Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of block chain, in particular to a system and method for improving the credibility of wind power source end data. BACKGROUND

[0002] In the future, wind power will change from centralized construction to a mixed construction mode of centralization and distribution. A large number of small wind turbines may be spread across vast lands. The management of distributed wind turbines is more complex than that of the original centralized wind turbines. The ownership of distributed wind turbines will be more diversified. Small and medium-sized enterprises or individuals can also build wind turbine generators to obtain power generation benefits by using wind resources.

[0003] In addition, with the construction and operation of distributed wind turbine generators, wind power operators need to mortgage and trade assets due to various reasons, and need to assess and manage the assets. At present, the benefits and operation of wind power can prove the operation of the unit through the power generation data of State Grid Corporation of China. However, if a large number of wind turbine generators are out of the scope of State Grid management, such as wind turbine generators built in industrial parks or owned by individuals, and power generation does not need to be connected to the State Grid, the data of the wind turbine generators will not be verified by an "authoritative" agency, and the valuable power generation benefits cannot be proved. If the wind turbine generator is traded, it will be difficult for the buyer and seller to realize the transaction through a "trusted third party". When wind power assets are traded, it is necessary to assess the existing wind power generation. Small wind turbine generators lack data support from State Grid Corporation of China and need to build their own data systems and prove the credibility of the data. SUMMARY

[0004] In view of the low data credibility of wind turbine generators in the prior art, the present application provides a system and method for improving the credibility of wind power source end data. The wind power source end data is collected by a block chain intelligent terminal and sent to a block chain platform to provide "real" data support for the later transaction of wind turbine generators and improve the credibility of the data.

[0005] To achieve the above purpose, the present application provides the following technical solutions:

[0006] A system for improving the credibility of wind power source end data includes n block chain intelligent terminals and a block chain platform. The n block chain intelligent terminals and the block chain platform form a "trusted" area.

[0007] The n block chain intelligent terminals respectively collect data of each wind power source end, and then upload the data directly to the block chain platform.

[0008] Preferably, the blockchain intelligent terminal is divided into a master and a slave; the master is used to upload the collected data of the wind power source end to the blockchain platform; and the slave is used to verify the data of the wind power source end collected by the master.

[0009] The application also provides a method for improving the credibility of wind power source end data.

[0010] S1: Collecting and storing the data of the wind turbine generator group by using n intelligent terminals respectively.

[0011] S2: Determining one intelligent terminal as a master and the other intelligent terminals as slaves, and uploading the collected data to the blockchain platform by the master.

[0012] Preferably, the blockchain intelligent terminal is internally integrated with a blockchain algorithm, mainly including a blockchain multi-party data consensus algorithm, a blockchain distributed identity algorithm, a blockchain multi-party data collection right competition algorithm and a blockchain on-chain success reward.

[0013] Preferably, the blockchain platform sends the same question to all blockchain intelligent terminals and accepts the feedback signals, and the blockchain intelligent terminal with the correct answer and the shortest time is taken as the master, and the other blockchain intelligent terminals are taken as slaves.

[0014] Preferably, S3 is further included.

[0015] The slave verifies the master, and only after the verification is passed, the master uploads the data to the blockchain platform; if the verification fails, repeat step S2 to determine a new master and slave.

[0016] As described above, compared with the prior art, the application has at least the following beneficial effects:

[0017] The application builds a "credible" data domain through the blockchain intelligent terminal and the blockchain platform, and realizes data non-tamperability. The wind power source head end data is collected by the blockchain intelligent terminal and sent to the blockchain platform, so as to preserve the authenticity of the wind power data, provide "real" data support for the later transaction of the wind turbine generator group, and improve the credibility of the data.

[0020] The application will be described in further detail below with reference to the embodiments and specific working methods. However, it should not be understood that the scope of the above-mentioned subject matter of the application is limited to the following embodiments, and any technology achieved based on the content of the application falls within the scope of the application.

[0021] In the description of the application, it should be understood that the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the application.

[0022] Wind power stations all need to install a control center to remotely monitor all wind turbines and manage the operation of the entire wind farm. Information from each wind turbine and booster station and facilities such as connecting submarine cables needs to be transmitted to the control center for analysis and processing. At the same time, detailed dispatching instructions are issued from here to the end devices. The operation of each unit, power generation data, etc. can be collected through the control center. If there is a single unit that needs to be independently accounted for and traded, the data of the control center is difficult for both parties to the transaction to accept.

[0023] As shown in Figure 1 The application provides a system for improving the credibility of wind power source end data, comprising n blockchain intelligent terminals and a blockchain platform.

[0024] The n blockchain intelligent terminals respectively collect the data of each wind power source end, and then upload the data directly to the blockchain platform.

[0025] The blockchain intelligent terminal and the blockchain platform jointly create a "trusted" area, and in the "trusted" area, the data cannot be tampered with.

[0026] The blockchain intelligent terminal has a blockchain algorithm integrated therein, mainly including a blockchain multi-party data consensus algorithm, a blockchain distributed identity algorithm, a blockchain multi-party data collection right competition algorithm, a blockchain on-chain success reward, etc., such as PBFT and Raft.

[0027] In this embodiment, each blockchain intelligent terminal can collect the data of each wind turbine through a data bus. Each intelligent terminal will determine one intelligent terminal as a master according to the blockchain data collection right competition algorithm, but other intelligent terminals will also collect data as slaves.

[0028] In this embodiment, the slave mainly plays a verification role, supervises the master, and prevents it from doing evil, such as the master malfunctioning and causing inaccurate collected data. After the master data is verified, it is sent to the blockchain platform.

[0029] The blockchain platform will adopt an internal distributed accounting mechanism, and will perform multi-party consensus accounting on the data and save it in a chain manner to prevent node data from being tampered with.

[0030] By using the blockchain platform and the blockchain intelligent terminal, the wind power source end data is sent to the blockchain platform, the feature of data being unalterable is realized, and a "trusted" data domain is helped to be realized.

[0031] By using the blockchain technology, the wind power data is kept true, and "true" data support can be provided for the later transaction of the wind turbine generator set.

[0032] As shown in Figure 2 The application also provides a method for improving the credibility of wind power source end data, which specifically comprises the following steps:

[0033] S1: n intelligent terminals are used to collect and store the data of the wind turbine generator set respectively.

[0034] In this embodiment, a blockchain algorithm is arranged in each intelligent terminal, mainly including a blockchain multi-party data consensus algorithm, a blockchain distributed identity algorithm, a blockchain multi-party data collection right competition algorithm, and a blockchain on-chain success reward, etc.

[0035] S2: A blockchain multi-party data collection right competition algorithm is used to determine one intelligent terminal as a master and the other intelligent terminals as slaves, and the master uploads the collected data to the blockchain platform.

[0036] In this embodiment, the blockchain multi-party data collection right competition algorithm is that the platform sends the same question (with a correct answer preset) to all intelligent terminals and accepts the feedback signal, and the intelligent terminal with the correct answer and the shortest time is determined as the master, and the other intelligent terminals are determined as slaves, so that the data collection speed is improved and the work efficiency is improved.

[0037] S3: In this embodiment, in order to prevent the master from malfunctioning and causing problems in the collected data, the slave verifies the master before the master uploads the collected data, and only after the verification is passed, the master can upload the data to the blockchain platform.

[0038] For example, the data collected by the host and all slaves are compared, the data of the host should be consistent with the distribution of the data of all slaves, and can fluctuate within a preset range, thereby proving the correctness of the data collected by the host, and uploading the data to the blockchain platform; if the data collected by the host deviates from the distribution of the data of the slaves (fluctuation exceeds the preset range), it means that the host has a problem and cannot collect the data in the host. At this time, the host is marked as "invalid", and steps S2-S3 are repeated to determine a new host, so as to avoid interruption of data collection and improve work efficiency.

[0039] Those skilled in the art can understand that the above-mentioned embodiments are specific examples for implementing the present application, and in actual application, various changes can be made in form and details without departing from the spirit and scope of the present application.
