HVDC POWER TRANSMISSION. THE TECHNOLOGICAL RESURGENCE OF DIRECT CURRENT

Power limitations of the HVDC Transmission Power System

The scope of the presented paper is concentrated on two terminal HVDC transmission system. The intention of the paper is to present a precise insight into the limitations of the transmitted power of a HVDC system incorporated in real AC power system. The paper demonstrates the impacts of the combined AC/DC system model parameters on the transmitted power through the DC link. Also, in this paper...

Capacitor Commutated Converters for High Power Hvdc Transmission

Two concepts for the transmission with a high power capacity using HVDC technology are analysed in this paper. The technology of Capacitor Commutated Converters (CCC) is presented and the design of two system models is described. Their steady-state as well as transient performance is presented and the CCC is compared to the conventional HVDC transmission. The advantages of the CCC for high powe...

HVDC Transmission with STATCOM

Most of the HVDC power converters with thyristor valves are assembled in a converter Bridge of Six pulse configuration. Converter transformers with one DC side winding as an ungrounded star connection and the other a delta configuration. Comparative studies of the two systems of HVDC CIGRE model without STATCOM and with STATCOM were performed. In these case, the consideration was the converter ...
