system that is equipped with an AC/DC converter and connects two AC systems is set using a power command setting device, and the set power command value and the above DC transmission system are taken out via a voltage detector. In the constant power control device, a lower limit DC voltage setting device is provided, and a lower limit DC voltage setting device is provided, and the DC voltage value is set to the lower limit. A constant power control device characterized in that a set voltage value set by a DC voltage setter is inputted to the divider as a lower limit value.

(2) It is characterized by comprising a maximum value selector into which the DC voltage value detected by the voltage detector and the output of the lower limit DC voltage setter are input, and the output of the maximum value selector is given to the divider. A constant power control device according to claim 1 of the utility model registration claim.
