With the westwards and northwards expansion of the exploitation of energy resources in China, the distances between the resource and load centers become farther, and the development of the high efficient, large capacity long distance power transmission technologies is urgently necessitated. Firstly, the converter units in the main circuit of converter system for ±1 100 kV UHVDC power transmission project and their combination patterns are analyzed, and it is pointed out that the double 12 pulse converter unit connected in series for single pole is a relatively optimized topology; secondly, the optimization design of key parameters of inversion system for ±1 100 kV UHVDC power transmission project from East Junggar to Chengdu, such as DC inductive voltage drop,no-load DC voltage and its limit and so on, is analyzed;finally, the key parameters of main equipments such as converter valves and converter transformers in converter system are calculated. Results of above-mentioned analysis and calculation are available for reference to the development and manufacturing of main equipments for ±1 100 kV UHVDC power transmission projects.
