Power communication has applications in many aspects of smart grid systems, such as the safe operation of power grids and power distribution processes, making it possible to develop intelligent and intelligent information. At the same time, it should be noted that the application of power communication in the smart grid also has certain deficiencies. It is necessary to actively strengthen the research on power communication technology and cultivate the power communication talents, so that the smart grid can achieve sustainable development.
The status quo of China's power communication
China's power companies have made great progress in the development of these years. China's power grid is in the forefront of the world, and the construction of smart grids has begun to take shape. Of course, the development of smart grids cannot be separated from the development of power communications. The development of power communication not only speeds up the construction of smart grids, but also expands the power communication business. Based on the important position of power communication in the smart grid, China's power sector has also stepped up research in the power communication industry, making the research and implementation of power communication develop simultaneously. In addition, the management of power communication has been compared with the past. With even greater changes, management has become more detailed. Academic research in power communication has also been developed sustainably, so that advanced communication technologies will continue to be used in power communications. The achievements of China's power communication mainly include the realization of nationwide network construction, which provides a good foundation for the construction of smart grid, and the power communication technology has also been greatly improved. This will make the quality of communication more stable. Finally, the number of communication agencies has increased significantly, and the quality has also been greatly improved.
Several requirements for smart grid to power communication
In recent years, with the rapid development of the economy, the construction investment of the entire smart grid is also increasing. The huge grid system leads to the difficulty and complexity of grid dispatching, which puts higher requirements on the power system. The power system should be able to monitor the operation of the entire power grid and make timely and effective analysis of some parameters in the power grid. In order to make the smart grid more perfect and mature, the power communication system needs to have the following functions.
1. Instant messaging system
The instant messaging system, SIS, its main purpose is to be able to analyze and process some information and data of the grid operation in the first time. It is based on the rapidly developing Internet technology, and then the national power data network. reference. The instant messaging system can upload power information in time, and has high technical protection capability, which can effectively ensure the security of information.
2, EMS system
The main function of the ESM system is to organize and classify the information data of the power grid. In the working process of the system, it first obtains the latest information data from the grid, and then classifies the data according to the degree of urgency and then transmits it to the instant messaging system. In order to ensure the accuracy and efficiency of information transmission, different information is transmitted from different transmission interfaces and channels, and the transmission speed will be different.
3. Energy metering system
The smart grid requires that the energy metering system not only perform general measurement work, but also requires the system to perform segmented storage of data and bidirectional measurement during measurement. These requirements are important for the settlement of electricity costs and the effective control of electrical energy. In addition, the smart grid's metering system also needs to complete a series of tasks such as automatic information collection, data pre-processing, remote communication, and statistical analysis. This is also the basis for the effective integration of smart grids with new energy grids in the future.
4, demand side management
At present, in the communication with electric energy customers, the smart grid is mainly carried out through the wireless public network, which leads to the number of grid end users is also very large, but the business density is not high. If Unicom CDMA or mobile GPRS technology is adopted, the power unit can be used to detect the user's power usage in a timely and effective manner.
