s130, collecting wind power data of each fixed period corresponding to the touch state of the insulating jumper, judging whether the wind power data is matched with the touch state, and reporting abnormal installation of the insulating jumper when the wind power data is not matched with the touch state for a set number of times.
When the operation management of the insulated jumper is carried out, the embodiment of the application detects the discharge condition, the abrasion condition and the installation condition of the insulated jumper respectively so as to report the abnormality under the corresponding abnormal condition. Therefore, operation and maintenance personnel are prompted in time to process the abnormality, the operation safety of the line is guaranteed, and potential faults are avoided.
As shown in fig. 2, the insulated jumper 101 is disposed corresponding to the overhead iron tower 102, which is a transition wire on the high-voltage transmission line and used for crossing the overhead iron tower part. In order to avoid abnormal discharge caused by touching the overhead iron tower, the part of transition wire is provided with a corresponding wire insulating layer so as to avoid the wire from touching the overhead iron tower to carry out instantaneous discharge. Further, since frequent touching of the insulating jumper wire to the overhead iron tower in windy weather may cause line wear, wear of the insulating layer may affect the insulating performance thereof. Based on the above, the embodiment of the application starts from three aspects of discharge condition, abrasion condition and installation condition, detects three abnormal conditions which possibly cause discharge faults, and timely reports and processes the abnormal conditions, thereby improving the running safety of the circuit.
Referring to fig. 3, an embodiment of the present application provides an insulated jumper operation management system for a high-voltage power transmission line, which includes a control device 11, a temperature sensor 12, a vibration sensor 13, a wind sensor 14, and an electromagnetic monitoring module 15 that are disposed on the insulated jumper. The temperature sensor and the electromagnetic monitoring module are arranged corresponding to the preset predicted touch positions of the insulating jumper and the overhead iron tower;
The temperature sensor is used for collecting temperature data of a corresponding position in real time, the electromagnetic monitoring module is used for collecting electromagnetic data of the corresponding position, the wind sensor is used for collecting wind power data of the corresponding position, and the vibration sensor is used for collecting vibration data of the corresponding position;
the control equipment is used for collecting real-time temperature data and electromagnetic data, judging whether the temperature data and the electromagnetic data are in a set parameter rising state or not under the condition that the temperature data or the electromagnetic data exceed standards, if so, reporting line discharge abnormality, and if not, reporting line parameter exceeding standards abnormality;
the control equipment is also used for collecting vibration data in a fixed period, quantifying the vibration data to generate vibration variation waveforms in the fixed period, judging whether the vibration variation waveforms are matched with pre-stored abnormal waveforms, and the abnormal waveforms are generated by collecting vibration data of the insulating jumper wire touching the overhead iron tower in advance; under the condition that the vibration change waveform is matched with the abnormal waveform, determining that the current insulating jumper is in a touch state, and reporting abnormal abrasion of the insulating jumper under the condition that the insulating jumper is detected to be in the touch state during a continuous set time length;
The control equipment is also used for collecting wind power data of each fixed period corresponding to the touch state of the insulating jumper, judging whether the wind power data is matched with the touch state, and reporting the abnormal installation of the insulating jumper under the condition that the wind power data is not matched with the touch state for a set number of times.
The control device of the insulated jumper operation management system for the high-voltage transmission line is used for executing the insulated jumper operation management method for the high-voltage transmission line in the steps S110-S130. In the running process of the system, the discharge condition of the system is analyzed by collecting real-time temperature data and electromagnetic data. It can be appreciated that the damage of the insulating layer of the insulating jumper wire can cause the high temperature condition at the local position under the condition of discharging when touching the overhead iron tower. And in the discharge situation, the electric field and the magnetic field also change. Based on the above, according to the embodiment of the application, the temperature sensor and the electromagnetic monitoring module are arranged corresponding to the preset predicted touch position of the insulating jumper and the overhead iron tower so as to acquire temperature data and electromagnetic data, and whether the insulating jumper is abnormal in discharge or not is analyzed. Note that, the present application is not limited to the above-described embodiments. The set predicted touch position is set according to the position which is likely to touch the overhead tower when the insulating jumper is installed. And setting a temperature sensor and an electromagnetic monitoring module by an installer according to the position which is possibly touched so as to acquire data and perform anomaly analysis.
Wherein the electromagnetic data includes electric field monitoring data and magnetic field monitoring data. One end of the electromagnetic monitoring module is used for respectively collecting electric field monitoring data and magnetic field monitoring data through the electric field sensor and the magnetic field sensor. After the electric field signals and the magnetic field signals at the corresponding positions are acquired, the electric field signals and the magnetic field signals are subjected to signal amplification and filtering processing by a signal processor and then are converted into electric field monitoring data and magnetic field monitoring data, namely the electromagnetic data.
For the initial electric field signal acquired by the electric field sensor, the electric field signal is processed into an electric signal which can be identified by the system, namely electric field monitoring data by an electric field signal processor. The electric field signal processor amplifies the electric signal through the signal amplifying circuit to obtain an amplified electric signal; the amplified electric signal is subjected to low-pass filtering treatment through a low-pass filtering circuit to obtain a filtered electric signal; and finally, performing AC-DC conversion on the filtered electric signal through an AC-DC conversion circuit to obtain final electric field monitoring data.
Similarly, the initial magnetic field signal acquired by the magnetic field sensor is processed into a magnetic signal which can be identified by the system, namely magnetic field monitoring data by a magnetic field signal processor. The magnetic field signal processor amplifies an initial magnetic field signal through the signal amplifying circuit; and then the amplified magnetic field signal is subjected to band-pass filtering by a band-pass filtering circuit, and final magnetic field monitoring data is output.
After the electric field and magnetic field monitoring data are obtained through the analog-to-digital conversion, the electromagnetic data are reported to the control equipment. On the other hand, the two parts of data are respectively compared with a set threshold value by acquiring the temperature data, and when the threshold value is exceeded, the temperature data or electromagnetic data is determined to be out of standard. Before that, temperature and electromagnetic data of the insulated jumper in normal operation are detected in advance, so as to be used for setting corresponding threshold information.
Further, in order to avoid that the discharge abnormality detection is affected by the data exceeding condition caused by other interference, a detection error occurs. And judging whether the temperature data and the electromagnetic data are in a set parameter rising state or not, if so, determining that the line discharge abnormality occurs, and reporting the line discharge abnormality. If not, the parameters may be out of standard due to other conditions, and only reporting of the out-of-standard abnormality is performed at this time. By detecting the discharge abnormality, the method reports the abnormality timely to inform operation and maintenance personnel to process, and ensures the safe operation of the circuit.
Wherein the determining whether the temperature data and the electromagnetic data are both in a set parameter rising state includes:
determining that the current temperature data is larger than a historical temperature average value, determining that the current electromagnetic data is larger than the historical electromagnetic average value, and determining that the temperature data and the electromagnetic data are both in a set parameter rising state when a period of time when the temperature data is larger than the historical temperature average value is overlapped with a period of time when the electromagnetic data is larger than the historical electromagnetic average value.
It can be appreciated that the moment when the insulating jumper wire has abnormal discharge, the temperature data and the electromagnetic data of the local position are both beyond the historical average value. And, the time periods when the two parameters exceed the standard should be coincident. Based on the above, the embodiment of the application determines whether the insulated jumper wire has abnormal discharge or not by accurately detecting whether the temperature data and the electromagnetic data are in the set parameter rising state, and reports the abnormal discharge. Therefore, the detection accuracy of discharge abnormality can be improved, and detection errors are avoided.
On the other hand, because the discharge abnormality of the insulating jumper wire is simply detected or the abnormal treatment is too delayed, the potential discharge abnormality cannot be treated in advance, and the discharge abnormality is avoided. Based on the above, the embodiment of the application quantifies the vibration data by collecting the vibration data of a fixed period. For example, vibration data in a corresponding value range is quantized to 1, 0 or-1 according to different values of the vibration data. Thus, a vibration variation waveform represented by a fixed value can be obtained, and the vibration condition of the insulating jumper is represented by the waveform.
Before the vibration data are acquired in a fixed period according to the condition that the insulating jumper touches the overhead iron tower, the vibration data are quantized into vibration waveforms according to the data quantization method, and the vibration waveforms are defined as abnormal waveforms. It can be appreciated that if the vibration variation waveform is matched with the abnormal waveform, the current insulated jumper and the overhead iron tower can be considered to have a touch state. Frequent touches can wear the insulating layer of the insulating jumper wire, so that the insulating performance is reduced, and the discharge abnormality occurs. Based on the above, in the case that the continuous set time length detects that the insulating jumper is in the touch state, the embodiment of the application reports the abnormal abrasion of the insulating jumper, and timely informs operation and maintenance personnel to process the abnormal situation, so that the further abrasion of the circuit is avoided.
Wherein the judging whether the vibration variation waveform matches a pre-stored abnormal waveform includes:
and aligning the vibration variation waveform and the abnormal waveform, counting the matching time length of the vibration variation waveform which is the same as the signal value of the abnormal waveform, calculating a matching rate according to the matching time length and the fixed time period, and judging whether the vibration variation waveform is matched with the pre-stored abnormal waveform or not based on the matching rate.
When the vibration variation waveform and the abnormal waveform are matched, the waveforms of the two fixed time periods are aligned, then the time periods with the same signal values are counted, and the time periods are accumulated and defined as the matching time length. The matching duration identifies a set of times when waveform signal values of the vibration variation waveform and the abnormal waveform are the same. Dividing the matching time period by the fixed time period results in a matching rate. If the matching rate reaches a set matching threshold (e.g., 80%), the vibration variation waveform is considered to match the pre-stored abnormal waveform, otherwise, the vibration variation waveform and the abnormal waveform are not matched.
It can be understood that when the insulating jumper touches the overhead iron tower, the vibration waveform of the insulating jumper is regular. Based on the rule, the vibration change waveform is constructed by quantifying the vibration data, and based on the matching result of the vibration change waveform and the pre-stored abnormal waveform, the touch state of the insulating jumper can be accurately detected. And further reporting abnormal abrasion under the condition of frequent touch.
In order to accurately detect the touch condition of the circuit, the embodiment of the application also acquires wind power data of each fixed period through the touch state of the corresponding insulating jumper, and judges whether the wind power data is matched with the touch state. It will be appreciated that insulated jumpers typically do not touch the overhead pylon without wind forces. Therefore, by detecting the corresponding wind power data in the touch state, whether the current touch state is caused by wind power is judged. If yes, the wear is processed according to normal abnormal wear logic. If not, besides the abrasion exception handling logic, whether the line is in safety exception or not is judged according to the number of times that the wind power data is not matched with the touch state, so that the line is frequently touched on the overhead iron tower due to falling. And when the number of times that the wind power data is not matched with the touch state reaches the set number of times, the line is considered to be safe abnormal. At the moment, the abnormal installation of the line is reported, and operation and maintenance personnel are timely informed of overhauling the line, so that the operation safety of the line is ensured.
Wherein the determining whether the wind power data matches the touch state includes:
inquiring a pre-constructed mapping relation table according to the vibration data corresponding to the touch state, determining a wind power data range mapped with the vibration data, judging whether the wind power data is matched with the touch state according to whether the wind power data falls into the wind power data range, and setting the mapped wind power data range according to different vibration data by the mapping relation in advance.
When detecting whether the wind power data is matched with the touch state, the embodiment of the application inquires a pre-constructed mapping relation table according to the vibration data corresponding to the touch state and determines the wind power data range mapped with the vibration data. It can be understood that the vibration data of the circuit are different under the drive of different wind power data. The larger the wind power is, the larger the vibration data is, and the two are in positive correlation. The range of wind data to which the different vibration data may be mapped is determined by a predetermined. When the vibration data is not matched with the wind power data in the touch state, namely the wind power data does not fall into the wind power data range, the wind power data is considered to be not matched with the touch state. At this time, the line touch caused by wind power may not be caused, and the corresponding installation abnormality is reported. Otherwise, normal wear exception handling logic is installed to operate. Therefore, by reporting the abnormality aiming at different conditions, more efficient and reliable operation management is realized.
The method comprises the steps of acquiring real-time temperature data and electromagnetic data, judging whether the temperature data and the electromagnetic data are in a set parameter rising state or not under the condition that the temperature data or the electromagnetic data exceed standards, if so, reporting that the line discharge is abnormal, and if not, reporting that the line parameter exceeds standards; collecting vibration data in a fixed period, quantifying the vibration data to generate vibration variation waveforms in the fixed period, judging whether the vibration variation waveforms are matched with pre-stored abnormal waveforms, and generating the abnormal waveforms in advance based on vibration data collection of the insulating jumper touching the overhead iron tower; under the condition that the vibration change waveform is matched with the abnormal waveform, determining that the current insulating jumper is in a touch state, and reporting abnormal abrasion of the insulating jumper when the insulating jumper is detected to be in the touch state in a continuously set time length; and acquiring wind power data of each fixed period corresponding to the touch state of the insulating jumper, judging whether the wind power data is matched with the touch state, and reporting abnormal installation of the insulating jumper under the condition that the wind power data is not matched with the touch state for a set number of times. By adopting the technical means, the management effect of the insulating jumper can be optimized by monitoring and reporting various abnormal conditions of the insulating jumper, and the operation safety of the insulating jumper is improved.
