132 kV Substation By-pass – Falconara (AN)

BY-PASS OF 132 kV SUBSTATION – FALCONARA POWER PLANT (AN)

The project consisted in modifying the substation configuration by introducing a by-pass, enabling maintenance activities on the 132 kV substation (SSE) while maintaining operation.

The new high-voltage circuit breaker (ABB PASS) is connected on the incoming side to a cable line derived from the utility delivery point. On the outgoing side, the breaker feeds Transformer 2 (HV/MV), thus allowing maintenance with continuity of service.

The designed works included:

• Construction of reinforced-concrete structures;
• Installation of cable trenches/ducts inside the substation;
• Laying of HV cables from the delivery point to the breaker and from the breaker to the transformer intake;
• Installation of SF₆-insulated high-voltage breaker;
• Upgrading of the earthing system;
• Implementation of breaker control and protection systems.
