SCADA and Substation Automation Systems for the Port of Durban Power Supply Upgrade

The Port of Durban (PoD) is currently upgrading its existing power supply to a supply voltage of 132 kV. The design of this electrical substation system will take into consideration the modernization of the substation system that will improve flexibility and improved efficiency. Modern power systems substation are equipped with Intelligent Electronic Devices (IEDs). The IEDs are designed to comply with IEC 61850 standard communications protocols with interoperability features for substation protection, control and coordination. Substation Automation Systems (SAS) provides facilities for monitoring and controlling all the equipment in the substation locally and remotely. The Supervisory Control And Data Acquisition (SCADA) system will be developed to provide users/operators with Human Machine Interface (HMI) or graphical representation of the electrical substation that will be used for controlling, monitoring and protection of devices in real time and this will help maximize availability, efficiency, reliability, safety and data integration.
