Problems solved by technology
The above-mentioned traditional fault diagnosis system only responds to protection action signals and analog faults, and does not deal with other switch displacements, which makes it impossible for the dispatcher to quickly understand the abnormal information caused by these switch displacements. It is also impossible to send the effective fault analysis report to the D5000 dispatching automation system

Embodiment Construction
[0039] Such as figure 1 As shown, a kind of fault diagnosis and analysis method based on switch quantity state provided by the present invention comprises:
[0040] Step 1: Obtain the wave recording file of the sub-station, and judge whether there is an INF file in the sub-station;
[0041] Step 2: Based on the judgment result of step 1, obtain the switching quantity action number of the wave recording file, and then generate a fault diagnosis report according to the switching quantity movement number;
[0042] Said step 2 includes:
[0043] Step 2.1: When the substation has an INF file, call the sub-fault analysis library, and then enter step 2.2; when the substation does not have an INF file, obtain the switching value action number of the wave recording file, and then enter step 2.4;
[0044] Step 2.2: Obtain the status of the analog quantity of the recorded wave file. When the analog quantity has no faults, obtain the number of switch actions, and judge whether there is ...

The invention relates to the field of recording and networking fault diagnosis of a power system and discloses a fault diagnosis grading system based on an on-off state. By calculating on-off movement quantity in a recording file and combining analysis on an analog quantity, faults are divided into three grades and sent up to a D5000 dispatching automation system, so that dispatching staffs can know about faults, disturbance and abnormal states during operation of the power system and take different processing schemes by analyzing severity of a report, and normal operation of the power system can be recovered quickly. Meanwhile, fault information with different degrees can be sent up to the D5000 dispatching automation system under the conditions that no substation INF file is allocated. By means of the fault diagnosis grading system, fault diagnosis can be sent up to the D5000 dispatching automation system in a grading mode by means of the on-off movement quantity in the recording file, therefore, dispatching staffs can know about operation conditions of the system in details, and the problem that the traditional fault diagnosis system cannot analyze the faults without the INF file is solved. Furthermore, dispatching staffs can take measures to recover normal operation of the power system quickly.
Description
technical field [0001] The invention relates to a fault diagnosis system for networked wave recording of a power system, in particular to a fault diagnosis and classification method and system based on the state of a switching quantity. Background technique [0002] The network of fault recorders has been widely promoted and applied in power grids at all levels of the power system. By establishing a small master station for ground adjustment and using the established dedicated network as a carrier, the fault data of the fault recorder in the jurisdiction can be communicated remotely through the network, and the data network can be fully utilized. The resources connect all the fault recording devices of the substation to the network to realize the preprocessing and remote retrieval of the line fault data of the distance measuring equipment. Establish a fault recording information management system at the recording master station to conduct online health detection and monitori...
