Primary distribution automation

Primary distribution substations are the building blocks for any distribution grid. Hitachi Energy has been automating those substations ensuring highest interoperability, thanks to international standards like IEC 61850, and providing grid operators and owners with the highest efficiency and increased productivity. Without adequate protection, those substations can quickly come tumbling down. Hitachi Energy has been preventing that happening successfully during the last 100 years, with protective relays and breakers connected over bulletproof telecommunication solutions.

The application of modern automation concepts into the primary distribution substations is enabling utilities and operators to see better and deeper within their grid. Implementation of automation into a distribution network allows among others to:

  • Increase grid visibility
  • Reduce outage frequency and time
  • Improve grid reliability and efficiency and
  • Integrate more distributed energy resources

Modern automation nowadays is digital. So digital substations can increase controllability, facilitate the integration of intermittent renewables and improve safety by replacing conventional current and voltage transformers with modern current and voltage sensors. Hitachi Energy Automation enables the digitalization of the grid so that our customers can improve reliability and ensure safe and clean energy supply to their consumers.
