What is SCADA ?

SCADA stands for Supervisory Control and Data Acquisition.

The function is for an operator in the transmission of electricity, called the dispatcher, able to perform and take advantage of the following things:

- Telemetering (TM)

Dispatchers use TM to the needs of monitoring meters, both in MW of real power, reactive power in MVAr, voltage in kV, and currents in A. Thus the dispatcher can monitor the meters of the whole network just by sitting in place, of course with the help of other supporting equipment such as phones.

- Telesinyal (TS)

Dispatchers can use TS to get an indication of all alarms and conditions of certain equipment that could be opened (open) and closed (close)

Telecontrol Scada

- Telecontrol (TC)

Dispatchers can conduct remote control, simply by pressing a button, to open or close the electrical power system equipment For the purposes aforesaid, a dispatcher will be assisted by an integrated SCADA system which is in the room

special, and called the Control Center. The room is joined with a special room to put the computers called the Master Station.

SCADA-operated in the control center includes a variety of applications yaitusebagai follows:

- Data acquisition

- Supervisory Control

- Monitoring data, event processing (events) and alarms

- Calculate data

- Tagging (tagging)

- Recording data

- Reporting

Besides the need for a control center, on the other side should put up the infrastructure and other supporting equipment, namely telecommunications, Remote Terminal Unit (RTU), transducer, and so forth. Telecommunications used as a data and voice communications between the control center

the site (location). RTU is used as a terminal unit for control, data acquisition, and the supervision of a substation, and then sends that data to the control center in question.
