Photovoltaic industry has ushered in a period of vigorous development. As the core equipment of photovoltaic power stations, the performance and reliability of photovoltaic inverters directly affect the overall efficiency of power stations and the stability of power grids. However, the complex and changeable power grid environment and strict industry standards have put forward higher requirements for photovoltaic inverter testing. With advanced technology and customization capabilities, the grid-feedback simulation power supply ANBGS provides professional and efficient solutions for global photovoltaic inverter testing, becoming a key force in promoting industrial upgrading.
Fitting the characteristics of the power grid and accurately simulating complex working conditions
The power grid environment in different regions is significantly different. In remote mountainous areas, the power grid lines are long, the losses are large, and the voltage fluctuates frequently; in industrial concentrated areas, the power grid harmonic interference and three-phase imbalance are prominent. Based on advanced power electronics technology and digital control technology, ANBGS can accurately simulate the complex working conditions unique to the power grid.
It can simulate extreme voltage and frequency changes such as ±30% rated voltage fluctuations and 2Hz frequency deviations, and can also superimpose 2-50 harmonics to accurately restore industrial scene harmonic interference. For example, when simulating a winter grid voltage drop scenario, ANBGS can complete the voltage drop simulation within 1ms, test the ride-through capability and protection performance of the photovoltaic inverter under low voltage, and ensure the stable operation of the inverter in various grid environments.
Meet stringent standards and ensure product compliance
The global photovoltaic industry is developing rapidly. In order to ensure that photovoltaic inverters meet the use requirements, relevant standards such as IEC62109-1, IEC61727, IEC62116, and IEEE1547 have been formulated worldwide to clearly define the electrical performance, grid adaptability, and protection functions of the inverter. ANBGS deeply adapts to these standards to provide an accurate basis for inverter testing.
In terms of electrical performance testing, ANBGS, in conjunction with a high-precision power analyzer, can accurately measure the inverter conversion efficiency, with an error control within ±0.2%, meeting the accuracy requirements of international standards for efficiency testing;
In the grid adaptability test, ANBGS supports continuous adjustment of the three-phase voltage imbalance from 0 to 20%, fully covering the national standard test range;
In the protection function test, ANBGS can simulate various faults to ensure that the inverter's over-voltage, under-voltage, over-frequency, under-frequency and other protection functions meet the standard response time requirements, helping the company's products pass the certification smoothly.
Energy feedback technology to achieve cost reduction and efficiency improvement
During the test process, traditional test equipment converts a large amount of electrical energy into heat energy consumption, causing energy waste and increasing the company's testing costs. ANBGS's unique energy feedback technology can efficiently feed back the excess electrical energy generated during the test to the grid, with an energy feedback efficiency of more than 95%.
Take a company with an annual output of 100,000 photovoltaic inverters as an example. Using ANBGS for testing can save more than one million yuan in electricity bills each year, greatly reducing testing costs. At the same time, the reduced energy consumption and carbon emissions are also in line with the global green development concept, helping enterprises achieve sustainable development.
Intelligent testing platform to improve testing efficiency
ANBGS is equipped with an intelligent testing platform and supports automated testing processes. Through preset test plans, multiple test items such as electrical performance, grid adaptability, and protection functions can be executed with one click, and the testing efficiency can be increased by more than 3 times. The platform also has powerful data processing and analysis capabilities, can generate test reports in real time, automatically compare test data with standard requirements, and quickly locate product performance defects.
In addition, the platform supports remote monitoring and cloud data storage. Enterprise technicians can view test progress and retrieve test data in real time through the network, which is convenient for remote collaboration and technical analysis, and effectively shortens product development and optimization cycles.
ANBGS, a simulated power supply that can be fed back to the grid, provides a full range of professional solutions for global photovoltaic inverter testing with its simulation capabilities that fit the characteristics of the grid, adaptability to strict standards, high-efficiency and energy-saving technical advantages, and intelligent testing platforms.
