CSPTCL is an Indian state utility in Chhattisgarh situated in centre-east part of India.
CSPTCL has been following the automation methodology of automatic data logging system (ADLS). In ADLS, the data from communicable protection relays and energy meters is read in the gateway(iGrid iGW). The data from the gateway is read in the local SCADA system at the substation.
The SCADA system is a stand-alone system with provision to view the protection status, alarms, events are collected from the IEC61850 relays. Modbus communication is used to communicate and collect the data from energy meters. The iGrid iGW gateway in the substation is collecting the relay and meter information. The gateway also synchronises the time from GPS (Global positioning system) system.
The local SCADA system (iGrid iControl) is installed in the substation computer.
The local SCADA shows online status of the substation by means of SLD screen shown in the iControl SCADA. There are also Voltage wise screens, individual bay screens, metering information screen and architecture screen shown in the SCADA. These screen displays the information of the switch gear equipment, protection status and metering details.
