Asset Health Management - Vision We are masters of our system and its assets. (Finally!... and in a time and galaxy not so far, far away) We know the condition of all our assets, what to do about it, and when to do it. 29
Problem Statement Aging asset population combined with pressure to reduce operations and maintenance costs AEP system wide populations: 33% of transformers in service more than 50 years old 34% of circuit breakers in service more than 30 years old Current policies dictate that all equipment gets maintained evenly on time based schedules Health of equipment is not factored into the prioritization of maintenance spend Standard practice is to run equipment to failure which increases the chances of unexpected outages and decreases reliability Maintenance and failure documentation exists across multiple platforms Analysis of existing data requires custom time-consuming queries Failure prediction and root cause analysis is not automated and requires manual data analysis by equipment experts Reliance on manual inspections and manual data entry exposes AEP to possible compliance based fines
Asset Health Center General Overview Purpose of the Asset Health Center (AHC) Prevent failures Optimize maintenance Prioritize asset renewal Transformational technology Convergence of operational & information technology Automates condition analysis, recommends actions Determines health index and remaining life Maintain on condition rather than time interval Leverages existing infrastructure & data Implementation Development of platform under way Monitoring included on new equipment Retrofit monitoring in stages to existing equipment 31
Asset Health Business Case Near Term Benefits Capital saving benefits based upon avoidance of unexpected failure costs and failure prevention Improved awareness and decision support for asset renewal (Capital) spending Avoid/redeploy maintenance (O&M) cost via condition awareness Standardization of maintenance tracking, data processing, and failure reporting Increased knowledge of our fleet and the availability of real time health assessments (event analysis, highlight outliers, and trends of interest) Reduce compliance risks Long term vision New installations of transformers, breakers, batteries are currently being standardized with monitoring packages A monitor retrofit program will be proposed in 2013 goal is to equip all existing EHV equipment with monitors over 10 years. Continue to adapt the solution with new monitoring sensors, data sources, policy modifications, etc. As technology matures sensing & decision tools benefits rise x n
Asset Health Center - Principles Do no Harm Commit to solving the problem Leverage what already exists on system Automate inspection/test procedures in real time Build standard sensors into all new devices Refit existing assets with sensing in progressive stages Develop platform focusing intelligence centrally Deploy relevant, practical sensing locally Relevant - Target top failure modes per equipment class Practical - Simple, resilient, low cost, low/no maintenance Note: These apply to AEP, US largest Transmission owner, spread over 11 states, 3 RTOs, with 3500 substations, 5500 transformers, over 11,000 breakers and whose service area is largely rural. 33
Asset Health Center Solution Asset Health Center Diagnostic Monitoring and Analysis Program AEP/ABB Technology Alliance A 4-phase 2 year project that will produce a collaborative developmental solution that leverages AEP s and ABB s subject matter expertise and allows AEP to substantially define use cases for the industry Program will analyze transformers, breakers, and batteries across the transmission system Solution involves web-based tool that Transmission personnel can access via AEP Intranet Trending of data from several sources Solution provides unique visualization tools that can be tailored to variety of audiences: asset renewal, maintenance planning, failure reporting, Transmission Leadership
Asset Health Center Technology Overview Asset Health Center Algorithms
Asset Health Center Algorithms Co-developed by AEP and ABB Based on industry standards, historical information, and failure studies Can analyze different sets of data with unique sampling rates Can assess the current health of an individual asset or measure against an asset family
Available Data Sources Nameplate, inspection, maintenance, and failure data available in ISIS, test files, Doble DTA Web. Will allow trending of historical data. Real time SCADA data such as loading, temperature, and operations will aid in the long term health assessment of equipment Real time sensors can automate maintenance and inspection functions and provide evidence for equipment failure prediction.
AHC Solution User Interfaces Web-based interface available to all Transmission personnel Can view asset condition for various levels of organization Real time alarming capability for field personnel Asset health prioritization for maintenance planning users Identify remaining useful life for asset renewal planning Can view trends for business management functions
Monitor What Matters Most Transformers EHV: leading failure cause is dielectric partial discharge is critical (PD) Dissolved gasses in oil Oil quality/leak detection: dielectric qualities, moisture, level, leaks Core & Coil: oil and winding temperatures, SFRA, thermal image profile Accessories: Bushings (C, PF/tand, PD); pumps, fans Gas Circuit Breakers Mechanism timing, motion, motor/pump starts, current draw (force) Contacts arcing time, wear/condition metrics Insulating medium gas pressure, density, moisture, quality, leak detection Controls operating coil current draw signatures Batteries Battery string V(float) and I, connection to load, connection to charger Individual cell temperature, electrolyte level, conductance Monitor Parameters Relevant to Trouble Causes and Practical to Maintain 39
Reflections Past Monitoring Experience FOCUS Targeted what s easy not what matters most INSTALLED COST Not scalable across enterprise O&M EFFORT Excessive attention required PERFORMANCE Unsustainable and ineffective SOFTWARE/FIRMWARE Weak organization, automation & use of existing assets Prior Asset Health/Real Time Monitoring Techniques Miss the Mark 40
