By analyzing, the fault transient component of third harmonic voltage at neutral is approximately equal to that at terminal. Choosing their sum and difference as the action and restrai nt signal respectively, the protection detects the ground fault by comparing the spectrum energy of action and restraint signals.

In doing back-up data, we followed the work to be done is to switch to a system running DOS, and DOS command line in the implementation of "fdisk / mbr" command string to try to repair the hard disk of soft failure occurred ; if such a repair method to try is invalid, then we can go online to download and install the hard drive Bad Track professional testing tool to double-check the local hard disk in the phenomenon of the existence of Bad Track, Bad Track If you can not find the hard disk, it can not detect hard drive through the phenomenon is likely to be caused by the logic of failure, the logical solution is to find a Bad Track Repair Repair Tool to re-click the hard disk, only to do so.

在做好数据的备份工作后，我们接下来要做的工作就是将系统切换到DOS运行状态，并在DOS命令行中执行"fdisk /mbr"字符串命令，来尝试修复硬盘中发生的软故障；要是这种修复方法尝试无效的话，我们可以到网上下载安装一些专业的硬盘坏道检测工具，来仔细检查本地硬盘中是否存在坏道现象，如果找不到硬盘坏道的话，那硬盘检测无法通过的现象很可能是逻辑故障引起的，解决办法就是找逻辑坏道修复工具来重新修复一下硬盘，只能这样做了。

The multi-dimensional signals measured by sensors with a machine working under normal condition or fault condition, can be used to build Q statistic and T^2 statistic respectively to detect the state of the machine. Meanwhile, the feature vector is constructed by the Q value and the T^2 value, the geometrical distance between the normal feature vector and the feature vector H when the machine goes wrong is used to realize the fault location. The results show that the method is feasible.

The method utilizes multi-source,heterogenic sensors to gather data of all kind equipment character and utilizes fuzzy neural network as ex-ecutive institution of diagnosis adjudging to diagnose cause of equipment fault and to assess the equipment running sit uation.

当诊断对象内部结构功能复杂时，为有效判别故障情况必须大量增加检测元件、检测手段以及增加计算复杂度，从而导致故障诊断设备的成本和时间增长。

This intormation is combined in the structure of a Bayesian Graph so as to identify unknown or unpredictable faults. The final experiment results show the intelligent agent can detect network abnormal behavior before a fault actually occurs. Event correlation algorithm for network fault real-time isolation and handle uses object-oriented model method for critical network device and a novel coding scheme, even if in the case of lost alarm and wrong one, it also can identify the fault origin and automatically adapts to changes to network topology to ensure seemless scalability to large and complex network environment. Its performance greatly presides over traditional rule-based event management system.
