Dynamic Exponential Load
Description:
This device is an implementation of the three-phase exponential load model. The load active power and reactive power vary as function of its voltage amplitude and frequency. This device is implemented... see more as described in [1]. It allows to perform classical and sophisticated dynamic-stability studies in EMTP. This device can be used in the load flow and time-domain simulations.
During the load initialization, the initial active power and initial reactive power are used to find the load-flow. The load voltage magnitude and phase with update from the load flow results automatically.
