Grid automation solutions offer utilities a systematic approach to increasing the level of automation in power systems. Automating secondary substations leads to improved fault detection, isolation and restoration.
Grid automation control cabinets and retrofit-sensors provide a cost-efficient solution for smart secondary distribution. Today‘s distribution network includes a large amount of compact secondary substations (CSS) with ring main units (RMU), of which only a few are remotely controllable. The utilization factor of the integrated transformers is unknown, knowledge of energy flow and faults is lacking, and the quality of the distributed energy is rarely measured.
Implementing remote control, monitoring and measurement does not necessarily require replacing the entire CSS. Instead, ABB’s grid automation solutions provide a cost-efficient upgrade: a retrofit control cabinet, supporting the manufacturer’s motor operating device as well as current and voltage transformers or sensors. The control cabinet is also ideal as an add-on installation in a third-party CSS. Retrofitting improves not only the controllability, but also fault management thus improving the quality and reliability of the grid, with the support of retrofit sensors.
In addition to showing live grid automation demonstrations in the exhibition, ABB will explore the topic at the conference by presenting a project on "Energy efficient grid automation solutions for mixed overhead line and cable networks." The presentation will investigate:
