Abstract :
Results are presented of field tests which were part of an EPRI-sponsored project to develop advanced control techniques for the design of HVDC modulation systems. The objectives of the tests were to validate the digital control design models for the rectifier and inverter controllers which were developed from a digital large-scale model of the power system and to assess the dynamic environment in which the modulation control system must operate. The field tests and digital model results confirm a dominant interarea mode of oscillation of 0.8 Hz. Field tests also established spurious responses in rectifier and inverter frequency measurements, which appear to be attributable to transducer distortion
