The transformer is the most important part of any transmission system, so the transformer must be in the correct working condition to provide uninterrupted power supply at various locations around the substation. Renewable energy is rapidly replacing traditional energy all over the world. The key to solar transformers is to understand the variables in each system.
The transformer needs to be customized for use with each specific system. Obtain the "boost" or "buck" energy from the energy source. There are many types of solar transformers, including power distribution, power station, substation, cushion installation, and grounding. All solar transformers have special requirements that affect cost.
The size limit of the inverter also limits the size of the photovoltaic system. It is very difficult to increase the size by adding more solar inverters in a transformer box. With the required box size and the cable to convert DC to AC, things get complicated.
Renewable energy is rapidly replacing traditional energy all over the world. Due to the high penetration of renewable energy, the installed transformer has an observable effect on its insulation, which leads to a reduction in the life of the transformer(box type transformer stations: uses of transformer).
The lower harmonic curve is because there are no generators, switches, and protection controls on the wind turbine. Solar transformers do need to be boosted. However, the solar inverter can smoothly transform the DC input of the PV array into the AC voltage of the transformer without the overvoltage of the no-load circuit. Since the solar transformer operates at a stable voltage and the rated voltage is controlled by the inverter, the voltage and load fluctuations are significantly lower than that of a wind turbine. The operation of the photovoltaic system is also close to its rated load.
In the presence of solar panels, the main reason for changes in transformer performance is related to the inverters used to provide linear loads. Due to the voltage and current harmonics, the windings and iron cores of the transformer will have a higher temperature rise, resulting in additional losses. This article introduces the cumulative effect of solar power plants on transformer operation in one year and discovers the negative and positive effects on transformer parameters.
