电压型有源电力滤波器在化工行业谐波治理中的应用

Application of voltage APF for harmonic treatment in chemical industry

分析了电力电网的谐波源、谐波特性和谐波产生的危害,并通过在某大型化工公司低压配电系统中的实际应用案例,研究了电压型有源电力滤波器投入前后的数据等情况,说明了有源电力滤波器的谐波治理技术是改善抑制电网污染、提高电能质量、保证电气设备安全运行的有效手段之一。

The harmonic source, harmonic characteristics and its harms for power grids are analyzed. The data before and after the voltage APF input are also given through its practical application in low-voltage distribution system in a large chemical company. It illustrates that the harmonic treatment technology of APF is one of the effective means to suppress the power grid pollution, improve the power quality and ensure the safe operation of electrical equipment.
