Flexible AC Transmission Systems
The increasing number of small, decentralized power plants like solar, wind or biogas plants making it much more difficult for grid operators to ensure reliable and stable grid operation. Flexible AC Transmission Systems (FACTS) are the perfect solution to raise the reliability of AC grids, improve power quality and boost transmission efficiency. Siemens Gas and Power supports customers all over the word with innovative FACTS in mastering the challenges of energy transitions.
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.
