Based on the latest research results on technical economy of UHV AC and DC transmission, the economic comparison of two kinds of transmission schemes for UHV half-wavelength AC transmission system and ± 800 kV UHVDC transmission system is carried out by using the minimum annual cost method. The critical economic transmission power and the upper limit of additional control costs for the UHVAC half-wavelength AC transmission system are given. The transmission economics of UHVAC half-wavelength AC transmission system and ± 1 000 kV UHVDC transmission system are compared. The reliability assessment methods were used to evaluate the reliability of two kinds of transmission schemes for UHVAC half-wavelength AC transmission system and ± 800 kV UHVDC transmission system.
