Embodiment Construction

[0052] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0053]In this embodiment, a UMDs system is taken as an example, and a UMDs system reliability evaluation method of the present invention is used to evaluate the reliability of the UMDs system.

[0054] A UMDs system reliability assessment method, such as figure 1 shown, including the following steps:

[0055] Step 1: Establish UMDs system reliability index;

[0056] The reliability index is the basis for quantitatively evaluating the reliability of the UMDs system. According to the characteristics of the UMDs system, the present invention refers to the reliability indexes of electronic equipment and distribution networks, and selects the average system power supply avail...

Abstract

The invention provides a UMDs system reliability evaluation method and relates to the technical field of UMDs uninterruptible power supply. A UMDs system reliability evaluation method, first establishes the UMDs system reliability index, then establishes the UMDs system power loss model; finally utilizes the improved Monte Carlo method to evaluate the UMDs system reliability. The UMDs system reliability evaluation method provided by the present invention quickly and accurately evaluates the continuous power supply capability of the UMDs system, and finds out weak links that affect the reliability level of the system to seek measures to improve the reliability level, thereby improving the continuous power supply of the UMDs system ability. The improved Monte Carlo method can significantly reduce the sampling variance on the premise of ensuring the calculation accuracy, thereby improving the calculation efficiency, accelerating the convergence speed, 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 complicated power generation and power consumption of 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 num...
