Abstract

Abstract:

±800 kV Fulong-Fengxian UHVDC transmission system (XSH800 project) has successfully operated for 5 years. Its operation situation in last 5 years was analyzed, as well as the availability index and influence factors. In last 5 years, the cumulative transmission power of XSH800 was up to 895.53 billion kWh； bipolar and unipolar forced outage did not occur； single-valve group forced outage only happened five times； the unavailability of forced energy was only 0.0368%, which reached the international leading level. The practice results prove the safety and economy of UHVDC technology. The equipment problems exposed during operation, which may affect the availability, have been timely and fully corrected, and applied in the subsequent UHVDC transmission project. The successful operation of XSH800 in last 5 years has played a role in the demonstration and promotion for the large-scale construction and rapid development of UHVDC transmission project.

Key words: UHVDC transmission, XSH800, availability, operation
