2019-07-13
After the operation of the dynamic capacitor compensation cabinet - low-voltage automatic reactive power compensation and harmonic suppression device MSCGD, the system power factor improved from around 0.44 to about 0.92, and the system current decreased from approximately 1250A to 840A. This solution addresses the user's power quality issues, saves over 10% on electricity costs, improves the power factor, suppresses harmonics, and reduces system current, enhancing the quality of electricity usage.
Customer: Hunan Hengyang Ruida Power Co., Ltd.
Project Background
Hunan Hengyang Ruida Power Co., Ltd. is a manufacturing enterprise specializing in solar energy storage colloidal batteries and environmentally friendly valve-regulated sealed lead-acid batteries, with a business scope that includes lead plates, batteries, chargers, solar power generation systems, chargers, and related equipment; mainly applied in solar and wind energy storage systems,UPS backup power communication systems, automatic control systems, etc.
Overview of Electricity Consumption (Electroplating)
Hunan Hengyang Ruida Power Co., Ltd. has a new workshop with3 transformers, where 3 workshops are equipped with 1 transformer with a rated capacity of 1250kVA, 4 workshops are equipped with 1 transformer with a rated capacity of 1600kVA, and 6 workshops are equipped with 1 transformer with a rated capacity of 1600kVA, with a rated voltage of 10kV/0.4kV, and the main load is charging equipment. The power factor ranges from 0.3 to 0.75, and due to the low power factor, the utilization rate of the transformer is low, causing transformer overcurrent, noise, and temperature rise, and even total circuit breaker adjustment phenomena.
Dynamic capacitor compensation cabinetDesign Plan
Design 1 set for the low voltage side of each transformer1 setDynamic capacitor compensation cabinet-Low voltage automatic reactive power compensation and harmonic suppression deviceMSCGD, to improve power factor,suppress harmonics,reduce system current, and improve power quality.
