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.
All the automation related devices like relays, SCADA servers, Gateway are time Synchronised with the GPS clock using SNTP protocol.
The project involves the design and implementation of a system communication network for an electrical power distribution system, integrating SCADA (Supervisory Control and Data Acquisition) with various metering and relay components.
The Gateways 1 and 2 have been configured in redundancy to receive data from 61850 relays from both 132 kv and 33 kv bays.
SCADA SERVER-1 was configured to handle data collection and control for the 132kV feeder, while SCADA SERVER-2 was set up to manage data for the 33kV feeders. A dedicated DR PC was deployed for data recording and analysis.
Ethernet Switch-1 was installed to connect the SCADA servers to the TVM meter communication, and Ethernet Switch-2 was used to manage the communication between the SCADA servers and the DR PC.
TVM meter communication was established for the 132kV feeder, transformers T1 and T2 at both 132kV and 33kV sides, and for multiple 33kV feeders (04 to 08). This setup ensured reliable data acquisition from all major feeders and transformers.
Relay and metering devices were integrated, including BCPU 7SJ66 relays for the 132/33kV transformers, differential relays for protection, distance relays for fault location, high-voltage reference signals, and cable differential protection relays.
A server status mechanism was implemented to display the status of the current and peer servers, along with switchover readiness, ensuring high system availability and reliability.
Through this implementation, the communication structure was streamlined to enable efficient monitoring, control, and protection of the power distribution network.
Log and daily consumption report generated and verified with values.
