Final answer:
To ensure each generator in a multiple generator system shares the load, generators are synchronized, with load sharing controls used to adjust each generator's output according to real-time demand. Transformers then step up or down the voltage for transmission and distribution.
Step-by-step explanation:
To ensure that each generator shares the load in a multiple generator system, several methods are employed. These include having parallel connections between generators, implementing load sharing controls, and employing synchronization processes. Load sharing is crucial for the stability and efficiency of the power system.
Generators in a power system are synchronized so that their output voltage is in phase and at the same frequency. Synchronization ensures smooth operation and prevents the generators from working against each other. Once synchronized, load sharing controls adjust the output of each generator. The controls may be based on the real-time demand to achieve efficient distribution of the load.
It's also critical for transformers to function properly, stepping up or down the voltage for efficient transmission and distribution, as indicated in Figure 20.17. The use of transformers ensures that power is delivered to consumers at safe voltages. Moreover, the introduction of micro-inverters in alternative energy sources like solar panels ensures that power output is unified at higher voltages before being combined in parallel.
