[0002] The water-turbine-generator-unit is usually provided with a guide bearing system composed of an upper guide bearing, a lower guide bearing, a water guide bearing and a thrust bearing. The upper guide bearing mainly bears the radial mechanical unbalance force and electromagnetic force generated during the operation of the unit to inhibit the shift of the shaft line of the generator; the water guide bearing is responsible for bearing the radial load transmitted by the main shaft to ensure the stability of the shaft line of the unit; the lower guide bearing assists in sharing the radial mechanical and electromagnetic load; and the thrust bearing bears the weight of all rotating parts and the maximum water thrust of the water turbine. The guide bearings are correspondingly provided with upper guide pads, lower guide pads, water guide pads and thrust pads: the former three are distributed radially along the circumference of the main shaft, and the thrust pads are arranged axially below the mirror plate. The bearing shell, as the core component of the guide bearing, directly reflects the operation state of the unit and the health condition of the bearing system, and is a key parameter for safety monitoring.
[0003] At present, the monitoring of the temperature of the bearing shell by the computer monitoring system mainly relies on conventional charts, and such display mode has significant limitations: on the one hand, it cannot directly present the statistical characteristic values such as the maximum value, the minimum value and the average value of the temperature; on the other hand, it is difficult to express the temperature distribution gradient in the circumferential direction or the axial direction of the bearing shell, resulting in an unclear spatial situation of the temperature field.
[0004] The above-mentioned defects seriously restrict the operation monitoring efficiency, and the operation personnel cannot quickly locate the abnormal temperature rising point, nor can they grasp the temperature distribution law as a whole, which is not conducive to early warning of faults and accurate assessment of the state of the unit.

[0022] The embodiments of the present application will be described in detail below with specific examples. Those skilled in the art can easily understand other advantages and effects of the present application from the disclosure. The present application can also be implemented or applied by different specific embodiments, and the details in the specification can be modified or changed based on different views and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.
[0023] Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.
[0024] Please refer to Figure 1 , Figure 1 A flowchart of a water turbine generator set bearing temperature display method according to an embodiment of the present application is shown. The method comprises: Step S1, constructing a pie chart display interface.
[0025] The pie chart comprises a plurality of bearing number boxes, bearing temperature boxes corresponding to the bearing number boxes one by one, abscissa and ordinate.
[0026] A pie chart is constructed on the display interface of the computer monitoring system, which is used to display the bearing temperature information of the water turbine generator set guide bearing system. The pie chart comprises a plurality of bearing number boxes, each bearing number box corresponding to a bearing temperature box, and the pie chart is also equipped with abscissa and ordinate for assisting positioning and displaying the position relationship of the bearing. The arrangement of these bearing number boxes and bearing temperature boxes on the pie chart should be consistent with the actual position distribution of the field bearings.
[0027] Step S2, collecting real-time temperature data of each bearing bush in the guide bearing system of the hydro-generator unit; Each bearing bush in the guide bearing system of the hydro-generator unit is provided with a temperature measuring element for collecting real-time temperature data of the bearing bush. The temperature measuring elements are connected to the computer monitoring system and can transmit the collected temperature data to the database of the monitoring system in time.
[0028] Step S3, displaying the bearing bush number in the bearing bush number box and displaying the corresponding bearing bush temperature value in the bearing bush temperature box.
[0029] The number of the corresponding bearing bush is displayed in the bearing bush number box of the pie chart, so that the running personnel can quickly identify each bearing bush. At the same time, the real-time temperature value collected from the bearing bush is displayed in the form of Arabic numerals in the bearing bush temperature box corresponding thereto. For example, if a bearing bush number is “1” and the corresponding temperature is “85℃”, “1” is displayed in the number box “1” and “85” is displayed in the corresponding temperature box “17”.
[0030] Step S4, arranging the bearing bush number boxes in the pie chart according to the actual position distribution of the bearing bushes.
[0031] According to the arrangement position of the bearing bushes in the actual field, the bearing bush number boxes in the pie chart are arranged according to the same mutual position relationship. For example, if the bearing bush “1” and the bearing bush “2” are arranged adjacently on the same side of the main shaft in the field, the number box “1” and the number box “2” should also maintain an adjacent arrangement relationship in the pie chart, so as to ensure that the pie chart can intuitively reflect the actual layout of the bearing bushes.
[0032] Step S5, filling the corresponding color for each bearing bush number box according to the bearing bush temperature value; According to the collected bearing bush temperature value, the corresponding color is filled for each bearing bush number box according to the “Infrared Image Temperature Representation Rule RGB Method” (GB / T44006). With the change of temperature, the color of the bearing bush number box will also change accordingly. For example, if the bearing bush temperature is high, the number box may be filled with red; if the temperature is moderate, it may be filled with yellow; if the temperature is low, it may be filled with green.
[0033] Step S6, using different thickness of the border to distinguish and identify the bearing bush number box and the bearing bush temperature box corresponding to the maximum value, the minimum value and the average value of the bearing bush temperature; The maximum, minimum and average (or the value closest to the average) of the bearing temperature are distinguished by different thickness of the border of the bearing number box and the bearing temperature box. The border of the maximum is the thickest, the average (or the value closest to the average) is the second, and the minimum is the thinnest. These borders are obviously different from the borders of the remaining ordinary bearing number boxes and temperature boxes. For example, the border of the maximum is 3 pixels wide, the border of the average is 2 pixels wide, and the border of the minimum is 1 pixel wide.
[0034] In step S7, a superscript is added to the value in each bearing temperature box, and the superscript shows the deviation of the bearing temperature from the average value.
[0035] A superscript is added to the temperature value displayed in each bearing temperature box, and the content of the superscript is the deviation of the bearing temperature from the average temperature. The calculation method of the deviation value is: the single bearing temperature minus the average value of all bearing temperatures.
[0036] Please refer to Figure 2 , Figure 2 The interface layout of the bearing temperature display method based on the water turbine generator set is shown. The bearing number is displayed in the bearing number box (1-16), and the bearing temperature value is displayed in the bearing temperature box (17-32). The temperature is collected by the field bearing temperature measuring element. The bearing distribution is displayed in the form of a pie chart. The actual position distribution of the bearing in the field and the position of the bearing in the pie chart should be consistent. The bearing number box and the bearing temperature box corresponding to the maximum, minimum and average (or the value closest to the average) of the bearing temperature are distinguished by different thickness of the border. The border of the maximum is the thickest, the average (or the value closest to the average) is the second, and the minimum is the thinnest. They are all different from the borders of the remaining bearing boxes. When there are multiple bearings corresponding to the maximum, minimum or average, the bearing number boxes and bearing temperature boxes with the same characteristic value are distinguished by the same border thickness.
[0037] When there are multiple bearings corresponding to the maximum, minimum or average, the bearing number boxes and bearing temperature boxes with the same characteristic value are distinguished by the same border thickness.
[0038] If the temperatures of multiple bearings are the same maximum, their number boxes and temperature boxes all use the thickest border. If the temperatures of multiple bearings are the same average or the value closest to the average, they use the second thickest border. If the temperatures of multiple bearings are the same minimum, they use the thinnest border. In this way, even if there are multiple bearings with the same characteristic value, they can be distinguished by the same border identification method.
[0039] The deviation value is displayed in the form of “± value”, a positive value indicates higher than the average value, and a negative value indicates lower than the average value.
[0040] In the water turbine generator set bearing temperature display method, the deviation value of each bearing temperature frame from the average value is displayed on the upper label of the numerical value, and the deviation value is presented in the form of “± value”. Specifically, when the bearing temperature is higher than the average value, the deviation value is displayed as a positive value (such as +5℃), indicating that the bearing temperature is 5℃ higher than the average temperature; and when the bearing temperature is lower than the average value, the deviation value is displayed as a negative value (such as -3℃), indicating that the bearing temperature is 3℃ lower than the average temperature.
[0041] The horizontal and vertical coordinates are used to locate the center point of the pie chart and the angle direction of the bearing.
[0042] In the pie chart of the water turbine generator set bearing temperature display method, the horizontal and vertical coordinates are used to locate the center point of the pie chart and the angle direction of the bearing. The horizontal coordinate usually represents the horizontal position, and the vertical coordinate represents the vertical position. The center point of the pie chart is the intersection of the horizontal and vertical coordinates, and the angle direction of each bearing in the pie chart can be determined based on this center point, ensuring that the position of the bearing in the pie chart is consistent with the position distribution in the actual field.
[0043] The water turbine generator set guide bearing system includes at least one of the upper guide bearing, the lower guide bearing, the water guide bearing or the thrust bearing.
[0044] The guide bearing system of the water turbine generator set is an important support component of the unit, and according to the specific design and operation requirements, at least one of the upper guide bearing, the lower guide bearing, the water guide bearing or the thrust bearing is included.
[0045] The average value adopts the arithmetic mean, or when the arithmetic mean has no corresponding bearing, the bearing temperature value is adopted.
[0046] When calculating the average value of the bearing temperature, the arithmetic mean method is first adopted, that is, the temperature values of all bearings are added and divided by the total number of bearings. If the arithmetic mean coincides with the actual temperature of a bearing, the temperature of this bearing is directly identified as the representative of the average value. However, if the arithmetic mean cannot be accurately matched to the specific temperature value of any bearing, the temperature value of the bearing closest to the arithmetic mean is selected as the representative of the average value.
[0047] The difference in thickness of the frame is realized by pixel width or line width level, and is different from the frame style of the bearing without marked characteristic value.
[0048] In order to visually distinguish the bearing with different characteristic values (such as maximum value, minimum value, average value) from other ordinary bearings when displaying bearing temperature information, a visual identification method of border thickness difference is adopted, and the difference is realized by setting different pixel width or line width levels.
[0049] Compared with the prior art, the embodiments of the application have the following beneficial effects: First, the bearing temperature is displayed in the form of a pie chart, so that the running personnel can intuitively understand the distribution of the bearing temperature. The bearing number box and the temperature box are arranged according to the actual position on site, combined with color filling (according to the "infrared image temperature representation rule RGB method"), which enhances the visibility of the temperature information, so that the running personnel can quickly identify the temperature abnormal area.
[0050] Second, the maximum value, minimum value and average value in the bearing temperature are specially identified, and the bearing number box and the temperature box corresponding to these key characteristic values are distinguished by different border thicknesses.
[0051] Third, the numerical superscript of each bearing temperature box shows the deviation value of the bearing temperature from the average value, which provides detailed temperature deviation information for the running personnel.
