Generation of Composite Load Protection Profiles for Reliable System Operation
Tang, Yingying.
Motor loads are equipped with protective mechanisms to prevent any damage to the loads in the event of a fault. Accurate representation of dynamic motor loads and their protection schemes is vital for power system planning and operation, especially in understanding systems response moments after a fault has occurred. Existing load models are inadequate to capture the behavior of protection mechanisms which can vary widely between different end-use appliances. This article proposes a methodology ...

Motor loads are equipped with protective mechanisms to prevent any damage to the loads in the event of a fault. Accurate representation of dynamic motor loads and their protection schemes is vital for power system planning and operation, especially in understanding systems response moments after a fault has occurred. Existing load models are inadequate to capture the behavior of protection mechanisms which can vary widely between different end-use appliances. This article proposes a methodology to generate composite protection profiles for commercial building motor loads. Combining knowledge of various protection schemes available in various end-use appliances, with the commercial buildings survey data (from U.S. Energy Information Administration) and typical end-use profiles generated using EnergyPlusTM), composite load protection profiles were generated at one-hour interval over a year, for different commercial buildings in representative cities from different climate zones.
