Henryk Schneider – SP-AusNetSteve O’Donnell – Realtime Results

Agenda• About Us• Migration to PI System 2010• Projects

– Wiredown/SWER Events/BrownOuts– Load Profile Analysis– Windows Services

About SP AusNet• Diversified energy business• $7 billion electricity & gas network• 1.2 million customers

What we do• Managing three key Victorian energy networks

– Electricity Transmission Network• 13,000 high voltage towers• ~6,580 km of transmission lines

– Electricity Distribution Network• 650,000 customers• Network spans 49,500 kms across an area of 80,000 sq. kms.

– Gas Distribution Network• 620,000 customers• Network spans 10,000 kms across an area of 60,000 sq. kms.

Realtime Results• Started with the Asset Condition Management project in 2006

– Dynamic Lines, Transformers and Asset Health• Continued with additional projects for

– Weather Warning System– Gas Advisor and Leak detection system

• Background• 34 years in Process Control and Process Management Systems• 26 years with the PI SystemTM

• 22 years active software development• Focus is advanced value-added PI applications for clients

Upgrade to PI 2010• v3.4.380.36 --> v3.4.385.77• Drivers

– end of life hardware– performance– archive storage– software upgrade

System info• 13 servers (Windows 2003)• Point count 370,000• Module count 7,300• Archive storage 800GB• 1000 archive files online

Products used• PI Server• PI ACE • rtWebParts• rtAlerts• PI Interfaces - ESCA HabConnect, PI to PI, HTML, PerfMon, SNMP, Ping,

TCPResp, RDBMS, PIOLEDB• PI Datalink• PI Processbook• Windows SharePoint Services 3.0• MS SQL 2005• MS SQL 2005 Reports• PI SDK applications

Key Changes• 32 bit -> 64 bit environment (Windows Server 2008 R2)• Module DB -> Asset Framework 2010• rtWebParts -> PI WebParts 2010• rtAlerts -> PI Notifications 2010• PI Datalink 3.1 -> 2010 *• PI Processbook 3.1 -> 3.2 *• WSS 3.0 -> SharePoint 2010 Foundation• MS SQL & Report Server 2005 -> 2008 • MS Visual Studio 2005 -> 2010

Approach• Staged implementation around each system component

– Install– Migrate software/database– Run in parallel– Test & Verify – Cutover

• Advantages– Low risk– Minimised impact on users– Rollback simple by switching users/apps back to old system

Communication• PI Bulletin newsletter• Pre and Post cutover

information & instruction e-mails.

• 200+ users

Lessons Learned

• Memory usage & File System Cache (FSC) under 64bit environment – OSIsoft KB Article # KB00784

• AF Collective (Replication) – can’t write to AF database when Primary is not available.

v3.4.380• PI Interfaces User Guides• Tech Support• Realtime Results• vCampus

Recent AF based Applications• WireDown Events• SWER Step Events• Device Operations• Load Analysis• Consumption Summaries• Data Transfers• Gas Logging Meter Management• BrownOut Analysis

Wiredown/SWER Events Project• Problem

– Power lines in distribution network fail periodically– Need to detect and alarm these events urgently

• Proposal– Use data from the field devices to detect failure in

realtime• Projects are in Trial/Evaluation mode

Wiredown/SWER Applications• Separate Windows Service applications

– .NET 4 based using VB.NET• AF Template driven

– 104 Substations, 365 Feeders,2237 devices– Not ACE based

• Primary/Standby

Asset Definition

Template Driven

Field Devices• Circuit Breaker/Feeder Relays (F650, SR760)• AutoReclosers

• ACR’s (Form 5, Form 6, & RC10)

• Single Wire Earth Return AutoReclosers• SWER’s (RC10S and Nulec)

• Sectionalisers• SEC (GSS100 & CAPM5)

• Data received via SCADA

Device Definition

Application Device Uses• High Voltage Load analysis• Substation Load Analysis• Consumption Summary• WireDown Analysis• SWER Step Event Analysis• Fire Risk Analysis

Devices in AF• Check made for new tags• Device elements automatically created

– New device added when new tag found– Based on template

• Trigger values calculated when sufficient history is available (~ 1 week)

• Device elements used by many applications32

WireDown Trigger Condition

Specified Period (mins)

Calculated Trigger Value (Amps)

Send Email Alarm

(based on Time weighted average data)

WireDown Conditions• Important to eliminate false positives

– Otherwise ignored by Control Room• Filter out several conditions

– Abnormal Load switching– Parallel events– Relay testing

• Email Alerts issued for various cases– Embedded trends for fast assessment

WireDown Earth Fault Alarm Email Alert

Abnormal Load Switch - Resolved

Real WireDown Example

SWER Step Change Analysis

Alarm sent after specified

duration

Calculated Step Change exceeded (Amps)

Analysed all steps over last 60 days to calculate Step trigger value for Device

SWER Earth Fault Email Alert

Load Profile Project• Problem

– Planners need to know what power is going through their Pole transformers (aka Substations)

– Need to aggregate usage via Smart meter data– Simple tool required for analysis

• Proposal– Combine Oracle and PI data to analyse data– Perform calculations for 60,000 meters

• Summaries for Weekly, Yearly data• Calculation run over 3 – 4 days

– Provide Web based tool for planners

Web site for Load Profile Analysis

Search by Name or NMI

Select Time to see trend

Plot Load and Frequency

Load Plot

Frequency and Duration Plots

Applications Settings via Web page

Application Management Project

• Problem– Growing number of Windows Services installed– Installed in Primary/Standby configuration– Need to monitor performance and track activity

• Proposal– Define Application template for common approach– Provide Element Relative display for PI System Manager

Application Management• Currently running 9 Windows Services

– Performing a variety of tasks• Consumption Summaries• Automated Data Transfers via FTP/Email• Substation Load Profile calculations• Tracking Gas Corrosion Loggers• Tracking Wiredown and Earth faults

– Running in Primary/Standby mode• AF used to monitor Services

Applications in AF

Application Template

Application Monitoring via ER displays

Conclusions• Trials have proven effective

– Real and impending faults identified early– No cost benefits done as yet

• AF is very versatile for developing applications– AF Templates reduce significant re-work
