Automatic Voltage Regulation of a Generator synchronized with Grid. Design and Implementation of an Automatic Synchronizing and Protection Relay.

      Аннотация: With the increasing energy demand, it has become necessary to employ small scale distributed generators to different power generation sources and merge the power in one stream. Distributed generation is widely being used so the theme of this book is to automate the existing manual synchronization of a Distributed Energy Resource (DER) to the Main grid. The document covers the details of synchronous generator synchronization i.e. needs, conditions, techniques, procedure, advantages, modelling and design options for synchronization. In the synchronization process, firstly frequency synchronization is automated via speed synchronization. For the implementation of design, LabVIEW software is used. In the next phase, Automatic Voltage Regulation (AVR) has been achieved using Arduino along with LabVIEW and an eight channel relay. Finally, protection schemes against over current, over frequency, under frequency and under voltage of the generator have been designed.
