Abstract:
The complete set design of control and protection system for UHVDC power transmission project is proposed and the full scheme of the design, in which the factors such as global structure of control and protection system, the hierarchy of hardware, its functions and the performance requirements, system interfaces and the platform for software and hardware are fully considered, is given. Meanwhile, the features of this scheme and the technological improvements different from those applied in former HVDC projects are discoursed upon which include new introduced Intel Core DUO microprocessor, replacement of TDM bus and CAN bus with eTDM bus, IN-TIME operation system, two out of three logic of DC protection system etc. The proposed design scheme has been applied in ±800 kV DC power transmission project from Xiangjiaba to Shanghai. |
