摘　　要：在400 V低压配电系统中随着非线性负载的比例逐渐加大,其负载性质发生深刻变化。即使在三相正弦波形的作用下,三相相线电流发生非正弦畸变从而产生高次谐波电流。着重阐述了孟加拉国NG IL250 t/d浮法玻璃生产线工程中采用调谐滤波装置治理高次谐波技术,使出口电压为400 V的三台容量为1370 kW天然气发电机组和三台1 050 kW柴油机发电机组主接线得以简化,使之节约电力设备一次性投资30%以上,并且在技术上确保供电可靠性和用电质量。With non-linear load proportion increasing gradually in low voltage power distribution system, its load property changes a lot. Even under the action of 3-phase sine wave, 3-phase conductor current generates non-sinusoidal distortion, resulting in generating higher harmonic current. This paper describes the technology of control higher harmonic wave by adopting single-tuned wave filter in Bangladesh MG 250t/d float glass production line project. With this technology, it makes main wiring reduced concerning 3 sets of 1370 kW natural gas generating units with outlet voltage of 400 V and 3 sets of 1050 kW diesel generating units, which saves more than 30% of the investment for power equipment and at the same time ensures reliability and quality of power supply.
