Research on Wave-Trapping Method for Incentive De-icing of Power Transmission Lines
摘要
Abstract
High frequency high voltage excitation de-icing is a kind of methods of realizing the transmission line on-line power de-ic-ing, using this de-icing technology on transmission line, the excitation device produces both a higher fequency harmonic wave for de-icing and a low harmonic waves because of the internal excitation power electronics.This paper designs a set of line resistance wave method for 18 kV/40 kHz high-frequency high-voltage de-icing technology, the high-frequency wave traps access at the transmission line ends, using the principle of single frequency allowing only 40 kHz high frequency signal through in the line of de-icing to ensure the high frequency de-icing.The active power filter is used to suppress the low-order harmonics because of the internal excitation pow-er electronics to ensure the quality of power transmission.By simulation, the correctness of preventing wave method for high-frequen-cy high-voltage de-ice lines was verified.关键词
