Uninterruptible Power Supply System When utility mains are not available, electricity can be supplied from a source such as a standard connected equipment UPS, which provides power supply. UPS is mostly used for critical loads and is kept between commercial utility mains.
Abstract. In the modern world, when there is a power outage or a power failure, telecommunication systems, computer systems, and many other critical equipment, such as medical equipment, require uninterrupted power to support their operation. Uninterruptible power supply (UPS) systems are used for this purpose.
Conceptual diagram of unified control scheme for uninterruptible power supply system. Because of the three-phase four-wire configuration, the control for each phase in both the PWM rectifier and inverter can be decoupled. Therefore, a single-phase independent control approach can be adopted.
Figure 15.39. Output phase regulation for paralleled uninterruptible power supply system. When the active circulating current and reactive circulating current in the parallel system are detected in the control system, the increase in the inverter output voltage phase angle is calculated according to Eq. (15.41).
Unified control plant for single-phase pulse-width modulation (PWM) rectifier and PWM inverter in uninterruptible power supply system. Table 15.2. Parameter assignments in unified control plant. The instant variable control is the main function loop. Traditional cascaded control is adopted here.
Simplified single-phase circuit models of uninterruptible power supply system: (A) Pulse-width modulation rectifier; (B) Inverter. By comparing the mathematical models in (15.24), (15.25), a unified control plant for a single-phase PWM rectifier and inverter in the stationary coordinate system can be obtained, as shown in Fig. 15.32.
