The technical support of the Internet of Things, the growth of video surveillance, and the rapid development of the smart grid, icing on the cake for smart city construction and smart life.
IoT technology becomes an important support
Currently, the development and application of the Internet of Things is in its infancy, and countries and regions such as the United States, Europe, Japan, and South Korea started earlier. The application of the Internet of Things in China is still in the early stages of development. Many fields have launched a series of Internet of Things pilot and demonstration projects, and have made initial progress in the fields of power grids and industrial automatic control.
The smart grid will realize the integration of information flow, power flow, and business flow. The flow of information must rely on thorough information perception, reliable data transmission, a sound network architecture, and intelligent management of massive information. The comprehensive perception and collaborative processing capabilities of the Internet of Things can comprehensively improve the depth and breadth of information perception in all links of the smart grid, and help improve the power system analysis, early warning and disaster prevention capabilities.
The State Grid Corporation ’s Internet of Things demonstration application construction has been piloted by State Grid Liaoning Electric Power Co., Ltd. and State Grid Ningxia Electric Power Company since last year, covering power transformation, power distribution, and computer room management. The company's information and communication work department takes the construction of the smart grid as an opportunity to apply the Internet of Things technology to the grid, which will generate huge social and economic value.
Video surveillance system helps the Internet of Things grow rapidly
With the continuous development of China's power industry, higher requirements have been placed on the operation of various major equipment and personnel operations in power transmission and transformation enterprises. Power transmission and transformation enterprises have adopted modern management methods and methods from remote control and remote communication. , Remote measurement, remote adjustment to remote viewing, continuously improve the level of production automation. Through the substation security and video monitoring system, you can remotely inspect the operation of various equipment and the operation of personnel, obtain real-time alarm information on the spot, and recall the accident through video recording.
In recent years, the development of smart grids has gradually become a mainstream trend in the development of China's power system industry, and smart substations are an important part of smart grids. Intelligent substation is the use of advanced, reliable, integrated, low-carbon, environmentally-friendly smart equipment. With the basic requirements of digitalization of the entire station, communication platform networking, and information sharing standardization, it automatically completes information collection, measurement, control, protection, measurement and Basic functions such as monitoring, and substations that can support advanced functions such as real-time automatic control of the power grid, intelligent adjustment, online analysis and decision-making, and collaborative interaction as needed. Networking, digitization and automation of intelligent substation management are inevitable trends in power development requirements. Unattended, comprehensive management and safety management of substations are the only way for power grid modernization.
Security video surveillance technology has been applied for a long time in the power industry. The main reason is that the geographical location of substations in the transmission grid is relatively scattered. There are many hundreds or even thousands of square kilometers in dotted areas. There is an urgent need for online video surveillance. The use of electric power 2M dedicated communication lines can be more convenient for video monitoring networking. The early substation network video monitoring system can also be called: substation remote image monitoring system (remote viewing system). After several years of development, the substation remote viewing system is not limited to network video surveillance applications. It integrates applications such as perimeter defense, environmental monitoring, lighting control, access control, and fire control linkage of substations. Substation auxiliary systems are constantly evolving and developing.
The research and application of smart grid security and video surveillance systems are in a rapid growth period in China. It is applied to the field of smart grid digital substations. The high-definition video images are used to analyze and record the operation status of key power grid equipment to achieve online remote monitoring Guardianship is of great significance in promoting the safe production of electricity.
Smart grid becomes an important promoter of smart cities
Smart grid is the city's construction of clean energy access, energy saving and emission reduction, information infrastructure and other facilities. It is also one of the foundations for the development of urban related industries. Liu Jianming pointed out at the meeting that the main contribution of smart grids to smart cities is mainly reflected in four aspects.
First, the economy. Smart grids accelerate the energy-saving transformation of existing industries, create new industries, and promote the transformation of economic structures. Second, energy. In the development of smart grids, by promoting technologies such as “substituting electricity for coal and electricity for oilâ€, the proportion of electrical energy in final energy consumption will be increased.
Third, information. The construction of smart grid can not only improve the level of urban informatization, but also promote the "three network integration" and create an urban public network platform. Fourth, environmental protection. The establishment of a smart grid is conducive to protecting the environment, improving energy efficiency, reducing energy consumption and reducing carbon emissions.
Smart grid is an important basis for the subjective development of urban intelligence and an energy carrier for objective needs. Smart grids can not only ensure the safety and reliability of urban electricity use, promote urban green development, build urban nervous systems, and improve the development of urban related industries, but also play an important role in supporting the development of smart cities in the construction of urban service platforms.
Smart grid promotes smart home applications
Smart grid is undoubtedly one of the mainstream directions for the development of the overall power system in the future. At the same time, its construction and promotion will promote the development of smart home technology and contribute to the popularization of smart home applications.
Smart grid cities have appeared in the United States in 2008, and the first large-scale smart grid was built in Florida in 2013; the German "E-Energy" plan has a total investment of 140 million euros, from 2009 to 2012 in 6 Empirical experiments of smart grids will be conducted at locations; Japan plans to fully popularize smart grids by 2030; China's State Grid Corporation plans to basically build a strong smart grid with information, automation, and interactive features in 2015. In the near future, this trend will completely change our living habits, and a smarter and more environmentally friendly smart life model is about to start.
The country is vigorously promoting the work of the smart grid. The front-end smart meters are installed quickly, but the back-end data integration is still far behind. In addition, with the development of smart grids, the demand for the degree of intelligence of power dispatching systems is increasing. Since the "Twelfth Five-Year Plan", the State Grid Corporation has proposed an integrated dispatching and operating system that requires information communication operation monitoring, fault handling, and dispatching and commanding to achieve "great integration", which puts more stringent requirements on power communications technology.
On February 14, 2012, China officially promulgated the "Twelfth Five-Year" Development Plan for the Internet of Things. The "Planning" delineated nine major applications for development, including industrial smart industries, smart agriculture, smart logistics, smart transportation, Smart environmental protection, as well as smart grid, smart security, smart medical care and smart home for people's livelihood.
Today's rapid development of smart grids has promoted the construction of smart communities / buildings around the world. The communities / buildings are the most basic unit of living in cities and the terminal of smart electricity consumption. In addition to satisfying basic life functions, smart communities also need to consider the five elements of safety, health, energy saving, convenience, and comfort. With the popularization of smart meters and electricity collection systems, electricity-related life experiences in residents ’homes will become more convenient .
According to the survey and analysis of key enterprises, Chinese enterprises generally have the problems of low informatization, inadequate information institutions, inadequate investment in informatization construction and high construction costs, and insufficient cooperation in operation and management. On the whole, there are regional imbalances, and they are still mostly at the surface application level, and have not penetrated into all aspects of enterprise operation and management. Insufficient investment in enterprise informatization and lack of professional information technology talents are two major problems.
The main problems at this stage are:
Recognize the problem
Recognition is the first. Without awareness improvement, it is impossible to generate enthusiasm in action, and of course, it is impossible to achieve better results. Many people do not realize that information systems can manage enterprises in an orderly manner, and can be very helpful for leaders. Valuable auxiliary decision-making information, and it is better than people in speed and accuracy.
High-level understanding of enterprise informatization is not correct and sufficient
Some enterprises with better conditions are satisfied with the current situation, and believe that without improving the construction of informatization, enterprises can still do well. Therefore, they do not pay enough attention to the informatization construction of enterprises. In the early days of enterprise informatization, senior leaders of some enterprises have high expectations for information technology, hoping to obtain higher benefits through enterprise informatization. As a result, once they see an increase in investment costs and no significant improvement in efficiency, they lose confidence. Senior leaders cannot look at the problem from a long-term perspective, rushing for quick gains and shortcomings, which is not conducive to the continued development of informatization.
Some managers have rich experience in long-term management practice. They often value their subjective knowledge, hold on to their deficiencies, and are unwilling to actively analyze and absorb new management methods and advanced management methods. Informatization poses a huge threat to their status; Active advocates continue to use outdated management ideas or outdated management methods due to traditional customary thinking. What they need to learn is not simple operation methods, but management concepts for obtaining analysis and decision-making information; professional and technical personnel are due to the continuous growth of modern technology The complexity has become more and more narrow. In the face of the lack of coordination and interconnection on the whole, the system is in a fragmented situation on the macro level, which affects the reality of overall benefits. Technicians are unable to extricate themselves in various constraints and limitations.
