Terranova TSG

RETISMARTGRID is an innovative Network Management Software offering an integrated and smart approach to the management of distribution network infrastructures for gas, electricity and water utilities.  
The platform offers functionalities addressing following operating processes:

•    Objects Representation  
•    Diagnostic
•    Remote Command/Control
•    Network Profiling 
•    Simulation 
•    Network Automatic Setting

RETISMARTGRID provides specific tools to optimize the usage and the maintenance of the Company’s assets, data monitoring and tele-reading, as well as remote control of the network. 

The user has an at-glance access to the whole network, thanks to the representation of every object on the cartographic layer. To receive all cartographic information related to network elements and enable their visual representation, RETISMARTGRID integrates seamlessly with the Geographic Information System (GIS). 

RETISMARTGRID provides an integrated and innovative approach to distribution network management with a view to increasing operational efficiency and safety.  The platform aims at represent the devices on site and their diagnostic status, analyze the data and generating alarms, in order to optimize the management of the asset and the work of the operators on site. 

Data and Controls are completely compartmentalized thus to ensure highest level of security in operation and management both. Terranova allocates extensive R&D resources to focus on this aspect, leveraging the cooperation with the Computer Science Department of the University of Pisa. 

RETISMARTGRID allows the Distributor to “schedule” changes that will be carried out directly by the network. Profiling the distribution system allows the DSO to better manage its assets, their performances, as well as balance the network and reduce energy waste.

Achievement of business continuity is one of the main concerns of network infrastructure management in public utilities.  RETISMARTGRID’s features envisage software installation also into Virtualized Environments according to redundancy criteria.

The diagnostic functions allow to improve both safety and service quality while the integration with Terranova’s TWFA software provides additional support for task area operations for assets maintenance as well as maintenance planning and scheduling. 


Increasing or decreasing the output pressure of a regulator is enough to decrease or to reduce the movement strength/intensity.
The increase or the reduction of the movement could be obtained by increasing or reducing the gas or the air pressure (motorization pressure) injected into the spring’s chamber.

The calibration spring must be set in order to obtain the minimum pressure value compatible with the system.

Changing the set point pressure of a regulator, without the intervention of an operator, is useful in all the cases in which the pressure in the grid is very variable during the day because the variable load conditions to ensure an appropriate supply to all the network users.

The aim to reduce the gas leakages of a grid can be obtained by keeping the pressure to a minimum value when it is possible.

The system is able to drive up to 10 lines of regulation, maintaining the specified intervention ΔP between lines. The “pressure profiling“ function carries out an automatic control to change the outlet pressure to a value specific to the period of the day. It is possible to configure up to 7 different pressure set points for each day of the week.

The ECU module stores a weekly active schedule and a further future schedule. If flow measurement is available (computed with indirect method or directly detected from a meter or corrector), the “Pressure compensation “ function can be activated as an alternative to “Pressure profiling “. This function allows to automatically correlate the inlet pressure with the instant flow. The modulation accuracy is better than 1% of the nominal full range pressure value.
