摘要
针对低压家庭、小微企业以及农村电网用户,设计了一种数字式电压监视与电压保护装置,开发了基于快速傅立叶变换(FFT)的电压偏差与电压谐波畸变率分析算法,通过仿真,验证了该装置可实现低压用户侧的电压监视和电压保护。
A digital voltage monitoring and protection device is proposed for household,micro enterprise and rural users by MCU and modular design.FFT-based voltage deviation and voltage harmonic distortion computing algorithms are proposed to implement the voltage monitoring and protection for user-side low-voltage.Simulation results show the pro-posed module is expediently applicable.
