A centralized processing method of DC measuring system is used for the UHVDC projects of CSG in the way that the on-site data are transmitted to the control and protection system by the measurement bus ( TDM bus ) after they are pretreated by the measureing system, and thus higher transmission reliability between the measuring system and the control and protection system is needed. This paper describes the configuration of UHVDC project measuring system, and analyses its measurement bus switching logic. The adverse effect of the switching on the protection system is analyzed, and its corrective proposal is put forward.
