The significant expansion of volatile photovoltaic systems and wind turbine generators as part of the power supply infrastructure poses new challenges in the form of unplanned capacity bottlenecks and voltage stability problems. However, the expansion of intelligent stations and the modernization of existing grids often takes a long time. The monitoring of grids is already ensured today with the help of data acquisition for voltage and power values. In addition, control measures also ensure the safe operation of an intelligent secondary substation in the future. Phoenix Contact solutions can be used to automate and digitalize substations and ensure consistent communication in the grid operator’s power grid.
Solution
Modular automation system for intelligent secondary substations
Phoenix Contact offers a flexible, robust, and highly secure solution for the digitalization of secondary substations in the medium- and low-voltage grid. By using connection and network technology, it is possible to combine measurement technology, remote control technology, and the industrial PLCnext software in one platform. In this way, all important components are linked to form a controllable, highly reliable system with a focus on cybersecurity. An industrial device and patch management system is available for the safe commissioning, simple maintenance, and updating of remote control technology and automation systems.
Your advantages
in an intelligent secondary substation
All information about your secondary substation at a glance: active and reactive power, current, voltage, error messages, and warnings
Fast fault localization and selective remote troubleshooting
Short response times in the event of a fault and disruptions are minimized
Fast load disconnection and switching through to sectioning point relocation
Determination of the short-circuit and ground fault direction to detect and shut down grid faults near the point of origin
Remote control cabinet for the automation of digital stations
Power reliability
Reliable supply solutions consisting of power supply, surge protection, and device protection are essential for the operation of all electrical or electronic devices in an intelligent secondary substation. To ensure consistent communication, even during mains failure, the power supply is set up in combination with a battery as a backup.
Whether in a control cabinet or in the field – the energy industry places very high demands on the connection technology in intelligent secondary substations. It must be as safe and secure as it is durable, and it must also be easy to operate. Connection technologies from Phoenix Contact meet these demands – from screw connection through insulation displacement contact to Push-in connection.
The term energy automation covers solutions for the efficient operation of power grids. The modular control and remote control technology from Phoenix Contact meets the high demands for availability, EMC, and IT security in intelligent secondary substations. For example, the solution is used to acquire information and transmit the latest current and system data from the low-voltage side to a network control center or a central database.
As part of the critical infrastructure, the energy sector requires a high-performance and secure communication network for the reliable operation of intelligent secondary substations. High demands are placed on availability, reliability, and security when monitoring stations in distribution grids. Phoenix Contact provides the necessary products, such as those with Modbus connection, to achieve this goal.
Monitoring parameters is a fundamental requirement for the efficient expansion and reliable operation of smart grids. Phoenix Contact offers everything you need for this from components to coordinated complete systems.

Grid protection concept for the GRÄPER Group
Due to the increased production capacity of an industrial company, a new grid connection is required in the grid operator’s 10 kV grid. For the amount of energy required, the customer needs a correspondingly large transformer and a grid protection concept. Phoenix Contact is therefore supplying the GRÄPER Group with the appropriate remote control cabinet and the smartRTU modular remote terminal solution.
