Vision of DigiUtility

• The concept of DigiUtility covers both the
  physical power grid and the business process. The
  vision of DigiUtility is presented as three
  aspects, namely the digitization of grid
  controlling, automation of business processing
  and integration of company management.

10
The Definition of DigiUtility

• Grid controlling digitization
• - It requires the digitization of measuring,
  monitoring, protecting and controlling both the
  power equipments and the power system.
• The major systems involved Substation
  Automation system (SA), distribution automation
  system (DA), Digital Protection Relay (DPR) and
  Equipment Condition Monitoring system (ECM),
  SCADA/EMS, Outage Management System (OMS),
  Automatic Meter Reading system (AMR) and Load
  Control system, etc.

11
The Definition of DigiUtility

• Business processing automation
• It presents the automating of business processes
  such as system operation, equipment maintenance,
  billing customer service, finance accounting,
  human resource and procurement management, etc.
• Main systems included operation management
  system (OMS), Distribution management system
  (DMS), AM/FM/GIS, Plant maintenance system and
  Customer Information System (CIS/CRM), ERP system
  and power market trading system, etc.
• Company management integration
• It is presented as the integration of corporate
  management applications. It covers the
  information sharing, integrating of procedures
  and applications on business processing level as
  well as on analysis decision making level.
• Main systems corporate-wide integrated data
  warehouse, application integration platform,
  cross business processing applications and
  decision-making support system, etc..

Status quo in 2005 (I)

• Leading local electric power company in China
  well-performed in power system operation,
  customer service and turnovers, etc..
• Have a high level on infrastructure construction
  and operation management
• substation automation system and EMS/SCADA is
  widely used
• Core business process systems like ERP, PMS, CIS,
  EMS etc. have been implemented and used for
  years. The ERP system can support major
  management processes in FI/CO,PS,PM,MM,HR which
  based on SAP R/3 platform.

CIS/CRM
ERP
PMS (AM/FM/GIS)
EMS/ SCADA
20
Status quo in 2005(II)

• Advanced application of power system analysis and
  controlling needs deep exploitation.
• The distribution automation systems and customer
  side digital facilities are still at the early
  stage and are relatively small-scaled
• Complicated business application and newly
  explored fields, such as business intelligence
  and field force enhancement, generate new demands
  on IT systems.
• Cross department and full value chain procedure
  supporting capability is deficient.
