Shenzhen Xinming Hospital is a high-level affiliated hospital jointly established by Shenzhen Municipal Government and Sun Yat-sen University in Shenzhen. Located in Guangming New District, planning 4,000 beds to meet the local people's medical and health needs, but also to a large extent as a teaching hospital to undertake the role of Shenzhen University medical personnel training.


Customers encounter power quality problems:

The hospital power distribution system is generally 10kV / 0.4kV transformer, the main load for the electronic medical precision equipment, lighting, inverter ventilation equipment, computers and UPS most of the non-linear devices.

Mainly 3,5,7 harmonic, THDi at about 30%. A large number of non-linear load will cause unbalanced three-phase, harmonic excessive, neutral line harmonic current overload power quality problems, a direct impact on the normal operation of medical equipment and precision equipment.

Active power quality control with active filter + dynamic reactive power compensation / filtering device.

Product solutions / service options: APF + components

Product Operation User Certification and Governance Results:

After the APF and its components were turned on, the main 3rd, 5th, 7th, 11th, 13th, 17th and 19th harmonic contents in the system were significantly reduced, the higher harmonics were basically eliminated, and the current distortion ratio (THDI) % Down to 5%, the total harmonic current eventually dropped within 20A, the compensation effect has also reached the requirement, a good solution to the problem of power quality in distribution.
