Saudi Electricity Company
Due to the fact that medium voltage grids in Jeddah/KSA are subject to high network loads, a feasibility study with installation, enabling station monitoring, was carried out. The aim of this study was to enable the appropriate response to temporary or sudden network overloads. This was achieved in Jeddah by installing PPC’s 11kV medium voltage couplers in combination with special MV modems. Using the MV Power line, the grid could be monitored between a number of transformer stations.
An additional aspect of our cooperation with SEC was to examine to what extent the power grid was suitable for Smart Metering. Various households were equipped with Landys+Gyr electricity meters (type ZMD 310). The data was successfully read and displayed in real-time via RS485 interfaces. Thus, Broadband Powerline enabled remote meter reading of the electronic meters.
