Five years ahead it will be time to retire the Sanders69 power plant from the Metropolis power system. Because of enviromental reasons, it is impossible to build new generation in the dowtown area. As a planning engineer team for the local utility, Metropolis Light and Power (MLP), your job is to make recommendations on the construction of new lines and upgrade existing 69kV substation to accommodate 138kV as well; your purpose is to ensure that the transmission system in the MLP system is adequate for any base case or first contingency loading situation, when the Sanders69 power plant is no longer in service. Design Procedure 1. Load DesignCase2 into PowerWorld Simulator which contains the system dispatch without the Sanders69 generator. Perform an initial power flow solution to determine the initial system operating point. From this solution you should find that all the line flows and bus voltaje magnitudes are within their limits. Remember that all line MVA flows must be at or below 100% of their limit values, and all voltajes must be between 0.95 and 1.05 per unit. 2. Repeat the above analysis considering the impact of any single transmission line or transformer outage. This is known as N-1 contingency analysis. Without the Sanders69 generation this system is insecure for several contingencies – the analysisi finished with 13 violations, including at least one that has nothing to do with the power plant retirement (but it still needs to be fixed). Remember that all line MVA flows must be at or below 100% of their limit values, and all voltajes must be between 0.90 and 1.10 per unit. slack Metropolis Light and Power Design Case 2 SLACK345 SLACK138 RAY345 RAY138 RAY69 FERNA69 DEMAR69 SANDERS69 SANDERS138 BOB138 BOB69 WOLEN69 SCOT69 DAVIS69 ZEB69 PETE69 HISKY69 TIM69 TIM138 TIM345 PAI69 GROSS69 HANNAH69 AMANDA69 HOMER69 LAUF69 MORO138 LAUF138 HIMAN69 PATTEN69 WEBER69 CAROL138 NICOL69 NICOL138 JO138 JO345 1,02 pu 1,01 pu 1,02 pu 1,03 pu 0,99 pu 0,98 pu 1,00 pu 0,99 pu 1,00 pu 1,01 pu 0,98 pu 0,99 pu 0,99 pu 1,01 pu 1,01 pu 1,02 pu 1,00 pu 1,00 pu 1,02 pu 1,01 pu 1,01 pu 1,01 pu 1,02 pu 1,00 pu 1,01 pu 1,01 pu 0,99 pu 1,00 pu 1,01 pu 1,01 pu 1,02 pu 1,02 pu 1,03 pu 1,02 pu LYNN138 1,02 pu 0,99 pu System Losses: 13,54 MW 336 MW 77 Mvar 20 MW 4 Mvar 23 MW 6 Mvar 100 MW 45 Mvar 74 MW 27 Mvar 12 MW 5 Mvar 150 MW 2 Mvar 56 MW 13 Mvar 15 MW 5 Mvar 14 MW 3 Mvar 38 MW 13 Mvar 23 MW 3 Mvar 58 MW 36 Mvar 36 MW 10 Mvar 10 MW 5 Mvar 22 MW 15 Mvar 60 MW 12 Mvar 20 MW 31 Mvar 23 MW 6 Mvar 33 MW 13 Mvar 16,0 Mvar 18 MW 5 Mvar 58 MW 40 Mvar 45 MW 12 Mvar 18,3 Mvar 27 MW 3 Mvar 14 MW 3 Mvar 23 MW 6 Mvar 28 MW 6 Mvar 8,1 Mvar 7,3 Mvar 12,3 Mvar 28,3 Mvar 7,3 Mvar 0,0 Mvar 0 MW 0 Mvar 20 MW 6 Mvar 150 MW 2 Mvar 17 MW 3 Mvar 16 MW -6 Mvar 14 MW 4 Mvar
