Abstract: with the rapid development of China's power industry, smart grid has become an important part of the development of the power industry. Firstly, the smart grid is described; secondly, the characteristics of smart grid technology are analyzed; finally, the application of smart grid in power technology and power system planning is summarized, hoping that the content of this paper can help the relevant staff.

1. smart grid

With the rapid development of society and economy, smart grid is well known by people, and with the continuous maturity of its technology, its application has become more and more extensive. Through its reasonable application, many men's problems that people are facing have been solved, with good application effect, which is also the case, smart grid is favored by people. During the practical application of smart grid, through the reasonable application of the network, the corresponding communication is completed, so as to realize the dynamic monitoring of the operation of the whole power system. Through the rational application of smart grid, we can ensure the stability and reliability of power system in operation, and then ensure that in the rapid development of society, we can meet the demand of the whole society for power. The development of smart grid needs the support of computer technology. With computing technology, smart grid will appear. From the current development of China's power industry, smart grid is the development direction of the whole industry, and it is also a reasonable way to quickly improve the power supply capacity of the power grid during the specific operation period, which is of great significance to ensure the reasonable operation of the power grid.

2. Technical characteristics of smart grid

2.1 self healing

The structure of the power system itself is relatively complex, and there will be power fluctuations and other problems during operation. The occurrence of this situation will have adverse effects on the power technology, as well as the operation of the grid, the rationality and stability of the grid system in the specific operation, which will reduce the transmission quality. In the specific operation of smart grid, it has the characteristics of self-healing. Therefore, during the specific operation, it can screen the original parts of the whole system that have problems, and can take reasonable measures to complete the corresponding isolation, so that the staff in the power company can get treatment, repair time and conditions, and provide strong support for ensuring the stability of power grid operation. The support of force. 2.2 in the specific operation process of strong power system, it will be interfered and influenced by various external factors such as equipment and environment, so it will lead to various faults and problems in the operation of power system, which will have corresponding impact on the quality and efficiency of transmission and distribution. In view of this phenomenon, during the specific operation of smart grid, reasonable measures will be taken to affect the smart power.

In order to ensure the safety of the power grid in the operation process and effectively avoid the occurrence of various safety problems, reasonable resistance should be made to the stable factors of the network operation.

2.3 integration

During the actual operation of smart grid, it can collect and analyze the data and information of various data contents involved in the grid, so that all information contents involved in the grid can be shared and integrated, which to a certain extent also promotes the development of the whole power system to the direction of scientific, standardized and standardized, which makes the benefits of grid operation get further. Step up.

2.4 optimization

During the specific operation period of power grid, smart grid technology can complete the corresponding analysis and division work according to the management work content. Through this processing method, the cost of power grid system in the specific operation period can be reduced, and the economic benefits of enterprises in the operation process can be further improved.

Application of smart grid in power technology and power system planning3.1 automatic inspection

During the specific application of smart grid, in the application of Internet technology of power grid, it can better complete the remote data transmission. At the same time, in the specific operation process, it can complete the all-round monitoring of the specific operation of power supply system through the application of corresponding monitoring equipment. In the actual operation, through the reasonable application of the host operation base, the staff can In the specific inspection period, according to the problems existing in the operation of the power system, reasonable troubleshooting should be carried out to check whether there is a potential safety hazard. Once there is a problem in the power system, the smart grid can make a timely response in the operation, and can report the information in time, so that the power supply company can grasp the problems in the operation of the smart grid in time, take corresponding measures to deal with the problem reasonably in time, and take reasonable measures to complete the treatment of the problem before the fault occurs. So as to avoid the occurrence of safety problems.

3. automatic execution 

Smart grid has strong self-healing in the specific operation period. When transmitting data, it needs to complete the corresponding analysis work according to the specific situation, at the same time, it needs to be able to quickly make the corresponding response, and for the corresponding problem processing, it can be completed through the intelligent system, so as to ensure the rationality of

smart grid in the specific operation process and meet people's demand for power. People provide higher quality services.

4. Conclusion:

Smart grid is an indispensable part of the development of modern power industry, which plays an irreplaceable role in solving various problems in system and power technology. In recent years, Chia's economy has entered a stage of rapid development. The power industry plays an increasingly prominent role in the development of natinal economy.
