Peak Feeder Load: A Case Study

Scenario 2: Wind Turbine-ON, Peak Feeder Load

For this scenario, the impact of introducing the six wind generators on the voltage profile and power flow of the study system is analyzed. Each of the six wind generators is providing 55kW at a power factor of 0.75. Taking into account the commitment of the neighborhood capacitor banks that bolster the generator field, the coming about comparable power factor is 0.89. Two of the three diesel generators are in performance. Every diesel generator is giving 0.5 MW, and is controlling its terminal voltage at 1.0 pu.

Figures 6 and 7 demonstrate that the system encounters a low voltage issue at a vast part of the network. This low-voltage circumstance can be effortlessly clarified by the way that the reactive power utilization of the wind generators, provided by the remote diesel generators, produces over the top voltage drop in the feeders.

A few conceivable answers to the low-voltage issue of the system when the wind generators are generating maximum power over a peak feeder load condition can be taken into account:

a) Increasing the terminal voltage of the diesel generators to 1.05 pu.

b) Adding capacitor banks at the wind generators' Bus.

c) Using doubly fed induction generators equipped for

One wind turbine is on, genrating 55kW at 0.75 power factor. In the interim, just a single of the three diesel generators has been in operation. This diesel generator supplies 285kW (30% of its rated capacity) and is controlling its terminal voltage at 1.0pu. The simulation aftereffects of the feeders' voltage profile under these conditions are appeared in Figure 13. Figure 13 demonstrates that the insearting of one twist generator amid light load conditions does not cause voltage
