摘要
分析了电网谐波产生的原因,介绍了电网谐波对电动机、变压器、电容器、通信线路、家用电器及电能计量的影响。给出了治理谐波的主要方法,并指出发展混合式有源电力滤波器是当前电网谐波治理的趋势。
The reason why harmonic is produced in power grid was analyzed.The influences of harmonic in power grid that happen to motor,transformer,capacitor,communication line,home appliance and electric power measure were introduced.The main method to suppress harmonic was given,and it was pointed out that developing hybrid active power filter is the current trend of harmonic suppression in power grid.
