Description

Technical Field

[0001] The present invention relates to the field of power transmission, and in particular to a cable operation status monitoring method, device, equipment and medium. Background Art

[0002] Cable is a conductive material consisting of one or more insulated conductors, usually wrapped in an insulating layer and an outer sheath. It is used to transmit power or signals and is widely used in construction, communications, power transmission and other fields. The main components of a cable include: conductor, insulation layer, shielding layer and sheath. According to different uses and structures, cables can be divided into many types, such as power cables, communication cables, fiber optic cables, etc. Different types of cables have different characteristics and scopes of application, which can meet various different engineering needs. Cables play an important role in engineering design and construction. Correctly selecting and using the right cable type can ensure the safe and reliable operation of the electrical system.

[0003] At present, with the rapid development of energy supply demand, cables are getting longer and thicker; longer and thicker cables lead to higher overall construction costs. In order to reduce the cost of cables, the hybrid series connection method of "copper cable + aluminum cable + copper cable" or "copper cable + busbar + copper cable" is adopted in the transmission of electric energy, thereby reducing the use of more expensive copper core cables. The hybrid series connection method can reduce the cost of using cables, but it also increases the number of connection points in the current carrier. If the connection points are not installed properly and the shock absorption is not in place, the connection parts will gradually loosen, the resistance of the connection points will increase, and the connection points will heat up or even burn during operation. Therefore, how to monitor the operating status of the cable and avoid accidents during operation is an urgent problem to be solved. Summary of the invention

[0044] The embodiment of the present application solves the technical problem of single cable monitoring means in the prior art by providing a cable operation status monitoring method.

[0045] The technical solution of the embodiment of the present application is to solve the above technical problems, and the overall idea is as follows:

[0046] A cable operation status monitoring method, the method comprising: determining a target transmission section; acquiring real-time electrical parameters of the target transmission section, real-time temperature parameters of each target cable in the target transmission section, and real-time temperature parameters of each target connection point in the target transmission section, the real-time electrical parameters comprising real-time voltage drop parameters and real-time current parameters; determining the operation status of the target transmission section according to the real-time electrical parameters of the target transmission section, the real-time temperature parameters of each target cable and / or the real-time temperature parameters of each target connection point, the operation status comprising normal operation and abnormal operation.

[0047] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0048] First of all, the term "and / or" in this article is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0049] This application provides Figure 1 A cable operation status monitoring method shown includes steps S11-S13.

[0050] Step S11, determining the target power transmission section.

[0051] Step S12, acquiring real-time electrical parameters of the target transmission section, real-time temperature parameters of each target cable in the target transmission section, and real-time temperature parameters of each target connection point in the target transmission section, wherein the real-time electrical parameters include real-time voltage drop parameters and real-time current parameters.

[0052] Step S13, determining the operating state of the target transmission section according to the real-time electrical parameters of the target transmission section, the real-time temperature parameters of each target cable and / or the real-time temperature parameters of each target connection point, the operating state including normal operation and abnormal operation.

[0053] At present, the connection points between cables with higher voltage levels (usually above 6kV) are usually monitored and protected, but the traditional protection method is not applicable to the connection points between cables with lower voltage levels. In other words, there is currently no monitoring and protection for cables with lower voltage levels (usually below 6kV). In addition, at present, the monitoring of the connection points between cables with higher voltage levels is based on the current passing through. The problems with this method mainly include: the single monitoring method is not accurate and it is impossible to monitor the entire cable, so the monitoring is not comprehensive. Therefore, in response to the above problems, this application proposes a cable operation status monitoring method.

[0054] Regarding step S11 , a target power transmission section is determined.

[0055] The target transmission section in the present application refers to the transmission cable section of one phase of the three-phase alternating current, and the target transmission section can be determined according to actual needs. There is usually a voltage output port and a voltage input port in the target transmission section. The target transmission section and the transmission sections of the remaining two phases together constitute three-phase transmission (three-phase power supply). It can be understood that the transmission sections of the remaining two phases also have a voltage output port and a voltage input port respectively.

[0056] For example, Figure 2 In the example, there are transmission segments A, B and C, which together constitute a three-phase power supply (A, B and C are transmission cable segments of one phase of the three-phase alternating current). Any one of A, B and C can be determined as the target transmission segment according to actual needs. In the following description, A is taken as the target transmission segment.

[0057] Regarding step S12, the real-time electrical parameters of the target transmission section, the real-time temperature parameters of each target cable in the target transmission section, and the real-time temperature parameters of each target connection point in the target transmission section are obtained. The real-time electrical parameters include real-time voltage drop parameters and real-time current parameters.

[0058] After determining the target transmission section, the real-time electrical parameters of the target transmission section can be obtained. The real-time electrical parameters of the target transmission section include the real-time voltage drop parameter and the real-time current parameter of the target transmission section. The real-time voltage drop parameter of the target transmission section is the voltage difference between the voltage input port and the voltage output port of the target transmission section. For details, please refer to (Formula 1):

[0059] UD=Uint-Uout (Formula 1)

[0060] Among them, Uint is the real-time voltage of the voltage input port of the target transmission section, Uout is the real-time voltage of the voltage output port of the target transmission section, and UD is the real-time voltage drop parameter.

[0061] The connection point in the target transmission section refers to the connection point between the cables in the target transmission section. The target transmission section may include multiple connection points, and all the connection points in the target transmission section may be used as target connection points. The real-time current parameter of the target transmission section is the real-time current value of the target transmission section. It should also be noted that the target transmission section may include one or more cables, and the real-time current value of the target transmission section is the sum of the real-time currents of all cables in the target transmission section.

[0062] by Figure 2For example, the target transmission section A includes four cables d, e, f and g. It can be understood that cables d, e, f and g transmit power respectively, and cables d, e, f and g together constitute the target transmission section A. There are eight connection points in cable d, namely, g1, g2, g3, g4, h1, h2, h3 and h4. The real-time current value of the target transmission section A is the sum of the real-time currents of cables d, e, f and g, that is, Figure 2 I in.

[0063] The real-time temperature parameters of each target connection point in the target transmission section can be obtained. The target transmission section includes one or more cables. Each cable in the target transmission section can be used as a target cable, and the real-time temperature parameters of each target cable can be obtained. The real-time temperature parameters refer to the real-time temperature values.

[0064] For example, Figure 2 The real-time temperature parameters of cables d, e, f and g in the target transmission section A can be obtained.

[0065] Regarding step S13, the operating state of the target transmission section is determined according to the real-time electrical parameters of the target transmission section, the real-time temperature parameters of each target cable and / or the real-time temperature parameters of each target connection point, and the operating state includes normal operation and abnormal operation.

[0066] After obtaining the real-time electrical parameters of the target transmission section, the real-time temperature parameters of each target cable, and the real-time temperature parameters of each target connection point, the operation state of the target transmission section is determined according to the real-time electrical parameters of the target transmission section, the real-time temperature parameters of each target cable, and / or the real-time temperature parameters of each target connection point, including [Scheme 1] and [Scheme 2], as follows:

[0067] [Solution 1]

[0068] According to the real-time electrical parameters of the target transmission section and the real-time temperature parameters of each target cable, the real-time resistance of the target transmission section is determined; according to the real-time resistance of the target transmission section and the preset reference resistance, the resistance difference rate of the target transmission section is determined; if the resistance difference rate is greater than the preset resistance difference rate threshold or the real-time temperature parameter of any target connection point is greater than the preset temperature threshold, the target transmission section is operating abnormally.

[0069] Specifically, the real-time resistance value refers to the real-time resistance value, and the real-time resistance value of the target transmission section can be determined according to formula (2), as follows:

[0070]

[0071] Among them, UD is the real-time voltage drop parameter of the target transmission section, I is the real-time current parameter of the target transmission section, α is the constant of temperature and resistance, T0 is the standard temperature (usually 20°), and T is the average temperature value of the target cable in the target transmission section (which can be determined by the real-time temperature parameters of each target cable, such as Figure 2 In the figure, the average temperature value T) of each cable in the target transmission section A is determined by the real-time temperature parameters of d, e, g and h, and R1 is the real-time resistance value of the target transmission section.

[0072] After determining the real-time resistance of the target transmission section, the resistance difference rate of the target transmission section can be determined according to the real-time resistance of the target transmission section and the preset reference resistance. The preset reference resistance can be determined according to the actual situation. For details, refer to formula (3):

[0073] K=|R1-R0|÷R0 formula (3)

[0074] Among them, R1 is the real-time resistance of the target transmission section, R0 is the preset reference resistance, and K is the resistance difference rate.

[0075] If the resistance difference rate of the target transmission section is greater than the preset resistance difference rate threshold, it means that the resistance value of the current target transmission section is too high, and the possible temperature of the target transmission section is also too high, which is prone to accidents; if the real-time temperature parameter of any target connection point is greater than the preset temperature threshold, it means that the temperature of the target connection point is too high, and an accident may occur. Therefore, when the resistance difference rate of the target transmission section is greater than the preset resistance difference rate threshold or the real-time temperature parameter of any target connection point is greater than the preset temperature threshold, it can be considered that the target transmission section is operating abnormally.

[0076] Preferably, in order to save monitoring costs and improve monitoring efficiency, the present application also provides [Scheme 2], which specifically includes step 1 and step 2.

[0077] Step 1: If the real-time temperature parameter of any target connection point is greater than the preset temperature threshold, the target transmission section is operating abnormally.

[0078] Step 2: If the real-time temperature parameter of each target connection point is less than or equal to the preset temperature threshold, the real-time resistance of the target transmission section is determined according to the real-time electrical parameter of the target transmission section and the real-time temperature parameter of each target cable; the resistance difference rate of the target transmission section is determined according to the real-time resistance of the target transmission section and the preset reference resistance; the operating status of the target transmission section is determined according to the resistance difference rate and the preset resistance difference rate threshold.

[0079] It is understandable that in the target transmission section, the location most prone to accidents is the connection point in the target transmission section, that is, the probability of failures in other locations in the target transmission section is low. It is possible to first monitor whether the real-time temperature parameter of any target connection point in the target transmission section is greater than the preset temperature threshold. If so, it means that the target transmission section is operating abnormally, which means that step 2 does not need to be performed, saving monitoring costs and improving monitoring efficiency.

[0080] When the real-time temperature parameter of each target connection point is less than or equal to the preset temperature threshold, the real-time resistance of the target transmission section can be determined according to the real-time electrical parameters of the target transmission section and the real-time temperature parameters of each target cable; the resistance difference rate of the target transmission section can be determined according to the real-time resistance of the target transmission section and the preset reference resistance; the operating status of the target transmission section can be determined according to the resistance difference rate and the preset resistance difference rate threshold. The specific content is similar to that in [Scheme 1], and you can refer to the content in [Scheme 1] for details.

[0081] Since the target transmission segment has two other associated transmission segments, for example, Figure 2 There are also transmission sections B and C associated with the target transmission section A. For transmission sections B and C, steps S11-S13 can still be used to determine the operating status of transmission sections B and C.

[0082] However, in order to improve monitoring efficiency and simplify monitoring steps, the remaining power transmission sections associated with the target power transmission section may also be determined based on the following steps.

[0083] When the target transmission section is operating normally, the remaining transmission sections associated with the target transmission section are determined; the electrical parameters of the remaining transmission sections are obtained; and the operating states of the remaining transmission sections are determined according to the electrical parameters of the target transmission section and the electrical parameters of the remaining transmission sections.

[0084] When the target transmission section is operating normally, it means that the electrical parameters of the target transmission section are also normal. The operating status of the remaining transmission sections can be determined based on the real-time electrical parameters of the target transmission section and the real-time electrical parameters of the remaining transmission sections. Specifically, the real-time current parameters of the target transmission section and the real-time current parameters of the remaining transmission sections can be obtained. When the absolute value of the difference between the real-time current parameters of the target transmission section and the real-time current parameters of the remaining transmission sections is greater than the preset current threshold, the remaining transmission sections are operating abnormally. The preset current threshold is determined according to the actual situation. It can be understood that when the target transmission section is operating normally, only the real-time current parameters of the remaining transmission sections are obtained, and the parameters to be obtained are few, and the judgment method is convenient and fast. Therefore, the monitoring steps are simplified and the monitoring efficiency of the remaining transmission sections is improved.

[0085] In order to ensure the safety of cable operation, when the target transmission section is operating abnormally, an alarm message is sent to the target client for the target client to view. More specifically, if the real-time temperature parameter of the target connection point is less than or equal to the preset temperature threshold, the target connection point can also be obtained and the location of the target connection point can be uploaded to the target client for relevant personnel to view the location of the target connection point, which is convenient for subsequent relevant personnel to conduct inspection and maintenance.

[0086] In summary, the present application determines the target transmission section; obtains the real-time electrical parameters of the target transmission section, the real-time temperature parameters of each target cable in the target transmission section, and the real-time temperature parameters of each target connection point in the target transmission section, the real-time electrical parameters include real-time voltage drop parameters and real-time current parameters; according to the real-time electrical parameters of the target transmission section, the real-time temperature parameters of each target cable and / or the real-time temperature parameters of each target connection point, determines the operating state of the target transmission section, the operating state includes normal operation and abnormal operation. The present application can more accurately judge the operating state of a transmission section with a lower level based on the real-time electrical parameters of the target transmission section, the real-time temperature parameters of each target cable in the target transmission section, and the real-time temperature parameters of each target connection point in the target transmission section, and the present application provides two judgment methods based on the real-time electrical parameters of the target transmission section, the real-time temperature parameters of each target cable in the target transmission section, and the real-time temperature parameters of each target connection point in the target transmission section, which can be selected according to actual conditions, thereby improving the flexibility of judging the operating state of the target transmission section.

[0087] The present application can also determine the operating status of other transmission sections based on the operating status of the target transmission section, with a simple method and high monitoring efficiency.
