资料介绍

针对家庭电路中感性负载需从电网中吸收大量的无功功率而引起电能损耗的问题,设计了一种新型的家庭无功功率智能补偿装置。以阻感负载电路和功率三角形模型为基础,建立了补偿容量的计算表达式。基于RN8209计量芯片和STC89C52单片机为核心,能准确地进行采样和计算,自动进行电容的投切补偿并实时显示补偿效果。利用Proteus、Multisim等仿真软件经过多次的仿真,结果表明:进行投切电容补偿后,家庭电路的功率因数能够达到0.95~0.99,电能损耗的问题得到改善,将为家庭每年节约一定的电费。

Aiming at the problem that the inductive load in the domestic circuit needs to absorb a lot of reactive power from the grid and causes the power loss,a new type of domestic reactive power intelligent compensation device is designed.Based on the resistive load circuit and the power triangle model,the calculation expression of the compensating capacity is established.Based on the RN8209 metering chip and the STC89C52 single-chip microcomputer as the core,it can accurately sample and calculate,automate the cutting compensation of capacitance,and display the compensation effect in real time.After many simulations with Proteus, Multism and other simulation softwares,the results show that after the switching capacitance compensation,the power factor of the domestic circuit can reach 0.95~0.99,the problem of the electrical energy loss is improved,and a certain amount of electricity can be saved for the family every year.
