摘要:阐述了一种以单片机为控制芯片的嵌入式新型无功补偿装置,该装置的工作原理是通过电压电流相位差的比较,获得系统的功率因数,经过嵌入式系统对数据的分析与处理,判定是否需要进行无功补偿,决策投切无功补偿设备,系统所使用的无功补偿装置是通过交—直—交整流逆变电路改变电压激励形式,使同性负载之间相互无功补偿,达到容性无功补偿效果。具有推广应用的价值。

Abstract: This article expounds a with the single chip processor as the main control chip embedded new pensation devices, The device's working principle is through parison of the voltage phase difference, Get the power factor system, After the embedded system analysis of the data and processing, Decided whether or not to make the reactive pensation, The decision to cut shots of reactive pensation equipment, System used by pensation device is through the pay-straight-/ rectifier voltage inverter circuit change incentive form, make same-sex load each other between the reactive pensation, achieve capacitive pensation effect. Has the application value.
Key words: Embedded system ;reactive pensation; inductance; power factor ;power system; rural power grid
