Step-up transformer use to supply distribution stations from generating stations by H.V or E.H.V lines by three phase three wires system with almost constant power factor laging, near to unity and load to maximize efficiency. Step- down transformers are used at receiving end in distribution substation, to supply the load directly to industrial areas or to pole mounted distribution transformers supplying domestic customers at lower voltages. In all transformers there are two types of losses iron loss the constant loss, and copper loss depending on load and power factor, iron loss consists of hysteresis loss and eddy current loss ( Wi=Wh+We=Af+B(f)(f)) and cooper loss ( (I)(I)R) depending on current (l).
Loading in transform could be short time over loading, and the under load, the time life consuming could be utilized for over loading keeping life consuming in a day, the same or life consuming cost of a day the same. I developed the formula for “Microprocessor based online, Overload time limit computation and control depending on hot spot temperature with capacity addition “, could refer my papers ….
The effects of transformer loading on energy dispatch can be significant and can impact the overall efficiency and reliability of the power system. Here are some of the key effects:
1-Transformer Losses
2-Voltage Regulation
3-Thermal Considerations
4-Dispatch Optimization( for example, dispatch algorithms may take into account the transformer loading and losses to determine the optimal generation and transmission schedules, aiming to minimize overall system losses and maximize energy efficiency)
