First, the hot weather led to the rapid growth of power generation
Recently, by a wide range of high temperature weather, some areas of the power load continues to climb. As of July 5, in addition to the Northeast Power Grid, the other five regional power grids, the maximum load of electricity have hit a record high. Among them: North China Grid 14015 million kilowatts, East China Grid 150.76 million kilowatts, Central China Grid 96.15 million kilowatts, Northwest China Grid 32.93 million kilowatts, South China Grid 96.35 million kilowatts. Shandong, Tianjin, Jiangsu, Zhejiang, Anhui, Fujian, Hubei, Henan, Shaanxi, Ningxia, Xinjiang, Guangdong, Hainan, 13 provincial power grids, the largest power load record has also been successively refreshed.
In terms of power generation, since late June, the country's daily power generation rose rapidly, consecutively breaking through the peak of daily power generation of 12.203 billion kilowatt-hours on July 21 last year. In July, the growth momentum is more rapid, daily power generation has been maintained at more than 12.5 billion kilowatt-hours, July 5 reached 12.934 billion kilowatt-hours, a new record high.
Second, the hydroelectric power increase strongly support the power supply
Since May, with the rainfall increased significantly, the major river basin water situation rapidly improved, the drought in the southwest region to ease, the key hydroelectric power plant adjustable water increased significantly, the hydroelectric power out of the power to continue to increase. According to the state grid company statistics, in June, the national hydropower generation 71.5 billion kilowatt hours, an increase of 29.4%, higher than the thermal power growth rate of 16.7 percentage points; hydropower on the national power generation growth contribution rate of 33.9%. Compared with the same period last year, the increase in the amount of hydropower corresponding to the reduction of about 7.5 million tons of coal demand, a strong relief of coal supply and thermal power unit operation pressure.
At present, the national key power plant coal stock is basically normal, the central China Power Grid, East China Power Grid, South China Power Grid coal stock has increased. As of July 4, the State Grid monitoring 429 key power plant coal storage 58.07 million tons, for 18 days of use, than the end of May up 2 days. Among them, 32 days of coal available in central China Power Grid, up 11 days from the end of May; 18 days of coal available in east China Power Grid, up 3 days from the end of May; 20 days of coal available in south China Power Grid, up 4 days from the end of May. Qinhuangdao port stock 5.94 million tons of coal, belonging to the normal level.
Third, actively respond to high temperatures to ensure the safe and stable operation of power
In accordance with the requirements of the June 10th National Electricity Summer Television and Telephone Conference, the State Grid Corporation and the South China Grid Corporation to increase the optimal allocation of resources, and strive to consume hydropower resources, to reduce the abandonment of water and to actively organize and carry out emergency drills; power generation enterprises to strengthen the operation and maintenance of the unit, and strive to improve the coal inventory; Power operation authorities around the world strengthened demand-side management, improved the program of orderly power consumption, and made efforts to promote energy conservation and emission reduction. For example, about 1,160 enterprises in Zhejiang Province, which consume more energy, such as cement, iron and steel, chemical industry, papermaking, textile printing and dyeing, have respectively implemented phased centralized overhaul and shutdown to allow for electricity and staggered peak electricity consumption during high (sharp) peak hours. As a result of the more adequate preparation, the current national power operation is basically stable.
During the summer peak period, the national power load will remain high. According to the Central Weather Bureau forecast, the next week in North China, Central China, East China and other places will continue to be hot and rainy weather. Affected by this, the power load will continue to climb. All relevant departments and enterprises will continue to strengthen monitoring, coordination, timely handling of various emergencies, to ensure that residential life and other key areas of electricity demand.

Informatization construction
Plant-level monitoring information system (SIS), asset management system (EAM), office automation system (OA), human resources system (HR), financial system ......With so many informatization systems, Huaneng Dalian Power Plant the How to better integrate and optimize these systems based on different platforms and prepare for future system construction .
Integration Challenges
Huaneng Dalian Power Plant, located in Dalian Bay Town, Dalian City, is a wholly-owned company of Huaneng International Power Company Limited, with a planned installed capacity of 2.1 million kilowatts. At present, the power plant has four 350,000 kilowatts units with a total installed capacity of 1.4 million kilowatts, which is the benchmark power plant of Huaneng Group, and also a mega power generation enterprise in China.
Over the years, Huaneng Dalian Power Plant has been striving to build itself into a digital power generation enterprise and a modern thermal power plant with international competitiveness. In recent years, with the continuous promotion of the reform of the power system "separation of plant and network, bidding for Internet access", the informationization construction of Huaneng Dalian Power Plant has achieved remarkable results. At present, the plant has built a mature computer network environment and hardware architecture, as well as a basically perfect enterprise informationization application system. Among them, the information systems that have been implemented or are being implemented are the plant-level monitoring information system, asset management system, office automation system, human resources system, financial system and so on.
So it can be seen that the importance of information technology construction, so that Huaneng Dalian Power Plant has a good foundation of information technology, and in the production, finance, equipment, materials and other areas have accumulated rich experience and sufficient data. At the same time, the mature computer network environment and hardware architecture, but also to ensure that the power plant in the future can use advanced technology to further improve the depth and breadth of information technology applications.
However, like many companies that have been building information technology for a long time, Huaneng Dalian Power Plant has encountered a problem on the way to building information technology - how to integrate and optimize the many systems based on different platforms in order to give better play to their benefits?
To solve this problem, the implementation of EIP (Enterprise Information Portal) is undoubtedly a good choice.
EIP can integrate and optimize the existing internal and external systems of the enterprise, so that employees, customers, suppliers, partners can access, extract, analyze, and store the personalized information they need from a single platform. At the same time, they can also use this information to make reasonable business decisions and implement them. EIP can help enterprises optimize business operation processes and improve work efficiency by providing timely and accurate information.
With the continuous development of information technology, the new generation of enterprise information portals pay more attention to collaborative work, can help enterprises to realize business process automation, and at the same time, pay more attention to the extension of the enterprise external, such as support for XML, Web Service, etc. The reasonable application of the EIP, not only for the enterprise staff to provide a window of the application, but also the best way to convey the information of the enterprise to the outside world.
According to the EIP, it is the best way to communicate the information to the outside world.
It is understood that Huaneng Dalian Power Plant has long been aware of the importance of EIP for the construction of enterprise information technology, and has implemented and applied the EIP system. However, with the rapid development of the company's business, the plant's management and business put forward higher requirements for the EIP system. The new requirements are mainly reflected in the requirements for the system's extensiveness, ease of use, security, scalability, advancement, easy maintenance and integration of information. The original EIP system can not well meet these needs.
Portal Platform
By re-examining the original information system, optimizing and reorganizing the existing management business processes, and exploring the deeper needs of management, Huaneng Dalian Power Plant decided to carry out a technological transformation of the intranet platform: integrating the application systems on the basis of the original information technology, and reconstructing the power plant's enterprise information portal with knowledge management as the core.
The new enterprise information portal should not only retain the advantages of the original EIP system, but also have greater improvements in terms of extensiveness, ease of use, security, scalability, sophistication, maintainability, and integration of information, so as to help Huaneng Dalian Power Plant to comprehensively improve its management through informatization.
In order to ensure the smooth implementation and successful application of the EIP project, Huaneng Dalian Power Plant has identified four major principles for the construction of the project.
First, leading technology. Mature and leading technologies should be adopted for the construction.
Second, tailor-made. Do not blindly pursue the new, full, high, but according to the current state of information technology in the power plant, from the point of view of whether there is enough data accumulation, whether there is a reasonable business process as a support, whether it can be accepted by the user, to develop a reasonable implementation plan and implementation plan.
Third, step-by-step implementation. Adopting the strategy of "overall planning, step-by-step implementation" for EIP construction. Huaneng Dalian Power Plant plans to lay a good foundation to improve the EIP infrastructure, and then implement it step by step according to business priorities, and formulate a step-by-step implementation strategy to lead the way.
Fourth, flexibility. Considering the external business environment and internal business process changes, the EIP system should have enough scalability to ensure that the system can adapt to the continuous development of the enterprise.
After careful comparison and investigation, Huaneng Dalian Power Plant finally chose the BEA ALUI-based enterprise information portal solution provided by BEA.
It is understood that the reason why Huaneng Dalian Power Plant chose BEA ALUI, the most critical reason is that ALUI is currently on the market based on the advanced SOA architecture to build the product, can provide a number of functional frameworks, including collaboration, publishing, content management, search, workflow and analytics, as well as a large number of functional modules corresponding to it. These can be easily used by Huaneng Dalian Power Plant for configuration and customized development.
In addition, ALUI can be deployed in a flexible and extensible way for power plants in the form of components. This is critical for Huaneng Dalian Power Plant, which is in the midst of rapid changes in the power industry. all of ALUI's functional frameworks and modules are tightly aligned with its infrastructure, complementing each other and unifying the whole, and can be configured to quickly meet the needs of Dalian Huaneng through simple configurations. This configuration concept is not only reflected in the high efficiency of development and low cost of maintenance, but also in the flexibility of expansion.
It is worth noting that Java and . Enterprises must consider the effective integration of Java and . Not only Huaneng Dalian Power Plant, many large enterprises want to have a tool that can integrate all applications across Java and . The most prominent feature of ALUI is its cross-Java and . This can effectively help Huaneng Dalian Power Plant to quickly integrate the application systems currently used and provide support for future applications.
Two main lines of MIS
Under the guidance of the four principles, and through the ****same efforts and cooperation of many parties, the Huaneng Dalian Power Enterprise Information Portal project passed the acceptance and was successfully launched.
The project integrates enterprise website and enterprise portal, which not only integrates the existing EAM, OA, SIS and other application systems of the power plant, but also integrates part of the daily management of the power plant into the portal, which further standardizes the management of the enterprise, enhances the level of management, improves the efficiency of collaborative office work, and accelerates the speed of development and construction, and reduces the wastage of all kinds of resources caused by separate development and re-integration.
HuaNeng has been able to integrate the portal into the enterprise management.
Huaneng Dalian Power Plant related project leader Deng Yu said that the successful implementation of EIP for the power plant to build a new information management system with its own corporate characteristics, that is, in addition to the MIS project in addition to the EAM, the vast majority of the document management, workflow management, and other **** of the module is organically integrated into the portal to achieve, rather than simply applying the integration. As a collaborative work platform for daily management within the enterprise, the successful application of EIP has helped Huaneng Dalian Power Plant to finally form the two basic threads of MIS - EAM and enterprise portal.
More importantly, BEA SOA concepts and methodologies have met the portal application needs of Huaneng Dalian Power Plant. In particular, the cross-Java and .Net integration realized by EIP has laid a solid foundation for Huaneng Dalian Power Plant's future informationization construction
