Ensuring distribution network quality in smart grids

Protecting network equipment

INSYS Smart Devices of the MLR series have proven their performance on a pilot project of REWAG Regensburger Energie- und Wasserversorgung AG & Co. KG, Ostbayerische Hochschule Regensburg OTH and Maschinenfabrik Reinhausen.

Added value

  • Identify hotspots immediately

  • Managing distributed supplies

  • Monitoring sensitive processes

  • Ensuring distribution network quality in smart grids (DIN EN 50160 and 61000)

Initial situation

Renewable energies are already forming the basis of a sustainable energy supply. The integration of the local and volatile renewable energy producers is a challenge.

The medium-high and low voltage systems are being converted to smart grids to maintain network quality and supply reliability. Additional measuring and data technology always provides latest network operation data.

The availability of data about network damping and hotspots is critical for the business:
– Distribution network operators use it to control their networks.
– Companies with sensitive processes use it to monitor special quality agreements with their power suppliers.

Objective
  • Integrating renewable energy producers
  • Ensuring distribution network quality in smart grids
  • Equip electricity distribution with modern data technology
  • Protecting equipment
Solution

Basic measures for increasing the capacity of existing networks and managing the network reactions when connecting renewable energy sources are for example:

  • Voltage control at the local distribution system transformer

  • Reactive power control at the PV converter

  • Generation management by power limitation or shutdown

  • Protection of network equipment like transformers, aerial lines and cables

INSYS Smart Devices of the MLR series have proven their performance on a pilot project of REWAG Regensburger Energie- und Wasserversorgung AG & Co. KG, Ostbayerische Hochschule Regensburg OTH and Maschinenfabrik Reinhausen.

16 significant values have been read out every 10 seconds from more than 70 local distribution system transformers by an app in the router, provided with a standard time-synchronous date/time stamp, stored and sent to the OTH as an XML file – more than eight billion data records have been read, processed and transmitted reliably.

Summary

Field-proven routers like the programmable INSYS Smart Devices (MRX, MoRoS, EBW, MLR) with INSYS SmartBox or Sandbox and the innovative Connectivity Service of INSYS icom contribute significantly to smart grids.
