Abstract
This paper presents performance analysis of surge protection system for floating solar photovoltaic (PV) installations. The prototype of PV system of 1 kW was designed and implemented in two sets for practical testing. The first set was tested in a laboratory environment for isolated system evaluation, while the second set was installed on floating platforms in a water reservoir for integrated system testing. The proposed surge protection system was designed to provide overvoltage suppression for both direct current (DC) and alternating current (AC) circuits. To validate its effectiveness, a combination wave generator was designed and constructed in accordance with IEC 61000-4-5 standards, enabling standardized surge tests in low-voltage electrical networks. The experimental results from both laboratory and field environments confirm that the designed protection scheme effectively limits overvoltage magnitudes below the withstand levels of cables, connectors, and insulators employed in floating solar PV systems. The findings demonstrate that the performance of the protection system is technically feasible, reliable, and well-suited for practical deployment under operating conditions.
