| Abstract |
This paper evaluated the proper capacity for using the secondary battery energy storage as emergency generator Also, the operation characteristics of according to the load type such as emergency load and large induction motor were analyzed when operating with the energy-storage-system capacity evaluated by the PG method proposed in the building-electrical-equipment-design-standard As a result, estimating the energy-storage-system capacity without considering the characteristics of the large induction, it was impossible to start due to the rapid drop in grid voltage. Therefore, this paper analyzed the capacity estimation method of the energy-storage-system and choosing the start-up type considering the large induction motor. |
