【摘要】 为了改善电能质量,设计了一种基于71M6515H和双CPU的智能动态分相无功补偿控制器,利用71M6515H解决了系统测量精度问题,DSP完成谐波的计算和电容的投切,单片机完成键盘显示和通讯。文章详细阐述了控制器的硬件结构、控制策略和软件设计。控制器具有谐波分析功能,避免了谐波含量较高时投切电容器时出现烧坏电容器的现象,采用分相补偿技术,保证在三相负载不平衡的情况下使线路的三相无功平衡。通过样机运行表明,控制器具有测量参数精度高、系统配置灵活、稳定性好的特点,满足了用户的需要。更多还原

【Abstract】 In order to improve power quality,this paper designs an intelligent dynamic separated-phase reactive compensating controller based on 71M6515H and double CPU,explains the controller’s hardware structure,control method and software design in detail.The 71M6515H is used to improve the controller’s measure precision,and the DSP is used for harmonic analysis and switching capacitances and the single chip is used for controlling keyboard,LED display and communication.This controller has the function of harmonic analysis which can ensure burn out capacitor when cut-close it at high content harmonic.This controller also has the function of separated-phase compensation which ensures line reactive power equation when it has unbalanced load.This controller is of high measure precision,flexible composing and high stability from the test to reach the user purpose.更多还原
