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:
GoodPower
从图可以看出,滤波器投入之前电网谐波电流很大,总谐波电流畸变率最大高达75.8%,电网电流波形也严重畸变,而对比滤波器投入后可以看出,总谐波电流畸变率最小已降至24.4%,电网电流波形也较之前更接近正弦波,电网电能质量得到了有效的改善,
