Background

Based on the relevant requirements of IEC62116 "Anti-islanding test method for inverters for photovoltaic well network systems", grid-connected inverter products must strictly undergo factory tests and type tests. Shiying Technology has developed an anti-islanding detection platform for the test requirements of anti-islanding protection tests, which can achieve high-precision type tests and scientific research tests, effectively implement product quality control, and comprehensively and efficiently implement product factory tests and inspections, avoid human detection errors, and meet the requirements of fully automatic detection.

Main functions of anti-islanding detection platform

1. Test function: It can achieve high-precision type tests and scientific research tests, effectively implement product quality control, and comprehensively and efficiently implement product factory tests and inspections.

2. Three-phase independent adjustment: The load can be controlled and adjusted in phases, and each phase resonance point can be accurately debugged under the condition of unbalanced three-phase voltage.

3. Resistor, inductor and capacitor: Built-in resistive load, inductive load, and capacitive load, with high precision and small temperature drift, can be intelligently allocated according to the standard, and can stably, quickly and automatically debug the base frequency to simulate various complex working conditions.

4. Harmonic analysis: The host has voltage harmonic detection function and current harmonic detection function, and can intuitively display the harmonic content in the form of a bar graph.

5. Intelligence: The fully automatic detection platform RLC prevents dead loads, comprehensively detects the performance of the inverter, and realizes quality factor and resonance point testing through software.

6. Protection function: Simulate the resonance of AC power equipment, and effectively and accurately detect the anti-islanding effect protection function of the well network inverter.
