Application Requirements
The development of photovoltaic inverters requires simulation of grid conditions. The voltage, frequency, phase and other parameters of the actual grid are constantly changing, and abnormal conditions such as voltage sudden change, frequency mutation, harmonic interference and so on may occur. It is very challenging to accurately simulate the changing grid conditions in a laboratory environment, and requires high-precision, high-stability and powerful grid simulation equipment. For example, the simulated voltage fluctuates rapidly by ±20% in a short period of time, and the harmonic components of multiple frequencies are superimposed at the same time. Not only does it require extremely high output accuracy of the equipment, but it also requires precise control of the timing and amplitude of the changes of each parameter. The Ainuo Regenerative Grid Simulator perfectly meets the application requirements.
The Ainuo Regenerative Grid Simulator (RGS) AC power supply is an advanced power electronics test system designed to simulate real grid conditions while recycling energy back to the grid or local power supply, so that high-power devices such as photovoltaic inverters, battery storage systems and electric vehicle chargers can be efficiently tested.
Difficulties in Testing High-Power Photovoltaic Storage Systems
1. Grid adaptability: It is difficult to simulate complex and changing grid conditions, such as parameters such as voltage, frequency, phase, etc. During low voltage ride-through testing, the control drop parameters require high requirements.
2. Protection function: It is difficult to accurately simulate faults, and balance the rapidity and accuracy of protection.
3. Power quality: The high-order and interharmonic content is low and wide, and it is difficult to measure and analyze.
Ainuo Solution
