1 2009 PI Seminar - PhiladelphiaPSEG T&D CBM1 PSE&G Condition-Based Maintenance Angela Rothweiler October 13, 2009 PI Seminar - Philadelphia

2 PSEG T&D CBM2 Agenda  Background  Problem  Solution Asset Registry CMMS Functional Areas Data Collection Condition Assessment & Criticality Inspection Process Example  Critical Success Factors 2009 PI Seminar - Philadelphia

3 PSEG T&D CBM3 Background  Utility Overview New Jersey Based Total Assets ~ $14 Billion Total Revenue ~ $7 Billion  Service Territory 70% of New Jersey’s population 2.0 million Electric customers 1.6 million Gas customers 2,600 Square Miles  Delivery Implementation 1999 – SAP OMS, GIS & CAD CMMS 2009 PI Seminar - Philadelphia

4 PSEG T&D CBM4  No predictive maintenance program or strategy  Significant liability risk and system outage potential from old equipment vulnerable to failure  Limited assessment tools for determining asset condition  Decreasing expertise in both field maintenance and engineering  No formalized capital spending program  Asset Information in a variety of disparate systems Asset Population by Division and Age Class Within Equipment Problem 2009 PI Seminar - Philadelphia

5 PSEG T&D CBM5 Inside Plant Electric Asset Registry  Equipment & Locations Class and Characteristics Nameplate  Maintenance Plans (56k Plans) Calendar-based Counter-based Condition-based  Notifications Damage and Cause Codes grouped by Equipment  Equipment Visibility PM Plan Cost/Hours vs. Actual CM Cost 2009 PI Seminar - Philadelphia

6 PSEG T&D CBM6 Functional Areas  Data Collection SAP Asset Information Time-Series Data Collection Application Diagnostic and Inspection Data  Asset Analysis and Reporting Condition Assessment Work Prioritization Alerts / Notifications  Maintenance Management Measurement Points Maintenance Plan Modifications Notifications Data Collection Analysis & Reporting Maintenance Management Raw data Measurement points Notification Feedback 2009 PI Seminar - Philadelphia

7 PSEG T&D CBM7 Data Collection & Consolidation PIHDW MV90 ESOC PI PI - OPC Hydran Doble SAP-PM Diagnostic data Delta-X MDT Transmission SCADA Distribution SCADA Transformer loads PI Manual Logger Weekly substation inspection SAP order history and technical object updates Transformer oil analysis Gas equipment results Breaker Tests Electrical test results 2009 PI Seminar - Philadelphia

8 MDB Hierarchy Structure

9 MDB Properties & Aliases

10 PSEG T&D CBM10 Condition Assessment Overview  Calculation Structure CA = F1(M1) + F2(M2) + F3(M3) + … Factors driven by data available Example Factors CM Cost & Count for Past 6 Months Operation Count for Past 6/12 Months Gas Analysis – Change over time Average Load over Time  Peer Groups Apply calculations by peer group Voltage, Class, Type Example Groups: 26KV – 69KV GCB 138KV+ Power Transformer LTC Vacuum Tanks 2009 PI Seminar - Philadelphia

11 Criticality  Calculation Structure CA = F1(M1) + F2(M2) + F3(M3) + … SAP Static Factors Voltage Location Replacement Cost Age  Peer Groups Apply calculations by Equipment Class Example Groups: Gas Circuit Breaker Power Transformers  Use as a tie breaker in CA evaluation 2009 PI Seminar - Philadelphia

12 PSEG T&D CBM12 Substation Inspection Process Notifications PM Orders Measurement Document Interface Triggers Order & Status Updates Data Tour CAD/PI Tour and Values Job and Status  SAP generates inspection order  CAD Auto-dispatch orders to operators groups  Operator collects inspection data via PI-ML and sends to PI  PI evaluates data and generates SAP notifications or transfers measurement document to SAP via PI RLINK PI Manual Logger database PI Manual Logger Data entry 2009 PI Seminar - Philadelphia

13 PSEG T&D CBM13 Alerts / Notifications  PI-ACE Algorithms monitor real-time & weekly inspection data  Creates s and SAP notification  Examples: Excessive LTC Operations High GCB Temperatures Low GCB Pressure Low Transformer Oil Tank Levels Low Nitrogen Cylinder Pressure 2009 PI Seminar - Philadelphia
