Technical and Economic Characteristics of High-Phase-Order Power Transmission.

摘要

In 1978, the US Department of Energy sponsored a project for development of analytical design methods and testing of experimental six- and twelve-phase lines. The objectives were to develop promising design concepts, extend to high phase order the complex predictive and design calculations for radio noise, audible noise, electric fields, and conductor motions, and to demonstrate that practical and economic designs are presently available. The following areas are discussed in this report: (1) structures for the test lines; (2) insulator designs; (3) insulating midspan spacers; (4) power supply substation; (5) high phase order line impedances; (6) corona and field effects; (7) conductor motion due to ice shedding, fault currents, and wind; (8) lightning performance; (9) uprating existing double circuit lines; (10) economics of high phase order; (11) sample line designs; (12) national electrical safety code; and (13) future applications.
