Design and Implementation of an Automatic Synchronizing and Protection Relay through Power-Hardware-in-the-Loop (PHIL) Simulation
This paper focuses on the design and implementation of an automatic
synchronizing and protection relay to automate the synchronization process of a
Distributed Energy Resource (DER) to the Main Grid. The proposed design utilize
a cost-effective data acquisition using arduino in combination with LabVIEW
software to implement the multi-purpose synchronizing relay. The proposed
synchronizing relay is capable of synchronizing a Distributed Generator (DG) to
the power grid from black-start and fulfills the requirements imposed by the
utility. The synchronizing relay is implemented through voltage and frequency
control of an actual lab-scale synchronous generator. In the synchronization
process, frequency synchronization is done using speed control of the stepper
motor as prime mover and voltage synchronization is accomplished using
Excitation Control module through Power-Hardware-in-the-Loop (PHIL) simulation.
In grid-connected mode, active and reactive power controls and protection
schemes for the synchronous generator have also been implemented. The proposed
multi-function relay has been deployed and tested on a lab-scale test bed to
validate the proposed design and functionality.Comment: 6 pages, 14 figures, submitted in IEEE International Symposium on
