Photovoltaic panel transformer radiation

How a PV plant affects transformer performance?

A PV plant has various impacts on performance parameters of transformers. The working of on-load tap changer is also affected by the presence of PV. The main cause behind the altered performance of transformer in the presence of solar panel is its associated inverters that are used to supply linear loads.

Does photovoltaic penetration affect transformer performance?

Due to high penetration of renewable energy, the installed transformers have observational impact on their insulation, leading to degradation of transformer life. This paper presents a case study of Gujarat solar power plant to find the impact of photovoltaic (PV) penetration on transformer performance in the time span of 1 year.

How a transformer affects the performance of a solar plant?

From the analysis of four 2.5 MVA transformers in the solar plant in the time span of 1 year, it has been found that the PV has huge impact on the transformer performance, which is influenced by the load on transformer, the level of PV penetration and the rating of transformers.

Do solar panels affect transformer performance?

But the harmonics effects caused by the solar panel have negative impact on performance of transformers. Reversal of power is also one of the negative impacts of PV penetration. Furthermore, the frequency of working of OLTC increased by 45% due to solar integration, which may increase the risk of failure of transformers.

Does a solar panel affect a distribution transformer?

Thus, from the literature survey, we can conclude that the solar panel has considerable impact on performance of the distribution transformer, and that further study is needed to find other impacts on the transformer, so that the diagnosis of the transformer can be done at the earlier stage and the transformer saved from any decaying process.

How does PV penetration affect the reliability of Transformers?

Reversal of power is also one of the negative impacts of PV penetration. Furthermore, the frequency of working of OLTC increased by 45% due to solar integration, which may increase the risk of failure of transformers. Overall, the reliability of transformer will increase due to PV penetration if we can minimize negative effects of PV integration.
