1 External Tables How They Benefit YOU! Eric Jung

2 What are the External Tables? A database(s), outside of WindMil, but connected to WindMil Data Multiple database types allowed in 8.2 Oracle MS SQL Server MySQL Externals will run on an existing DB instance

3 What Can They Do? Not a Sta,c Data Silo Engineering Key to data integra,ons A highway that travels both direc,ons

4 What Informa,on Can Be Exchanged? Model data Standard model data ELUA calculated fields Polygon based fields External data External DB WindMil Customer Data: Billing rates, Descrip,on, Member names etc. Equipment Data: Maintenance, purchase info etc.

5 How To: A Setup Overview 1. Database Connec/ons Connected DB s 2. Linked External Tables Connected Tables & Fields 3. Table Uses Connects WM Elements Types to Ext Tables 4. Field Mappings WM fields mapped to Ext fields

6 Linked External Tables Tab Used Fields are available to WM Map WM fields to Ext Use Ext field in WM Primary Key should remain CMID Must be unique!

7 Table Uses Tab Connect WM element type to Ext table Note: Mul,ple connec,ons to Consumer elements

8 Field Mappings Tab Table External Table name Field External Table fieldname WindMil Field Maps WM field to External Example WM field max possible fault mapped to LL_Fault field in External Tables

9 Update All Fields Prompt to update all Always Yes Updates ALL Mapped fields This takes,me: Update to map Fault currents = 385,636 Opera,ons

10 Shared Engineering Data - Outputs Three Major Categories Base Windmil fields Electrical data Polygon fields Geospa,al info ELUA based fields Custom calculated fields

11 Useful Base Windmil fields Connec,vity Feeder Source Fault currents Equipment Specific equipment Maintenance records link

12 Polygon Fields Open ended Any projected shape file Applies chosen fields from shape file to model elements Debate Windmil vs GIS import If u,lity has GIS, where should data be sourced? OPINION: experience shows this tends to be faster in WindMil than WMM

13 ELUA Fields Sky s the Limit! Calculated fields based on ELUA script Limited only by one s imagina,on and ability Examples: Further connec,vity Upline OCR s, Upline Regulator, Upline transformer KVA Nearest element of Type

14 Model Data Inputs Anything with one- one rela,onship CIS info Metering mul,pliers Billing Rates AMI info Outage counts Signal strength

15 Input limita,ons No criteria based searches IE. Pull load data for par,cular date and interval It is unrealis,c to avoid working in DB IE. Load import requires load be stored in table with one entry per element Calcula,ons/selec,ons must be done in DB applica,on

16 Billing Story I received this service order. It says it s in my territory but it s actually in Big Al s territory. What s going on? The town of <insert town name in need of addi,onal tax revenue here/> has just enacted a tax on electricity. What accounts should be coded with this new tax?

17 Examples Useful for Billing Upline feeder SEIEC delineates territory by Feeder Model changes automa,cally update data in External tables Separate table Feeder2Territory automates excep,ons between CIS and WM. City limits Determines who is affected by local sales tax Automa,cally updated - Polygon generated field

18 Examples Useful with AMI Upstream opera,ng device ELUA field that finds the next upstream mul,ple opera,on device Link with AMI outage counts to find blinking zones Phasing Compare model phasing to AMI phasing Generate excep,on reports

19 Examples Asset Management OCR s, Regulators & Transformers WM provides Loca,on (X,Y) Loading info (thru KW) Specific Sekngs Maintenance data connec,on Import maintenance data into Externals Link based on element or equipment name

20 Field Stories I m trying to call in to one call for an emergency. They re asking for the township. We used to have this in our paper maps but these newfangled electronic maps don t have this. I ve got this fault that I just can t find. The recloser at the sub says the fault is 1437A between C phase and ground. Where should I look?

21 Examples Useful to Field Personnel Township name Polygon sourced field Needed for Dig no,fica,ons Polygon manager links to elements External tables maps data out for all element Phasing Fault Currents Arc Flash Ra,ngs

22 Engineering Stories <insert Coop name/> had a shorted CT on the G&T metering at one substaion. This went on for a year before it was found. They now owe over $300K in back billing due to the 2/3rds reading. How do we know this isn t happening to us?

23 Load Reconcilia,on Requires import of load and G&T metering Using model connec,vity aggregate metering data back to substa,on KWH sold Compare results to G&T KWH Purchased Compare calculated losses to actual KWH Purchased- (KWH sold + un- metered load) Security/yard lights = example of un- metered load

24 Engineering Stories Hey there all knowing engineer, we have to take out this substaion tomorrow and back feed the load. I know the temperature is supposed to be a high of 33 degrees. How can we switch this and what OCR s do we need to bypass to make this work?. Oh yeah, sorry it s already 4pm but I need to know by 6 am so I can direct the guys.

25 Engineering Stories Last Saturday I was called out on this voltage issue at the Happy Trails Campground. They were running 107V and they had 15 of those big RV s plugged into a 200A service. The rest of the 325 campsites looked like they were precy full too. Heck I even saw one guy in a pup tent with a window unit A/C s;cking out of it. What do we need to do here?

26 Load Import Shown at UC Build an accurate load model in < 30sec Requires load data housed in External tables Create a table specifically for load Populate this table with the load to import Very simple SQL script to select specific interval Requires a single entry per model element

27 Final Thoughts Data silos System dependent silos Personnel dependent silos Vision Strategic plan Best source of data fields
