This seminar will cover:

 Symmetrical Components Concepts

• Provide basic training in symmetrical components, Per-Unit conversions from phase values, using base-MVA ratings, etc.

 Distribution System Overview

• Typical overall distribution system overview and how it interfaces with the overall traditional generation and transmission system.
• Basic review of hardware components: pole mounted cap banks (fixed, timer, and dynamic control), reclosers, fuses, voltage regulators, etc., and why they are needed
• Radial systems and components such as feeder tie point, operating concerns and benefits
• Networked distribution systems and components, operating concerns and benefits (Perhaps use I-Drive UG network as an example)
• Voltage Regulation concepts. Voltage control at the bus (aka PEF) and at the feeder (aka FPL), load reduction profile, Underfrequency/Undervoltage load shedding concepts

 Distribution Protection Coordination

• Starting at the substation, provide an overview of coordination alternatives between substation breaker, reclosers, and lateral fuses
• Transformer damage curve
• Coordination curves – fuses, relays, reclosers
• “Fuse Save” vs. “Fuse Blow”
• Run through an example coordination for a typical radial feeder with a modicum of reclosers and lateral fuses

 Smart Grid Concepts

• AMI/AMR
• RF Network Connections to the Meter
• Dynamic Recloser and Cap Bank Controls
• Communications to reclosers and cap banks
• Improving Power Factor at the station bus
• Dynamic load controls at the home, along the feeder (cap banks & voltage regulators), and in the substation
