FACTS
Our high power FACTS product platform breaks new ground in the provision of high-power density, high-redundancy reactive power compensation.
Superior levels of availability meet the stringent requirements of large-scale renewable energy projects and critical electricity transmission and distribution applications. In addition to its built-in redundancy, the solution offers self-starting and voltage-balancing without the need of an external power source or equipment.
The FACTS platform is at the pinnacle of innovation in high-power semiconductors and converter topologies. Its proven capabilities continue to attract much attention from utilities and renewable energy organisations handling challenging large-scale projects. Operating references include Ørsted's Race Bank and Burbo Bank windfarms in the UK as well as the Lake Turkana Wind Power Project in Kenya, PGCIL projects in India and multiple wind farm connections in Australia.
RXHK is dedicated to ongoing innovation in power engineering solutions. The FACTS platform evidences how that commitment translates into heightened capability and reliability.
Technical details
The FACTS family of products deliver the ultimate in Flexible AC Transmission Systems. It brings major advantages surrounding reliability as well as improved dynamic performance, extended operating range and an adjustable power factor at the point of common coupling. The transformer-less device uses cascading multiple single-phase H-bridge PWM converters in each phase. Its AC voltage is almost perfectly sinusoidal, so it requires no harmonic filters.
Core capabilities include rapid response to disturbances and smooth voltage control over a wide range of operating conditions. Its significant built-in redundancy underpins availability exceeding 99.6%.
