| Abstract:
After systematic investigation on current technical level of counter-interference capability of communication networks and lines in China and present situation of related standards being executed and on the basis of summarizing bygone research results, standard and design specification related to the influence of power transmission lines on communication as well as the implementation of these results in practice, by means of theoretical calculation, probability analysis and simulation tests, the interference restriction level that the communication networks can withstand is proposed and the limitation value of DC equivalent disturbing current (EDC) suitable to counter-interference level of current communication networks is given. The harmonic current restriction standard for UHVDC project from Xiangjiaba to Shanghai Nanhui is analyzed and the recommended value is put forward. On this basis, a typical design scheme of DC filter for UHVDC project is proposed. Results of laboratory tests and on-site measurements show that the proposed harmonic current restriction standard is suitable for engineering construction and by which both the seized land area and engineering cost can be saved. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||
