In recent years, the growing need for electric energy and the non-renewability of fossil fuels on one hand, and the increase in environmental pollution on the other, have driven researchers and investors in the energy sector to seek electric energy from renewable, clean, and reliable sources. Among renewable sources, solar energy stands out as one of the safest and most reliable methods for electricity supply, especially given the vast areas of the country with high solar radiation potential.
Transformers are crucial components in solar power plants for energy production and distribution. The DC voltage generated by photovoltaic cells is converted to AC voltage by inverters, which is then connected to the grid through these transformers.
Key Design Considerations for Solar Power Plant Transformers:

1. Step-Up Configurations:
Solar transformers can be configured as step-up transformers. The design must ensure long-term and stable performance to maintain efficiency and reliability.
2. Handling DC Components and Harmonics:
Due to their direct connection to solar inverters, these transformers are exposed to input voltage with DC components and high-order harmonics. These factors can damage the windings and limit transformer performance. Thus, the design must address these issues to ensure durability.
3. Insulation and Overvoltage Protection:
High-frequency overvoltages from power electronic elements in solar inverters require careful insulation design. Measures should be taken to prevent these overvoltages from transmitting between the primary and secondary windings.
4. Thermal Design:
The effects of harmonics, reactive loads, ambient temperature changes, and other factors must be considered in the thermal design to ensure the transformer operates efficiently under varying conditions.
