6 FAQs about [What is the resonance principle of photovoltaic bracket]

What is the resonance mechanism of photovoltaic grid-connected system?

The resonance mechanism of photovoltaic grid-connected system is analyzed based on frequency domain analysis method. The notch filter is added into the active damping control method, and the active damping of the system is enhanced by using the notch characteristics.

How many resonance peaks are there in a photovoltaic grid-connected system?

1. There are usually two resonance peaks in photovoltaic grid-connected system, one of which is the natural resonance peak produced by LCL filter. The other is the coupling resonance peak formed by the parallel connection of multiple inverters and the impedance coupling of the power grid.

How to suppress resonance problem of photovoltaic grid-connected system?

In order to effectively suppress the resonance problem of photovoltaic grid-connected system, an optimization method of active damping resonance suppression is proposed by combining active damping notch control method and active damper method.

What is photovoltaic (PV) effect?

How to suppress coupling resonance when multiple inverters are connected?

Neither passive damping method nor active damping method can suppress the coupling resonance when multiple inverters are connected to the grid. The global resonance suppression method can effectively suppress the coupling resonance, but it has poor effect on the self-resonance suppression of inverter system.

How notch module is used in photovoltaic grid-connected system?

The notch module is introduced to expand the resonance damping area and increase the active damping of the system. At the same time, in order to suppress the coupling resonance of photovoltaic grid-connected system, an active damper is connected in parallel at the common bus, and virtual impedance is introduced to increase the system damping. 3.
