Abstract EN
The traditional polarity comparison based travelling wave protection, using the initial wave information, is affected by initial fault angle, bus structure, and external fault.
And the relationship between the magnitude and polarity of travelling wave is ignored.
Because of the protection tripping and malfunction, the further application of this protection principle is affected.
Therefore, this paper presents an ultra-high-speed travelling wave protection using integral based polarity comparison principle.
After empirical mode decomposition of the original travelling wave, the first-order intrinsic mode function is used as protection object.
Based on the relationship between the magnitude and polarity of travelling wave, this paper demonstrates the feasibility of using travelling wave magnitude which contains polar information as direction criterion.
And the paper integrates the direction criterion in a period after fault to avoid wave head detection failure.
Through PSCAD simulation with the typical 500 kV transmission system, the reliability and sensitivity of travelling wave protection were verified under different factors’ affection.
