To improve the energy-saving detection ability of traction-type elevator,a method for detecting the energy-saving effect of traction-type elevator based on virtual instrument is proposed.An analytical model of energy-saving parameters of traction-type elevator was constructed,and the energy distribution relationship of traction-type elevator driven by induction motor was obtained by combining non-sinusoidal excitation loss analysis method.According to the energy distribution relationship,the functional relationship between the energy-saving parameters of the traction-type elevator and the residual loss formula was analyzed,and the biased small hysteresis parameters of the energy-saving effect of the traction-type elevator were derived by using the simplified static Preisach model.Considering the offset small hysteresis fusion parameters,the power loss and power gain parameters of traction-type elevator were obtained by detecting the peak point of phase current.The motor torque information parameters of AC traction-type elevator were obtained through an Energetic hysteresis model.According to the results of parameter estimation,the energy-saving effect of traction-type elevator was detected.The experimental results show that the above energy-saving effect detection method of traction-type elevator has good reliability and detection performance and can improve the visual interaction and management ability of energy-saving effect of traction-type elevators.
