6 FAQs about [Huawei photovoltaic inverter lightning strike experiment]

Does a PV plant withstand a lightning strike?

The withstand voltage is generally linearly proportional to the number of bypass diodes connected in series. This paper investigated the transient behaviors of a PV plant during a lightning strike to the transmission line nearby. With the PEEC method, lightning-induced voltages in the PV system were simulated.

What is lightning induced voltage in a photovoltaic system?

Simulation of surges in a photovoltaic system Lightning induced voltages in DC cables is one of the critical issues in lightning protection of PV systems. This voltage may damage the inverter connected to the DC cable. The induced voltage on the PV panel could damage bypass diodes connected to the panel as well.

What causes system failures in PV plant during a lightning strike?

System failures in the PV plant during a lightning strike may be caused by the failure of PV inverters, breakdown of bypass diodes, arcing between PV frame and wires, and others. A power inverter plays a vital role in energy conversion in the PV system. It transforms the DC power generated by the PV modules into three-phase AC power.

How effective is lightning protection for PV systems?

The recommendations on the design of effective lightning protection for the PV systems are summarized as follows: The PV plant could suffer from serious lightning damages when a nearby transmission line is struck by lightning.

Are PV systems vulnerable to lightning?

Similar to other power systems [ , , , , ], PV systems are vulnerable to lightning because they are always installed in unsheltered open areas. Recent studies on lightning protection of PV systems have drawn much attentions [ 9 ].

Do lightning-induced voltages cause damage to PV systems?

With the PEEC method, lightning-induced voltages in the PV system were simulated. Significant overvoltages were observed and could cause damages to the PV systems, if protection measures were not provided appropriately. Simulation results were generally consistent with the field observation reported in the literature in some cases.
