Monitoring of power quality e.g. according to EN 50160
Quality Class A power quality analyzers such as the UMG 512-PRO are required for carrying out measurements on the transmission points in the transformer station.
Typical applications include the infeeds, transfer points from upstream suppliers or large-scale outflows to critical customers. Power quality, with its myriad parameters, are of the utmost importance on this level alongside highly accurate energy measurement. Various interfaces and protocols on the UMG 512-PRO mean a simple system connection (control room, SCADA, GIS) is ensured. Usually an in-house parallel system is set up for PQ analysis and network planning alongside reporting of operating states and load flows to the control room.
The key to successful implementation of the energy transition and its many challenges is a comprehensive overview of the networks. To achieve this, energy data must be collected at all levels – from the transformer station to the decentralized distributor or generator.
How powerful the necessary measurement technology needs to be depends on the requirements. For example, smart energy distribution networks require more powerful measurement technology than conventional systems. The measurement level also plays a role. For example, measurement technology in a transformer station must fulfill different requirements and tasks than measurement technology in a distribution substation. Janitza offers customized, scalable solutions with high-quality technology for these applications. Energy data collection at all levels brings numerous benefits.
The central idea of extensive measurement requires the installation of "remote" measurement devices at the lowest level, such as cable distributors, house connection boxes, decentralized generation plants, or even special contract customers.
At this level, very compact and cost-effective measurement devices – such as the UMG 103-CBM – are required. Higher-quality power quality analyzers – such as the UMG 605 – are also frequently used for regenerative generation plants. The communication connection is made at the distribution substation. If no infrastructure is available, regular readouts can be made with the GridVis® Collector, for example.
Distribution substations play a key role in the expansion of the distribution network. Due to the high quantities, they are very cost-intensive.
A scalable solution is recommended here, e.g. the 20CM, which, thanks to modular expansion to up to 96 current measurement inputs, can measure several outputs simultaneously. This reduces the initial investment costs. At the same time, it is future-proof, because the measurement points can be easily expanded.
e.g. to EN 50160
For a comprehensive overview, energy data must be collected at all levels. Moreover, the fact that intelligent energy distribution networks require more powerful measurement technology than conventional systems must also be taken into account.
