  1. 1. Distribution Related Engineering Asset Management System (DREAMS) P. Mukherjee Dy. General Manager IT - New Initiatives 7th October, 2013
  2. 2. CESC – Electricity Generation & Distribution Company Serving Calcutta & its adjoining areas since 1897. The electrification of Calcutta took place 17 years after New York & 11 years after London. The Calcutta Tramways switched to electricity from horse drawn carriages in 1902. CESC now belongs to the youngest & one of the most vibrant industrial houses – RP - Sanjiv Goenka Group since 2011.
  3. 3. CESC – Electricity Generation & Distribution Company Licensed Area of 567 sq. km. Total Generating Capacity : 1225 MW Peak Demand : 1900 MW Average Demand : 1600-1700 MW Total Low Tension Consumer Base : 27.20 Lacs Total High Tension Consumer Base : 1726
  4. 4. CESC’s Experience Earlier Scenario : Unstructured and non uniform practices followed in maintaining records of Asset and their up-keep. CM & CBM were mostly not supported. Leading to disproportionately more maintenance than planned maintenance . unplanned Difficulty in estimating maintenance cost and analyzing maintenance performance. Solution : CESC’s Asset Management Software. Distribution Related Engineering Asset Management System (DREAMS)
  5. 5.  Features and Functionalities of DREAMS Integrated Asset Register of major electrical plant and equipment in use including allied assets such as Substations building, premises and yards. Maintenance Management functionalities encompassing Preventive Maintenance(PM) Status & Condition Monitoring (SM&CM) Condition Based Maintenance (CBM) Repair/Breakdown Maintenance (BM) Abnormal Observation (AO) Carrying out all maintenance activities as per SM,CM,PM regimes stored in the system. Analyze, interpret and maintain the transformers with the help of the Dissolve Gas Analysis (DGA) Dash-Board tool integrated with the system. Handing Over Taking Over (HOTO) Module for managing assets during creation, installation and commissioning before handing over to Operations & Maintenance (O/M) group.
  6. 6. DREAMS ASSETS CONSIDERED  Power Transformer  33/0.4 kV Earthing Transformer  33/0.4 kV Auxiliary Transformer  Indoor Switchboard  Outdoor Circuit Breaker  Outdoor Isolator  Outdoor CT  Outdoor VT  Distribution Transformer  Outdoor Lightning Arrester  Ring Main Unit (RMU)  Premises  Neutral Earthing Switch  Outdoor Cable Sealing End  Battery  Battery Charger  Capacitor Bank Total No. of Assets as on date : 24578
  7. 7. DREAMS  CODIFICATION OF ASSETS  An algorithm was formulated to assign an 8 character unique code to all assets  The left most character signifies the Super Category like Power Transformer etc.  The next left most character denotes the Primary Voltage like 220KV etc.  The next five digits from left is a unique serial number  The right most character is used to differentiate amongst assets of same primary voltage but with different secondary voltage.  Super Category : Power Transformer  Super Category : Distribution Transformer 220/132/33 KV Power Transformer A7*****O 11/0.4 KV Distribution Transformer B3*****A 132/33 KV Power Transformer A6*****O 11/6-0.4 KV Distribution Transformer B3*****B 33/20 KV Power Transformer A5*****A 6/0.4 KV Distribution Transformer B2*****O 33/11 KV Power Transformer A5*****B 33/11-6 KV Power Transformer A5*****C 33/6 KV Power Transformer A5*****D 20/6 KV Power Transformer A4*****O 11/6 KV Power Transformer A3*****O 6/3.3 KV Power Transformer A2*****O
  8. 8. DREAMS  Asset Searching    ASSET REGISTER Assets searched using different criteria such as category/location/make/name/Asset No. All criteria appear on the upper part of left pane of the screen.  General Tab  The list of assets based on the selected searching criteria appears on the right pane.  All the attributes displayed alongside the asset no. with a scrolling facility.
  9. 9. DREAMS  Asset Sorting & Filtering  ASSET REGISTER  Sorting of Assets based on the values of any attribute in ascending/descending order.  Application of Filter on the values of any attribute of Assets.
  10. 10. DREAMS  Health Tab   ASSET REGISTER Indication of health of any asset through color codes based on the last observations from SM/CM/AO. ‘RED’ -> URGENT ’BLUE’ -> IMPORTANT
  11. 11. DREAMS  ASSET REGISTER  Maintenance Tab  Display of schedule for forthcoming maintenance activity (SM/CM/PM) as on date through color codes based on the periodicity as mentioned in the maintenance Regime. ‘RED’ -> OVERDUE ’BLUE’ -> scheduled within one month.
  12. 12. DREAMS  MAINTENANCE FUNCTIONS  Status Monitoring (SM)  Monitoring of assets through visual inspection.   Urgent/Important observations posted in the system. Job Allocation & Attending to the job by O&M engineers.
  13. 13. DREAMS  MAINTENANCE FUNCTIONS  Condition Monitoring (CM)  Monitoring of assets by measurements through Intrusive & Non-Intrusive activities.   Non-Intrusive CM (e.g. Thermo-graphic Scanning etc.) measurements posted in the system.   Non-Intrusive CM Re-measurement done again. Intrusive CM measurements (e.g. IR & PI Values etc.) are taken & posted by O&M departments. Job Allocation & Attending to the job by O&M engineers.  Non-Intrusive CM
  14. 14. DREAMS  MAINTENANCE FUNCTIONS  Preventive Maintenance (PM)  The Preventive Maintenance (PM) done by O&M departments as per the schedule mentioned in the PM Regime.
  15. 15. DREAMS  MAINTENANCE FUNCTIONS  Maintenance Regime  The SM/CM/PM Regime for different categories of assets are stored in the system.
  16. 16. DREAMS  MAINTENANCE FUNCTIONS  Queries & Reports  There are a host of queries & reports which caters to the diverse requirements across all user departments.
  17. 17. DREAMS  MAINTENANCE FUNCTIONS  Dissolve Gas Analysis (DGA) Dash Board   The results of gases (CH4,C2H2,C2H4 etc.) from oil samples of Power Transformer posted inside the DGA Dash Board. Six different interpretation methods such as :- IEC Reference, ROGER’s Ratio, DORNENBERG’s Ratio, Key Gas Method, Combustible Gas Method, Permissible Concentration Gas Method used to interpret the health of the transformer.
  18. 18. DREAMS  MAINTENANCE FUNCTIONS  Dissolve Gas Analysis (DGA) Dash Board   The results of gases CH4,C2H2,C2H4 can also be plotted on Duval Triangle . Trend Analysis of dissolved gases through Line & Bar Chart is also possible.
