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. Function introduction: 1. The main loop consists of resistive network, perceptual network and capacitive network. 2. The combination can realize the adjustable power factor of ± 0.3 ~ 1. 3. RLC three-phase independent split phase control 4. Simulate the resonance of AC electrical equipment and effectively and accurately detect the anti islanding effect protection function of grid connected inverter. 5. Detect the working efficiency, maximum output power and load capacity of various inverters under full load operation. 6. Simulate various complex working environments and detect the comprehensive working performance of the inverter in various environments. 7. It is applied to the product acceptance and daily maintenance detection of grid connected inverters by users, comprehensively and scientifically detect the power supply capacity of various inverters, and accurately provide detection reports. Application fields: It is used in the fields of grid connected inverter delivery inspection, type test, production commissioning, scientific research and development, laboratory electrical test, identification and detection of authoritative institutions, etc. | ||||||
