Notas do Editor
- MTBF = Mean Time Between Failure MTTR = Mean Time To Repair, Note: The PASS concept considers the time needed for replacing the pole or of the module instead of repairing it on site
- The example is referred to a double busbar bay made with conventional component and with PASS M0 DBB
- In the present case only the line and transformer bay have been replaced by PASS M0. The coupling, the busbar, the voltage transformer and the cable bushing belong to the existing substation.
- The module can be provided with disconnectors only
- Unavailability means the outage time for the bay due to maintenance and repair
- EXAMPLE REFERRED TO A SUBSTATION WITH RIGID H CONFIGURATION: COST OF THE COMPONENTS ONLY
- LIFE CYCLE COST MEANS THE TOTAL COST OF OWNERSHIP AND INCLUDES THE FOLLOWING ITEMS : - INITIAL COST FOR BUILD UP THE SUBSTATION (C&P, ENGINEERING, COMPONENTS, CIVIL WORKS, ETC) - OPERATION & MAINTENANCE COSTS, CONSIDERING AN AVERAGE S/S LIFE OF 20 YEARS - REPAIRING COST AS ABOVE
- THE EXAMPLE IS APPLICABLE TO THIS SPECIFIC SUBSTATION; IT WILL BE PRESENTED AT THE NEXT CIGRE' 2000. IT IS REFERRED TO A PROPOSED S/S SOLUTION, NOT SIMPLY LIMITED TO A SALE OF COMPONENTS: NOTE: - CUSTOMER NEEDS means the customer's requirements listed according to the customer priorities: VERY IMPORTANT: the customer core business is to sell energy. - CUSTOMER SOLUTION means the solution proposed by the customer, based on its experience.
- ABB SOLUTION: - SINGLE BUSBAR SYSTEM WITH PASS M0 ASSURING THE SAME FUNCTIONALITIES; - IMPORTANT: the feeders are connected according to the need of maximum availability on S/S B; note that S/S B can experience an outage only if the bay B1 and B or both couplers experience an outage contemporary.
- IInd ABB SOLUTION The proposed solution makes use of PASS M0 double circuit breaker. As before, the solution assures the same functionalities and a further space reduction. Also in the present case, the maximum availability results on S/S B
- COMPARISON OF FEEDED SUBSTATIONS UNAVAILABILITY DUE TO CONVENTIONAL AND PASS M0 PROPOSED SOLUTIONS: - the comparison between conventional and PASS M0 solution shows a higher S/S (A, B, C) unavailability if feeded by the conventional solution (CONV_DBB, double busbar system) in respect to PASS M0 solutions (single busbar PASS_SBB and double circuit breaker PASS_DCB).
- Life Cycle Cost comparison of the customer S/S solution (CONV_DBB), and ABB proposed solutions with PASS ( PASS_SBB and PASS_DCB). Life Cycle Cost means the total cost of ownership and includes the following items : - initial cost for build up the substation (c&p, engineering, components, civil works, etc) - operation & maintenance costs, considering an average s/s life of 20 years - repairing cost and cost of power and energy interruption (1 USD/kW and 0.2 USD/kWh)
