Smart Grid

Smart grid – technology challenges in communications

The smart grid infrastructure has entered a stage of strong and rapid growth. With power grids distributed across vast urban and rural areas, it is necessary to ensure effective communication, that is efficient transmission of data from all network points to central command and control (C&C) systems. Metering systems and C&C systems generate large amounts of data which must be transferred effectively to the central system that manages the infrastructure.

Data from these systems is collected at medium-voltage (MV) and low-voltage (LV) transformer substations using metering, control and security devices. By consolidating these devices at a single location, it is possible to establish a central collection point for all the sensitive data they deliver. The next step is to transfer this data to the central system in a secure, effective and reliable manner. All these requirements can be met by consolidating the transmission functionality in one device.

The communications hardware that transmits data from substations should meet specific requirements, such as:

  • High bandwidth to transfer large amounts of data
  • Stable transmission to ensure constant, uninterrupted access
  • Resistance to harsh environmental conditions, such as operating temperatures ranging from -30 to +65°C
  • High level of data security with built-in encryption, certificate management and encryption key management mechanisms
