| 摘要: |
| 针对复杂工业过程，以过程参数免疫时间(PIT)为电压暂降耐受力指标，提出一种考虑运行方式影响以及多设备备用情形的工业过程电压暂降耐受特性评估方法。首先，分析当前运行方式下节点的连通性，结合电压暂降发生点分析影响范围；其次，建立原始过程故障树并根据受扰设备的判断结果进行修正，得到受扰过程故障树；最后，利用单一设备的PIT计算全过程PIT以评估全过程的电压暂降耐受特性。对某实际薄膜晶体管液晶显示器(TFT-LCD)生产过程进行实例分析，证明该方法的正确性和可行性。 |

| Abstract: |
| Aiming at complex industrial processes, a method considering the influence of operation mode and equipment standby for evaluating the voltage sag tolerance characteristics of industrial processes is proposed, which takes the PIT(Parameter Immunity Time) as the voltage sag tolerance index. The connectivity of nodes under current operation mode is analyzed, and the impact range is analyzed with the occurrence point of voltage sag. Then the original process fault tree is established and corrected according to the judgment result of the disturbed equipment. The whole process PIT is calculated by using PIT of a single device to evaluate the whole process voltage sag tolerance characteristics. The production process of an actual TFT-LCD(Thin Film Transistor Liquid Crystal Display) is analyzed and the analytical results prove the correctness and feasibility of the proposed method. |
