摘要
为减少目前电力系统中的谐波与无功功率污染问题,提高电能的有效利用率,设计了一种能够去消谐波次数达31次和补偿无功功率的并联型智能化数字有源电力滤波器。简述了本系统的滤波原理和所要实现的功能,阐明了与液晶显示相结合的硬件和软件设计及多处理器之间的通信协议规范;原理样机的试验结果表明本设计能够达到所要求的技术指标。另外,软硬件设计为以后的二次开发预留了良好的接口。
To reduce the harmonics and reactive power pollution and improve the effective utilization of energy,an intelligent digital shunt active power filter is designed,which can eliminate harmonic up to 31 times and reduce the reactive power.Test results show that the principles of this system and the filtering functions are implemented.The design of the hardware and software with the liquid crystal display and the communication protocol in the multi-processor are described.Develop prototype test results show that the system meets the requirment of technical specifications.In addition,the hardware and software design provide a good condition for the future secondary development.
