Why do we need grid stabilization?

Since power is produced on demand, it's critical to ensure that the power system frequency and voltage remains within nominal ranges. Maintaining this balance is necessary to keep the power grid stable and efficient.

What are flexible AC transmission systems (FACTS) and its application?

FACTS are power electronic based devices used to improve the controllability and increase the power transfer capability of AC transmission systems by absorbing and providing of reactive power.

What are the benefits of FACTS?

FACTS can provide high dynamic reactive power to respond to voltage fluctuations caused by load changes or faults in the grid.

What are the main types of FACTS devices?

The main types of flexible AC transmission systems (FACTS) devices include STATCOM (SVC PLUS®) , E-STATCOM (SVC PLUS® FS) , synchronous condenser , fixed series capacitor (FSC) , and mechanically switched capacitors (MSC and MSCDN) . These devices are integral to enhancing grid stability and efficiency.

How is Siemens Energy advancing FACTS technology?

Siemens Energy advances FACTS technology by constantly optimizing existing solutions and developing new features. Our commitment to innovation ensures that FACTS devices continue to meet evolving grid demands, enhancing performance and reliability in modern power systems.

Why do grids need power factor correction?

Without power factor correction the power lines and other equipment would be utilized with reactive power which limits utilization with active power and will not operate at optimal condition.

What is grid-forming?

Grid-forming FACTS devices can operate on very weak grids, while grid-following devices require a more stable grid. Grid-forming devices use their built-in active power source to respond inherent to grid events.

Which additional features can be provided by FACTS?

Main additional features are: active harmonic filtering up to four different harmonics simultaneously load balancing (negative phase sequence control) POD (power oscillation damping)
