Winning the Grid Code Compliance challenge: a world first

Power grids throughout the world are going through a period of unprecedented change. Penetration of utility-scale renewable plants continue to increase, calling for a more robust electricity infrastructure.

The right level of stability is granted by standards and grid codes, which seek to ensure the stable and safe operation of the network by defining the main factors that must be considered when connecting any kind of power generation plant to the grid.

Europe, for example, has introduced the new ENTSO-Estandard, which requires all European countries to define new grid codes. Germany, as a front runner, has released first grid code VDE-AR-N 4110 and VDE-AR-N 4120 standards.

ABB’s UNITROL® 1000 series is the world’s first excitation product fully compliant to the new European grid code, as validated by the renowned TÜV NORD certification body according the German standards, which are – so far – the most challenging grid codes in terms of physical tests, as well as for demanding simulations models with very high accuracy for dynamic net faults.

Why choose UNITROL® 1000?

Upgrade your existing asset through a simple software

Compliance to the latest ENTSO-E regulations can be achieved by the 20,000+ UNITROL® 1000 customers around the world by means of a new generation of dedicated software with supporting function.

Making your life easier with grid code compliance studies

ABB’s detailed grid code compliance studies for power utilities have been further improved to help operators provide the necessary simulations reports and performance evaluations to their national Transmission System Operators (TSOs) and therefore get allowance for connection to their national grids.

My benefits

- An excitation system that fulfills the latest and most stringent German grid code requirements certified by TŰV Nord
- No need of re-certifying your power generating unit in case of AVR firmware update or exchange with another certified ABB device
- State-of-the-art simulation model that could be easily integrated in the generator control model and therefore accelerate the full generator set certification.
