Abstract: Introduction was made to the multiple-line connection method of ultra-high voltage (UHV) alternating current (AC)/ direct current (DC) transmission convertor station. Analysis was made to the operation reliability of convertor station, impacts of construction in stages, manufacturing of converting transformer; transport etc factors at AC side. This paper combined with Fujian province special geographic climate environment to carry out analysis verification via adoption of PSCAD electromagnetic simulation software. The result shows that double 12 pulse series connection is a more suitable way of line connection method, it has provided a reference for line connection way from the west Zhejiang to Fujian grid of positive and negative 800 kV, 6 400MW UHVDC transmission system.
Key words: ultra-high voltage direct current transmission; single 12 pulse series connection; two series of 12 pulse connection; two parallel 12 pulse connection
