The presentation will cover improvement in reliability of distribution feeders by distribution automation design. Due to frequent faults, distribution system customers experience commercial and material losses. In this presentation I will discuss the methods to calculate reliability of distribution systems, and how Distribution Automation will improve the reliability of distribution systems with reliability indices being used as a measurement tool. We will cover how data on past outages can be used to estimate outage time. I will provide examples of how distribution automation was applied, and the techniques developed to calculate, and measure improvement using reliability indices and discuss the expected improvements.

As the renewable generation space continues to grow, a unique challenge is presented for the operation and maintenance of medium and high voltage transformers. Variable generation patterns and weather conditions cause transformers to experience abnormal operating parameters resulting in irregular dissolved gasses levels and failures. This unique set of operating parameters requires innovative monitoring techniques and approaches to achieve increased generation availability while maintaining reliability of the overall site. This presentation will provide an overview of the unique operating parameters transformers experience in renewable applications and solutions used to maximize reliability and availability.
