Application for Energy Suppliers
The energy sector is changing rapidly: a growing share of renewables, increasingly dynamic loads, and the ever-present demand for uninterrupted supply. To cope with this, utilities need full transparency of energy flows in their networks. Only with this transparency can grid stability be secured, overloads avoided, and losses minimized.
Determination of network status according to Section 14a of the German Law on Energy Management
The Challenge
Mandatory grid condition assessments according to Section §14a EnWG form the basis for grid-oriented control. Utilities must document grid states and issue control commands within five minutes. In case of grid-oriented control, operators must prove critical situations with feeder-level measurements to justify interventions.
This requires not only equipping new substations and distribution systems with measurement technology but also retrofitting existing ones. Older systems often lack the necessary data connections, and space is limited.
Solution
The UMG 800 delivers the required transparency for implementing the requirements of Section 14a. With expansion modules and measurement groups, one device can monitor up to 32 outputs. Its slim design and compact modules make it suitable for both new and existing installations.
Numerous communication interfaces, whitelisting, custom Modbus address lists, and other features simplify integration and enable real-time data transmission.
Evaluation
With the Remote Display RD 96, operators can read and analyze UMG 800 data locally. Configurations can be performed on the display, which can be installed permanently or used as a mobile service tool. Connection is via USB. Remote maintenance and analysis are also possible via the integrated web server.
System Integration
With its 2 sub-units in size and compact 800-CT8-LP modules, the UMG 800 integrates easily into substations. Interfaces such as OPC UA and Modbus TCP/IP enable straightforward integration into higher-level systems. Security features like Modbus Whitelisting protect communication. An internal 4 GB memory buffers data if connections are interrupted.
Network Stabilization with the UMG 800
The Challenge
A regional utility wanted to improve energy efficiency and optimize consumption in its grid. Despite modern technology, unexpected load peaks and inefficient consumption patterns drove up costs and caused instability.
Solution
The energy supplier deployed the UMG 800 to monitor gridded and sliding average values, providing a precise long-term view of energy consumption and grid load. Critical 200 ms min/max values were especially useful for detecting peaks early and preventing issues. This allowed the company to take targeted measures, avoid outages, and optimize energy use.
Technicians could integrate the UMG 800 seamlessly with OPC UA and Modbus TCP, enabling constant monitoring and informed decisions for grid optimization. Continuous monitoring of averages revealed inefficiencies and supported sustainable energy-saving measures.
Network Stabilization
Gridded and sliding average values reveal consumption trends. Critical 200 ms values help detect peaks early so operators can respond promptly. The UMG 800 also provides 1-minute averages for current and power, supporting regulatory compliance and proactive stabilization. High levels of measuring accuracy and realtime data enable rapid responses in the event of faults.
Further Highlights for Energy Suppliers
Communication
The UMG 800 can be easily integrated into third-party systems via OPC UA, Modbus TCP, and the web server. Operators can configure Modbus address lists for flexible data mapping. The Remote Display RD 96 allows local data access and analysis, configurations and fault analyses can be readily carried out on site. Integrated comparators reduce data traffic and associated costs by sending alerts only on threshold violations. A 4 GB memory ensures data is secure even if communication is interrupted.
Cost-effective
Thanks to the virtual measurement groups, you can reduce hardware costs and optimally use measurement channels. Create and combine measurement values for 3- and 4-phase applications efficiently and in virtual terms – without additional hardware. Use of virtual parameters means you can reduce the number of physical devices that are required.
