INTRODUCTION

• Demand on electricity in Central Region of Saudi
  Arabia has increased dramatically in the last 3
  years ago ( Due to 9/11 Incident)???
• SEC wants to determine the optimum power will be
  transmitted to Central Region at the most optimum
  cost.
• The original proposal was to import 1800MW to
  Central From West via 1200KM High Voltage A/C
  Transmission Line.

OBJECTIVE

• To study and compare the original proposal with
  other alternatives and choose the most suitable
  system using V.E. techniques.

6
INFORMATION PHASE

• Provide save and reliable electricity
• Satisfy customer needs
• The material to be in-kingdom
• Low operational and maintenance cost

7
INFORMATION PHASE

• Supply Energy
• What must it do?
• Verb Noun
• Meet Increase in
  demand
• Ensure Reliability
• Enhance Stability

10
CREATIVE PHASE

• Generate Ideas
• Install 1200KM/380KV HVAC Transmission Line.
• Build new Generation Plant.
• Install 1200KM/500KV HVDC Transmission Line.
• Co-generation agreements
• Buy energy from private generation companies.

• Life Cycle Cost
• In Modern HVDC systems Normal Routine
  Maintenance can be done one week/2years.
  Moreover, HVDC systems require a few skilled
  staff to do the job. In terms of thermal rating
  HVDC systems can live long time. In contrast,
  HVAC needs lots of maintenance work and staffs
  i.e. lines and insulators wash, insulation test
  and patrolling. losses, tripping and short
  circuits can harm the HVAC aging . So, the
  maintenance cost for HVDC is less and the Return
  On Investment is guaranteed.

VALUE STUDY SUMMARY

• The HVDC has the following advantages
• Ensure very low environmental impact reduce
  construction time.
• Economically transmits large amount of power over
  long distances.
• Ensure minimum losses.
• Maintenance requirements are low.
• Flexibility of operation and control.
• Return on Investment is very high.

18
PRESENTATION PHASE

• V.E. study to be presented to the executive
  management to show the recommended alternative.

19
IMPLEMENTATION PHASE

• How should it be implemented?
• The proposed method will be award to GES
  contractor to prepare the drawings and the
  estimate.
• What should be changed and in what sequence?
• HVDC components to be installed in the
  transmitter and receiver end while construction
  the line.
• Who should do it?
• Qualified contractor who did similar projects
  before.

20
AUDIT PHASE

• Management should assign team to assure the
  desired results have been attained, properly
  documented and reported.
