If the first and second are described for the purpose of distinguishing technical features, they are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated or implicitly indicating the precedence of the technical features indicated.
In the description of the present invention, unless otherwise explicitly limited, terms such as arrangement, installation, connection and the like should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific contents of the technical solutions.
With the rapid development of the power grid system, the power grid system is divided into a production control area and a management information area according to the characteristics of the power grid system. The production control area is divided into a control area (a safety area I) and a non-control area (a safety area II), and the information management area is divided into a production management area (a safety area III) and a management information area (a safety area IV). Different security zones determine different security protection requirements. At present, data cross-region synchronous transmission and storage in a power grid system are realized through a cross-region network. For example, in the related art, in order to ensure the security and accuracy of information acquisition by a scheduling production management system, a lightning monitoring system, a statistical form system, and the like in the security zone iii, it is necessary to establish connection with a system corresponding to the security zone i through a cross-regional network and perform data synchronization.
However, due to the diversified development of the power grid system, the diversity of the automation system, the diversity of the data standards, the delay of the information content, and the like, the power grid cross-regional network is difficult to transmit, analyze and store data. With the increasing number of target services of the power grid, uniform data synchronization cache is more and more important. Therefore, a new information cross-region method is urgently needed for the power grid system at present.
For the problems in the related art, referring to fig. 1, an embodiment of the present invention provides a power grid monitoring system information cross-region method based on a synchronous cache. The method is applied to a server, and an execution subject is taken as an example for explanation, and the method comprises the following steps:
101. acquiring function information of a plurality of different historical time periods in a first safety zone system of the power distribution network, and encrypting the function information to obtain cross-zone information;
102. determining a data structure matched with the trans-regional information according to the data type of the trans-regional information, and converting the trans-regional information into cache information in the second security area system according to the data structure matched with the trans-regional information;
103. constructing a cache database consisting of cache information according to the data structure corresponding to the cache information;
104. and if the target service instruction generated by the second secure area system is detected, acquiring corresponding function information according to the target service instruction, and transmitting the function information to the client specified by the target service instruction.
In step 101, the distribution network refers to an electric power network that receives electric energy from a transmission network or a regional power plant and distributes the electric energy to various users locally or step by step according to voltage through a distribution facility. The power distribution network is composed of overhead lines, cables, towers, distribution transformers, isolating switches, reactive power compensators, a plurality of accessory facilities and the like, and plays a role in distributing electric energy in the power network. The power grid system is divided into a production control area and a management information area, the production control area is divided into a control area (a safety area I) and a non-control area (a safety area II), and the information management area is divided into a production management area (a safety area III) and a management information area (a safety area IV).
Note that the first secure area system is a control area (secure area i). The functional information refers to the running state information of the power grid monitoring system, and specifically includes power distribution network load information, power distribution network power supply information and power distribution network voltage regulation and control information. In consideration of confidentiality of information transmission in different security zones, leakage of sensitive information inside the functional information is avoided, and encryption operation needs to be performed on the functional information, so that cross-zone information is obtained.
In step 102, the data structure refers to a collection of data elements that have one or more specific relationships with each other, and is also a way for a computer to store and organize data. Data is classified according to data structure, data with the same data structure is classified into one category, and the data in the same category is collectively called data type. A data type is a collection of values and a collection of operations defined on this set of values. The data type is used to indicate the attribution of a piece of data in a data classification, which is an attribute of the data. Therefore, the data structure matched with the data type of the cross-area information can be determined according to the data type of the cross-area information.
In addition, the second secure area system is a production management area (secure area iii). In consideration of cross-region transmission of information, the cross-region information needs to be classified in the second security region according to the data structure of the cross-region information, so that the cross-region information is converted into cache information.
In step 103, the cache information is classified according to the data structure corresponding to the cache information, and each class corresponds to a database corresponding to the cache information data structure, so as to construct a cache database composed of the cache information.
The method provided by the embodiment of the invention can realize cross-region transmission of data information, can ensure the confidentiality of the information in the transmission process, and can carry out data acquisition, extraction and monitoring control on the running state of the power distribution network, thereby improving the data transmission speed between the first safety region and the second safety region and being convenient for quickly finding and responding to the abnormal condition generated in the running process of the power distribution network. By constructing the cache database consisting of the cache information, the connection stability and the response speed between the cache database and the client are improved, the change and abnormal conditions of the trans-regional information can be fed back to the client quickly and accurately, the synchronism and extraction convenience of the trans-regional information of the power distribution network are improved, and the timeliness of information transmission is ensured.
In combination with the above embodiments, in some embodiments, the function information includes performance information, performance level information, collection time information, and location information. Specifically, the performance information is performance information of the distribution network voltage regulation and control unit and the distribution network load condition statistical unit. The performance grade information is the voltage grade of the power distribution network voltage regulation and control unit. Distribution network voltage class refers to the series of nominal voltage values used in a distribution network. The voltage grade of the power distribution network determines the insulation level required by the power supply equipment, and directly influences the electric energy loss and the voltage loss. The acquisition time information is acquisition time for acquiring distribution network load information, distribution network power supply information and distribution network voltage regulation and control information. The position information is the position location of the collected load information of the power distribution network, the power supply information of the power distribution network and the voltage regulation and control information of the power distribution network.
According to the method provided by the embodiment of the invention, the functional information is refined in four aspects of performance, performance grade, acquisition time and position, so that the functional information of the structure can effectively reflect the operation condition of the current power distribution network, the performance query and the data extraction can be rapidly carried out, and the timeliness of the transmission of the cross-region information of the power distribution network is improved.
In combination with the above embodiments, in some embodiments, the cache database includes a file transfer protocol FTP database, a relational database, and a time series database. In particular, the file transfer protocol FTP database is a file transfer protocol database. The FTP file transfer protocol is used for internet bidirectional transmission, and controls a file downloading space to copy files from a local computer or a local uploading file to a space on a server in the server.
In addition, the relational database is a database established on the basis of a relational database model, processes data in the database by using concepts and methods such as set algebra and the like, and is also a table organized into a group with formal descriptive properties. The essence of this form of table is a special collection of loaded data items, the data in these tables can be accessed or recalled in many different ways without the need to reorganize the database tables. The definition of a relational database results in a table of metadata or in a formal description of tables, columns, ranges, and constraints. Each table (sometimes referred to as a relationship) contains one or more data categories represented by columns. Each row contains a unique data entity, which is a category defined by the columns. Currently, the mainstream relational databases are oracle (distributed database), db2 (distributed database), sqlserver (distributed client/server computing based database), sybase (client/server architecture based database), mysql (structured query language database), and the like. The cache database can select a corresponding relational database according to the actual requirement and the interface attribute of the client.
The time-series database is mainly used for processing time-tagged (time-series) data, and the time-tagged data is also referred to as time-series data. The storage and processing of time series big data are often processed in a relational database mode, but the relational database cannot perform efficient storage and data query due to the inherent disadvantages of the relational database. The time sequence big data solution enables the time sequence big data to be efficiently stored and quickly process the mass time sequence big data by using a special storage mode, and is an important technology for solving the mass data processing.
For example, if the client is a power distribution network load condition statistical unit, the power distribution network load condition function information is acquired, encryption and caching operations are sequentially performed to obtain power distribution network load condition cache information, and the power distribution network load condition cache information is stored in the time sequence database. The power distribution network load condition statistical unit can quickly inquire corresponding cache information through the time sequence database, so that the real-time statistics and monitoring functions of the power distribution network load condition statistical unit are realized, and the conditions that the information is delayed and the updating is not timely in the power distribution network load condition statistics are avoided.
According to the method provided by the embodiment of the invention, the cache database can provide the cache information with different formats according to the target service instructions with different categories, so that the processing time of the second safety zone system on the cache information is shortened, and the speed of the second safety zone system for acquiring the cache information is improved. The time sequence database adopts a special data storage mode, and the processing capacity of the statistical information of the load condition of the power distribution network is greatly improved. Compared with a relational database, the superior query performance of the time sequence function is far superior to that of the relational database, the storage space of the time sequence database is halved, and the query speed is greatly improved.
With reference to the content of the foregoing embodiments, in some embodiments, the cache database periodically obtains new cache information through a preset channel set, and updates the cache database, where the preset channel set includes a secure shell SSH channel, a network transport protocol family IPSec channel, and a secure socket protocol SSL channel.
In particular, the secure shell SSH is a security protocol built on an application layer basis. The secure shell SSH is a relatively reliable protocol that is dedicated to providing security for telnet sessions and other web services. The information leakage problem in the remote management process can be effectively prevented by utilizing the SSH protocol of the security shell. The internet protocol transport family IPSec is a protocol packet that protects the internet protocol transport protocol family (a collection of interrelated protocols) by encrypting and authenticating packets of the IP protocol. The secure socket protocol SSL is a secure protocol for providing security and data integrity for network communication, and can ensure that data is not intercepted and eavesdropped during network transmission by using a data encryption technology.
According to the method provided by the embodiment of the invention, as the plurality of channels supporting different protocols are arranged, the cache database can be connected and communicated with the client based on different protocols, and the compatibility of the power grid monitoring system based on the synchronous cache is further improved.
In some embodiments, referring to fig. 2, in combination with the content of the foregoing embodiments, the manner of obtaining corresponding function information according to a target service instruction is not specifically limited in the embodiments of the present invention, including but not limited to:
201. searching corresponding cache information in a cache database according to the target service instruction;
204. and decrypting the searched cache information to obtain the functional information corresponding to the target service instruction.
In the step 204, it should be noted that the cache information is in an encrypted form, and what the client needs is the original data of the cache information. Therefore, the cache information needs to be decrypted to be restored to the function information required by the client.
According to the method provided by the embodiment of the invention, as the decryption of the cache information is realized, the functional information required by the client is obtained, and the confidentiality and the safety of the information in the synchronous cache process are further ensured.
With reference to the content of the foregoing embodiments, in some embodiments, a preset value and a preset condition are set in the target service instruction, referring to fig. 3, after searching for corresponding cache information in the cache database according to the target service instruction, the method provided in the embodiments of the present invention further includes:
201. searching corresponding cache information in a cache database according to the target service instruction;
202. comparing the searched cache information with a preset value;
203. if the comparison result triggers a preset condition, an early warning signal is sent to a client specified by the target service instruction;
204. and decrypting the searched cache information to obtain the functional information corresponding to the target service instruction.
In step 201-. For example, the client is a power distribution network abnormity warning unit, and the function information containing power distribution network key monitoring is sequentially encrypted and cached to obtain cache information of power distribution network key monitoring and stored in the relational database. And if the comparison result of the cache information in the relational database and the preset value triggers a preset condition, sending an early warning signal to the power distribution network abnormity warning unit.
According to the method provided by the embodiment of the invention, whether the cache information accords with the preset value or not is monitored, and if the cache information does not accord with the preset value, the early warning signal is sent to the client side to play a warning role, so that the abnormity of the power distribution network can be rapidly found and the notification and the subsequent processing can be carried out.
In combination with the content of the foregoing embodiments, in some embodiments, the method provided by the embodiments of the present invention further includes:
and selecting a preset channel matched with the network transmission protocol followed by the interface of the client, and storing the cache information required by the client into a cache database matched with the data type required by the client through the preset channel matched with the network transmission protocol followed by the interface of the client.
It will be appreciated that the external device or system needs to establish a connection with the client through its interface. Because the network transmission protocols followed by the interfaces of different clients are different, the cache information required by the client needs to be transmitted through a preset channel matched with the network transmission protocol followed by the interface of the client. The data type required by the client corresponds to a cache database matched with the data type, and the cache database is used for storing cache information required by the client.
According to the method provided by the embodiment of the invention, the transmission process of the cache information based on different client network transmission protocols is realized, so that the accuracy of the client for acquiring the required information is ensured, and the accuracy of the synchronous cache-based power grid monitoring system in the information transmission process is improved.
