SCE solved engine part-load emissions problem on Catalina Island using NAS
|Owner||Southern California Edison|
|Commissioning Operation Date||August, 2011|
- Catalina Island is powered by diesel engines. NOx emission regulation can only be met when engines running at 80 to 100 percent capacity.
- A solution was needed for those times when Catalina required energy from part-load (< 80%) engine capacity.
- When demand is low, the diesel engines charge NAS.
- NAS supplies energy when additional engines cannot operate at rated power.
- Improved system voltage regulation, system stability, and system reliability.
Simulated System Operation on Catalina Island
- System operation of a day on Catalina Island utilizing NAS was simulated.
- Output power of Generators can be maintained at their allowable operation range (at 80 to 100 percent capacity) utilizing NAS.
