To ensure a comprehensive overview, it is crucial to record energy data at all levels. This requires a differentiated approach, as intelligent energy distribution grids require more powerful measurement technology than conventional systems.
Comprehensive measurement
Comprehensive recording of energy data at all levels is crucial for the success of the energy transition and for overcoming its many challenges. This requires comprehensive monitoring of the grids, ranging from substations to decentralised distributors or generators.
The requirements for measurement technology vary depending on the needs. Intelligent energy distribution grids, for example, require more advanced measurement technology compared to conventional systems. The specific measurement environment also plays a role, as the measurement technology in a substation has to fulfil different requirements and tasks than in a local grid station.
Janitza/Optec offers customised, technically high-quality and scalable solutions for these requirements.
Comprehensive recording of energy data at all levels brings a wide range of benefits, including
- Faster fault analysis
- Solid basis for network planning
- Provision of data for automation and control systems
- Increased availability by reducing downtimes
- Reduction of transmission, distribution and non-technical losses
- Management of decentralised energy generation (e.g. photovoltaics, hydropower plants)
- Voltage regulation in local grid stations
- Fulfilment of regulatory and tariff requirements (documentation obligation)
- Monitoring the power quality (e.g. in accordance with EN 50160)
- Controlled integration of new technologies (e.g. electric vehicles, energy storage systems)
Measuring in the substation
High-quality class A power quality analysers such as the UMG 512-PRO are required for measurements at transfer points in the substation. Typical applications include feed-ins, transfer points from the higher-level supplier or important outgoing feeders to critical major customers. In addition to precise energy measurement, the focus at this level is on monitoring the power quality with its various parameters.
The large number of interfaces and protocols of the UMG 512-PRO ensures simple system integration (control room, SCADA, GIS). In addition to transmitting operating states and load flows to the control centre, a separate parallel system is usually set up for power quality analysis and grid planning.
