First of all, the operation of inductive equipment must establish a magnetic field (such as a motor). Since the instantaneous start-up of large equipment requires the power grid to provide a large amount of Reactive Current to establish a magnetic field, the voltage of the system will be greatly reduced at the moment of equipment startup, causing other equipment to be protected or unable to operat...

UPS and Energy Storage Technology are two different power systems. Their main differences lie in their working principles, application scenarios, and energy storage methods. The main working principle of UPS is to convert the input AC power into DC power through power conversion circuits and batteries and other devices, and then convert it back to AC output through inverters. When the input power ...
