Product Description:
Photovoltaic grid connected power generation system belongs to distributed power supply system. When the power supply is interrupted due to electrical failure, misoperation or natural factors, each photovoltaic grid connected power generation system is still running,
And the connection with the local load is in an independent operation state, which is called islａnd effect. Considering power safety and power quality, isolated islａnd is not allowed. So, photovoltaic
The grid connected power generation system shall have the ability to detect the islａnd state and stop the grid connected operation quickly and effectively.
In order to meet the anti islanding test and detection requirements of grid connected inverter. Wstf-87300 series anti islanding resonant load can simulate various RLC AC loads and various working environments of inverter
Measuring the actual output power and load capacity of the inverter can detect and debug the resonance point of the photovoltaic inverter. The host has built-in pure resistive load and inductive load, and the power input adopts segmented combined control,
Various power inputs can be combined arbitrarily.
The wstf-87300 series anti islanding resonance load we provide can accurately detect the output power and load capacity of various generator sets.
