This document discusses the key components of ETAP's Advanced Distribution Management Systems (ADMS). It describes the Oneline View (OLV), Distribution View, and Feeder View for modeling electrical distribution systems. It also covers themes like load allocation, which utilizes real-time system data to calculate power flows; Fault Location, Isolation, and Service Restoration (FLISR); and other ADMS engines for functions like volt-var optimization, switching optimization, and reliability statistics. The document provides overviews of the different views, load allocation architecture and process, and some of the advanced analysis capabilities in ETAP's ADMS software.

• Oneline View (OLV)
• This is the standard view used in ETAP.
• It primarily contains components above the feeder breaker (Substation and
Transmission level)
• Each Substation is a Composite Network
• There are still multiple presentations

• Distribution View
• Geospatial View
• Only contains feeder breakers and below.
• Can include maps from Google / Bing
• Only one Presentation

• Feeder View
• Automatically rendered schematic view of each feeder
• To Create – Right Click a Feeder Breaker in Distribution and select View

• Shared Components
• Standard OLV components
• Can be used in OLV, Distribution, and Feeder View
• Non-Shared Components
• Only visible in Distribution and Feeder Views
• Used to support extremely large distribution systems
• Lumps lines as Equivalent Circuits (EC) in OLV so it is less
taxing on the engines (UBLF, etc)

• Import GIS Model
• Typically the first step is to import the GIS model.
• This is the easiest way to setup a system however can’t always be done
in this way due to project constraints.
• CIM 15, KML, other
• Required Updates for Offline Engines
• Substation Assignment
• Feeder Breaker Assignment
• Create OLV

• Purpose of Load Allocation
• Utilize Real-Time data to calculate the power flows of the system
• Real-Time Data Used
• Feeder Data: Required
• Voltage Magnitude (Phase A, B, C)
• Voltage Angle (Phase A, B, C)
• MW Magnitude (Phase A, B, C)
• Mvar Magnitude (Phase A, B, C)
• Feeder Breaker Status
• Distribution Transformers: Optional
• MW Magnitude (Phase A, B, C)
• Consumers: Optional
• MW Magnitude (Phase of Consumer)

• Load Allocation Architecture
• PM Server writes Real-Time Snapshots to MongoDB
• ETAP Provides Connectivity Model to Load Allocation
• Load Allocation Engine reads RT Snapshots and writes LA
Snapshots
• Other ETAP consoles Read LA Snapshots

• Load Allocation results
• Technical Losses (heat, etc)
• Non Technical Losses
• Support for Aggregation of:
• Average
• Minimum
• Maximum
