Abstract

A method for operation of UPS modules connected in parallel is provided. The method includes: in a case that a UPS system is constructed based on multiple UPS modules connected in parallel, sleeping, based on a system load rate, a predetermined number of UPS modules to control the UPS system to operate at a predetermined efficiency level; controlling UPS modules not being slept in the UPS system to enter into a main-inverter power supply mode or a main-bypass common mode to perform reactive power and harmonic compensation; and waking up the slept UPS modules when the system load rate drops by a predetermined value due to a sudden addition of a load. The UPS modules can be slept or waked up intelligently based on the system load rate in the dynamic online mode, ensuring that the UPS system operates around highest efficiency.
