Power Integration


Recently, EAC Systems (AUS) personnel, participated in a long term project involving Off Grid Power System integration of a large mining project overseas in a developing country. As part of the project deliverable, three independent power stations were combined into one supply grid. Challenges involved with this project were that all three power stations had varying types of prime movers and generators that had to become one station spread over several square kilometers. The task at hand was to implement a centralized control system to provide management of all stations independently and collectively. Aspects of this project involved the ever evolving onsite commissioning and development of SCADA, control systems, communications networks, protection systems, automated switch-gear and implementing alternative philosophies to achieve the most viable outcome. All required to ensure multiple package vendors arrived at a workable solution for the end user.


The End users station configuration was made up of:

  1. 20+ Megawatt Prime moving Isochronous station
  2. 10+ Megawatt light duty base load station Capable of Adaptive Base load sharing
  3. 14+ Megawatt mixed duty station capable of Isochronous, Base, Adaptive load sharing
  4. Statcom Unit
  5. Harmonic Filter


The power stations output voltages ranged between 6.6kV, 11kV, 33kV, and a number of step up transformers and a multitude of protection relay. All of which included the installation and commissioning of a new site wide communications network infrastructure.


The key to this integration implementation success  was collectively working on solutions provided by multiple vendors from around the globe and ensuring a reliable, robust and redundant power network with total flexibility was available to maintain the the end users operational requirements. Also


Balancing of the system to ensure the most cost effective and fuel efficient power production is achieved.

It was a great experience to be heavily involved with this project scope and we hope the end user has many years of trouble free power generation from the completion of this project.
