摘要
分析智能电容器的工作原理,设计一种基于DSP的新型低压智能电容器。硬件上以TMS320LF2812为主控模块,采用具有过零投切功能的MOC8083和复合开关组成电路来实现电容器的投切,并可通过RS-485通信网络对多台电容器进行投切控制。软件上使用快速傅里叶变换算法对电网参数进行分析和计算,根据计算参数选择投切方式。
The working principle of intelligent capacitor is analyzed and a new type of low voltage intelligent capacitor based on DSP is designed in this paper.With respect to the hardware,using TMS320LF2812 as the main control module,we realized the switching of capacitor by constructing a circuit that consists of MOC8083 and compound switches with zerocrossing switching function.The switching of multiple capacitors can be controlled through the RS-485 communication network.With respect to software,the fast Fourier transform algorithm is used to analyze and parameters,and the results are subsequently adopted to select switching mode.
