Name of Project: Reconstruction of 110 kV relay protection in main step-down substation GPP-2 and opposite main step-down substations in LUKOIL Neftohim Burgas AD
   
Contractor: LUKOIL Neftohim Burgas AD
   
Description:

Project concerns reconstruction of 110 kV relay protection of two outgoing feeders from GPP-2 and opposite main step-down substations on the territory of the refinery LUKOIL Neftohim Burgas AD. Order includes further reconstruction of relay panels and control panels; design of new fiber optic connections to provide operation of the relay protections; substitution of oil-insulated measuring transformers at 110 kV outgoing feeders and coupler breaker with new SF6 measuring transformers.

   
Lead in exploitation: 11.2015
   
Finished Activities:
  1. Delivery and installation of steel structures to tables for measuring transformers;
  2. Delivery of 110 kV current transformers;
  3. Delivery of control cables and electrical equipment;
  4. Primary commutation: substitution of 110 kV oil-insulated measuring transformers with SF6 measuring transformers;
  5. Secondary commutation: reconstruction of relay panels and control panels by dismantle of existing equipment, laying and connection of control cables, and commissioning;
  6. Design and installation of fiber-optic connections for relay protections between GPP-2 and opposite main step-down substations;
  7. Calculation and elaboration of updated relay cards of the reconstructed relay protections.
