Abstract
With the large using of various power electronic devices and the impact load is increasing day by day
the interharmonics pollution in power system is becoming more and more serious. This paper introduces the measurement method for interharmonics specified in GB/T 17626.7 standard and analyzes the disadvantages of this method in engineering application. On this basis
a multi-window width algorithm for the dominant interharmonics distribution is proposed
which can simply
rapidly and accurately calculate the dominant interharmonics spectrum distribution. The effectiveness of the algorithm is verified by an engineering example
and it is of guiding significance to the engineering management of interharmonics.
