SVC PLUS, modular multilevel converter STATCOM up to ±400 Mvar (stationary, containerized, mobile)
SVC PLUS® is a voltage-source converter (VSC) STATCOM with a modular multilevel converter (MMC) topology, up to ±400 Mvar per arm. It is used for fast voltage control, improved dynamic stability and power quality in grids with renewables. The device is built as a stationary, containerized or mobile unit.

Description
SVC PLUS belongs to the family of flexible AC transmission systems (FACTS) and controls voltage in both steady-state and transient conditions. The multilevel output voltage waveform sharply reduces harmonic distortion, so the bulky filters that thyristor SVCs cannot do without are not needed here, and the footprint is much smaller. Connection to a grid of any voltage class is made through a transformer. According to the company, more than 150 SVC PLUS systems have been commissioned worldwide, of which more than 30 are containerized, and more than 24 thousand power modules are in operation. The same platform underlies SVC PLUS FS and the mobile STATCOM.
A single converter arm is rated for up to ±400 Mvar. An example of a large installation is the Kriftel substation in Germany, where an SVC PLUS of ±300 Mvar at 380 kV works together with a 300 Mvar mechanically switched capacitor bank with damping circuit (MSCDN). The design is fully enclosed, with active harmonic filtering, and availability exceeds 99 %.
The containerized SVC PLUS consists of standardized blocks of ±25, ±35 or ±50 Mvar per arm, up to ±150 Mvar in total. The modules leave the factory tested. The converter core contains the control, protection and cooling systems; reactors, auxiliary-supply containers and battery containers are supplied separately, and a power transformer and a containerized GIS can optionally be added. No building is required, so the permitting procedure is simpler and commissioning is faster. The containers operate at −30…+40 °C, optionally at −40…+45 °C, are suitable for seismic and coastal areas, and have a service life of more than 30 years.
SVC PLUS Mobile is mounted on wheels. It is transported and put into operation within a few days to temporarily support the grid during line reconstruction, after faults or when operating conditions change.
The functions include voltage control in grid-following mode and optionally grid-forming mode, control of external capacitor and reactor banks (MSC/MSR), active harmonic filtering, damping of electromechanical oscillations and control of negative-sequence currents. For the SCADA system there are IEC 61850, DNP3 and IEC 60870-5-104/101 interfaces, and the cybersecurity architecture meets national requirements such as NERC CIP. The installations operate in transmission and distribution grids, at connection nodes of wind and solar plants, at industrial consumers with rapidly changing loads and in data centers.
