1. Development characteristics of China's electric power system automation market In the 11th Five-Year Plan and the 12th Five-Year Plan period, the automation development of China's power system market has been the main goal in power grid construction, transformation, and practical application. At present, China's power grid companies have started nearly 100 projects. The construction of basic power grids and comprehensive renovation projects in key cities have made important contributions to strengthening the power supply base, strengthening safe power supply, and accelerating the development of urbanization, automation, reliability, and sustainable development of the power grid. With the full launch of the large-scale urban power grid reconstruction work, the distribution network infrastructure in urban and rural areas in China has also been increasingly perfected, laying a solid foundation for the automation of distribution systems. At the same time, with the establishment of various upgrade network power markets, China's electricity market has become increasingly rich in related demands for automation, and has even shown an explosive growth trend. Therefore, in order to fully meet the market demand and improve the comprehensive competitiveness and adaptability of power companies, we must continue to conduct in-depth research, fully understand the characteristics of the future development trend of China's power system automation market, and develop practical and effective practice programs to eventually make power companies stand firm. The heel has injected new strength into the comprehensive and sustainable development of the electric power system automation market in China. 2. Development Trend and Prospect of Power System Automation Market 2.2.1 Overall Development Trend of Power System Automation Market At present, the automatic control technology in the development of power system market tends to be increasingly optimized for control strategy, showing strong adaptability, perfect coordination control, and intelligent advantages. Obviously, regional distribution is increasingly balanced development trends. At the design level, the power automation system pays more attention to the handling of multi-machine model problems, and extensively uses modern control theory and tools to achieve comprehensive and efficient control. Reasonable introduction of a large number of computer, electronic devices and long-distance communication application technology in the application of practical control means. In the combination of researchers, the power companies emphasize the joint combat model based on multi-functional talents based on the principle of excellence and comprehensive application. In the overall power system, its working methods have evolved from the original open-loop monitoring to the closed-loop control, and the safety and rationality of the high-voltage-level main body to the low-voltage expansion has been realized. For example, the energy management system is allocated to Electric management system changes reasonably. Furthermore, the automation of power systems has achieved a wide range of development from a single component to a part or even a system-wide area, such as the realization of monitoring and control of the entire process, the development of comprehensive data acquisition, and the development of stable control of regional power systems. Correspondingly, its single function also realizes the development of diversified and integrated functions. For example, the integrated substation achieves automatic development and improvement. The system-rich device features are more flexible, faster, and digital. The system relay protection technology has been fully updated and developed. Based on the above trends in innovation, the development goals of the power system automation market have become more optimized, coordinated, and smart. This has made current and excitation control a new round of development research goals for the market. Therefore, we must not only improve the system's safe operation, economical rationality, and high-efficiency scientificity, but also pay attention to the rational transformation of automation services and management, and introduce highly efficient automation service control systems such as management information systems. The road to scientific development in the power system automation market will go even further.
Soluble fertilizer granular include calcium nitrate, Ammonium Sulphate steel grade and caprolactam grade, calcium magnesium nitrate, potassium sulphate. Monband granular fertilizer can add different color and trace elements.
Calcium Nitrate is a kind of green and natural fertilizer. It can improve the quality of soil, change the PH value, reduce the density of active aluminium and loose the soil. It can promote the root, stem, leaf to grow better.
Calcium Magnesium Nitrate is a high nutrition
