A new real-time data acquisition platform for power industry based on PI system in large data era

The era of large data is gradually coming, unfortunately many enterprises are not ready, many areas are still urgent to awaken. "Data mass, lack of information" is a considerable number of enterprises in the data after a large concentration of embarrassing problems.


in the electric power industry, with the continuous deepening and advancing of the intelligent power grid construction, the mass information generated by the power grid operation grows exponentially. Gathering point more and more, conventional dispatching automation system hundreds of thousands of points, and the distribution of electricity, data center will reach millions or even tens.


Power Large data analysis imminent


Current, power grid business data is broadly divided into three categories: first, the Power enterprise production data, such as electricity generation, voltage stability and other aspects of data; second, power enterprise operating data, such as transaction price, sales, electricity customers and other aspects of the data; third, power management data, such as ERP, integration platform, Collaborative Office data. The "Quantity class time" characteristic of large data has been further highlighted in the massive and real-time power grid business data, and the power large data analysis is imminent.

If the
can make full use of the actual data based on the grid, in-depth analysis of it can provide a large number of high value-added services. These value-added services will be beneficial to power grid security detection and control (including catastrophe early warning and processing, power supply and power dispatching decision support and more accurate power consumption forecast), customer power consumption behavior analysis and customer segmentation, power enterprise meticulous operation management, etc., to achieve more scientific demand side management. These real-time data and the historical data of precipitation are the foundation of the power grid enterprise to realize lean management.


the defects of existing real-time database


at present, most of these data are stored in relational database, and with the increasing of intellectualization, the power industry has put forward more and more demands on database processing ability, storage space and query ability.


Real-time database is a database management system specially designed to deal with massive real-time data, which has very high storage speed, query retrieval efficiency and data compression ratio for massive and real-time high frequency data collection. Typically, its processing capacity can be up to hundreds of thousands of events per second, with a compression ratio up to 30:1.


Although compared to relational databases, the advantages of real-time database are obvious, but there are many problems in the existing database products: not support cross-platform application, difficult to meet information security requirements, data compression algorithm single, processing capacity is limited, do not support quality code storage, not support multithreading two times development and expensive, Weak technical service capacity, etc.

Advantage
of
PI real-time data acquisition platform

Proud when the Software Pi system real time data acquisition platform after 30 years of development, widely absorbing the practical experience of various industries, and gradually make up for the above defects. Proud when the software Greater China General Manager Mr. Shi Zhiyong in an interview with reporters, compared to the traditional real-time data acquisition platform, PI system advantage is obvious. The main performance in the following aspects:


supports the visual presentation of facility data and operational variables to understand and track the lab environment;


increased credibility while reducing the time required to implement energy optimization projects;


provides a non-invasive environment that can safely extract data from production systems to perform independent analysis, reporting, and visualization operations;


provides a collaborative environment that allows access to previously unavailable orphaned data;


long-term data storage and maintain its original accuracy, so that the annual "high-definition" comparison and analysis.


PI system widely used in power industry is the leading

The
PI system stores all production data in the factory for a long time in the form of data, and satisfies the requirement of data collection, storage and display quickly and efficiently. Because of its excellent function and reliable performance, it has been widely used in the construction of power plant information at home and abroad, which occupies a leading position in the application of real time/historical database products in power industry. According to Shi Zhiyong, the current PI system has been in the national network, the South network has been applied, and a few days ago, proud of the software and Cisco co-sponsored the South Network a forward-looking study, and Huaneng International, Guohua, etc. also have cooperation.


PI System provides visual display of the Enterprise Production Process Virtual window. Based on reliable production information, managers can monitor the operation of the entire enterprise. PI real-time obtains the original production data of each actual data source, the user through a group of user configurable report, from distributed in the whole enterprise's desktop computer, can see the current and historical production running condition. These valuable information can also be stored online for several years for future use, allowing users to keep abreast of the operation of each unit, each device, and the enterprise at different levels.


The PI system has powerful real-time data acquisition function, can collect the raw data from different data sources in real time, and through the system provides the user can configure the report, the Analysis tool and the Web software tool and so on, in the enterprise or the Management department's desktop computer, the portable computer or the mobile PDA, Real-time display of current and historical health. For operational management of valuable data information, the PI system provides online storage for up to dozens of years, and provides real-time data and information support at all levels (7 days per week, 24 hours per day) for operational unit level, complete facility level, entire enterprise, or management organization level.

As a core part of the real Time information architecture of Enterprise and Management organization,
helps to transform real-time data into key information of operational management decision making, which is the important information of integration in business system. At present, a number of management agencies, organizations or enterprises, including the world's top 500 to medium-sized enterprises, the real-time information management model applied to production capacity, product quality and reliability, and achieved a sustained and significant success
