A HVDC transmission line carrying electric power from power plants in remote areas to urban areas transmits electric power always in the same direction. In such a case, the thyristor valves at the rectifier station can be replaced by diode valves. Although diode valves are less expensive than thyristor valves, the former may be inferior to the latter from viewpoints of valve control and protection. Various control and protection characteristics of the HVDC line using diode valve converters are discussed, such as abnormal voltage suppression in starting condition, coordinated control of the generator and HVDC line, reduction of ground fault current, quick restart, fault protection, etc. It is concluded that the HVDC system using the diode converter as rectifier is promising when the dc power is transmitted only in one direction.
