Relay protection device DSP board

In order to ensure electrical railway's safe and stable operation, a kind of microcomputer feeder protection device based on a double "ARM+DSP" CPU framework is designed. The hardware design can not only Improve protection performance, but also realize IEC61850 communication. DSP series devices are 8A power relays that are nearly as small as signal relays. The broad line-up consists of 54 types, including single side stable, 1 coil latching and 2 coil latching operating functions for all contact arrangements (1NO, 1NO 1NC, 2NO). Direct driving by transistors and chips. With the development of power system, low-voltage direct current (LVDC) distribution system has shown advantages in absorbing new energy, improving energy utilization and power quality, and compatibility with increasing DC load and frequency converter [1,2].

A comprehensive relay library based on manufacturer-specific protection devices is available and can be used in steady-state and for dynamic simulation. The protection device models are highly detailed and completely aligned with StationWare, allowing settings exchange with real protection devices. Note) Reverse polarity type ( AGP9**** ) are manufactured by lot upon receipt of order. For the sockets, please refer to the " PC board sockets ".
