At present, a plurality of safety risks exist in data storage and use, and the problem of data leakage is endless, but in a business scene in an electric power system, a plurality of systems are required to cooperate with each other to complete a business process, so that the safety of information transmission and interaction is very important. For example, in the fault repair of power, events such as hotline access, information inquiry and scheduling orders are mainly involved. It is clear that the response time is a key factor of the quality of service of the electric power, and if the response time is too long, the response time is a reason for searching for timeout, and analyzing and taking responsibility. If the information system modifies the log without authorization, which causes the data to change, the reason analysis will be hindered, because there is no real data source, the result analysis also loses reliability, and how to ensure the information is not tampered, the reliability of the information data is the basic requirement of the power, and is also the key point of the power data transmission and data sharing.
Big data is the guarantee of energy system high intelligence, and big data becomes the essential element of production with simple data processing, makes the processing of electric power data become fine granularity, prevents the data disaster, but the shortcoming of this kind of mode processing data is that the supervision is with high costs, inefficiency to can cause revealing of data, and, at present stage, data can not realize data sharing, has caused the data isolated island.

Detailed Description
As shown in fig. 3, characteristics and types of electric power data are analyzed, taking a power plant in the electric power industry as an example, data of a first-zone control area includes SCADA data, PMU data, AGC data, AVC data, unit data, plant-level data, and the like, data of a second-zone non-control area includes fault data, electric energy acquisition data, reservoir automation data, power prediction data, market quotation data, plant-level data, state monitoring data, and the like, and data of a third-zone management information area includes environmental data, seismic data, radiation data, flood prevention data, weather data, anemometer tower data, production management data, overhaul management data, physical safety data, plant-level data, and the like.
As shown in fig. 1, in an electric power data sharing scheme, the electric power data sharing system includes a block chain architecture and a big data center, an electric power data supervision mechanism is composed of an enterprise chain and a supervision chain, a data sharing platform is built, and a point-to-point transaction trust mechanism without third party intervention is formed in a transaction chain manner. Suppose using Yk(n) indicates that there are n kinds of data in the kth zone of the Y-type power plant. The Hash values of the data in the first area and the second area of the electric power are transmitted to the third area through the isolation device, so that the data can meet the anti-tampering requirement, and the safety isolation devices are arranged in the first area, the second area and the third area of the electric power, so that the information can be safely transmitted, and the Hash is realized1+Hash2The two data are hashed, and the hash value calculation process of the data is as follows:
the hash value of the power plant i on the m day is calculated according to the formula
The formula of the hash value of the power plant i in one period T is
The different data storage schemes are as follows:
firstly, the method comprises the following steps: storing the public social data and the Hash value thereof into a database, adding description information into the Hash value, packaging into an abstract block, and then transmitting the information to a platform;
II, secondly: transmitting the data to be supervised and the hash value thereof to a supervision department, and supervising the data by an energy department according to the data management requirement;
thirdly, the method comprises the following steps: and storing the management data and the data source tracing and tamper-proof data into a database, and complying with the management requirements of the private chain.
In the data transmission process, if the data passes through a device or a network, the data has the risk of being copied, and in order to solve the risk, a block chain technical solution is provided, and a point-to-point and de-neutralized exchange based on a public communication chain can ensure that the data is not cached, support anonymous transaction and solve the problems. The invention adopts a mechanism of the abstract directory tree, can reduce the risk and better share and transmit the data.
