Product Description:
The AC Power Grid Simulator series multi-functional single/three-phase feedback grid simulator adopts
pure digital PWM rectification technology, SPWM high-frequency pulse width modulation, and advanced DC digital frequency synthesizer (DDS) waveform generation technology. It has full reverse feedback function, which can feed back all the energy of the input AC source to the grid. It has a high input power factor, low grid pollution, high output waveform quality, and fast dynamic response speed. It can simulate grid voltage disturbances, frequency disturbances, three-phase imbalance, low voltage (zero ride-through) ride-through, and islanding tests. It is used for IEC61000-4-11/13/14/27/28 tests. It is applied to the grid connection performance testing of new energy products such as energy storage inverters, photovoltaic inverters, photovoltaic power stations, bidirectional chargers, and charging piles.
Features
● It adopts advanced SPWM technology and Direct Digital Synthesis (DDS) waveform technology, resulting in high frequency stability and good continuity.
● Multiple simulation options: AC power mode (standard), load mode (optional), DC mode (optional);
● It has the function of overlaying and editing harmonics from 2nd to 50th order;
● Output frequency 10-200Hz (10-1200Hz optional), with 0.01 Hz/10ms variable, can easily and accurately perform underfrequency test and anti-islanding test;
● It supports three modes: LIST, STEP, and PULSE, and has 9 memory settings. It can execute 100 different voltage, frequency, rise time, and runtime settings at a time, and can continuously perform 999, 999 cycle tests. The shortest runtime can be set to 1ms, which can simulate harsh mains power tests and realize voltage and frequency gradual change, step, surge, and notch filtering functions.
● It can perform over/under voltage and over/under voltage tests; the required voltage or frequency change is set on the programmable panel, and after running, each change in voltage or frequency will trigger a level, making this test very accurate and convenient.
● Three-phase independent adjustable, phase angle dynamically adjustable; 2nd-50th harmonic editing function and 16Hz-2500Hz harmonic editing function, which can be used for testing of IEC61000-4-13, GB/T14549-1993, and B/T 24337-2009;
● The waveform start angle can be set, making it suitable for measuring the peak current of nonlinear loads;
● It provides readings such as root mean square voltage, root mean square current, active power, frequency, power factor, and peak current .
● Standard configuration includes RS232, RS485, USB, and LAN communication interfaces / GPIB communication interface is optional;
Application areas
● Photovoltaic inverter and energy storage converter testing : used for anti-islanding protection certification, high/low voltage ride-through (LVRT/HVRT) testing, grid adaptability testing, frequency response testing, and rigorous verification of various national grid connection standards (such as IEEE 1547, VDE-AR-N 4105, GB/T 19964).
● New energy vehicles and charging facilities: Test the adaptability of on-board chargers (OBC) and DC charging piles to grid voltage fluctuations, frequency changes, and instantaneous interruptions to ensure charging safety and the robustness of vehicle electrical systems.
● Uninterruptible power supplies (UPS) and critical power systems: Verify the switching time, output stability and load capacity of UPS in the event of power grid anomalies (such as power outages and voltage drops) to ensure continuous power supply to important loads such as data centers and medical equipment.
● Household appliances and industrial electrical equipment: Assess the performance, reliability, and compliance with relevant electromagnetic compatibility (EMC) and power quality standards of equipment such as air conditioners, motor drives, and PLCs under harsh power grid conditions.
● Aviation and military power supply testing: Utilizing its wide frequency range (up to 1000Hz) and high-precision frequency control, it simulates the AC power networks of special platforms such as aircraft and ships to test the power supply adaptability of airborne/shipborne equipment.
● Power electronic components and module testing: Providing precisely controllable input power with complex disturbances for IGBT modules and power converters for extreme stress testing, life assessment and performance analysis.
