摘　　要：给水深度处理工程大量使用变频器等非线性设备,电流总谐波畸变率较高。根据标准图集(11CD403)中的参数及计算方法,采用有源滤波进行谐波治理。实际测试时发现标准图集中提供的参数及计算方法有不足之处,如水处理工程典型THD i偏低、消谐式无功补偿无法投运、有源滤波投运后谐波电流放大等情况,需进行优化。为此,提出优化方法,并利用谐波电流计算法进行谐波治理计算。Nonlinear equipment such as frequency converters are widely used in advanced water treatment projects.The total harmonic distortion rate of current is very high.According to the parameters and calculation methods in the standard drawing set(11CD403),use active filter to control harmonic.During the actual test,it is found that there are deficiencies in the parameters and calculation methods in the standard drawing set(11CD403).For example,the typical THD i of water treatment project is low,harmonic elimination reactive power compensation cannot be put into operation,harmonic current will be amplified after active filter is put into operation.The standard drawing set(11CD403)need to be optimized.This paper proposes an optimization method.Harmonic current calculation method is used for harmonic treatment calculation.
