Development of low voltage ride-through capability curve for grid connected diesel engine generators

摘要

Low voltage ride-through (LVRT) is mandatory required in many recent revised grid codes and technical rules for distributed resources, including diesel engine generator, connected to the power systems. Research works for LVRT compliance and capability enhancement have been largely concentrated on to wind power generator. However, not much research works have been published about LVRT assessment of a diesel engine generator. Diesel engine generators are increasingly becoming important for power system and smart grid. This paper presents the development of LVRT capability curve and the assessment of LVRT compliance for a diesel engine generator. The possible methods for LVRT capability enhancement are briefly discussed in the paper as well.
