Research on Residual Current Detection Method for Dual-Core Magnetic Modulation Based on Kalman Filtering Algorithm
摘要
Abstract
Residual current detection is a key technology to ensure the safe operation of low voltage DC distribution systems.Aiming at the traditional single-core magnetic modulation residual current sensor with low precision and poor anti-interference ability,a residual current detection method based on dual-core magnetic modulation is proposed,and the corresponding simulation model is constructed.The modulated signal of the dual-core sensor is filtered and demodulated by the Kalman filtering algorithm,and the simulation results are compared and analyzed with the single-core scheme.The results show that the detection method has the advantages of even harmonic enhancement,detection range expansion and zero drift suppression,which can provide the effective and improved scheme for the detection of tiny residual current signals in high-current scenarios.关键词
