Project background
Quality and technical supervision is an administrative activity that regulates and supervises product quality based on laws and regulations, standards, and technical inspection and measurement. Quality and technical supervision work is an important and comprehensive basic work, covering a wide range of areas, involving various fields of national economy and social development, including industrial and agricultural production, engineering construction, scientific research, cultural education, medical and health, environmental protection, nuclear safety, domestic and foreign trade, and service industries, as well as all aspects of people's lives.
Electricity overview (testing and inspection equipment, central air conditioning)
Currently in the central distribution room of Hunan Provincial Quality and Technical Supervision Bureau,there are 3 transformers, 10kV/0.4kV. The rated capacity of transformer 1 is 1000kVA, with a voltage level of 10kV/0.4kV, mainly loaded with fiber cotton inspection and testing equipment, LED lights and lighting, and office equipment; the rated capacity of transformer 2 is 1000kVA, with a voltage level of 10kV/0.4kV, mainly loaded with food inspection and testing equipment, LED lights and lighting, and office equipment; another transformer has a rated capacity of 1600kVA, with a voltage level of 10kV/0.4kV, mainly loaded with central air conditioning, LED lights, data center, and corporate database;Currently facing low power factor and high harmonic content..
Design plan
Foreach transformer design1 setlow voltageActive filter deviceAPFGD, improve power factor, filter characteristic sub-harmonics, stabilize system voltage, improve power quality, and ensure power safety.
Active filter deviceEffectanalysis
Through the active filter deviceAfter the operation of the APFGD device, the system power factor increased from around 0.46 to above 0.95, and the total harmonic distortion of the current decreased from 16.8% to 0.8%, solving the power quality problem for users.
