Description

Technical Field

[0001] The present application relates to the technical field of fault location, and in particular to a method and system for locating a collector line fault for wind power generation. Background Art

[0002] Wind power generation is an important part of renewable energy generation, and the safe and stable operation of its collector lines has a vital impact on the overall operational efficiency of wind farms. However, due to the complex operating environment of wind farm collector lines, which are susceptible to multiple factors such as storms, icing, lightning strikes, and line aging, collector line failures occur frequently, bringing great challenges to the operation and maintenance of wind farms.

[0003] At present, the data of the collector line is usually displayed in the form of text and charts, which lacks intuitiveness and is not convenient for managers to quickly locate and deal with problems. At the same time, when a fault occurs, the system usually simply lists the faulty line nodes without sorting the fault information according to the urgency and importance of the fault. Existing technologies usually use rule-based systems to identify faults and trigger alarms by setting specific thresholds and conditions.

[0004] The existing system can reduce the burden of line operation and maintenance personnel to a certain extent and realize the rapid discovery and response of faults. However, it fails to effectively integrate the dynamic location of the current collector line fault to dynamically generate the priority location of maintenance, resulting in the operation and maintenance personnel often taking random paths during the maintenance process and failing to quickly repair more important or more influential line faults. Summary of the invention

[0005] In order to solve at least one of the above technical problems, the present application provides a collector line fault location method and system for wind power generation.

According to the maintenance priority, the target maintenance line node and its fault location information are determined, and then the optimal maintenance route is determined in combination with the maintenance line location.

[0025] The following is combined with Figure 1 To Attachment Figure 3 This application is described in further detail.

After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article, unless otherwise specified, generally means that the associated objects before and after are in an "or" relationship.

[0029] The embodiments of the present application are further described in detail below in conjunction with the drawings in the specification.

[0030] The embodiment of the present application provides a method for locating faults in a collector line for wind power generation, which is executed by an electronic device, which can be a server or a terminal device, wherein the server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides cloud computing services. The terminal device can be a smart phone, a tablet computer, a laptop computer, a desktop computer, etc., but is not limited thereto. The terminal device and the server can be directly or indirectly connected via wired or wireless communication, which is not limited in the embodiment of the present application. Figure 1 As shown, the method includes: Step S10: Collecting real-time power transmission data.

[0031] The real-time power transmission data includes line transmission data of nodes at different positions of different collector lines and line node positions.

[0032] For the embodiments of the present application, different collector lines refer to multiple independent or associated path lines in the power system for collecting and transmitting electric energy, and different position nodes refer to key points or positions set on these lines for monitoring and recording the power transmission status. Line transmission data refers to specific power parameters collected through these nodes, such as voltage, current, power, temperature, sag, etc. The line node position is used to indicate the specific geographical location of these key monitoring points in the power system or the relative position on the line.

[0033] In the embodiment of the present application, drone inspection technology is used to collect real-time power transmission data. Specifically, the drone flies or moves along the power collection line, uses the sensors or cameras on board to capture the power parameters and image information at the line nodes, and then transmits the data to the ground station or central monitoring center for analysis through wireless communication.

[0034] Step S11: establishing and updating the three-dimensional line model of the power collection line in real time according to the real-time power transmission data.

[0035] For the embodiment of the present application, the line three-dimensional model is a virtual model with a three-dimensional and spatial sense generated in a computer based on the actual structure and layout of the collector line using three-dimensional modeling technology. According to real-time power transmission data, the line three-dimensional model is continuously adjusted and corrected to reflect the actual state of the collector line.

[0036] In the embodiment of the present application, BIM technology is used to construct a three-dimensional model of the route, including but not limited to BIM technology. The model construction technology can be selected and applied according to one's own needs, and no further limitations are given here.

[0037] Step S12: Monitor the real-time power transmission data to determine whether there is a faulty collector line. If so, mark the collector line corresponding to the real-time power transmission data in the line three-dimensional model, and determine the overall position layout of the collector line, the fault position layout of the fault line, and the maintenance line position for maintenance personnel to go to the fault position layout based on the marked line three-dimensional model.

[0038] Step S13: Perform location scoring according to the fault location layout, and perform fault scoring on the location priority obtained by the scoring through a preset fault weighted calculation model to obtain a maintenance priority.

[0039] For the embodiment of the present application, clustering behavior parameters of a preset clustering algorithm are obtained, and the clustering behavior parameters include a minimum density threshold and a standard search radius. The preset clustering algorithm is run according to the clustering behavior parameters to cluster the faulty lines, and line range nodes that meet the minimum density threshold and are within the standard search radius are generated. Several faulty lines that are not within the line range are marked as independent line nodes, and several line range nodes are scored in order from high to low to obtain node scores corresponding to the line range nodes. The range node priority corresponding to the line range node is determined according to the node score, and the adjacent target nodes are obtained in turn according to the range node priority, and the adjacent target nodes are set as nodes of the next level position priority of the line range to generate a position priority.

[0040] In an embodiment of the present application, the preset clustering algorithm is the CLIQUE algorithm, which is a grid-based clustering algorithm for discovering density clusters in a subspace. When determining the preset parameters of the CLIQUE algorithm, namely the minimum density threshold and the search radius, it is necessary to consider the characteristics of the data set, such as the distribution density of data points and the dimension of the data space. The minimum density threshold is used to define whether a grid is dense, and the search radius is used to determine the size of the grid.

[0041] Specifically, the type of the target node adjacent to the clustering area is determined according to the order of the range node priority. If the type of the target node adjacent to the clustering area is a line range node, the line range node is set as a node of the next level of position priority, and the line range node is updated to the highest priority of the range node priority. If the node type is an independent line node, the nearest line range node and the independent line node are simultaneously set as nodes of the next level of position priority, and the line range node is updated to the highest priority of the range node priority. If all line range nodes are set with position priority, based on the position of the line range node with the lowest range node priority, the nearest independent line node for which the position priority is not set is obtained, and according to the position distance of several independent line nodes, the position priority of the independent line nodes for which the position priority is not set is set in sequence from near to far.

[0042] In addition, in an embodiment of the present application, it is determined whether there are two types of nodes in the location priority. If not, the node is passed through a preset fault weighted calculation model to obtain a fault score. If so, the fault scores of the line range nodes and independent line nodes at the same location priority are obtained, and the maintenance priority of the faulty line is updated in order of the fault scores from high to low.

[0043] Step S14: determining a target maintenance line node and fault location information corresponding to the target maintenance line node according to the maintenance priority.

[0044] Step S15: Determine the optimal maintenance route of the target maintenance line node according to the fault location information and the maintenance line position.

[0045] In the embodiment of the present application, the power transmission data and location information of the collector line are collected in real time, providing an accurate data basis for subsequent fault location. Then, a three-dimensional model of the line is established and updated in real time, so that the line status is visualized and easy to understand intuitively. The real-time power transmission data is monitored, and once a fault is found, it is immediately marked in the three-dimensional model, and the overall and specific location layout of the fault line is determined. At the same time, combined with the maintenance line location of the maintenance personnel to the fault location, a clear guide is provided for subsequent maintenance work. The fault location is scored, and the maintenance priority is obtained through the fault weighted calculation model. The interaction of this step is that the importance, urgency and relevance of the fault location are comprehensively considered, so that the maintenance work can be carried out in order according to the priority, optimize resource allocation, and improve maintenance efficiency. According to the maintenance priority, the target maintenance line node and its fault location information are determined, and then the optimal maintenance route is determined in combination with the maintenance line location. Combining fault location with maintenance route planning ensures that maintenance personnel can reach the fault point in the shortest time and the best path, further shortening the fault repair time and improving the maintenance efficiency of the collector line.

[0046] Furthermore, the method also includes: assigning a first score to each level of the fault type of the fault line, the larger the first assigned score, the higher the fault level; assigning a second score to each level of the fault impact range of the fault line node, the larger the second assigned score, the larger the fault impact range, the fault impact range is the radiation area of ​​the abnormal impact on other collector lines around the fault node position after a fault occurs at the fault node position corresponding to the fault line; assigning a third score to each level of the fault duration of the fault line, the larger the third score, the longer the fault duration; establishing a fault weighted calculation model based on the first score, the second score and the third score, the fault weighted calculation model performs weighted calculation by obtaining the fault type, impact range and fault duration of the fault line, and the calculation result is the fault score.

[0047] In addition, in the present application, the job type of the operation and maintenance personnel who is closest to the faulty line is obtained, and according to the job type of the operation and maintenance personnel, the fault area nodes and independent nodes with matching fault types are marked in the simulated cabinet display system. The operation and maintenance personnel can adjust the optimal maintenance route according to the marks in the simulated cabinet display system, and give priority to going to the marked nodes, thereby reducing the ineffective movement of the operation and maintenance personnel and improving the professionalism and efficiency of fault handling.

[0048] Furthermore, establishing and updating the three-dimensional line model of the collector line in real time according to the real-time power transmission data also includes: judging whether the collector line is displaced according to the three-dimensional line model, and generating line displacement alarm information if there is any displacement.
