Retrofit Distribution Automation


Enexis – Drivers for Distribution Automation


Improve the quality of power distribution to reduce frequency and duration of power outages and radically decrease utility’s SAIDI figures

To deploy a retrofit solution in existing and new substations.

The automation solution had to fit 20% of the substation variations which covered 80% of utility’s network installations.

To reduce installation costs by deploying a standardized distribution automation solution, both during the installation phase but more importantly, during the replacement phase if need be.

24


Enexis – customer experience

Over 700 units rolled out Very little interaction with installers was

required in the field as everything could be pre-configured. Installation did not require a laptop.

Significant outage reduction has been achieved. Customer Minutes Lost (CML) reduced from 87+ minutes to 3–5 minutes, reaching almost 60% (instead of expected 40%).

Grids are more meshed than originally expected.

Based on this experience the utility is able to update its Distribution Automation strategy.

25

Low Total Cost of Ownership of the solution

Remote upgradability for SCADA protocols

Remote firmware capabilities to roll out security updates based on external security revision

Solution flexibility and modularity proved important as the need for increasing feeder control was revealed during the rollout phase

MV/LV Monitoring & Control


DONG energy - Drivers


DONG energy was one of the first utilities to start implementation of the smart grid plan back in 2000. Their goal was to create a MV/LV Monitoring and Control Solution for their distribution network.

Primary goal was to deploy a modular retrofit solution to fit DONG energy’s large variety of substations, some being 100 years old and others being brand new.

Second objective was to locate faults faster (earth faults and short circuit) to be able to reduce SAIDI, which required automation capabilities.

27


DONG energy – customer experience

Over 300 units rolled out (5% of substations covered with automation and 3rd Generation fault detectors)

Significant outage reduction has been achieved. Customer Minutes Lost (CML) reduced from 35+ minutes to approximately 7 minutes.

The system has been in operation for more than 10 years and is now used beyond fault detection, e.g. for network planning.
