Studies designed to evaluate the technical feasibility of multiterminal dc transmission are reported. Of particular interest are the operational strategies and terminal control requirements for multiterminal systems using analytical techniques combined with detailed hybrid computer simulation. Analog computer models were developed and implemented for simplified and detailed simulations of the HVDC converter stations. Digital computer program also were developed for simulation of distribution-parameter HVDC transmission lines and dc circuit breaker configurations. In its final form the detailed hybrid simulation of the generalized three-terminal bipolar system represents a very effective tool for accurately studying a wide variety of phenomena in multiterminal HVDC transmission. Several operating schemes were studied, and control techniques developed for two, three-, and four-terminal dc systems. Satisfactory multiterminal operation may be obtained by extending conventional two-terminal dc control techniques. An increased number of operating terminals generally increases the operating point sensitivity and tends to degrade the dc stability. Preferred operating modes have been identified, and use of multiterminal control improves system dampening and response times, thereby minimizing the need for dc switchgear. An extensive appendix and five references are included.
