Description

Fan fault early warning system and method
Technical Field
The invention relates to the technical field of wind driven generators, in particular to a fan fault early warning system and method.
Background
The fan fault early warning refers to collecting real-time data of a fan, and then processing the real-time data by adopting a mechanism algorithm, a machine learning algorithm and other methods, so that the probability of the fan failing in a future period of time is obtained, and further, the operation and maintenance strategy adopted at the present or a future time point is determined. The fault early warning is a key technology for realizing the predictability operation and maintenance of the wind driven generator, and is beneficial to reducing the unplanned shutdown times of the wind turbine, thereby obviously reducing the operation and maintenance cost of wind power generation and improving the full life cycle yield of the wind power generation.
At present, a single-machine application program is usually developed for fan fault early warning, a fault early warning algorithm is integrated in the program, and the program is installed and deployed on a local computer of a wind power plant booster station or a local computer of a certain remote centralized monitoring center. The characteristics of this deployment can be summarized as follows: centralizing monolithic applications and localized deployment. In practical applications, when a company has tens of wind farms or a plurality of remote centralized monitoring centers, these features bring about the following disadvantages.
First, the process of continuous development of fault warning systems becomes unmanageable. The fault early warning algorithm is continuously, rapidly iterated and newly added, the services for developing and testing the algorithms are generally in the headquarters of companies or regional headquarters, and meanwhile, operation and maintenance personnel in the local wind power plant can also carry out algorithm testing and trial operation. However, since the continuous development process of the fault early warning system is based on localized deployment and centralized application programs, these algorithms become fragmented and cannot be uniformly managed and used finally along with continuous iteration of each local system.
Second, such an approach can make deployment of the fault warning system costly and extremely inefficient. Because the iteration and the addition of the fault early warning algorithm are developed at the company headquarters or the regional headquarters level, the fault early warning algorithm can be applied to all the fans, but because a centralized single application program is adopted, the improved and the added algorithms are integrated into each locally deployed fault early warning centralized single program and need to be developed, tested and deployed again, so that the development of the fault early warning algorithm and the development and the change of the corresponding programs are extremely inefficient, and the development, the test and the deployment of the algorithms and the programs can be managed in a standardized way only by investing very high labor cost and management cost.
In summary, how to more conveniently and effectively develop, test and deploy a fault early warning algorithm is a technical problem that needs to be solved urgently by those skilled in the art at present.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a fan failure early warning system according to the present invention, where the fan failure early warning system may include:
the N wind farm local end systems 10 are all used for uploading detection data of each fan in the wind farm local end system 10;
the system comprises M regional end centralized control center systems 20, wherein each regional end centralized control center system 20 comprises an information center system 21, a fault early warning container service system 22 and a regional end wind power plant operation and maintenance system 23; wherein M and N are positive integers;
the information center system 21 is used for receiving and storing the detection data uploaded by one or more wind power plant local end systems 10;
the fault early warning container service system 22 is configured to, when it is determined that detection data of any one of the fans stored in the information center system 21 is updated, encapsulate, based on the type of the fan, each early warning algorithm that is preset in an early warning algorithm code base and allowed to be applied to the fan of the type and configuration information on which each early warning algorithm depends, obtain a container mirror image corresponding to the type of the fan, and construct and execute a container instance for the fan based on the container mirror image;
the regional end wind power plant operation and maintenance system 23 is used for receiving each early warning result obtained by the fault early warning container service system 22 executing each container instance, and outputting corresponding operation and maintenance information based on each early warning result;
and the cloud algorithm updating system 33 is used for updating the algorithm of the early warning algorithm code base in each regional terminal centralized control center system 20.
Specifically, the value of N generally depends on the number of the actual wind farm, and each wind farm local end system 10 periodically performs detection data of each fan in the wind farm local end system 10, specifically, in the scheme of the present application, the detection data is uploaded to the area end corresponding to the wind farm local end.
It should be noted that, one regional end may receive data uploaded by one or more local wind farm ends, that is, for an information hub system 21 in any one regional end centralized control center system 20, the information hub system 21 may receive and store detection data uploaded by one or more local wind farm end systems 10, and in practical application, one information hub system 21 generally receives and stores detection data uploaded by a plurality of local wind farm end systems 10.
In addition, it should be noted that the number of the local end systems 10 of the wind farm corresponding to different regional end centralized control center systems 20 may be different, for example, in a specific occasion, one regional end centralized control center system 20 may receive data uploaded by 3 local end systems 10 of the wind farm, and another regional end centralized control center system 20 may receive data uploaded by 5 local end systems 10 of the wind farm, for example.
The specific configuration of each wind farm local end system 10 may also be set and adjusted according to actual needs, for example, in an embodiment of the present invention, each wind farm local end system 10 may include:
p data acquisition ends, wherein each data acquisition end corresponds to one fan and is used for acquiring the detection data of the fan according to a preset period; wherein, P is a positive integer;
the wind power plant local SCADA system is used for sending the data of each data acquisition end to the communication management machine;
and the communication management machine is used for uploading the detection data of each fan of the wind farm local end system 10 to the information central system 21 of the regional end centralized control central system 20 corresponding to the wind farm local end system 10 for storage.
This embodiment is also the more common configuration of the wind farm local end system 10. It can be understood that, in different wind farm local end systems 10, the number of data acquisition ends may be different, that is, the value of P in different wind farm local end systems 10 may be different. The specific form of the data acquisition end can also be selected according to actual needs, for example, the specific form can be a common PLC (Programmable Logic Controller). In the specific embodiment of fig. 2 of the present application, each data acquisition end is a fan PLC11, for example, the fan collects real-time sensor data of the fan to the PLC corresponding to the fan every 1s, that is, the preset period in this example is 1s, and of course, in other specific occasions, the value of the preset period can be adaptively adjusted as needed.
A local SCADA (Supervisory control and data acquisition) system of a wind power plant is a widely applied data acquisition and monitoring control system, and is convenient for implementation of schemes. The communication manager 13 may upload the detection data of each fan of the wind farm local end system 10 to the information center system 21 of the regional end centralized control center system 20 corresponding to the wind farm local end system 10 for storage, and specifically, in this embodiment, the communication manager 13 may upload the data uploaded by the wind farm local SCADA system 12 by relaying.
Further, in an embodiment of the present invention, referring to fig. 2, each wind farm local end system 10 may further include:
a data encryption system 14 for encrypting the data uploaded by the communication manager 13;
correspondingly, each regional end centralized control center system 20 further includes:
and the data decryption system 201 is used for decrypting the received data and storing the decrypted data to the information center system 21.
In this embodiment, the data is encrypted and then uploaded to the regional end centralized control center system 20, which is beneficial to improving the security of data transmission. In addition, in the embodiment of fig. 2, a firewall 202 and a forward isolation system 203 are further disposed in the regional end centralized control center system 20, so as to further enhance data security.
The regional end centralized control center system 20 of the present application is generally disposed at a regional headquarters of a region, and is configured to manage wind farms in the region, and each regional end centralized control center system 20 includes an information center system 21, a fault early warning container service system 22, and a regional end wind farm operation and maintenance system 23. For example, in the embodiment of fig. 2, 3 wind farm local end systems 10 are shown, and it can be understood that internal configurations of the wind farm local end systems 10 may be the same or different, and the functional requirements of the present application may be met, without affecting the implementation of the present application.
When the detection data of any fan stored in the information center system 21 is updated, the fault-early-warning container service system 22 constructs and executes a container instance corresponding to the fan based on the content of the detection data.
Specifically, the early warning algorithm code base described in the present application includes a plurality of fault early warning algorithms, for example, 70 fan fault early warning algorithms are developed by a worker in a manner of adopting a mechanism algorithm, a machine learning algorithm, and the like, and the early warning algorithm code base of the present application includes 70 fault early warning algorithms. It should be noted that, for a specific fault early warning algorithm, the fault early warning algorithm may only be applicable to one fan product, and may also be applicable to multiple fan products. For example, one of the 70 fault warning algorithms is a fan yaw speed anomaly warning algorithm, which is suitable for two fan products, and the other fault warning algorithm can be suitable for three fan products, for example.
When the fault early warning container service system 22 determines that the detection data of any one of the fans stored in the information center system 21 is updated, each of the early warning algorithms allowed to be applied to the fan of the type and the configuration information on which each of the early warning algorithms depends, which are preset in the early warning algorithm code library, can be encapsulated based on the type of the fan, so as to obtain a container mirror image corresponding to the type of the fan.
For example, a certain fault early warning container service system 22 receives data uploaded by two wind power plants, the two wind power plants include 6 wind turbine products in total, the number of wind turbines of each wind turbine product is 5, that is, the two wind power plants have 6 wind turbine types and 30 wind turbines in total. The fault-advance container service system 22 may generate 6 container mirrors. For example, for a type a fan, 46 early warning algorithms among 70 fault early warning algorithms may be applied to the type a fan, and then 46 algorithms are included in a container mirror image corresponding to the type a fan, and during packaging, configuration information on which the 46 early warning algorithms depend needs to be packaged, where the configuration information may specifically include system configuration data, environment data, runtime database data, and the like. That is, the container mirror image described in this application refers to: and (3) packaging the fault early warning algorithm cluster mirror image required by one fan product, and simultaneously packaging all necessary information such as system configuration, environment, operation library and the like which are required by the algorithms to be executed, namely forming a container mirror image which is a standard container for packaging all early warning algorithms of one fan product.
It is understood that when a container image is packaged, the type of fan that can be used by the container image is also determined. After the container mirror image is obtained, based on the container mirror image, a container instance for the fan can be constructed and executed, where the container instance refers to a computer process in which the container mirror image is used for fault early warning of one fan, that is, when detection data of any fan stored in the information center system 21 is updated, the detection data of the fan is input to the corresponding container instance, so that an early warning result can be obtained. In the foregoing example, there are 6 wind turbine types in two wind farms, and 30 wind turbines, it will be appreciated that the fault-early-warning container service system 22 can generate 6 container images, and 5 container instances can be constructed based on each container image.
Further, it should be noted that the fault-advance container service system 22 may construct multiple container instances, but not necessarily simultaneously. For example, in fig. 2, N wind farm local end systems 10 upload data at a frequency of 1Hz, and each of the wind farm a local end system 10 and the wind farm B local end system 10 uploads data to the regional end centralized control center system I, in this 1s, the detection data of each wind turbine may arrive sequentially rather than simultaneously. For example, there are 30 fans in the wind farm a and the wind farm B, for example, if the detection data of the fan No. 1 in the 0.3s of the 1s is updated, the fault early warning container service system 22 will construct a container example of the detection data corresponding to the fan No. 1, and if the detection data of the fan No. 0.35s, the fan No. 2 and the fan No. 7 in the 1s are updated, the fault early warning container service system 22 will construct a container example of the detection data corresponding to the fan No. 2 and a container example of the detection data corresponding to the fan No. 7. Usually, if the detection data of 30 fans in 1s are all updated, the fault warning container service system 22 constructs 30 container instances in total.
The fault-early-warning container service system 22 executes each constructed container instance, and then obtains the execution result of each container instance, that is, the early-warning result. For example, 26 algorithms are included for a certain container example, and each algorithm can obtain a judgment value indicating whether to warn or not.
The operation and maintenance system 23 of the regional wind farm can summarize the early warning results, and output corresponding operation and maintenance information based on each early warning result, and generally, can output the operation and maintenance information to the cloud, that is, in a specific embodiment of the present invention,
the operation and maintenance system 23 for the regional wind farm may be specifically configured to:
receiving each early warning result obtained by executing each container instance by the fault early warning container service system 22, and outputting corresponding operation and maintenance information to the cloud operation and maintenance management system based on each early warning result;
and the cloud operation and maintenance management system is used for carrying out corresponding operation and maintenance operation based on the operation and maintenance information.
In addition, the area end may also directly output the early warning result to the cloud end in addition to outputting the operation and maintenance information, that is, in a specific embodiment of the present invention, the method may further include:
and the cloud centralized monitoring system is used for receiving and displaying each early warning result obtained by executing each container instance by the fault early warning container service system 22, so that the early warning condition of each fan can be conveniently mastered in real time through the cloud. In the embodiment of fig. 2 of the present application, a cloud operation and maintenance management system 31 and a cloud centralized monitoring system 32 are disposed at the cloud.
The cloud algorithm updating system 33 is configured to perform algorithm updating on the early warning algorithm code base in each regional end centralized control center system 20, that is, the algorithm is developed at the cloud end, and the regional end only needs to receive the algorithm sent by the cloud end to update the early warning algorithm code base at the regional end, so that the operation of the regional end staff is very simple and convenient, and the technical requirements on the regional end staff are low.
It should be noted that, compared with the case where the container instance is deployed in the cloud, the case where the container instance is run at each region end is generally suitable for the occasion where the data size is light. That is, for a company with a particularly large number of partial fans, the cloud may be used to execute each container instance, whereas for some light-weight companies, since the data size is not particularly large, if the cloud is used to execute each container instance, the cost is high, and therefore, a distributed deployment scheme is adopted, that is, M regional end centralized control center systems 20 are used to execute each container instance, which is beneficial to reducing the cost, and resources of each regional end centralized control center system 20 can be effectively utilized. Meanwhile, due to the fact that algorithm development is carried out at the cloud end, the scheme of the application still has the advantages that integration, testing and deployment of a localization program do not need to be considered in the traditional scheme, and the problems that version fragmentation is caused due to multi-end maintenance in the traditional scheme and unified management and use cannot be achieved are solved.
In a specific implementation of the fault warning container service system 22, data may be obtained in a subscription manner, and in a specific implementation of the present invention, the fault warning container service system 22 may be specifically configured to:
when triggered by the update log, it is determined that the detection data of any one of the fans stored in the information hub system 21 is updated, the detection data of the fan is acquired from the information hub system 21 in a subscription manner, each pre-warning algorithm allowed to be applied to the fan of the type and configuration information on which each pre-warning algorithm depends are set in the pre-warning algorithm code base and packaged based on the type of the fan, a container mirror image corresponding to the type of the fan is obtained, and a container instance for the fan is constructed and executed based on the container mirror image.
In this embodiment, the fault early warning container service system 22 determines that the detection data of a certain fan is updated through the log, and then acquires the detection data of the certain fan from the information hub system 21 in a subscription manner, which is also an embodiment convenient for application.
In an embodiment of the present invention, the cloud algorithm updating system 33 may further be configured to:
when a gray level updating instruction is received, the target algorithm in the early warning algorithm code base in each regional end centralized control center system 20 is updated, and the target algorithm before updating is reserved.
In this embodiment, when the target algorithm in the early warning algorithm code library in each regional end centralized control center system 20 is updated, the target algorithm before updating is retained, so that two or more versions of a certain algorithm can exist, a gray level test is realized, and the test requirements of the algorithm performance in some occasions can be met.
By applying the technical scheme provided by the embodiment of the invention, the detection data of each fan in the N wind power plant local end systems 10 are uploaded, specifically, M regional end centralized control center systems 20 are arranged, and each regional end centralized control center system 20 comprises an information center system 21, a fault early warning container service system 22 and a regional end wind power plant operation and maintenance system 23. The information center system 21 may receive and store the detection data uploaded by one or more wind farm local end systems 10. Specifically, in the scheme of the application, a container service architecture is adopted, and the operation examples of the early warning algorithm cluster required by the single fan are deployed in the containers of the distributed system, so that the fan fault early warning service logic and the bottom layer of the information system are maximally separated, and the bottom layer of the information system executed by the container examples is implemented by a unified information system architecture, namely the distributed system architecture based on container arrangement. Specifically, when determining that the detection data of any one of the fans stored in the information center system 21 is updated, the fault early-warning container service system 22 packages each early-warning algorithm allowed to be applied to the fan of the type and the configuration information on which each early-warning algorithm depends, which are preset in the early-warning algorithm code base, based on the type of the fan, obtains a container mirror image corresponding to the type of the fan, and constructs and executes a container instance for the fan based on the container mirror image. And, the algorithm updating in the early warning algorithm code base is realized by the cloud algorithm updating system 33. It can be seen that, when the algorithm is developed, tested and deployed, the worker only needs to pay attention to the fault early warning algorithm, that is, only needs to adjust the early warning algorithm code library of each regional end centralized control center system 20 through the cloud, and does not need to consider the integration, testing and deployment of the localization program as in the conventional scheme. In addition, the container instances are run through the M regional end centralized control center systems 20, and compared with running through a cloud end, the system is generally suitable for occasions with light data size, and is lower in cost.
