Six substations to keep light rail on track

Six substations to keep light rail on track

The Gold Coast’s Light Rail Project is one step closer to reality after automation technology group ABB was awarded a three-year contract to provide maintenance supervision services for six medium-voltage DC traction substations.

The agreement between KDR Gold Coast, a consortium member for GoldLinQ – the operators of the light rail link – provides a customised maintenance and service solution that will ensure the six traction substations continue to provide reliability and power for the light rail system. Safeguarding the performance of this equipment is essential to meeting the transport needs of more than 18,000 G:link commuters who will rely on the rapid transit system everyday.

ABB said will utilise advanced diagnostic and repair practices to provide 24-hour support with a guaranteed response-time, annual preventative maintenance and access to Neplan diagnosis for six transportable substations. Neplan is a planning and information system designed for managing, analysing and optimising all voltage levels of electricity networks.

The collection and analysis of condition and diagnostic data throughout the lifecycle of equipment is permitting a shift from time-based to condition-based maintenance, maximising availability and reliability while also reducing the costs of interventions and the associated downtime.

The six substations are rated at 11kV AC/750V DC and are housed in transportable outdoor buildings with key technologies integrated. These products include rectifiers, DC switchgear, SafePlus medium-voltage switchgear, dry-type rectifier and auxiliary transformers, leakage current monitoring systems and auxiliary equipment.
