Brochure · EN — Twelve-slide Siemens Energy presentation (CIGRE Paris Session 2024, marked "Unrestricted © Siemens Energy, 2024") introducing SVC PLUS Mobile, Siemens Energy's relocatable STATCOM. It motivates the need — rapid change in network infrastructure may jeopardize grid stability, with challenges such as emergency reaction and very short implementation time — and answers it with a mobile, low-footprint STATCOM with a relocation time of about 2 weeks for fast grid stabilization and restoration. Two conceptual slides show why reactive power compensation is needed for steady-state voltage regulation and fast-acting voltage support after dynamic events. A plant-layout rendering names the six numbered units of the mobile plant (SVC PLUS trailer, reactor trailer, auxiliary trailer, outdoor cooler, plus power transformer and GIS trailer if required), a components slide shows the SVC PLUS circuit (coupling reactor, IGBT converter, DC capacitor) and simplified single line, and a reference slide cites the world's first Mobile STATCOM: 1x SVC PLUS, 115/230 kV, ±50 MVAr, mounted on a trailer, completed 2018 in the USA. The presentation contains no ratings table beyond that reference-project scope line — no dimensional, thermal or further electrical data is printed.
This 12-slide Siemens Energy presentation, prepared for the CIGRE Paris Session 2024 and footed "Unrestricted © Siemens Energy, 2024" on every slide, introduces SVC PLUS Mobile — "Siemens Energy's relocatable STATCOM" (cover, p.1) — opening with the hook "Have you ever thought about a moving-STATCOM?" (p.2).
Fidelity note: the deck contains no technical ratings table. The only electrical figures printed anywhere are in the reference-project scope line on p.10 (1x SVC PLUS, 115/230 kV, ±50 MVAr) and the qualitative relocation-time claim on p.4 (about 2 weeks). No dimensions, losses, standards or further ratings appear, and none are added here. Original spellings such as "Restauration" and "severe incidences" are kept as printed.
Current observations (p.3): decentral power generation; line rework and Restauration; high flexible change of network condition; Restauration after severe incidences (e.g. thunderstorms, fire …).
Challenges (p.3): emergency reaction; flexible and short time need; very short time for implementation.
The Siemens Energy mobile STATCOM provides grid stability within weeks (p.4). To operate transmission grids in known high quality: robust, flexible and fast reactive power compensation is necessary; steady state voltage regulation; transient voltage support after network events.
The answer panel on the same slide: SVC PLUS Mobile — support on STATCOM technology for fast grid stabilization and restoration; mobile and low footprint with a relocation time of about 2 weeks.
Lack of reactive power means voltage violations in steady state condition (p.6): paired day-curve charts (grid voltage vs. nominal, capacitive/inductive reactive power over morning–noon–evening–night) contrast the grid without and with reactive power compensation — with compensation, the grid voltage is held at nominal.
"… and after dynamic events in the network" (p.7): paired transient plots without and with reactive power compensation illustrate the voltage-support effect; the slide concludes there is a need to provide fast-acting voltage support.
Slide 8 — "Siemens as market leader in STATCOM technology – from now on mobile!" — shows a rendered fenced compound with the trailer fleet arriving by truck. The six numbered units of the mobile plant are listed verbatim below.
| No. | Unit (as printed) |
|---|---|
| 1 | SVC PLUS® Trailer |
| 2 | Reactor Trailer |
| 3 | Auxiliary Trailer |
| 4 | Outdoor Cooler |
| 5 | Power Transformer (if required) |
| 6 | GIS Trailer (if required) |
Slide 9 presents the SVC PLUS component circuit diagram — from the network via the coupling reactor into the converter block, which contains the IGBT converter and the DC capacitor — alongside a simplified single line with four numbered elements: 1 transformer (stepping between the HV and MV levels), 2 coupling reactor, 3 SVC PLUS, 4 control.
| No. | Element in the simplified single line |
|---|---|
| 1 | Transformer (HV / MV) |
| 2 | Coupling reactor |
| 3 | SVC PLUS® |
| 4 | Control |
Slide 10 presents a delivered reference project, headed "Mobile STATCOM". Challenge: the world's first Mobile STATCOM. Scope: 1x SVC PLUS, 115/230 kV, ±50 MVAr. Solution and benefit: Mobile STATCOM system mounted on a trailer. Location: USA; completion: 2018. The slide also names the utility customer, which is withheld here per this catalog's no-customer-names guardrail.
The slide's photograph shows the containerized trailer-mounted unit in the workshop.
