摘要
针对感性负载被低压用户广泛使用并消耗大量无功电能且抄表困难的现象,利用编码技术设计了具有低压无功补偿功能的电力载波智能抄表系统,给出了各组成部分的原理与硬件实现方案。在电能计量部分加入无功补偿单元,实现分户就地补偿,解决了不同电压等级间信号的传输,扩大了传输距离。实际应用表明,系统在大大减少工作量的基础上,提高了用电效率,降低了输电线路的损耗,实现了低压电网的智能化。
Aiming at the situation of inductive load is widely used by low voltage consumers,while large amount of reactive power energy is expended and meter reading is a difficult job,by adopting encoding technology,the smart meter reading system with low voltage reactive power compensation for electric power carrier has been designed.The principle of each composition and hardware implementation are given.In power metering section,reactive power compensation unit is added to realize local compensation for each household for resolving signal transmission among different voltage levels and expand transmission distance.The practical application shows that the electricity usage efficiency is enhanced and the loss of transmission lines is reduced,while labor is greatly decreased,thus intelligent low voltage power grid system can be implemented.
