Project Description

---

RSEB is an Indian state utility in Rajasthan situated in northwestern part of India.

This is a 132/33kV substation, the project is to provide complete substation automation system and RTU.

It includes communication with protection relay, energy meters using Gateway and SCADA software.The local SCADA is used for monitoring and control operation of the switch gear equipment.

The project involves relays communicating in IEC61850, energy meters communicating in Modbus. The Gateway is sending the data to remote center on IEC60870-5-104 protocol.

IEC61850 communication of Siemens BCU's in 132 kv and 33 KV bays.

The local SCADA shows online status of the substation by means of SLD screen shown in the iControl SCADA. There are also transformer wise screens, feeder wise screens, metering information screen, voltage wise screen and architecture screen shown in the SCADA.These screen displays the information of the switch gear equipment and metering details.

Silent features of this project

---

All the automation related devices like relays, SCADA servers, Gateway are time Synchronised with the GPS clock using SNTP protocol.

This project implements a fully automated and redundant SCADA-based communication system designed for monitoring and controlling a solar power integrated substation.

The system uses dual SCADA servers and a disaster recovery PC to ensure high availability, real-time data collection, and seamless switchover capability during failures.

Ethernet-based communication architecture with RS485 to TCP/IP converters enables efficient and reliable data transfer between field devices and the control system.

Gateways and RTUs are deployed to interface with relays, meters, and annunciators, providing accurate digital and analog data acquisition from the field.

Advanced protection systems are integrated, including relays for feeders, transformers, incomers, and auxiliary transformers, supported by Secure Multifunction Meters and annunciators for fault monitoring.

A Panel Ethernet Switch (PES) functions as the central communication hub, routing field device data to Ethernet switches and SCADA servers for centralized control and monitoring.

The system ensures continuous availability of operational and protection data, supporting quick fault detection, preventive action, and efficient power management.

By combining protection relays, automation devices, and redundant SCADA servers, the project delivers a reliable, secure, and scalable communication network for solar power distribution.
