Project Details

Description

This project deals with conducting analytical studies on a three-phase distribution feeder that includes single phase induction motors using the PSCAD software package. PSCAD is a general-purpose time domain simulation tool for studying transient behavior of electrical networks. LBNL has access to monitored data on several distribution feeders with single phase induction motor loads. A generic distribution feeder model will be built up on the basis of representative typical feeder impedances and placements of single phase motor loads. The boundary condition at the feeder head will be played-in trajectories of the 60Hz voltage wave. Both proposed test trajectories and trajectories from the LBNL library of recorded data will be used to stimulate the model. This model development would then be followed by detailed analysis using PSCAD. The specific objectives of this project are: 1. Develop a PSCAD model for a generic feeder, including explicit representation of single phase motors 2. Examine appropriate models for single phase induction motors and implement them in the PSCAD software 3. Utilize available recorded data available to impose observed transient events on the model in order to analyze its response 4. Examine in detail the impact of a fault on the transmission system at different instants during the sinusoidal cycle, on the performance of the single phase induction motors in terms of their dynamic response and reactive power requirement 5. Develop approaches to represent the behavior of single phase motors observed in a detailed three phase representation of the system on a positive sequence transient stability analysis model
