What are the gains for TSOs to install Ampacimon Dynamic Line Rating set?
The existing national grids are being used up to their limits. To rapidly manage local constraints of sag and conductor temperature, many TSOs consider using Dynamic Line Rating (DLR), also called Real Time Thermal Rating (RTTR), instead of seasonal static ratings. Ampacimon, thanks to its reliability, easy installation and straightforward commissioning, is the ideal solution for DLR with no penalty on safety.
Real Time Sag Monitoring allows you to be alarmed when the sag approaches the set limit and to have a reliable measure of the actual conductor temperature. This enhances the confidence in your network operation and control and provides evidence for potential audits regarding clearance violation.
Real Time Monitoring may allow you to avoid blackout by cascade tripping due to apparent overloads. Alerts are only generated when the real limits are reached and this can be used to program the relays.
Ampacimon allows you to increase the capacity of your critical lines significantly, most of the time by at least 30 % with respect to the seasonal static limits. This is particularly relevant for the integration of renewable energy plants in areas with limited transport capacity (as is often the case). Ampacimon enables you to significantly reduce the need to curtail the connected wind turbines or other generation sources.
Ampacimon’s intraday forecasted (4 hours) ampacity allows you to manage your congestion issues in a more efficient way, reducing the number of times you need to take corrective and expensive actions like starting-up emergency generation and/or redispatching.
Day ahead forecasted ampacity (under development & field tests in 2011) will open-up further significant usage domains at a very reasonable cost. Such as relieving some of the congestion on the much-used inter-connectors between networks, thus improving the operation of inter-connected energy markets, generating additional value for the energy market as a whole.
DLR (Dynamic Line Rating) in conjunction with WAMS (Wide Area Measurement Systems) and PST (Phase Shift Transformers) allows improving the flexibility and stability of a large region of the global grid. This combined setup will be trialed during the EU funded TWENTIES project.
The detailed historical data about your lines that Ampacimon collects will help you to better understand the behaviour of your lines and use this knowledge to create better short and long-term plans for the management of your network.
