Traditionally, electrical network protection schemes rely on hardwired connections between Intelligent Electronic Devices (IEDs). The problem with that approach is it makes it difficult to correct, modify, or update the… Read more »
In my previous posts in this series, I wrote about protection network redundancy protocols, and delved into some details about PRP and HSR. When defining network communication architecture, it’s worth… Read more »
Like PRP, the High Availability Seamless Redundancy Protocol (HSR) applies the principle of parallel operation to a ring interconnecting IEDs with two links. HSR relies on ring topology, sending data… Read more »
PRP relies on the parallel operation of two local area networks (LANs). It allows a mixture of both redundant and non-redundant equipment on the same network. These are the operating… Read more »
Historically, protection and control (P&C) schemes relied on hardwired communication: direct, point-to-point connections between Intelligent Electronic Devices (IEDs). The problem with that approach is it’s difficult to correct, modify, and… Read more »
