SVC PLUS® (STATCOM)

Static var compensators (SVC Plus) and static synchronous compensators (STATCOMs) solutions for utilities.

As power grids transition from conventional synchronous generation to renewable energy sources, they face significant challenges in maintaining stability and efficiency. The integration of variable energy sources can lead to voltage fluctuations and reduced grid reliability. STATCOM solutions for utilities provide the ideal solution, offering dynamic reactive power compensation and voltage regulation to stabilize the grid and support the seamless integration of renewables. These solutions are integral to flexible AC transmission systems (FACTS), enhancing the overall performance of power transmission networks.

Siemens Energy SVC PLUS® stands at the forefront of grid enhancement technology, delivering innovative and universally applicable solutions for reactive power compensation. Our advanced STATCOM, equipped with modular multilevel converter (MMC) technology, offers superior benefits compared to conventional solutions. While traditional SVC installations provide dynamic voltage regulation, the modular multilevel system of SVC PLUS® is even faster and more efficient. Additionally, Siemens Energy offers mobile SVC PLUS® solutions to support short-term grid changes and rapid restoration after severe incidents, ensuring robust and reliable grid performance. These advancements are crucial for modern power transmission, reinforcing our commitment to driving the energy transition.

SVC PLUS® represents a significant advancement in static var compensation, combining the benefits of static synchronous compensation (STATCOM) with cutting-edge modular multilevel converter (MMC) technology. This innovative approach optimizes the number of components required, enhancing both performance and efficiency in power transmission systems.

Despite its outstanding capabilities, SVC PLUS® requires relatively few system components, simplifying the design, planning, and engineering of new projects. The system utilizes proven and robust components, including industrial-class insulated gate bipolar transistors (IGBT), reactors, capacitors, and, in utility applications, AC power transformers. This streamlined design not only enhances reliability but also reduces the complexity typically associated with conventional SVC systems.

Thanks to MMC technology, SVC PLUS® offers exceptional flexibility in the design and layout of converters and substations. The modularity and reduced number of system components significantly decrease commissioning time, making it an ideal choice for modern power transmission projects. This efficiency and adaptability position SVC PLUS® as a leading solution in the realm of static var compensation, supporting the evolving needs of power grids worldwide.

When comparing STATCOM and SVC (static var compensation), both technologies serve the crucial function of reactive power compensation and voltage regulation in power systems, yet they differ in their operational mechanisms and performance capabilities. STATCOM, utilizing voltage-sourced converter technology, offers faster response times and greater flexibility in managing reactive power, making it ideal for dynamic grid conditions and renewable energy integration. On the other hand, SVC employs thyristor-controlled reactors and capacitors, providing effective voltage regulation with a proven track record in stabilizing traditional power grids. While SVC systems are robust and reliable, STATCOM solutions are increasingly favored for their adaptability and efficiency in modern, complex energy landscapes, particularly where rapid adjustments to grid fluctuations are necessary.
