Smart Substation Communication Solutions
With the continuous improvement of information technology, various production terminals and sensing equipment in the power plant have been upgraded to varying degrees, and the level of intelligence and automation of the power plant has been continuously improved. In this process, the communication transmission network, especially the wireless network, is the most convenient way for data uploading and distributing, which has contributed a huge force to the informatization construction of the power plant.
In this power Internet of Things construction, advanced sensing technology is used to comprehensively collect the state parameters of substation equipment, safety and fire protection, environment, power, etc.; the company's communication data network, artificial intelligence, mobile Internet and other modern information technologies are fully applied to fully perceive the construction status. , A smart substation for information interconnection and sharing. Realize intelligent applications such as "one-key operation sequence control, automatic inspection of equipment, intelligent linkage of main and auxiliary equipment" in substations, further promote intelligent and modernized operation and maintenance management of substations, improve the safety level of substations, improve the quality of operation and inspection of substations, and greatly increase operation and maintenance. benefit.
Therefore, there are key transmission schemes such as wireless network coverage and LORA in the domain. Finally, WIFI in the production area is fully covered, providing a basic wireless network environment for smart power plants, enabling personnel and smart devices to upload and download information anytime and anywhere within the entire plant, speeding up data flow and improving office efficiency; Wireless coverage roaming The technology enables staff to use their own mobile APP to access network resources at any place and at any time, which greatly saves work time and improves staff work efficiency; realizes WIFI coverage, combined with the whole plant monitoring system, for the subsequent realization of staff positioning and visual operation Provide a basis for information.
Environmental monitoring and fire safety data collection can be realized by LORA and other methods.
