Example 1
The existing fault detection system generally uses a relay protection device, the device can only carry out single fault detection, and the protection measures of the device generally occur when a protection circuit has faults, so that the associated equipment can generate linkage faults, further higher loss can be caused, and the existing relay protection device is difficult to accurately provide fault points, states and properties, so that the follow-up maintenance management is troublesome; therefore, improvements are now needed in view of the current situation. Therefore, the present application provides an embodiment of a method for detecting a hidden fault, and fig. 1 is a flowchart of an optional method for detecting a hidden fault according to the embodiment of the present application, and as shown in fig. 1, the method includes the following steps:
step S101, acquiring monitoring data of a target circuit, wherein the target circuit is a protection circuit for protecting a controller. Here, the hidden danger of data trouble that this circuit exists of real-time supervision to this can in time carry out corresponding maintenance before the trouble takes place, avoids equipment to lead to the fact bigger loss after the trouble takes place.
For example: and acquiring one or more of current operation data, voltage operation data, temperature operation data and the like of the target circuit, wherein the data can be specifically adjusted according to actual conditions.
Step S102, comparing the monitoring data with reference data to determine whether the target circuit has fault hidden danger, wherein the reference data is used for determining whether the monitoring data is normal.
1) The monitoring data is subjected to interval calibration (for example, 1.0003 is designated as 1, and 1.91 is designated as 2), resampling (including up-sampling and down-sampling, wherein the down-sampling requires signal decimation, and the up-sampling requires signal interpolation), and preprocessing (such as data cleaning, data integration, data conversion, and data reduction) so as to be compared with the reference data.
2) The P-F interval corresponding to the data type of the monitoring data is obtained, and since the performance life curves of different devices are different, the adapted P-F interval can be selected according to the monitored object (i.e., the data type).
Failure of a device has a process from potential failure to loss of function. In this section, although the fault has occurred, the equipment can still operate without further impact. A section of interval between the latent fault (degradation, hidden trouble) feature of the equipment and the loss of function fault, called P-F interval, and a curve representing the section (the section of curve is a curve of performance y with respect to time x, generally, the value of y decreases with time, P and F are values of y, and P is greater than F) can be called P-F curve, at point P, the potential fault of the equipment already occurs but does not lose its function, and at point F, the equipment already fails. If maintenance is carried out before the point P, preventive maintenance is carried out, namely over-maintenance is carried out. Maintenance after point F, which is a post-mortem repair, will result in production losses and more serious equipment losses. If the repair can be carried out before the point F, the operation and the reliability of the equipment can not be influenced, and the economic effect can be obtained.
3) And under the condition that the monitoring data are located in the P-F interval, determining that the target circuit has fault hidden danger.
4) And under the condition that the monitoring data are located before the P value of the P-F interval, determining that the target circuit has no fault hidden danger.

Optionally, in order to perform fault tracing, after the target circuit is subjected to power failure processing, the monitoring data of the occurrence of an abnormality, a corresponding processing operation, and a processing time may be recorded in a log storage system.
The fault detection log is automatically generated through the log storage system, so that the follow-up tracing of related data is facilitated, the whole system can realize self-acquisition, self-comparison and self-control cutting of data, more intelligent fault detection is realized, the safety and stable operation of the power system are ensured, the workload of manual regular maintenance is reduced, and the management is more convenient.

The middle P point indicates that device performance has begun to degrade and enters a latent fault period. The surface device at point F has lost its intended function, i.e., has developed a functional failure. The various devices and different P-F intervals vary widely, some only a few microseconds, and some up to several decades. The longer P-F interval period allows more time for preventive maintenance.

The conversion unit in the signal conversion system is specifically a digital-to-analog converter, and the digital-to-analog converter is specifically one or a combination of several of an integral digital-to-analog converter, a successive comparison digital-to-analog converter, a sigma-delta modulation digital-to-analog converter or a pressure-frequency conversion digital-to-analog converter.
And S7, the signal execution system receives the pulse control electric signal sent by the signal conversion system and simultaneously cuts off the corresponding protection circuit according to the pulse control electric signal.
