故障判据 meaning in English
failure criterion
Examples
- In order to select the fault criterion , we refers to some conceptions and methods about probability
在故障判据的选取上文章引用了概率论的一些概念和方法。 - So , when we get the dates of stress and distortion of wing ' s model structure , which have been calculated by computer , we can simulate the dates of the real wing ' s structure , which we will get through stress sensors and distortion sensors . when we transmit those dates to the center computer through remote wireless transmission devices , the computer will analyze those dates according as scientific fault criterion . so we can carry out the remote real - time health monitoring for wing ' s structure
这样，我们读取计算出的机翼结构模型在受力时的应力、变形值就可以模拟出在采用实体机翼作为研究对象时应力、变形传感器传回的数据，把这些数据通过远程无线数据传输设备传到数据处理计算机上采用科学的故障判据对这些数据进行处理就可以实现对机翼结构的实时远程健康监控。 - In order to improve the behavior of transformer protection that is incomplete at present in distinguishing magnetizing inrush current from fault current , the paper puts forward a kind of new principle of transformer differential protection after analyzing the characteristic of magnetizing inrush and active power consume of transformers . this protection uses differential protection based on positive sequence active power as a criterion to discriminate internal faults from magnetizing inrush , and ratio restraint differential current protection as a signal to touch off the protection
针对当前电力系统中变压器保护由于励磁涌流鉴别理论不完善而导致的误动率相对较高的问题，论文在分析了变压器励磁涌流特性和有功损耗的基础上，提出了用变压器正序有功功率差动作为区别励磁涌流和故障电流的判据，并以成熟的比率制动差流保护作为内外部故障判据的变压器主保护。 - In the next place , an improved algorithm of grounding fault location for tree - type distribution system which is based on new fault function and criterion measure , is proposed in order to complete fault branch ide ntification , fault location and fault value . a lot of the simulation of fault diagnosis and location by computer demonstrate that the algorithm is effective
其次论文基于辐射状馈线的任一分支线路发生接地故障，通过分析与推导，建构了配电线路单相短路点定位的故障定位函数和相应的故障判据，利用树网单端信息完成故障分支识别、故障定位和过渡电阻定值。
