High-Frequency Resonance Evaluation and Suppression Measures for Receiving-End of Kun-Liu-Long DC Project

Abstract

Abstract: The voltage source converter is prone to negative damping in the high-frequency harmonic band, thus causing resonance phenomena. The Kun-Liu-Long DC project, as a UHV multi-terminal hybrid DC transmission project, needs to evaluate and analyse the high-frequency harmonic resonance risk of its flexible DC converter stations in Liuzhou and Longmen. Based on the impedance analysis method, an analysis is made of the impact of control link delay, feedforward filtering and controller parameters on the change trend of AC impedance of flexible DC converter stations. 22 and 34 AC line operating conditions are considered respectively, and the AC system harmonic impedance scanning calculation is carried out for various operating conditions of Liuzhou Station and Longmen Station at the receiving ends. To avoid resonance, a 100 Hz low-pass filter should be added to the feedforward of the gantry station, with a control link delay of 300 μs, which will affect the dynamic response performance. The corresponding high-frequency harmonic resonance risk suppression method is proposed, which can provide a reference for suppression of the high-frequency harmonic resonance risk of the Kun-liu-long DC project.

Key words: Kun-Liu-Long DC project, high frequency harmonic resonance, harmonic impedance scanning, flexible DC, risk suppression method
