Evaluation of low voltage ride-through capability of synchronous generator connected to a grid

The grid compliance of generators has been largely focused on wind power generators in literatures. With the increase in installation of distributed power systems, the dynamic performance of governor controlled prime mover driven generators might be affected. This paper discusses the Low Voltage Ride Through (LVRT) compliance of a governor controlled generator connected to a ring structure transmission system. The LVRT compliance of the generator is examined through case studies for various scenarios. This simulation study implies that a particular prime mover driven generating unit may be able to comply with the LVRT requirement in one grid code, but may fail to comply with the LVRT requirement in another grid code.
