单片机应用系统设计—功率因数补偿器
摘要
根据目前低压电网用电负载功率因数偏低和国内单片机的应用现状,立足于补偿装置提高交流电的功率因数,基于将每个补偿进行集中监控、信息集中传递的思路,本文作者在分析现有的控制系统体系结构的基础上,提出了基于单片机的功率因数补偿器设计,构建了功率因数智能动态补偿系统。针对本系统的应用对象,确定了本系统中所应用的无功电流实时检测理论和方式、补偿电容器接线和分组方式、补偿电容器投入时刻的选择等关键技术;在分析电网的频率特性和功率因素动态补偿系统的性能特点基础上,对功率因数动态补偿。系统以性价比很高的8031 单片机作微处理器单元,该单片机具有当今最新型的片内闪速可编程、可擦除的存贮器,最多可擦写1000次。他不仅具有MCS- 51 系列单片机所具有的特性,而且还有完善的兼容性、快捷便利的电擦写操作和价格低廉的特点,此外他还可加密,因此广受用户欢迎。

ABSTRACT
Use the applied present condition of a machine of the electricity load power factor currently according to the low-pressure charged barbed , have a foothold to equip the power factor of raise the alternate current in the repair, according to carry on each repair concentrated supervision, information the way of thinking that concentration deliver, this text in analyzing the foundation of the existing control system structure, the author put forward according to the power factor of a pensate machine design, set up the power factor intelligence dynamic state repair at the applied object of this system, make sure this system in applied without electric current of the solid hour examines the theories and ways pensates the capacitor to connect the line and cent a method, compensate the capacitor throws in the choice of the time etc. key pensate the function characteristics foundation of the system in the frequency characteristic and power factor dynamic states of the analytical charged barbed up, compensate to the power factor dynamic system is with sex pare very high 8031 single puter to make the microprocessor unit, should a machine tool have nowadays the latest model inside the slice soon programmable, can wipe in addition to of save the machine , can wipe to write at most 1000 not only has the MCS- 51 The characteristic that a machine of series have, and still is perfect and permit the ele
