Abstract

This project is to design IDMT (Inverse Definite Minimum Time) Over current Relay using Arduino. The relay can be used to sense faults in transmission line based on analog to digital conversion of the 3-phase current and when a current in a part of a power system exceeds a pre-set value either due to a fault or a large overload, the relay will isolate the part through sending trip signal to a circuit breaker. The main features which have encouraged the design and development of Arduino based protective relays are their economy, compactness, reliability, flexibility and improved performance over conventional relays.
基于霍尔效应电流传感器的超电流继电器微控制器
本课题是利用Arduino设计IDMT (Inverse Definite Minimum Time)过电流继电器。该继电器可以通过3相电流的模数转换来检测传输线中的故障,当电力系统中某个部分的电流由于故障或大过载而超过预设值时,继电器将通过向断路器发送跳闸信号来隔离该部分。基于Arduino的继电器设计和开发的主要特点是其经济、紧凑、可靠、灵活以及优于传统继电器的性能。
