National Exhibition and Convention Center(Shanghai) is the largest complex of single building and exhibition in the world. Located in the Yangtze River Delta, National Exhibition and Convention Center(Shanghai) serves China and the world with breakthrough planning and design combined with perfect service functions, which is suitable to be used as a venue for business promotion, theatrical performances, forum annual meetings, cultural exhibitions, fashion entertainment and other activities. The main loads of National Exhibition and Convention Center(Shanghai) are elevators/escalators, water supply system pumps and air-conditioning fan inverters, office and computer networks, UPS power supplies, and electronic lighting. These loads will generate a large amount of harmonics during use, which may become a disturbance source that causes harmonic distortion in the low-voltage power supply system, causing pollution to the power distribution system, and even causing harm to the surrounding communication system and even equipment other than the power distribution system.     Faced with the power quality characteristics of the National Exhibition and Convention Center(Shanghai), YT Electric provides customers with customized low-voltage electrical system solutions: 400A Active Harmonic Filter Cabinet in order to ensure the continuous and reliable operation of the automation equipment that has been under high load for a long time, and to improve the stability of the operation of the exhibition center. The Active Harmonic Filter(AHF) device uses advanced power electronic technology to detect the harmonics in the power grid in real time. It also generates an inverse compensation current through the converter to dynamically filter out the harmonics in the power grid. The following is the outcome. After the treatment of the YTPQC-AHF Active Harmonic Filter device, the current waveform is well improved and the harmonic current distortion rate is reduced from 34.7% to 1.5%. YT Electric Co. has effectively reduced the harm of harmonics and ensured the smooth development of various activities in the Convention and Exhibition Center. It also verified the safety, reliability and efficiency of YT Electric's Active Harmonic Filter once again.   Current waveform before compensation Current waveform after compensation Current distortion rate before compensation Current distortion rate after compensation Reactive power and power factor before compensation Reactive power and power factor after compensation
