Active protection method and system for internal fault of converter transformer on-load tap changer

PendingCN122292267AAvoid false alarmsAvoid false trippingStart timeElectrical polarity
An active protection method and system for internal faults in an on-load tap changer of a converter transformer includes: determining the start time of on-load tap changer operation and then extending the time interval; identifying ultra-high frequency (UHF) and high frequency (HF) pulse signals and discharge pulse times exceeding a set threshold within the extended time interval; identifying whether the on-load tap changer is adjusting a polarity-crossing or non-polarity-crossing tap position; determining the internal abnormality of the on-load tap changer based on the UHF and HF pulse signals and their pulse times during operation; and further issuing "general alarm," "serious alarm," or even "protection trip" signals based on the severity of the internal partial discharge detected by the UHF and HF signals. This invention fundamentally avoids false alarms and trips in monitoring or protection devices caused by discharge during normal tap changer operation. Furthermore, it achieves a leap from "passively preventing false operation" to "actively detecting faults," proactively preventing damage to the on-load tap changer itself or even transformer explosions caused by its faults.

This invention discloses a blind estimation method for frequency-hopping signal parameters based on atomic features. The method involves: first, windowing, compressed sampling, and atomic feature extraction of the frequency-hopping signal; then, roughly estimating the hopping time based on the distribution of atomic features within different windows; next, precisely estimating the hopping time, hopping period, and hopping speed using a block-diagonalized Fourier orthogonal matrix; and finally, estimating the frequency of each hop signal using an orthogonal matching pursuit algorithm, and obtaining the frequency-hopping pattern of the entire sample by concatenating each hop signal. This invention can adjust the search step size and compression ratio to change the computational complexity and estimation accuracy, adapting to different signal-to-noise ratio (SNR) environments. In high SNR environments, increasing the search step size and compression ratio effectively reduces computational complexity, while in low SNR environments, decreasing the search step size and compression ratio effectively improves estimation accuracy.
