Dynamic Load Modelling of Some Low Voltage Devices

This paper presents the results of dynamic load modelling for some frequently used low voltage devices. The modelling of long-term dynamics is performed on the basis of step changes of supply voltage of the heater, incandescent lamp, mercury lamp, fluorescent lamps, refrigerator, TV set and induction motor. Parameters of dynamic exponential load model of these load devices are identified, analyzed and mutually compared.
