Qinhuangdao Boye Glass Co., Ltd.
Typical case of harmonic treatment in glass factory (Qinhuangdao Boye Glass Co., Ltd.) Background of the project: At present, a glass 10kV substation mainly has a transformer with a capacity of 1000kVA and 10kV/0.4kV. The main load is a general AC load, but a high-power inverter is used in air-cooled cooling glass. After the glass is output from the tempering furnace, the fan starts to work. This working process is always cycled. During the operation of the fan, the current distortion of the grid is very high. Governance plan: According to the comprehensive consideration of the field test data, a SPA3-100/0.4 active power filter is selected to compensate the harmonics in the power grid to achieve the purpose of effective harmonic control. Governance effect:
