Supervision and Control System
National Dispatching Center
Built during 2006. as integrated turn key project
- real-time supervision of major entry and exit points
98% of entry and 90% of exit flow
- remote flowrate/pressure control on important network nodes
- SIMONE real time model + leak detection
support for decision in real-time balancing activities

Plinacro – Transmission System Operator NOW
Technical conditions for operating transmission system
• stable flat flow rates on supply points
• 40% of transmission for households consumption - seasonal character
• no established full transmission nomination regime
• UGS flow rate set by TSO, based on actual state and partially known plans
Bussines enviroment for operating transmission system
• Plinacro - unbundled TSO, 100% state owned
• basic legal framework for opening gas market exist
• lower legal acts in preparation (market rules, network codes etc.)
• one shipper - one transmission contract
• no compettion for transmisson capacity acces
7
Plinacro – Transmission System Operator IN NEAR FUTURE
• transmission system extension – new border interconnections - transit
• real gas market opening - new market players – new shippers
• nondiscriminatory and transparent TPA
• nomination, allocation, balancing - required IT support
New IT infrastructure
• telereading system - all exit points daily metered and fiscal data acquired via GPRS
• Gas Transmission Management System
− contract management (interconnection, capacity booking)
− transmission nomination process
− allocation, balancing, reporting
− upgrade SIMONE instalation
evaluation of capacity requests and nominations
automated scenario preparation and result presentation

Focus on pipeline simulation (MS)
• Online system
– Installed functions
– Performance
• Offline simulations
• Customizations
• Benefits, experience, future

SIMONE online - functions
• State reconstruction
(PRSIM)
– SCADA data
– Manual entries (PRSIM_INC)
– Pig tracking
• Leak detection and
localization (LDSIM)
– Detection – jump of mass
correction signal for network
areas
– Localization – test & trial for
nodes/milepost within area
• Look-ahead simulation
(ZYSIM)
– Forecasted/scheduled flows
from UDW
– Manual entries (ZYSIM_INC)
• On-request simulation
– Save ZYSIM as…
– Data preparation from UDW
• Computational features
– Quality tracking, heat

SIMONE online - performance
• State reconstruction (PRSIM)
– Linepack always well captured – pressure readings…
– Influence of manually entered offtakes
• Mass correction
• Flow distribution within loops
• Look-ahead simulation (ZYSIM)
– Flow-flow simulation starting from last state
– Smoothness of concatenation with PRSIM

Leak detection & localization
• Feasibility study
– Leak caused by hole of equivalent diameter 30 mm is
detectable within area
– Localization to node/milepost not 100%
• Test case
– Filling new part of pipeline, flow measured but unknown to
real-time model
• False alarms
– Known areas – few measurements & manually entered
offtakes

Offline simulations
• 2 offline workplaces
• Usage
– System development
– Operation planning
– Capacity studies
• Highly transient behavior of Plinacro pipeline

• Online
– Supplies network balance
data for operators
– Brings “another” view on
readings
– Enables short-term what-if
analysis by expert
– Continuous extensions and
improvements
• Offline
– Useful for complex analysis
– Input data needed
Future
• Online
– More integration for operators
– Redundancy
• GTMS project
– Capacity calculations
– Nomination handling
– Easy access to data

Supervision and Control System
National Dispatching Center
Built during 2006. as integrated turn key project
- real-time supervision of major entry and exit points
98% of entry and 90% of exit flow
- remote flowrate/pressure control on important network nodes
- SIMONE real time model + leak detection
support for decision in real-time balancing activities

Plinacro – Transmission System Operator NOW
Technical conditions for operating transmission system
• stable flat flow rates on supply points
• 40% of transmission for households consumption - seasonal character
• no established full transmission nomination regime
• UGS flow rate set by TSO, based on actual state and partially known plans
Bussines enviroment for operating transmission system
• Plinacro - unbundled TSO, 100% state owned
• basic legal framework for opening gas market exist
• lower legal acts in preparation (market rules, network codes etc.)
• one shipper - one transmission contract
• no compettion for transmisson capacity acces
7
Plinacro – Transmission System Operator IN NEAR FUTURE
• transmission system extension – new border interconnections - transit
• real gas market opening - new market players – new shippers
• nondiscriminatory and transparent TPA
• nomination, allocation, balancing - required IT support
New IT infrastructure
• telereading system - all exit points daily metered and fiscal data acquired via GPRS
• Gas Transmission Management System
− contract management (interconnection, capacity booking)
− transmission nomination process
− allocation, balancing, reporting
− upgrade SIMONE instalation
evaluation of capacity requests and nominations
automated scenario preparation and result presentation

• Look-ahead simulation
(ZYSIM)
– Forecasted/scheduled flows
from UDW
– Manual entries (ZYSIM_INC)
• On-request simulation
– Save ZYSIM as…
– Data preparation from UDW
• Computational features
– Quality tracking, heat

Leak detection & localization
• Feasibility study
– Leak caused by hole of equivalent diameter 30 mm is
detectable within area
– Localization to node/milepost not 100%
• Test case
– Filling new part of pipeline, flow measured but unknown to
real-time model
• False alarms
– Known areas – few measurements & manually entered
offtakes

Offline simulations
• 2 offline workplaces
• Usage
– System development
– Operation planning
– Capacity studies
• Highly transient behavior of Plinacro pipeline
system
– Flat supplies vs. modulated consumptions
– Daily average static vs. Dynamic analysis

• Online
– Supplies network balance
data for operators
– Brings “another” view on
readings
– Enables short-term what-if
analysis by expert
– Continuous extensions and
improvements
• Offline
– Useful for complex analysis
– Input data needed
Future
• Online
– More integration for operators
– Redundancy
• GTMS project
– Capacity calculations
– Nomination handling
– Easy access to data

Plinacro – Transmission System Operator NOW
Technical conditions for operating transmission system
• stable flat flow rates on supply points
• 40% of transmission for households consumption - seasonal character
• no established full transmission nomination regime
• UGS flow rate set by TSO, based on actual state and partially known plans
Bussines enviroment for operating transmission system
• Plinacro - unbundled TSO, 100% state owned
• basic legal framework for opening gas market exist
• lower legal acts in preparation (market rules, network codes etc.)
• one shipper - one transmission contract
• no compettion for transmisson capacity acces
7
Plinacro – Transmission System Operator IN NEAR FUTURE
• transmission system extension – new border interconnections - transit
• real gas market opening - new market players – new shippers
• nondiscriminatory and transparent TPA
• nomination, allocation, balancing - required IT support

• Feasibility study
– Leak caused by hole of equivalent diameter 30 mm is
detectable within area
– Localization to node/milepost not 100%
• Test case
– Filling new part of pipeline, flow measured but unknown to
real-time model
• False alarms
– Known areas – few measurements & manually entered
offtakes

Leak detection & localization
• Feasibility study
– Leak caused by hole of equivalent diameter 30 mm is
detectable within area
– Localization to node/milepost not 100%
• Test case
– Filling new part of pipeline, flow measured but unknown to
real-time model
• False alarms
– Known areas – few measurements & manually entered
offtakes

Plinacro – Transmission System Operator NOW
Technical conditions for operating transmission system
• stable flat flow rates on supply points
• 40% of transmission for households consumption - seasonal character
• no established full transmission nomination regime
• UGS flow rate set by TSO, based on actual state and partially known plans
Bussines enviroment for operating transmission system
• Plinacro - unbundled TSO, 100% state owned
• basic legal framework for opening gas market exist
• lower legal acts in preparation (market rules, network codes etc.)
• one shipper - one transmission contract
• no compettion for transmisson capacity acces
7
Plinacro – Transmission System Operator IN NEAR FUTURE
• transmission system extension – new border interconnections - transit
• real gas market opening - new market players – new shippers
• nondiscriminatory and transparent TPA
• nomination, allocation, balancing - required IT support
New IT infrastructure
• telereading system - all exit points daily metered and fiscal data acquired via GPRS
• Gas Transmission Management System
− contract management (interconnection, capacity booking)
− transmission nomination process
− allocation, balancing, reporting
− upgrade SIMONE instalation
evaluation of capacity requests and nominations
automated scenario preparation and result presentation
