| titleOfInvention | Improvements in High Voltage Direct Current Power Transmission Plants |
| abstract | 1,192,419. Conversion systems. ALLM€NNA SVENSKA ELEKTRISKA A.B. 12 Oct., 1967 [13 Oct., 1966], No. 46577/67. Heading H2F. A high voltage direct current transmission system in which the rectifier station 1 and the inverter station 2 are both provided with current regulators 5, 6 is characterized by provision of means to modify the regulation current in the event of a fault on the rectifier. Each regulator is provided with a first input derived from a potentiometer 7, 8 to set the required D.C. operating current, and a second input proportional to the actual direct current derived from a transducer 9, 10 in the D.C. path. The inverter is also provided with a third input from a source 65 to set the current margin. Under normal conditions, the signal derived from transducer 9 is greater than that derived from potentiometer 7 and no output is produced by integrator 58. If due to a fault one of the rectifier units 31, 32, 33 is shunted the current derived from transducer 9 falls below that from potentiometer 7 the integrator 58 produces an output which is fed to both regulators (via inputs 57, 67) to increase the control current by an amount equal to the current margin. The integrator may be replaced by relays, Figs. 2a, 26 (not shown). |
