Detailed information on driver testing for EPV-60KVA photovoltaic inverter aging testing system:
A photovoltaic system is an energy system that directly converts solar energy into electrical energy. When sunlight shines on solar cells (modules), it can generate direct current, which is collected and converted into alternating current power by photovoltaic inverters.
Photovoltaic inverters not only convert direct current into alternating current, but are also a key component of photovoltaic systems. There are currently two main types of photovoltaic systems: grid connected and standalone. Grid connected systems are usually installed in existing buildings to provide electricity directly into the grid; Independent inverters directly provide power and are typically used in situations where the power grid cannot provide it.
The solution for the automatic testing system of photovoltaic inverters includes:
Automatic aging assembly line+programmable DC power supply+digital analyzer+grid feedback+measurement and control system
Programmable DC power supply: It replaces the DC output of solar panels and generally provides a unique function called the simulation of the I-V curve of solar panels, which is used for performance evaluation testing of maximum power tracking (MPPT) for photovoltaic inverters.
Digital power analyzer/power meter: measures parameters of photovoltaic inverter output, such as voltage, current, power, power factor, harmonic components of each order, and total harmonic distortion.
Programmable AC power supply: Simulate various voltage and frequency changes in the power grid. If the AC source used cannot absorb current (energy), an external resistor is usually added.
Programmable AC/DC electronic load: It can directly load and test the voltage output characteristics of independent photovoltaic inverters.
The automatic testing system for photovoltaic inverters developed by integrating hardware instruments and a flexible control software platform is not only suitable for research and development, project verification, and regulatory testing, but also for large-scale production testing.
Introduction to the Edson Photovoltaic Inverter Automation Testing System:
Automated testing system for photovoltaic invertersAll rack mounted devices are placed in a 19 inch cabinet, and the power transmission and signal lines between the devices are properly wired. Most of them are hidden in the cabinet
The upper computer software automatically records the result data of each test item and summarizes and evaluates it
The photovoltaic cell simulator with communication interface, AC power analyzer, load and other equipment are all controlled by the upper computer. During the testing process, all tests can be completed with just one button. Test items can also be independently selected
It can ensure the consistency of each experimental process and thus guarantee the correctness of each experiment
During the testing process of the intelligent error correction function, any abnormal errors can be prompted
