(I) Product Overview

MAPF active power filter is a new type of power electronic equipment developed by Chengdu Mellon Electric Co., Ltd. using domestic and foreign technology and research results, which is used to dynamically suppress power harmonics and compensate reactive power. Suitable for 380V ×(1±20%) voltage system, it is the perfect solution for harmonic control. The device uses the current advanced dynamic suppression of power harmonics, reactive power compensation to eliminate power grid harmonics, through real-time detection of the current waveform generated by the nonlinear load, the separation of harmonic components, its reverse, the size, the direction of the opposite harmonic current into the grid, to achieve the function of filtering harmonics. In addition, the device can also provide reactive compensation current to improve power quality, improve the efficiency of power supply equipment, and reduce grid losses.

(II) Use of Products

A commercial plaza in Chengdu takes "experiential commerce" as its core. Under the core connotation of inheriting a city brand of "youth, fashion, trend and taste", its overall positioning is "JOY CITY JOY PARK, the first domestic recreational shopping park". The project is located in a road in Chengdu, with a total construction area of 400000 square meters, including Grade A boutique office buildings, large shopping centers and theme blocks.
