“…PLC as a data transmission technology in modern smart grids and also for LoM protection has been studied extensively; see for instance [1], [6], [7]. In the proposed concept [5], the signal transmitter is placed on the MV grid.…”

“…System Architecture In Europe, a typical AC power distribution grid includes a primary substation, which is the system interface between the transmission and distribution grids. The primary substation supplies an MV grid, which usually has several branches [7]. Each MV branch is terminated to 20/0.4 kV distribution transformers, whose secondary side, the customers, and DGs are connected by LV grids.…”

Loss-of-mains (LoM) protection is crucial in modern smart grids (SGs), where the number of distributed generation (DG) units has increased making the grids more complex. An LoM situation means that the DG unit(s) is/are still supplying the grid while the connection to the supplying electric power distribution grid is off. This can cause fatal injuries to humans and damages to the equipment. A power line communication (PLC) based LoM concept is introduced, where continuous signaling is used as an indication for the LoM protection from the primary substation through the MV grid, the MV/LV transformers, and each low-voltage (LV) grid to the customers. However, the MV/LV transformers constitute a barrier for the PLC. Thus, in this paper, the channel characteristics and modeling of the MV/LV transformer as a function of frequency in the frequency band from 100 Hz to 1 MHz is analyzed. A model for the transformer is compiled and verified by input impedance measurements.

“…SWER network is a single-wire distribution system in which all equipment is grounded to earth and the load current returns through earth [71]. The SWER networks can be more than 2000 km long and include many branches [72]. They are connected with the three phase networks through an isolation transformer which also serves to isolate the earth current of the SWER networks (see Fig.…”

“…Apart from electromagnetic compatibility (EMC) issues in PLC generally [20,21], other major arguments against BPLC have been that 2-30 MHz cannot traverse an medium voltage/low voltage (MV/LV) step-down transformer without external bypass coupling circuit and that it suffers from high attenuation with distance [6]. Even with a bypass coupler, theoretical studies [22] and field trials results have shown that the three-phase distribution transformer exhibits asymmetric transfer function between LV-MV and MV-LV paths [23]. A common inference from both studies is that such an asymmetric behaviour could affect data rate regardless of whether NPLC or BPLC is employed.…”

Broadband PLC for Clustered Advanced Metering Infrastructure (AMI) Architecture

Advanced metering infrastructure (AMI) subsystems monitor and control energy distribution through exchange of information between smart meters and utility networks. A key challenge is how to select a cost-effective communication system without compromising the performance of the applications. Current communication technologies were developed for conventional data networks with different requirements. It is therefore necessary to investigate how much of existing communication technologies can be retrofitted into the new energy infrastructure to cost-effectively deliver acceptable level of service. This paper investigates broadband power line communications (BPLC) as a backhaul solution in AMI. By applying the disparate traffic characteristics of selected AMI applications, the network performance is evaluated. This study also examines the communication network response to changes in application configurations in terms of packet sizes. In each case, the network is stress-tested and performance is assessed against acceptable thresholds documented in the literature. Results show that, like every other communication technology, BPLC has certain limitations; however, with some modifications in the network topology, it indeed can fulfill most AMI traffic requirements for flexible and time-bounded applications. These opportunities, if tapped, can significantly improve fiscal and operational efficiencies in AMI services. Simulation results also reveal that BPLC as a backhaul can support flat and clustered AMI structures with cluster size ranging from 1 to 150 smart meters.
