Effect of parallel section and lines in parallel section on unbalance degree of UHV AC line is important.
- class="label">•
Length and number of parallel section, active power of lines in common corridor have considerable influences on unbalance degree of double-circuit UHV AC line.
- class="label">•
Proper length of parallel section should be chosen, and the number of parallel section and the one of the lines in every parallel section should be limited.
- class="label">•
Ratio of rated active power of lines in common corridor should be at a lower level.
