摘要
针对电力系统中存在大量谐波污染问题,考虑到有源滤波器价格昂贵,目前主要应用于低压场合,传统无源滤波器存在电容器参数受环境影响导致滤波器偏离谐振点的缺陷,试制了基于可变电抗器的无源动态谐波滤波装置.研制一种处理速度快,实时性高,控制精度高,稳定性好的基于单片机的无源动态谐波滤波控制器,替代原有PLC控制器.该滤波装置能够实时滤除电网中的各次谐波,有效改善供电质量.
Abstract
In view of so much harmonic pollution problems in the power system, considering the high expense of active power filter, and it mainly be applied in low voltage occasion at present, the capacitor's parameter will be affected by the environment and lead to the filter deviate from its resonance point, a conventional passive power filter exists this defect. Trial-produced a passive dynamic power filter device, it is based on the variable reactor. Developed a passive dynamic power filter controller based on MCU to replace the original PLC controller, it has high processing speed, high real time, high control precision, well stability. This filter device can filtering each harmonic in power network and improve the quality of power supply effectively.
