China's investment in distribution networks is less than half that of the transmission grid. In its 2013 mid-year work conference, the State Grid mentioned that "the development of distribution network construction is a pressing matter of the moment." The first time the distribution network construction was raised to the highest priority level. The provincial companies in the provinces are formulating the investment plan for 2014 in accordance with the requirements of the State Grid. The focus is on distribution network construction.

Distribution automation is an indispensable part of distribution network construction. According to statistics, in 2012, China's distribution automation coverage rate was less than 15%, while the level of distribution automation in developed countries reached more than 50%. With the new type of power supply and load directly connected to the distribution network, new technical problems and challenges are brought to the safe and stable operation of the distribution network; on the other hand, from the perspective of power supply reliability, the distribution network system in China has a long history. The way to go. The solution to these problems depends on a high level of distribution automation systems. Strengthening the construction of distribution automation is the inherent demand for power grid development.

It is estimated that in the next five years, in the most pessimistic case, the practical distribution automation system will be promoted nationwide with an overall market size of approximately 71.16 billion yuan. The standard model is a neutral assumption, and the investment scale will be 118.6 billion yuan; optimistic scenario To promote integration, the overall investment scale is 177.9 billion yuan. Under the assumption of a neutral investment scale, the average annual investment is 23.72 billion yuan, and the total investment in distribution automation in 2012 is 5.5 billion yuan, and investment growth in the next three years is expected to maintain more than 50%.

Since the intelligent transformation of power distribution has relatively high requirements for the system integration capabilities of the corresponding enterprises, large-scale engineering project experience, and hardware and software integration capabilities, only large-scale enterprises that have both primary and secondary equipment and systems for the distribution network can benefit from it. Other companies, such as enterprises that only produce distribution network primary equipment, distribution network secondary equipment and systems, or enterprises that only involve primary distribution network primary equipment, are unlikely to benefit from the large investment in distribution intelligence due to their own level and capabilities. .

The company that benefited from distribution automation was mainly Xuji Electric and Guodian Nairui. As for Jicheng Electronics and Sifang, due to its strong competitiveness in the field of distribution network automation, after the short-circuit of the primary equipment, It is hoped that in the future, the distribution network will benefit from the climax of the distribution network; each distribution network company will actively develop new products to meet the construction network distribution climax, and it is also good for the Academy of Electric Power to acquire new products that have “give birth certificates”.
