Reliable telecommunications networks

Digital high-voltage station

In the past, grid control was the sole application in classic high-voltage substations, and a legacy communication infrastructure (serial and analog interfaces) has generally been used. This configuration specified narrow-band bitrates only.

The massive changes within the energy generation structure, with unpredictable infeed of renewables as well as the deregulation of the energy markets, now place high demands on the communication solutions of transmission utilities. In order to guarantee grid stability as well as to optimize the investment (CAPEX) and the maintenance strategy, the new digital high-voltage substations generate a significant amount of data. These new applications and devices require a broadband communication infrastructure such as IP and Ethernet inside (LAN) and outside (WAN) of the substation to meet these new demands. And, last but not least, cyber security is an integral part of the communication solution.

Fiber optics

Fiber optics are the best transmission medium for medium- and low-voltage applications because they are robust and not susceptible to electromagnetic disturbances or capacity constraints.

Powerline carrier solutions

Standards-based powerline carrier solutions use the utility-owned infrastructure in the distribution network and are especially useful for connecting elements in grids where no other reliable communication channel is available.

Enterprise WiMAX / LTE

The main application area for private WiMAX / LTE systems is backhauling ring main units (RMU), data concentrators, or distributed energy resources (DER). Enterprise WiMAX / LTE networks can be scaled from small to large, which makes it suitable for privately owned network, even on a regional or local level.

Wireless mesh

Wireless mesh networks are composed of cooperating radio nodes that are organized in a mesh topology. Thanks to their mesh properties, along with self-setup and self-healing mechanisms, mesh networks inherently offer ease of operation and redundancy for fixed applications.

UHF evolution

UHF evolution is ideally suited for applications with moderate bandwidth requirements (e.g., monitoring or automation via IEC 60870-5-104). Due to the deployment of licensed spectrum and the flexibility of private network design, it is also appropriate for mission-critical applications.

Substation gateway SGW1050

Within a PLC-based advanced metering infrastructure (AMI), the substation gateway SGW1050 aggregates and transports data from the smart meters to the head end system (HES) and onward to the meter data management system (MDMS). Typically located in the distribution substation / ring main unit, SGW1050 communicates with a series of smart meters via G3-PLC over the low-voltage power line. Backhaul communication toward HES can be realized with Ethernet or cellular radio.
