摘要
直接空冷机组厂用电系统大量采用低压变频器,在变频器的进出线侧易产生大量谐波。以某2×600 MW直接空冷电厂为例,对其厂用电系统进行谐波分析计算,根据现场实测数据验证计算结果,并提出直接空冷机组厂用电系统的谐波治理措施。
Many low-voltage converters are adopted in direct air-cooled auxiliary power systems,and a lot of harmonics are produced on the inlet and outlet sides of converters.In this paper,harmonics of direct air-cooled auxiliary power systems were calculated based on a 2×600 MW direct air-cooled power plant;the field measured data validated the calculation results;and harmonic control measures were put forward.
