Schematics  project

PG&E – WHO WE AREü Pacific  Gas  and  Electric  Company  was  incorporated  in  California  in  1905ü There  are  approximately  20,000  employees  who  carry  out  Pacific  Gas  

and  Electric  Company's  primary  business—the  transmission  and  delivery  of  energy  

ü The  company  provides  natural  gas  and  electric  service  to  approximately  15  million  people  throughout  a  70,000-­‐square-­‐mile  service  area  in  northern  and  central  California.  

ü Pacific  Gas  and  Electric  Company  and  other  utilities  in  the  state  are  regulated  by  the  California  Public  Utilities  Commission,  created  by  the  state  Legislature  in  1911.  

PG&E  – SERVICE TERRITORY

• Service  area  stretches  from  Eureka  in  the  north  to  Bakersfield  in  the  south

• 2.4  Million  Wood  Poles• More  than  141,215  circuit  miles  of  

electric  lines  (over  120,000  of  Overhead)• More  than  42,141  miles  of  natural  gas  

pipelines.  • 5.3  million  electric  &  4.3  million  gas  

customer  accounts.

WHAT IS THE SCHEMATICS PRODUCT

• Esri extension  that  works  with  ArcGIS/ArcFM

• For  PG&E  it  provides  primary  circuit  system  representation

• Easy  to  read;  quick  reference  for  primary  equipment

• Graphic  Data  is  housed  as  diagrams  in  a  standalone  database

• Annotation  is  kept  with  the  GIS  feature  as  an  added  anno  class

• Also  applicable  to  gas  systems

GIS AND SCHEMATICS VIEW

BUSINESS CASE FOR SCHEMATICS

• Replace  current  Cadd based  circuit  maps• Integrate  with  GIS  to  make  schematics  closer  to  real  time  

• Help  support  switching in  the  OMS  system• Ability  to  plot  as  needed  

SCHEMATIC DESIGN OBJECTIVES• Try  to  stay  with  a  COTS  solution  as  much  possible• Create  symbology familiar  to  current  users• Colorize  conductor  features  by  circuit  number• Provide  a  product  that  can  be  distributed  using  the  internet  (Web  Viewer)

• Keep  up  to  date  using  the  GIS  editing  process• Keep  it  easy  to  maintain  the  generated  schematics• Keep  features  relative  to  the  major  land  features    (geo-­‐schematic)

CONVERSION TASKS• Convert  existing  GIS  data  into  Schematics  diagrams  using  schematic  

engine,  and  model  rule  definitions

• Adjust  graphics  and  annotation  for  over  4,200  -­‐ 500  scale  and  100  -­‐ 50  scale  diagrams  using  predefined  specifications  and  schematic  edit  tools  

• Adjust  graphics  to  create  a  geo  schematic

• Edgematch at  all  diagram  boundaries

• Ensure  all  annotation  is  associated  to  the  correct  features  and  perform  general  white  space  management

AFTER

• Edit  using  Schematics  editing  tools

• Tech  uses  GIS  view  to  help  with  schematic  placements

CHALLENGES• Convert  and  clean–up  4,200  diagrams  on  an  aggressive  schedule• Managing  the  GIS  based  annotation  during  the  conversion  process• Provide  a  consistent  looking  product  across  all  regions• All  diagrams  were  edgematched• Address  dense  areas  (UG)  and  maintain  general  geo  positioning• 50  scale  diagrams• “Blow  up”  tight  areas  

• Come  up  with  a  strategy  to  deal  with  extremely  dense  areas  such  as  San  Francisco  (Multi-­‐view)

MULTI-VIEW SOLUTION

(OMS)• Separate  views  for  Radial,  Tie  and  Network  Conductors• Users  are  able  to  toggle  between  views  on  the  fly  

RADIAL TIE NETWORK

MAINTAINING THE SCHEMATIC DATACHALLENGES

• Only  capture  GIS  changes  that  affect  schematics  features  model  (Change  detection  tools)

• Create  a  repository  so  no  Schematic  edit  is  missed  (Geo  processing  tools)

• Create  an  Schematic  editing  environment  (Check-­‐out/Check  in  tools)  

• Keep  current  with  GIS

ACCOMPLISHMENTS

• Over  4,200  diagrams  converted  and  cleaned  by  UDC

• Successful  publication  to  PG&E  Webviewer

• Implemented  schematic  view  within  the  DMS  application  (OMS)

• Schematic  updates  within  48  hours  of  GIS  change

• Over  30,000  SUPs  processed  annually  by  UDC

WHAT MADE THIS POSSIBLE

• Substantial  and  continued  support  from  PG&E  stakeholders  and  management

• Close  coordination  between  multiple  teams  at    PG&E,  ESRI,  UDC  and  IBM

• Critical  design  input  from  many  PG&E  departments

• Solid  project  management  provided  by  all  parties  during  conversion  and  SUP  maintenance
