Data Center Module-Based UPS Management

Abstract

The invention relates to a modular UPS system used in data centers, where each UPS module's output or associated load arm is connected to a segmented distribution board via a selective protection unit, detecting which module / load arm has experienced a short-circuit current and cutting off power only to that module or its output arm, thus isolating the short-circuited IT device or PDU line while other UPS modules and other PDU / IT loads continue to be powered.

This explanation is provided solely to facilitate a better understanding of the subject. A modular UPS system contains multiple UPS power supplies that power data center critical loads. Modular UPS cabinet (1) containing module (2), 15 in parallel inside modular UPS cabinet (1) UPS power modules (2) that work and share the load, each UPS power module (2) or module with Separate quick-circuit breaker, electronic circuit breaker, contactor or selective protection for the associated load arm. Using the element, the short-circuited branch is disconnected and the other loads of the healthy modules are connected. Module-based selective output protection unit (3) that enables the UPS power to continue supplying power. module (2) output, secondary distribution board (5) output, PDU supply or IT device arm 20 By measuring the high current and fault behavior that occurs, we can identify which module / load branch the fault is in. The short circuit detection system (4) detects that a short circuit has occurred and the output of the modular UPS cabinet (1) is single PDUs are configured as separate outputs based on modules or load groups, rather than as a common line. When the distribution branch and the faulty branch are isolated, it allows other distribution sections to remain energized. The partitioned secondary distribution board (5), short-circuited PDUs and IT devices 25 (6) representing healthy PDU and IT loads, PDU output or IT device where the short circuit occurred faulty PDU line / faulty IT device (7), faulty UPS module (2), faulty PDU line (7), Shows the status of faulty IT device (7) and healthy loads (6) as an alarm to the technical staff DCIM includes alarm display (8). In a modular UPS system, under normal operating conditions, inside the modular UPS cabinet (1) The UPS power modules (2) located on the site jointly power the data center load. Module-based selective output protection unit (3), each UPS power module (2) or load arm associated with the module It connects to the partitioned secondary distribution panel (5) via separate protection elements; PDUs and associated IT loads can also be routed through the partitioned secondary distribution board (5) 35 It feeds. 4 The modular UPS system detects current and electrical conditions in the output arms using short circuit detection. The system monitors continuously via (4). On an IT device, PDU line or related distribution branch When a short circuit occurs, the short circuit detection system (4) detects the fault current and possible In applications where a fault is associated with the load arm, the module-based selective output can be identified. It creates an activation command to the protection unit (3). 5 Module-based selective output protection unit (3) can protect the main UPS output or healthy load arms. Instead of disconnecting them all at once, it isolates only the output branch associated with the fault. Thus, while the faulty PDU line or IT device (7) is de-energized, the healthy PDU and IT loads (6) is intended to continue being powered via available UPS power modules (2). 10 Fault occurrence, opening process, faulty load arm and working status of healthy loads (6) The information is transmitted to the DCIM / BMS monitoring and alarm screen (8). The operator detects the fault via the alarm information. By determining the location of the section, the intervention can only be performed on the relevant load arm. This operating principle allows a short circuit in a sub-distribution branch to disrupt the entire UPS output. limiting the impact, selectively isolating the failure, and in the data center The aim is to maintain the energy continuity of healthy IT loads (6).
