METHOD FOR CONTROLLING OPERATING CONDITIONS OF D.C. TRANSMISSION LINE AND CONTROL DEVICE FOR EFFECTING SAME According to the invention, the method for controlling operating conditions of a d.c. transmission line consists in maintaining a predetermined current value at a first substation by controlling voltage at that substation, while at a second substation voltage is controlled to maintain an extreme value of a certain controlled variable dependent on the operating conditions at said second substation and formed as a function of parameters which, when reaching an extreme value, ensures a maximum possible voltage at that substation, while maintaining the predetermined current value. The method is effected with the aid of a control device comprising a controlled variable former, an adder, an automatic controlled variable optimizer and a control action discriminator. |
