SVC PLUS (STATCOM)

Whenever an innovative and universally applicable solution for grid enhancement is required, SVC PLUS® provides the ideal solution. Our advanced STATCOM (static synchronous compensator) with modular multilevel converter (MMC) technology provides additional benefits compared to conventional solutions for reactive power compensation. While conventional SVC installations already provide a highly dynamic solution for voltage regulation in the power grid, the modular multilevel system SVC PLUS® is even faster and offers additional benefits. Siemens Energy also offers mobile SVC PLUS® solutions that support short-term grid changes and rapid restoration after severe incidents.

SVC PLUS® combines the benefits of static synchronous compensation (STATCOM) and modular multilevel converter technology with an optimized amount of components.

Despite its outstanding performance, SVC PLUS® requires relatively few system components, which simplifies the design, planning, and engineering of new projects. The components used for SVC PLUS® comprise proven and robust components such as industrial class insulated gate bipolar transistors (IGBT), reactors, capacitors, and in utility applications AC power transformers.

Thanks to modular multilevel converter (MMC) technology our SVC PLUS® offers great flexibility regarding design and layout of converters and substations. The modularity and the low number of system components also reduce commissioning time compared to complex conventional SVC systems.

Fastest response – efficient solution

The standardized component design allows minimized engineering efforts and provides an overall fast, efficient, modular, and cost-effective solution.
The SVC PLUS® control with its most advanced concept offers unsurpassed speed in controlling the IGBT semiconductors to precisely generate the desired flow of energy between the converter and the feeding network.

Small footprint, huge performance

The SVC PLUS® is an advanced STATCOM (static synchronous compensator). By using the voltage-sourced converter (VSC) technology based on Siemens Energy modular multilevel converter (MMC) design, it offers high economical and technical flexibility by its modular design. The footprint of an SVC PLUS® installation is smaller than a conventional SVC installation of the same rating, by up to 50 percent.

Reduced project duration

In order to reduce the civil work effort, Siemens Energy developed the containerized SVC PLUS®. The solution requires no building and less installation effort. Furthermore, the containerized design results in lower project execution time. The containerized SVC PLUS® includes the matured and proven technology of the SVC PLUS® with the best grid stability performance and a small footprint.

Grid stabilization – anywhere, anytime

The mobile STATCOM is Siemens Energy’s multi-tool for transmission grids that enables temporary grid support and grid resilience against emergencies. The preconfigured SVC PLUS® container combines major components in one housing and enables “plug and play” cable interconnection. A reactor container that contains the reactor coils including conventional bus bar arrangement complements it. The mobile STATCOM is the optimal solution for rapid service restoration after severe incidences, line rework, and grid changes, for example during power plant shutdowns.
