出现故障时

• An index , svi , is defined to identify fault . research illustrates that svi index can identify fault completely when fault occurs in temperature sensors and it can only find that fault occurs in flow meters but does n ' t know which is when fault occurs in flow meters
  研究表明，当温度传感器出现故障时， svi指数能很好地做出识别，但当流量传感器出现故障时， svi指数只能辨别出是流量传感器出现故障，而无法进一步识别出具体是哪一个传感器发生了故障。
• With the power system becoming more and more complicated , and the voltage scale becoming higher , system problems are more likely to happen than before . as the most important one in all kinds of security measures , power system " s personnel have concerned relay protection widely
  随着现代电力系统日趋复杂，电压等级的升高，系统出现问题的可能性将比以往有所增加，因此，必须有足够的措施保障系统的安全，将电力系统出现故障时所造成的损失减到最低。
• However , it ca n ' t make sure the load balancing for each engine , which usually happened in the long - time business process in particular . as scheduler leads load unbalance , the multiengine adjusts it among many engines based on appropriate model tactics and information in real time , which improve the efficiency of large scale distributed businesses
  当多引擎间任务调度出现不平衡,导致某些节点负载过重或是某个节点出现故障时,多引擎能够根据相应模型策略和实际的信息来动态调整各节点的负载,这样可以在一定程度上解决有大量分布式事务处理时的性能问题。
• Fault tolerant control is one kind new technique with the aim to enhance the system security and system reliability . ftc is basically depended on a great deal of online detection , parameter identification and model calculation . it can revise the system control rules when the fault occurred and then maintain the system operation according the original goal
  容错控制是一种提高系统安全性和可靠性的新技术，容错控制以大量的在线故障检测、参数辨识和模型计算为基础，在系统出现故障时，适时修正系统的控制率，使系统继续维持既定的运行目标，具有适应能力强、可靠性高、功能强等特点。
• Based on the data on 2010 shanghai grid plan , and taking the two hvdc systems , gezhouba to nanqiao and three gorge to shanghai huaxin , which will have set in shanghai by 2010 as simulation objects , the impacts of multiinfeed hvdc system faults on transient stability of shanghai power grids are studied
  以2010年上海电网规划数据以及届时落点于上海电网的葛洲坝南桥、三峡上海华新2条直流输电系统为仿真研究对象，主要研究了当直流输电系统出现故障时对上海电网的暂态稳定带来的影响。
• The two tools as spare part for each other : one of the tools is working , the other is spare one , and the spare one always track the traceline of the working one , if the working one some problem the spare one can automatically start to ensure no waste of the glass and can ensure the cutting precision
  双刀互为备用：横切机的两把刀设置为一个是工作，另一个是备用，备用刀始终跟踪工作刀的刀痕，当工作刀出现故障时，备用刀自动启动切割，确保不浪费玻璃且保证切割精度。
• When engine damage or malfunction occurs which may be such as to endanger the safe operation of the ship ; when any malfunction occurs which it is believed , may cause damage or break down of propulsion machinery , auxiliary machinery or monitoring and governing systems ; and in any emergency or if in any doubt as to what decision or measure to be taken
  当出现危及船舶安全航行的情况，如机器损坏或出现故障时；当你相信出现的故障会引起动力机械损坏时，辅助机械或检测装置和控制系统；在任何紧急情况下当你拿不准该做什么决定时。
• By specific situations and tasks , personal computers consider three decision projects . firstly , when personal computers turn up fault , the methods of checking fault can find fault component and mechanism . calculating and comparing the consumption of maintenance and replacement can made decision
  由个人计算机具体的情况和任务出发，考虑三种情况的决策：一是当个人计算机出现故障时，应用故障检测方法，找出故障部位、机理，通过维修与更换费用的计算和权衡做出决策，以此来补偿有形磨损。
• The experiment result shows that the control method designed in the dissertation can ensure the steady suspension of the join - structure . when there is something wrong with one suspension point on a join - structure , the variation of suspension clearance of the other is only about 0 . 8mm . it manifests that this method can achieve the join - structure ’ s redundancy function
  本文最后在原理型搭接装置上进行了悬浮控制实验,实验结果表明:文中所设计的控制方法能够实现原理型搭接装置的稳定悬浮,而且搭接装置上的一个点出现故障时,另一个点的悬浮间隙最大增加量仅为0 . 8mm左右,由此说明该方法能够确保搭接结构冗余功能的实现。
• Redundancy controller of the key link and the weak link is realized under the present situation . the multi - model way of system for sensor faults diagnosis and detects is provided according to the special character of the system . it can give an alarm signal and fault code when the system goes wrong
  对系统实行开机自检测，可以及时发现故障并给出故障码，显著改善系统的可测试性和可信度；根据实际情况对系统中重要环节和薄弱环节进行冗余控制；根据系统特点给出了基于多模型的系统、传感器故障检测与诊断方法；系统出现故障时能给出报警信号和故障码，根据故障码和故障树进行故障的快速定位。
