Flexible AC Transmission Systems
Flexible AC Transmission Systems (FACTS) increase the reliability of AC grids. They improve power quality and transmission efficiency from generation through transmission down to the private and industrial consumers: Better utilization of the network, increased availability and reliability as well as improved network stability are achieved along with higher supply quality.
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.
