REFITTING STRATEGY FOR ROMANIAN POWER SYSTEM SUBSTATIONS
National Power Grid Company TRANSELECTRICA S.A. – ROMANIA
• Joint-Stock, 100% state-owned company• Operating according to Transmission and System Operator
Licenses and Transmission Grid Code • Founded further to Government Decision 627/2000 by
splitting former National Electricity Company (CONEL) into 4 separate legal entities
• 76 substations (voltage levels of 750kV, 400kV, 220kV and 110kV)

REFITTING STRATEGY FOR ROMANIAN POWER SYSTEM SUBSTATIONS
• MissionMission: – granting third party regulated access to Transmission
Power Grid– safe and cost-effective operation within an
encreasing competitive market economy
• Target:Target:- hub of electricity transmission in S-E Europe- interconnection to UCTE of Romanian Power System- transboundary electricity connections on the regional
market

• ‘turn-key project’• harmonising the Romanian norms and standards to the
suppliers’• legislation and equipment solutions • unity of technical solutions of a project• simplifying of the substation one-line diagram• finding and applying proper financing schemes

CRITERIA FOR SUBSTATION REFITTING HIERARCHY – CRITERIA FOR SUBSTATION REFITTING HIERARCHY – BASE OF RELIABILITY & IMPORTANCE METHODBASE OF RELIABILITY & IMPORTANCE METHOD
• The physical wear and the obsolescence of the technological electric installations that determine their technical condition
• The importance of the substations for the safe operation of the NPS
• The electricity transmitted yearly through the substations
• The economic-financial criteria
• Synchronous and asynchronous interconnection to the neighbouring electric power systems

REFITTING STRATEGY FOR ROMANIAN POWER SYSTEM SUBSTATIONS
CONCLUSIONSCONCLUSIONS
The realistic approach to the refitting projects of the substations in the ETG is based on a stable and modern strategy that:
• is conceptually structured in technical terms by means of advanced equipping solutions and the control of the electrical technological process at current world level
• is based on multi-criteria methods determining the sequence of refitting projects start up
• uses the global solution of “turnkey project”• provides an efficient project management carried on by the Project
managers• monitors the project development at different competence levels
using a specialized software• uses experience gained by already refitted substations in Romania
