摘　　要：在分析传统补偿方案的优缺点后 ,提出一种以 80 31单片机为核心的无功自动补偿综合判据新方案。该方案以电网功率因数作主判据 ,电网无功电流余量和电压作辅助判据 ,从而实现了电容器自动循环投切并使无功缺额最大限度的补偿。彻底消除了在电网功率因数及负荷变化的整个范围内投切振荡现象的产生。Analyzing the advantage and disadvantage of the traditional compensation design, this paper presents a new synthesis judgement design of reactive automatic compensation, which takes 8031 as the core of controlling. Power factor is the main judgement, and reactive current surplus and voltage are the auxiliary judgements in the scheme. So, capacitor can be switched periodically and automatically, and shortage of reactive can be compensated maximally. Switch oscillation is eliminated completely even power factor and load of electric network are changed in their whole range.
