| Abstract: | Combining with the latest research finding in the technology and economy of UHV AC/DC power transmission,using minimum annual cost method the economy of two kinds of power transmission systems,i.e.,UHV half-wavelength AC transmission(UHV HWACT) system and ?800 kV DC power transmission system,are researched by multi scheme comparison and sensibility analysis.The critical conomic transmission capacity of UHV HWACT and upper limit of additional control cost are given,and the transmission economy of UHV HWACT and that of ?1?000?kV DC transmission are compared.By use of reliability assessment,quantitative and qualitative reliability assessment of the two transmission schemes are performed. |
