Real-time monitoring system for mains operation

A provider of solutions for the energy market, Phoenix Contact ─ in collaboration with JEAN MÜLLER ─ has developed a scalable monitoring system for mains operation that provides measured operating values in real time for grid optimization or grid management purposes.

As energy will increasingly be supplied to the grid by volatile regenerative power stations – particularly at the lower voltage levels of the distribution system – intelligent solutions are needed in order to ensure that the energy supply remains highly available. The rise in e-mobility also plays a role here.

The system is designed such that it can be installed in secondary distribution network stations, cable distributors or customer systems by mains operators with minimal configuration and installation outlay. If needed, the application can be extended to include a central asset management system that calculates the current load flow based on quantified measured values. In addition to transferring measurement data from up to 14 strip type switch disconnectors to central control systems using IEC standard protocols such as IEC 60870-5-104, these systems can also communicate directly with IoT ecosystems via interoperable data models.

The NH strip type switch disconnector from JEAN MÜLLER ─ which integrates the new PLPlano measurement technology ─ records currents, voltages and relevant grid parameters. This data is provided to the higher-level controller via the Modbus RTU. The measuring technology employed is very compact, and the connectors can still be used in all common cable distribution cabinets. The communication and power supply systems are quickly and easily connected by USB-C cable. The electronics can also be replaced during active operation to ensure that consumers have power at all times.

The Energy Control Interface (ECI) from Phoenix Contact records these values with a serial protocol, processes them and relays them to higher-level management systems by way of flexible communication media. PLCnext technology from Phoenix Contact lays the groundwork for this. In addition to implementing your own high-level, language-oriented applications – such as controller programming via Matlab Simulink – you can also create complete data objects to digitally describe a substation. This will enable direct communication between two substations in the future.
