In recent years, renewable energy has received lots of attention in particular the huge growth of solar energy and wind power. More and more power systems incorporating into the grid could have a significant impact on the current power system. Thus, many standards were set up for integrating renewable energy into the grid such as UL 1741, IEEE 1547, IEEE 1547.1, and NBT 32004, etc.
Moreover, the Low Voltage Ride-Through (LVRT) feature put forward by various countries stipulates that the grid-connected device such as a solar inverter or wind power generator will continue to supply power, when the grid voltage falls, for a period of time until the grid power returns to normal.
To address these requirements, Chroma has released testing software that can simulate the abnormality/distortion of the electrical mains and power line interference. This graphical human-machine interface software controls Chroma’s regenerative grid simulator, the 61800 Series, which is equipped with four quadrant capabilities to satisfy test demands.
In the example below, the power dropped to 0V for 150ms and resumed 70% of output for 550ms, and then spent 800ms to rise from 70% to 90% output capacity. All these conditions can be easily simulated using the software LIST mode. In addition, a preview of the waveform can be seen on the software.
Chroma’s AC Source Software has functions for , LIST mode, STEP mode, PULSE mode, and User-Defined Waveforms (to simulate distorted or interfered mains power). Also, the inter-harmonic test function can simulate the abnormality of the main electrical power.
Screenshots for the software are shown below:
