August 7, 2019 - ABB is delivering excitation solutions designed to ensure early compliance with European regulations, connect grid networks and support stable operations.

ABB’s UNITROL 1000 series is an excitation product that is fully compliant with the European grid code pioneered in Germany.  Compliance of ABB UNITROL 1000 devices to the German grid code (VDE-AR-N 4110 and VDE-AR-N 4120) has been validated by the TÜV NORD certification body.

The European grid codes are a set of rules that harmonize, integrate and improve efficiencies across the electricity market. They are a key system put in place to help the EU achieve its energy objectives and reduce greenhouse gas emissions by increasing renewable energy share and energy savings. The regulations strengthen rules for connecting plants to grid networks, in response to an increasing number of distributed renewable assets, such as wind farms and photovoltaic plants, overloaded grids and integrated E-mobility.

Excitation systems are a key component in many power generating units used by plant owners and operators to achieve reliability with operations, stability and transient response of their assets, as per grid requirements.

Compliance to the German grid code and to the latest ENTSO-E regulations can be achieved also by 20,000+ UNITROL 1000 customers around the world, by means of a new generation of dedicated software with supporting functions which, once installed, support existing assets complying with the new standards.

For ABB customers, full compliance with the latest European grid code requirements will enable holding a certification that remains valid – even if there are updates to excitation system firmware. Customers will also receive access to a simulation model available to integrate in generator control models. Such an integration may accelerate full generator set certification.

ABB has enhanced detailed grid code compliance studies – including modeling of power plant major components – to help operators provide necessary simulations reports and performance evaluations for national Transmission System Operators (TSOs). This, in turn, supports allowances to connect to national grids.
