摘要

The stalling of highly concentrated constant torque induction motor loads due to system faults may result in fault induced delayed voltage recovery. This state can cause significantly depressed local voltage for several seconds after the fault is cleared and can also lead to widely cascaded system failure. Though there is extensive study conducted within the modeling of motor loads, the dynamic connection between the aggregated induction motor loads and the grid still needs further investigation. In this paper, a dynamic performance model is developed for motor stalling and over heat thermal tripping. Specifically, this dynamic model can be constructed with an energy-like Lyapunov function, and can be incorporated as part of power system dynamic cascading model. The simulation examples are carried out in an enhanced version of the IEEE 57 bus test system, as demonstration for feasibility. This model may be beneficial for smart grid monitoring and planning, as well as energy analysis for power system cascading failure.
