摘要:Asynchronous motors are important loads in power systems. Motor performance has a great influence on a power grid, especially during the motor transient process such as voltage recovery after a grid fault cleared. In this paper the voltage-sag caused by motor dynamic is analyzed and an estimated formula is deduced on the system parameters to the degree of voltage sag. Then the phenomenon of delayed voltage recovery is simulated based on a power system model via MATLAB/SIMULINK to show the influence of system and motor parameters to the degree of voltage sag and low voltage dwell time.
