Help set the home page of natural and cultural geography and history of social life and art character of economic science sports core 5th anniversary NBA users DC transmission technology medical aircraft DC transmission technology has been the development of DC transmission and converter technology (especially in high voltage and high power converter equipment) is closely related to the development of. But in recent years, in addition to promote the development of power electronic technology, due to invest a lot of HVDC project operation, many problems of HVDC control and protection, fault, reliability has become increasingly important. The comprehensive application of many new technologies makes HVDC technology has made new progress.

HVDC transmission system reliability technology editor of this paragraph 1. direct light triggered thyristor Thyristor trigger technology is the key technology of DC transmission, the light triggered thyristor, can save the trigger circuit for photoelectric conversion of the board again. But need the corresponding protection or measuring circuit of thyristor, so the technology is complex,
