Photovoltaic power generation is an efficient use of solar energy. In this article, the different types of solar transformer, including step-up transformers, step-down transformers, distribution transformers, substations, pad mounted and grounding, dry-type transformers, etc., which are mainly used in solar power plants are explained in detail.
Accordingly, load on solar inverter transformers also varies. Most of the time they operate at part load only. Hence, judicious selection of design parameters not only reduces the initial cost of transformer, they also help in optimizing the life cycle cost. Solar projects have very stringent project timelines.
Inverter Transformers are one of the most critical components in solar PV plants and are deployed in large numbers in large solar PV plants. Power output from PV Solar plant is inherently intermittent depending on available solar irradiance. Accordingly, load on solar inverter transformers also varies.
The operating conditions of the transformer connected to the inverter are particularly unknown for each solar power plant; thus, the transformer will be subject to a particular harmonic content, which is defined by the inverter of the solar power plant.
Renewable transformers also have different voltages than the standard industrial voltages you might have seen. 800, 630, and 600 are all common voltages used with solar arrays. 800V is more common with European inverter manufacturers; 630V is usually found in larger solar arrays; and 600V is the most common voltage for solar inverters.
To step up the output voltage of the inverter to such levels, a transformer is employed at its output. This facilitates further interconnections within the PV system before supplying power to the grid. The paper sets out various parameters associated with such transformers and the key performance indicators to be considered.
