Application of power automation in mining industry
The power system can be divided into five links: power generation, transmission, transformation, power distribution and power consumption. Power automation uses modern computer technology, communication technology, information processing technology, automatic control technology, etc. to monitor and control these five links. The industry of protection, protection and operation management is an indispensable part of the modern power industry and the "brain and nerve" of the power system.
Panorama of Power Automation Industry Chain
my country's power automation industry has formed a relatively mature industry chain. The upstream of the industry chain is the supply of raw materials and components for the manufacture of power automation equipment, involving the steel industry, software manufacturing, mechanical processing manufacturing, and electronic component manufacturing; the midstream is power automation equipment. Manufacturing can be divided into power grid automation equipment manufacturing and power plant automation equipment manufacturing according to different application fields; the downstream is the application field of power automation, which is also divided into power grid automation and power plant automation. The downstream of power plant automation is mainly generator sets. Power grid automation has a wide range of applications, including mining, petrochemical, and water conservancy and hydropower fields.
From the perspective of enterprises, the upstream of power automation involves a wide range of companies, with a large number of companies. Except for some products that are monopolized to a certain extent due to technical reasons, the remaining raw materials and components are basically in a state of complete competition. Good materials and components are supplied as electricity. The development of automated manufacturing has laid a solid foundation; midstream power automation manufacturing companies can be divided into power plant automation equipment manufacturing companies and grid automation equipment manufacturing companies. Benefiting from national policy support, the market demand for grid automation equipment is relatively large, and most companies are also concentrated In this regard; the downstream is the application field, mainly in the field of power grid construction.
Generally speaking, power automation can be divided into two aspects: power plant automation and power grid automation. Among them, power grid automation is the current key field of power automation applications, including substation automation, distribution network automation, and dispatch automation systems ; power distribution automation is currently the most popular subdivision field and has the greatest demand for power automation equipment. In terms of power generation automation, due to the country’s increasing emphasis on energy conservation and environmental protection, the power generation process has a trend of shifting from thermal power and hydropower to new energy power generation. The automation technology requirements for new energy power generation are also relatively high, which poses greater challenges to various market participants. . Therefore, the power generation automation market is relatively cold.
Market scale: demand is growing steadily, power distribution occupies the mainstream
The steady growth of downstream demand has boosted the rapid development of the industry; whether power plant automation or power grid automation, the demand for downstream applications has shown a steady growth state, and the growth of downstream application demand has continuously boosted the rapid development of the power automation industry.
In recent years, the country's requirements for power automation systems and intelligent construction have continued to increase, and companies have responded one after another, actively formulating smart grid construction plans, and making a lot of investment. Among them, the automation of power transformation, power distribution and power utilization is the top priority of smart grid construction. The "National Grid Intelligent Planning General Report" planned three stages of grid smart investment, and the demand for automation equipment also followed. The needs of all links of the power industry in my country jointly promote the rapid development of the power automation industry.
National-level policies are frequently issued, which strongly promotes the development of the industry. Since 2006, the state has strongly supported the power industry and the power automation industry, and issued a number of policies to support the continuous development of the power infrastructure and the power automation industry. In particular, the construction of smart grids and distribution networks have made clear instructions for the development of the power automation industry. The 2015 Action Plan for the Construction and Reconstruction of Distribution Networks pointed out to promote the construction of distribution automation and intelligent electricity information collection systems. Realize considerable controllability of the distribution network. In 2017, the "Thirteenth Five-Year Plan for Electric Power Development" pointed out that to promote the construction of distribution automation, according to the different configuration of the power supply area, the overall coverage rate reached 90%, and the distribution network was considerable and controllable. The frequent occurrence of national-level policy planning has strongly promoted the development of the power automation industry.
From the perspective of all aspects of power automation, grid automation is currently a hot field, accounting for more than 80% of the total. Distribution grid automation occupies the lion's share of it, accounting for about 65.20% of the total market scale; followed by substation automation , Occupies 13.80% of the total market size. In power generation automation, hydropower automation has the largest scale, accounting for 6.93% of the total market share. The share of new energy power generation automation has continued to increase, accounting for approximately 2.44% of the market share in 2018.
