For more than 20 years, we have been assisting railway companies in electrifying their network, enabling modernization of aging infrastructure and adaptation to increased traffic while enhancing reliability and network availability.
We offer decades of expertise in the development and installation of power electronics systems to support the electrification of railway infrastructures worldwide.
Our proven technologies and comprehensive range of services—from simulation and optimization of converters to long-term service agreements covering the entire equipment life cycle—provide the right solutions to address the current challenges faced by rail companies.
High Voltage Boosters stabilize and maintain catenary voltage at functioning levels for the rolling stock, with little impact on the already installed substations and without requiring a new grid connections.
An SFC connects a three-phase distribution or transmission grid to a single-phase catenary network. SFCs are also used when the grid network supplying the rail line has limited power capacity.
A load balancer connects to the supply grid and typically includes a three-phase Static VAR Compensator (SVC) or an MMC-based STATCOM. It mitigates negative sequence currents by injecting power between phases to counteract voltage unbalance.
Integrating renewable generation with battery energy storage between the transmission/distribution grids and railway grids can help both sides to meet growing energy demand, improve reliability, and address the complex market needs.
The qualities and benefits of the Modular Multilevel Converter (MMC) extend to the HVB, STATCOM, and SFC, as they incorporate MMC technology as a key component in their design, enhancing their efficiency and operational capabilities.
Easily adaptable to custormer needs, transformerless or with simple distribution transformers increasing system availability.
For both the catenary and grid, including, harmonics decoupling, power factor correction, voltage balance and energy buffering stored in distributed submodules.
Allowing reduced maintenance and repair times.
Easily integrated into MMC topologies, offering enhanced reliability and availability and allowing substations to operated unmanned and remotely.
