GSM/GPRS Wireless Sub Station Automation:
GSM/GPRS wireless data loggers RTUs are used for electric sub station automation. SCADA application is used to monitor and control the HT transformer from a central control room. With the help of GSM/GPRS wireless data loggers RTUs, we can monitor oil temperature, winding temperature, level of oil in the tank, bucholtz relay status in the central control room through SCADA interface.. The SCADA interface can display data of a number of remotely installed HT transformers at scattred sub stations. The wireless monitoring and control data loggers RTUs can also check the power failure, overloading, unbalance load sharing, parallel operation of HT transformers, OLTC operation. At the central control room, the SCADA interface can store the data for report generation, alert setting, automatic switching operation from remote. We can monitor the status of VCB/OCB on our mobile phone. More...
Wireless SubStation Automation - GSM/GPRS RTUs/PLCs:
Softbitonline manufactures wireless RTUs for wireless substation automation. The substation equipments are connected with the GSM/GPRS PLC/RTU for automatic operation. We can monitor the substation from a central control room PC. The remote substation can be switched off automatically or from the control room PC. A specially developed SCADA software is used to put the electric sub station in full automatic mode. A sub station has equipments like HT transformer, OCB/VCP, electrical control panels, battery charger, relays. All these equipments are required to smoothly run a sub station. More...
HT sub stations are installed for supplying electricity to residential, commercial and industrial consumers. Size of an electric sub station depends upon the load requiremnts of the area. Depending upon the requirements, a sub station can be installed one in one colony. More than one sub stations can also be installed nearyby if the load requirement is high. Pole mount sub stations are generally installed at the main gate s of factories. These pole mount sub stations are easy to maintain as the fault, if occures can easily be accessed and rectified. So pole mount electric sub stations are more popular in industrial areas. More...

Wireless Sub Station Automation - Why?
Electric sub station automation is required for keeping a continuous check on the working and performance of the sub station. Sub station automation helps to operate the ht transformer and associated switchgears and equipments in automatic way. Sub station automation can be localized where the data monitoring and data recording is done on a local PC. But sub station automation can also be done for remote monitoring and control. In this case we install wireless GSM/GPRS RTUs at the sub station for automation. Sub station automation is must for unmanned sub stations. Wireless sub station automation help us in monitoring all the electrical parameters from central control room. We can generate daily reports from remote server which is being populated with regualar data from sub station where sub station automation is implemented.
Remote Substation automation requires wireless PLCs/RTUs with I/Os and D/Os to monitor the data of various equipments installed at sub station. Sub station automation can be local or PC based and otherwise wireless, GSM/GPRS based. Which method is to be applied for sub station automation depands upon the site requirements and site conditions.
RTU For Wireless SubStation Automation:
Softbitonline has developed a special GSM/GPRS enabled PLC/RTU for wireless substation automation. Our model SB-Smart(4Ch) has 4 analog inputs for connecting winding temperature sensor, oil temperature sensor, body temperature sensor, 4 x digital inputs for monitoring the status of buchlotz relay to know gas explosion, temperature rise and low oil level and status of OCB/VCB. Then this model have 4 aux. relays for switching and tripping the transformer in case of emergency in auto mode or from remote control room through SCADA system. Cooling fans can also be operated automatically through these relays based on temperature rise of trnaformer becasue of over loading. All the parameters such as sensor data, electrical data, status is shown in the central control room live in real time.
Remote Substation Automation - A Challenge:
Substation automation and remote operation of an unmanned substation requires a large amount of crucial data from field devices such as reclosers, protection relays such as buchlotz, earth fault, over current etc., and disconnectors. These data are real-time measured values, alarms and events, disturbance records, fault locations, and so on. This must all be communicated to the control room in a secure and reliable manner. Softbitonline is well equipped to undertake such data transmission jobs with its GSM/GPRS enabled RTUs. We have also done remote monitoring and operation of substations using fibre optic. This helps in fast data flow between the transformer and remote control room.
