Explore our primary selection of state-of-the-art Static Var Generators (SVGs). These modules have been optimized to meet Sweden's stringent grid code standards (Vattenfall and Svenska Kraftnät requirements), delivering high energy efficiency and rapid reactive power compensation under extreme climate conditions.
As Sweden accelerates its transition toward a fossil-free future by 2045, the national grid is undergoing profound changes. The rapid expansion of wind energy in the northern regions (SE1 and SE2) coupled with massive load demands from new green industrial initiatives in the south (SE3 and SE4) has created significant transmission bottlenecks. Projects like the HYBRIT fossil-free steel initiative, large-scale battery manufacturing plants, and regional hyperscale data centers require incredibly stable power grids.
Historically, rotational inertia from massive thermal and nuclear generators provided natural voltage and frequency stability. However, the decommissioning of nuclear capacity and the integration of highly volatile renewable energy sources mean that modern power systems must rely on active, fast-responding power electronics. This is where Static Var Generators (SVG) act as critical infrastructure components.
Unlike traditional capacitor banks that degrade over time and act slowly, SVGs utilize advanced insulated gate bipolar transistors (IGBTs) to inject or absorb reactive power dynamically. This millisecond-level response is essential to counter voltage dips, prevent sub-synchronous resonance (SSR), and maintain power factor metrics close to unity (1.0) under Sweden's strict national grid codes.
Swedish transmission system operators enforce stringent regulations regarding reactive power exchange and harmonic distortion limits (typically adhering to EN 50160 standards). Non-compliance leads to severe financial penalties and can disqualify renewable generation assets from grid injection.
With a team of highly qualified engineers and electrical experts, Sowest Electric delivers customized SVG cabinets capable of operating in low-temperature environments typical of Swedish winters (-40°C outdoor ratings).
Using high-speed DSP control systems coupled with world-class IGBT switches, our SVGs respond in under 10 milliseconds, making them perfect for arc furnaces, heavy duty cranes, and automated mining operations.
Our comprehensive portfolio stretches from compact modular low-voltage 10kvar systems for local commercial EV charging stations up to massive containerized 12kV high-voltage SVG solutions for substation levels.
For many years, Swedish industries relied on passive Static Var Compensators (SVC) containing capacitors and reactors. However, capacitor banks are subject to grid voltage degradation (their capacity output drops quadratically with a decrease in voltage). In contrast, a modern SVG operates as a controlled current source. Even when grid voltage drops severely, the SVG can continue to inject its full rated reactive current to support grid recovery. Furthermore, the risk of resonance with existing grid impedances is entirely eliminated with our active SVG architecture, preventing premature component wear.
