We are the lead in a consortium with EDMI of Singapore and Totaltel Pty of Bangladesh, and together we will supply and install the meters, along with connection to the SCADA system that Abbey Systems supplied to Chittagong in 2011. It’s a sophisticated metering system, which has several unique features; enabling the BPDB to view metering data remotely in real time, as well helping to locate illegal power connections, which are a considerable issue in a country where a significant amount of power and income is currently lost through these connections.
Connecting meters sites to the SCADA system will allow comparisons to be made between how much energy goes out on each feeder and how much energy is actually used by customers - helping to identify areas where there are illegal connections. Since maintaining infrastructure in Bangladesh can have its problems, each meter communicates with control room through two paths: GPRS (a type of mobile data service) and WiFi. The WiFi network is owned and operated by BPDB and the GPRS is owned and operated by a local provider. This diversity of paths ensures that at least one way of communicating with the control room is available at all times. At the control room, meters are grouped according to the feeders that they are connected to and the energy and power values are compared with the energy and power flowing out through the feeder. Voltages along the feeder are also monitored to determine line loss and loading characteristics. We are approximately 20% of the way through delivery of the project and will keep you updated as it progresses.
