Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, in an embodiment of the present invention, a fault recorder is provided, which includes a main body 1 and a data acquisition and communication module 2; the body 1 is respectively in network communication (as shown in fig. 2, namely, communication is carried out based on a network switch) with a protection device containing an action contact in each line protection (such as line protection, main transformer protection, bus protection and the like) through the data acquisition communication module 2, so that the recording access of different line protection can be met; the main body 1 is configured to perform characteristic judgment according to the relevant action information (reflected by a value of the switching value being 0 or 1) of each action contact in each protection device acquired by the data acquisition and communication module 2 in a broadcast manner, so as to implement fault judgment and start recording. For example, if the value of the switch amount corresponding to a certain operating contact is collected to be 1, it indicates that there is a fault and the operating contact is operated, and at this time, the fault recorder starts recording.
In one embodiment, the following is a detailed description of how to perform characteristic determination on the operation information of each operation contact in each protection device for line protection, main transformer protection, and bus protection:
as shown in fig. 3, when there is no spare contact in the protection device in the 110kV line protection, it can be determined by the change of the contacts such as KKJ and TWJ; one three-jump joint (such as a TJR joint) in 220kV line protection can be judged by a non-starting reclosing and bus differential protection action joint, and the other three-jump joint (such as a TJF joint) in 220kV line protection can be judged by information such as non-starting reclosing, non-starting failure and the like; the hand trip contact of the main transformer protection can be judged according to the switch position and the charging and discharging condition of the spare power automatic switching. Therefore, all the protection action contact points can be judged according to the relevant characteristics of the contact points.
Therefore, the action change information of the internal contact (such as the contacts of KKJ, TWJ, long jump, mother-to-difference action and the like) of the protection device can be transmitted to the fault recorder in a data broadcasting mode, the fault recorder judges according to the received action change information, and whether the recording of the corresponding line is started or not is further determined according to the judgment result.
Compared with the defect that the conventional fault recorder has frequent recording loss or cannot record waves continuously in the starting and recording process, the fault recorder in the embodiment of the invention can adopt a temporary storage function, store other data meeting the recording condition after starting, judge the data property through the body (such as an internal CPU), and reserve key data if a memory means is needed to supplement the recording so as to realize the integrity of the recording. Therefore, the fault recorder further comprises: a memory 3 connected to the body 1; the memory 3 is used for storing other data which are judged by the body 1 to meet the preset wave recording condition in the current wave recording process, so that the body 1 can extract the stored data and supplement the wave recording after the current wave recording is finished, and the completeness of all wave recording data is realized. The memory 3 is a memory block in the fault recorder or a USB flash disk externally connected with the fault recorder.
It should be noted that the satisfaction of the predetermined recording condition can be determined by a voltage jump or a current jump, and if the voltage jump is detected, the recording condition is satisfied.
In one embodiment, when the voltage of the phase line A in the 110kV line protection suddenly changes, the fault recorder is started to record waves. If voltage mutation also occurs after the phase line B lags behind the phase line A for a period of time in the wave recording process of 110kV line protection, the data of the phase line B can be stored at the same time, and after the fault wave recorder completes wave recording of the phase line A, the data of the phase line B in the wave recording process can be extracted and the data missing from the phase line B in the wave recording process of the phase line A can be recorded additionally, so that all wave recording data are complete.
Compared with the defect that most of wave recording information in the traditional fault wave recorder is manually analyzed, the fault wave recorder in the embodiment of the invention can read all wave recording data through the message analysis instruction and automatically analyze the wave recording data to realize real fault recovery. Therefore, the fault recorder further comprises: an auxiliary computing module 4 connected with the body 1; the auxiliary computing module is used for reading all the recording data through the message analysis instruction and further automatically analyzing to realize real fault recovery; the auxiliary computing module 4 reads and automatically analyzes the message through a wireshare packet capturing analysis tool.
In one embodiment, the IEC 60870-5-103 communication protocol has two message formats, namely a fixed frame length message and a variable frame length message, wherein the fixed frame length message is mainly used for transmitting information such as 'call, command, confirmation and response', and the variable frame length message is used for transmitting information such as 'command' and 'data'. For the key point of research when the identifier of the information element in the message is identified, a WireShark packet capturing analysis tool is adopted to decode and automatically analyze the message.
It is understood that the body 1, the data acquisition communication module 2, the memory storage 3 and the auxiliary computing module 4 may be discrete components or may be integrated together.
It should be noted that the fault recorder can also perform network communication with other access interval devices (such as a dc device, a backup power automatic switching device, a stability control device, and the like), and by sorting and judging related information, a stronger wave recording function is realized, and a gap that a contact cannot be accessed can also be made up, as shown in fig. 4.
The embodiment of the invention has the following beneficial effects:
1. compared with the traditional fault recorder, the fault recorder is also provided with a data acquisition communication module which is respectively in network communication with the protection devices containing the action contacts in each line protection, and can perform characteristic judgment according to the relevant action information of each action contact in each protection device so as to realize reliable start of recording for fault judgment, thereby meeting the recording access of different line protection and avoiding the leakage of recording;
2. compared with the traditional fault recorder, the fault recorder is also provided with a memory storage, other data which are judged to meet the preset wave recording condition in the current wave recording process are stored, the stored data can be extracted and the wave recording can be supplemented after the current wave recording is finished, and the completeness of all wave recording data is realized, so that the completeness of all wave recording data can be ensured;
3. compared with the traditional fault recorder, the fault recorder is also provided with an auxiliary computing module, and all recorded wave data are read through a message analysis instruction and are automatically analyzed to realize real fault recovery.
The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention, and it is therefore to be understood that the invention is not limited by the scope of the appended claims.
