Flexible AC Transmission Systems
The growing number of small, decentralized power plants such as solar, wind, and biogas plants is making it much more difficult for grid operators to ensure reliable and stable grid operation. Flexible AC Transmission Systems (FACTS) are the perfect solution for increasing the reliability of AC grids, improving power quality, and boosting transmission efficiency. Siemens Gas and Power supports customers around the world with innovative FACTS to help them master the challenges of energy transitions.
Stable equilibrium: Power electronics bridges gap in energy transition
Whether it’s in the icy North or the extremely humid Amazon rainforests, static synchronous compensators (STATCOMs) are high dynamically ensuring stability and flexibility of power grids around the world.

Grid stability and power quality made to measureWhile every power grid has specific challenges in terms of power quality, reactive power compensation, and grid stability, our FACTS systems offer customized solutions to these challenges from a single source for utility and industrial applications.
Modular FACTS devices to suit all demands
Flexible AC transmission systems (FACTS) are a family of power transmission solutions that contribute to enhanced grid stability and power quality. Its specialized devices offer either parallel or series compensation.
While series compensation is primarily used to increase the power transfer capability on transmission lines, Siemens devices for parallel compensation influence the network voltage at their point of common coupling by actively injecting or absorbing reactive power. Parallel-connected synchronous condensers stabilize the network by providing short circuit power and inertia. With these solutions installed in the system, unacceptably high voltage fluctuations and power failures can be prevented, network assets can be optimally utilized, and load-induced disturbances can be mitigated.
