Abstract

Abstract: According to the problem of low intelligence and poor inter-device operability of the traditional box-type substation’s control system, a design scheme of intelligent monitoring device is proposed for box-type substations according to the functional requirements of the box-type substations. The hardware platform is designed based on the processors S3C2440A and STM32F4. The information interaction is realized via LAN communication. The function is analyzed and the information model is established according to the IEC 61850 standard protocol. The experimental results show that the precision of voltage, current and active power of the device can reach level 0.3, and the reactive power can reach level 1. The operation of the box-type substation can be supervised in real-time, and such functions can be realized as the communication inter-operation between devices, the automatic control, fault alarming and auto-reclosing.

Key words: box-type substation, intelligent monitoring device, FIR filter, IEC 61850
