Military Industrial
Background:
4 1000kVA transformers, with 3 of them periodically operating at full capacity, but the actual average load rate is only 52%
Solution effect:
Using secondary flexible interconnection, achieving load balance and smooth transition, increasing the overall load capacity to 78%, and enhancing transformer configuration capability by 50%, without reaching full load conditions for the transformers.
Mechanical Machining Enterprise
Background:
The entire plant has four 10kV 2500kVA transformers, operating continuously for 24 hours, with predominantly short-cycle loads, averaging 45% of the rated capacity. Some transformers have periodically reached saturation.
Solution effect:
Shutting down one transformer and implementing secondary busbar flexible interconnection for the remaining three transformers, resulting in an annual savings of 750,000 RMB in fixed electricity costs. The investment will be recovered within 1.5 years.
Pharmaceutical Company
Background:
Two substations with a total of five transformers, operating on an eight-hour shift basis, with an average load rate of approximately 25%, and fixed electricity fees calculated based on peak demand.
Solution effect:
Offering flexible interconnection with energy storage brings two main benefits: 1. Reducing the average peak demand by 500kW, resulting in an annual saving of 210,000 RMB in capacity charges. 2. Taking advantage of off-peak electricity rates, leading to an annual cost savings of USD46,200.
