中频电炉的谐波治理

中频电炉负载在电网中产生较大的谐波电流,对电网的安全运行会产生严重影响。单调谐滤波器为容性,而中频电炉工作一般功率因数较高,因此对中频电炉的谐波治理,应兼顾滤波与无功功率补偿。根据单调谐滤波器的设计原理,设计了一套计算软件,可以理论计算出滤波器投入运行后的谐波滤除率及目标功率因数值,使过补偿得到有效控制。多项工程实践证明是切实可行的,实际应用也取得了良好的效果。

Power Filter for Intermediate Frequency Electric Cooker

The load of intermediate frequency electric cooker can cause much current harmonic. It can affect the running of the electric network. Single tuned filter is made of capacitance. But also it's power factor is higher. So power filter is designed for it must think over the filtering power and reactive power .According to the theory of designing for single tune filter, a suit of software is designed. It can figure out the rate of remove for current harmonic and power factor theoretically, and effectively contr...
