State Grid Information and Communication Corporation creates an upgraded version of UHV "neural network"

UHV has the comprehensive advantages of long distance, large capacity, low loss and small land occupation, and is the highlight of "new infrastructure". The State Grid Corporation of China Information and Communication Corporation focuses on the construction of UHV supporting communication network, comprehensively accelerates the promotion and application of modern information and communication technology, and promotes the intelligent upgrading of the power industry.

At present, the construction of China's UHV supporting communication network is entering a peak period. In 2020, 10 new projects and 8 continued projects are planned, with a total investment of more than 1 billion yuan, both the number and scale of which are historical highs. The UHV supporting communication network is built simultaneously with the UHV power grid. It mainly carries the collection, transmission and processing of power grid production control signals and business management information. It is a "neural network" for realizing power grid automation control, commercial operation and modern management, and provides important guarantees for the safe operation of the UHV power grid. While doing a good job in the construction and management of the communication network, State Grid Information and Communication Company actively embraces new technologies, builds cross-regional and cross-provincial ultra-long-distance composite overhead ground wire OPGW optical fiber network, demonstrates the application of "large effective area" new optical fiber in UHV projects such as "Shaanxi-Wuhan", and carries out research and application of N×100G large-capacity communication transmission technology, which greatly improves the power communication transmission capacity and creates a long-distance, large-capacity, and highly reliable "upgraded power communication highway", which provides strong and powerful communication guarantee for the safe operation of the UHV power grid.

It is understood that the construction of UHV supporting communication network projects not only has a long industrial chain, but also has strong driving force. In recent years, based on the characteristics of UHV transmission business, State Grid Information and Communication Company has piloted the research and application of domestic 2M wavelength division multiplexing communication equipment and technology, and has improved the localization level of power communication network construction from the aspects of raw material selection, component development, special communication optical cable manufacturing, etc., and also boosted the industry confidence in the communication field.

Informatization is showing its strengths not only in the construction and development of new industries such as UHV power grids, but also in the upgrading of power infrastructure. State Grid Information and Communication Co., Ltd. has accelerated the construction of the IoT management platform around the core business scenarios of power transmission, transformation, and distribution in the operation of the power grid, and built a basic platform for the intelligent inspection of overhead transmission lines, signal collection and status perception of power "pan-terminals".

For example, in the past, whether the cable manhole cover was damaged could only be checked on site by personnel, which was time-consuming and laborious. Now, the manhole cover is equipped with a sensor device and then uploads the signal. The IoT management platform conducts real-time analysis, which can not only take intervention measures before the fault occurs, but also quickly locate and handle the fault after it occurs.

5G construction is rapidly developing in China. State Grid Information and Communication Corporation has also seized the opportunity to promote 5G to promote the intelligent upgrade of the power industry. According to reports, the application prospects of 5G in power grid operations are very broad. State Grid Information and Communication Corporation is combining typical application scenarios in the power grid to vigorously promote 5G network adaptability solutions for power grid business, 5G and power communication private network security hybrid networking technology research, etc., to empower the energy Internet with 5G technology in advance.
