Primary Substation Communication

Primary substation communication to control centers

Electricity companies are constantly working to improve their quality of service, which requires a redundant and resilient data communications network. However, the situation today is that many primary substations are connected to the control centres via outdated leased lines and analogue modems with insufficient bandwidth and reliability. Upgrading the data communications networks could mean installing new fibre optic cables for up to 1,000 individual substations spread across large geographical areas which in most cases would not be economically feasible. Additionally, the scale of the network requires installation and configuration to be simple, and network maintenance to be easy and efficient, while cybersecurity must be effective, as security breaches can cause downtime in entire cities or nations.
