How does SCADA work?
The SCADA system requires data to be collected from substation equipment and its transmission over a telecommunications circuit to computers in Wilton and Leopardstown Distribution Control Centres (DCC). The computers analyse and translate the data received into an on-screen visual representation of the substations, enabling the Control Room Operators in the Distribution Control Centres to interpret and make operational decisions. This may require direct operation of equipment or the dispatch of Network Technicians to investigate the fault and carry out repairs. The two Distribution Control Centres provide 24/7 monitoring, operation and control of the 110kV and 38kV networks assigned to them. Leopardstown DCC controls and operates substations north of a line from Dublin to Castlebar. Wilton DCC is responsible for the balance of the networks south of this line. Apart from communications with Supervisors and Network Technicians involved in the control and operation of the medium voltage
