Electricity has become an indispensable energy source in social development. Electric power plays an irreplaceable role in the national economy and has made great contributions to the economic development of our country. We have to pay attention to the important role of the power system. In recent years, with the development and progress of science and technology, the power grid is also developing rapidly. To a certain extent, the safe operation of power grids has led to the stability and progress of social development. The application of the key technologies of smart grid dispatching automation has also become a key core technology in the rational operation of power grid systems. The reasonable dispatching of power grids can maximize the power grid performance Meaning in real life. This article, from the smart grid dispatching automation key technology to illustrate the key technologies of smart grid dispatching automation. Into the 21st century, the world is in a period of rapid development, social development, science and technology are in progress, for a wide range of household appliances gradually more equipment, in addition to industrial electricity, the average household electricity in the country each year It is also showing an upward trend year by year. Reasonable dispatching of the power grid is particularly important. How to transport more electricity through certain grids and bring convenience to more people has become a question that every country is thinking about. Compared with other countries, our country has a vast territory and a large population. As a whole, our population is predominant, with a slight deficit in per capita resources. In order to be able to get the limited resources to be used reasonably and efficiently, we have to think more about the ways of utilizing resources. Intelligent scheduling in the power grid is an effective way to make rational use of resources. The following from the current situation of China's national grid to analyze the current situation of China's national grid dispatch. 1 grid scheduling problems In the whole operation of power, grid dispatching is the baton of power system operation. The direction of dispatching system is the direction that power needs to go. The power dispatching system is the key to the normal operation of the entire power system. Grid scheduling gradually intelligent, automated development, which is to ensure the rational operation of power is an important guarantee. There are also many practical problems in the process of power grid from artificial to intelligent and automatic transformation. Nowadays, the biggest problem in the dispatching of China's home power grid is that most of the dispatches are dispatched by manual operation and dispatched by electric power, which requires a large number of personnel to operate because it is a very large system and must be Many people's efforts to ensure the normal use of electricity in the country. If there is a problem in power operation, it needs a lot of personnel to overhaul. Our country has not yet fully achieved the ability of the system to automatically repair the fault. Now the system can not repair the fault of the circuit system itself. The failure of the power system is an unpredictable problem. After the problems are dealt with, the problems that can not be solved before the problems occur are somewhat forecasted, which to a certain extent weakened the efficient operation of the national power grid. How to predict the existence of the problem before it occurs, and to reduce or repair problems in the system in advance is a prerequisite for the emergence of grid dispatching intelligence in the national grid. 2 National Grid integrated system design The key technologies of smart grid dispatching automation have been used in the power grids of some provinces, which to some extent make a certain contribution to the optimization of the national grid system. Integrated system design, you can put each branch of the computer data and the host computer connected to each other, to a certain extent, to achieve the sharing of data and information to achieve common management purposes. This method can monitor and manage the power grid to a certain extent, and notify the duty personnel in advance before the problem occurs. The duty personnel repair the circuit fault that will appear on the premise of knowing the fault to occur. To reduce the huge losses caused by the failure, can play a role to avoid or reduce losses. 3 monitor the entire system network environment A good system of normal operation, requires a safe and stable environment. The same power system also requires a normal operation of a safe, stable and good environment, in order to play a greater advantage. A virtuous cycle of the power system requires a good environment. This good environment includes a good system of computer platform, a benign network environment, the environment is safe and virus free. In the system to be isolated virus security measures, install anti-virus software, real-time update the database, the virus program isolation, at any time to fill the system loopholes. The only way to ensure the healthy operation of a system in order to ensure the safe operation of the entire power system. There are some advantages in the key technologies of smart grid dispatching automation when there are deficiencies. The key technologies of smart grid dispatching automation have some differences with the traditional grid application technologies. Smart grid dispatching automation can to a certain extent, the entire power network operation from the overall to the monitoring and supervision. That is the so-called monitoring of power system panorama information. The so-called grid panorama information refers to the accurate time section "is more correct" complete "standardized business information and power information. Intelligent system also with high efficiency, all-round, modular to achieve the power grid to achieve global management. At the same time for the purpose of full production for economic development provide a full range of dynamic support. Intelligent also through the network connection to increase the real-time monitoring of the entire network system, can predict the duty in advance, the emergence of the fault or give a warning, can make up for the unmanned state of unknown problems, to some extent Played a predictable role. The intelligent system will also form a module-based power grid management mode, through a small module to achieve network management for the global power grid, when a small module problems, cut off the system power or isolation, making A small system in the event of failure, will not result in a real system greater losses. This is a typical difference between intelligent systems and traditional systems. Intelligent system to achieve the perfect combination of man and machine for the power grid to conduct a full range of monitoring.
HCFCs
(hydrochlorofluorocarbons) are the second generation of fluorine based gases,
the original replacements for CFCs.
These products, which include R22, R123, R401A, R401B, R402A, R402B, R408A,
and R409A, are
categorized as having medium ODP (Ozone Depletion Potential) and
medium to high GWP (Global Warming Potential). Consequently, they offer a
slightly more environmentally friendly alternative to CFCs. They also often
provide a quick and simple "retrofit"
of existing CFC equipment.
As
HCFCs contribute both to ozone depletion and global warming, the use of HCFCs
is being phased out as
part of global legislation, such as the Montreal
Protocol. Some countries and regions are operating
an accelerated phase out.
Zhejiang
Zhonglan Refrigerants Co.,Ltd sell a wide range of HCFC products
like R22, R141b,R142b in many locations and in a variety of packages including
cylinders, drum tanks and iso-tank supplies. This includes reclaimed HCFCs
in some locations. We also support the transition away from the use
of ozone depleting products and can offer advice on alternative products,
such as hydrofluorocarbons (HFCs) and natural refrigerants, which
have a lower impact on the environment.
Our factories passed ISO9001:2008,
ISO14001:2004 and TS16949:2009. With scientific enterprise development,
advanced production technology, solid technical assistance, overall quality
