Abstract

The invention provides a UMDs system reliability evaluation method, which relates to the technical field of UMDs uninterruptible power supply. The UMDs system reliability evaluation method features that the reliability index of UMDs system is established, and the power loss model of UMDs system is established; finally, the improved Monte Carlo method is used to evaluate the reliability of UMDs system. The invention provides a UMDs system reliability evaluation method, which can quickly and accurately evaluate the continuous power supply capability of the UMDs system, and find out weak links affecting the system reliability level to seek measures for improving the reliability level, so as to improve the continuous power supply capability of the UMDs system. The improved Monte Carlo method can significantly reduce the sampling variance under the premise of ensuring the accuracy of the calculation, thereby improving the computational efficiency, accelerating the convergence rate and reducing the hardware requirements.

Description

technical field [0001] The invention relates to the technical field of UMDs uninterruptible power supply, in particular to a UMDs system reliability evaluation method. Background technique [0002] Due to the complexity of power generation and power consumption in my country's mains network, backward equipment and poor management, the quality of the AC power we use is poor, and the voltage fluctuation range is large, ranging from 170-250V (320-450V), and the electromagnetic harmony Wave interference is serious, and at the same time, due to power shortages, power outages occur in many areas from time to time. Demand for loads with high power supply quality. Sensitive loads such as precision machining, electronics manufacturing enterprises, and data centers have extremely high requirements on power quality. For example, once a voltage sag or short-term voltage interruption occurs on the power supply bus of an integrated circuit manufacturing enterprise, it will cause a large n...
