Calculation of Steady MVA fed into Dead Short Circuit
Given Data:
- Busbar Reactor: 5 MVA, 8% Reactance
- Busbar A: Two Generators, each of 10 MVA, 10% Reactance
- Busbar B: Two Generators, each of 8 MVA, 12% Reactance
Step 1: Calculation of Total MVA at Busbar A
- Total MVA at Busbar A = 10 MVA + 10 MVA = 20 MVA
Step 2: Calculation of Total MVA at Busbar B
- Total MVA at Busbar B = 8 MVA + 8 MVA = 16 MVA
Step 3: Calculation of Total MVA at Busbar AB
- Total MVA at Busbar AB = Total MVA at Busbar A + Total MVA at Busbar B
- Total MVA at Busbar AB = 20 MVA + 16 MVA = 36 MVA
Step 4: Calculation of Short Circuit MVA
- Short Circuit MVA = Total MVA at Busbar AB - Busbar Reactor MVA
- Short Circuit MVA = 36 MVA - 5 MVA = 31 MVA
Step 5: Calculation of Steady MVA fed into Dead Short Circuit
- Steady MVA fed into Dead Short Circuit = Short Circuit MVA / Number of Generators
- Steady MVA fed into Dead Short Circuit = 31 MVA / 4 = 7.75 MVA
Explanation:
- The given data includes the details of generators and busbar reactors connected in a power system.
- The steady MVA fed into a dead short circuit between all phases on busbar section B needs to be calculated.
- The calculation involves finding the total MVA at busbar A and B, and then adding them to get the total MVA at busbar AB.
- The busbar reactor MVA is then subtracted from the total MVA at busbar AB to get the short circuit MVA.
- Finally, the steady MVA fed into the dead short circuit is calculated by dividing the short circuit MVA by the number of generators.
- The answer obtained is 7.75 MVA.
