Abstract
- At present, China’s energy distribution and economic development are extremely unbalanced. In order to make rational use of resources, China has promoted the “west to East power transmission” and “north to South Power Transmission” pattern. HVDC transmission has obvious advantages in this long-distance transmission, but there are some shortcomings in the traditional LCC-HVDC system. Therefore, a new system LCL-HVDC is proposed. Firstly, some advantages of the system are introduced; secondly, LCC-HVDC and LCL-HVDC models are built in Simulink, in which the current distortion rate of valve side winding of converter transformer is measured; finally, compared with LCC-HVDC, the loss of LCL-HVDC converter transformer is studied by using method 2 recommended by IEEE standard, and the kn value of the new system is calculated.
