Dynamic stability modified IEEE 3 generator 9 bus with 50 MW power injection of generator XY

Abstract

The existence of new power injection at a system will effect system stability that existed before, so stability analyze was needed to know the system conditioning before and after power injection, and performance system after disturbance, by observe rotor angle, frequency, and voltage. The result of dynamic system show that power injection of Gen XY can supply 0,021 pu at bus 1, 0,001 at bus 2, 0,001 at bus 3, 0,0261 pu at bus 4, 0,0366 pu at bus 5, 0,0186 pu at bus 6, 0,0101 pu at bus 7, 0,0083 pu at bus 8, 0,0061 pu at bus 9. When 3 phase fault during 1–2 second happened, the frequency and rotor angle increasing. When generator XY inject system with 50 MW, the modified IEEE 3 Generator 9 Bus become increase with frequency 60.27 Hz, voltage profile increasing, rotor angle decreased close to normal conditions.
