Case
Electricity distribution - Applications maintenance project
Many of our projects address critical and strategic issues for our customers who, therefore, choose to not disclose their name”.
Environment
The client is a transmission system operator, responsible for the transmission of electricity. Electricity is transmitted over the high-voltage grid from electricity generators to the distribution system operators and large industrial consumers. This grid forms a key connection between several large electricity exporters across Europe.
In a project of reorganising its 11 regional centres and concentrate them into 3 new units, the client wanted to build a real-time dual-computer system composed of:
Front-ends in charge of the communication with the acquisition equipments
Host system performing the treatments of the data received from the front-ends
A man-machine interface which comprises all aspects of visualization of information by the operators and the management of the operator actions on the controlled grid.
Solution
Since the first installation in of the system 1996, Trasys ensures the complete maintenance of the system, including preventive, corrective and evolutionary maintenance, assistance 24x 7 and data base administration. The maintenance is covered by a SLA and associated penalties in case specific tasks are not performed properly or timely. For instance, the SLA guarantees a deadline of maximum 10 minutes after a call for starting the intervention. Another example is the 30 minutes deadline for implementing a solution of circumventing bugs blockers leading to the loss of conduct and monitoring network.
Benefits
By transferring the maintenance of the system to Trasys, the client can concentrate on core business activities – managing the electricity network- while the IT department can concentrate time and resources on critical applications. The values of the key performance indicators are examined every month, coupled with recommendations to ensure those values always keep the agreed intervals.
