6 FAQs about [Photovoltaic support adjustment device]

Why is reactive power adjustment necessary in photovoltaic power stations?

dely used in photovoltaic power stations. However, because the output power of PV systems will be affected by factors such as weather and temperature, resulting in changes in the active power output to the grid connection point, the reactive power adjustment of the system is required to stabiliz

What is the tilt angle of a photovoltaic support system?

The comparison of the mode shapes of tracking photovoltaic support system measured by the FM and simulated by the FE (tilt angle = 30°). The modal test results indicated that the natural vibration frequencies of the structure remains relatively constant as the tilt angle increases.

How stiff is a tracking photovoltaic support system?

Because the support structure of the tracking photovoltaic support system has a long extension length and the components are D-shaped hollow steel pipes, the overall stiffness of the structure was found to be low, and the first three natural frequencies were between 2.934 and 4.921.

Can a tracking photovoltaic support system reduce wind-induced vibration?

Finite element analysis also showed a slight increase in natural frequencies with increasing inclination angle, which was in good agreement. This suggests that the design of the tracking photovoltaic support system can be optimized to reduce the impact of wind-induced vibration on the tracking photovoltaic support system.

What are the dynamic characteristics of photovoltaic support systems?

Key findings are as follows. Dynamic characteristics of tracking photovoltaic support systems obtained through field modal testing at various inclinations, revealing three torsional modes within the 2.9–5.0 Hz frequency range, accompanied by relatively small modal damping ratios ranging from 1.07 % to 2.99 %.

Does inclination increase the vibration frequency of a tracking photovoltaic support system?

What can be shown by the modal test results and finite element simulations of the tracking photovoltaic power generation bracket tracking photovoltaic support system was that the natural vibration frequency of the structure has a slight increase as the inclination angle increases.
