6 FAQs about [Photovoltaic bracket Wang Ping]

Which wind-vibration coefficient should be used for flexible PV support structures?

Considering the safety of flexible PV support structures, it is reasonable to use the displacement wind-vibration coefficient rather than the load wind-vibration coefficient. For the flexible PV arrays with wind-resistant cables discussed in this study, a recommended range for the wind-vibration coefficient is 1.5 to 2.52.

What are the reinforcement strategies for flexible PV support structures?

This study proposes and evaluates several reinforcement strategies for flexible PV support structures. The baseline, unreinforced flexible PV support structure is designated as F. The first reinforcement strategy involves increasing the diameter of the prestressed cables to 17.8 mm and 21.6 mm, respectively.

Do wind-induced vibrations affect flexible PV support structures?

An analysis of the wind-induced vibration responses of the flexible PV support structures was conducted. The results indicated that the mid-span displacements and the axial forces in the wind-resistant cables are greater under wind-pressure conditions compared to wind-suction conditions.

Do flexible PV support structures amplify oscillations?

The research explores the critical wind speeds relative to varying spans and prestress levels within the system. Modal analysis reveals that the flexible PV support structures do not experience resonant frequencies that could amplify oscillations. The analysis also provides insights into the mode shapes of these structures.

How to reduce Lightning transient effects on PV system?

To reduce the lightning transient effects on the PV system, some protection measurements were proposed, including the grounding of the metal parts, providing external lightning protection such as the air termination rod, or using SPDs . The lightning effects on a large-scale PV plant with the existence of LPS was studied before [

How safe are flexible PV brackets under extreme operating conditions?

Safety Analysis under Extreme Operating Conditions For flexible PV brackets, the allowable deflection value adopted in current engineering practice is 1/100 of the span length .
