Electrical energy serves as the most important secondary energy in production and life, and has played an extremely important role in the modernization of human society. The production and transmission of electrical energy has formed a "electric power industry", its scientific and technical content of operation and management science is rapidly improved; at the same time, electricity production, transmission, use and control equipment are constantly developing or updating, to intelligence Chemical, completed, high-efficiency development, gradually combined with electronic computers, microelectronics, and power technology, form new types of electrical technology and equipment, and electrical engineering in the national economy, the development of science and technology is growing more and more important. Role.

Electrical engineering domains mainly include electrical energy production, transmission, and use of power systems, power system security, reliable, economical operation, design, manufacturing, operation, measurement and control of various types of electrical equipment and systems. Equal related aspects of engineering technology. The fields of this engineering and electronic and electronic and communication engineering, computer technology, control engineering, material engineering, mechanical engineering, instrumentation engineering, power engineering and other engineering are closely related.

Power System

This article is based on the stable control of the system, combined with the research project of a new generation of intelligent low-voltage low-voltage load devices, and studies the relevant fields and puts forward new ideas. Layd the foundation for a more in-depth study.

This paper summarizes the research status of safe and stable control of power system, from two aspects of control theory and control measures (devices), the main research results at home and abroad. Finally, the development trend of safe and stable control technology is briefly introduced.

Power System Transient Energy Function Direct Law After years of research, significant progress has been made, and it has become an important aid method for time domain analysis. The second chapter of this paper introduces the basic theories and methods of transient energy function, focusing on the EEAC method and its application in stable cutoff control. Further practical use requires a lot of work.

Development prospects

Multi-machine system frequency dynamic process is an important basis for the design of low frequency load schemes. This article adds generators and load frequencies on the basis of the original linear disturbance model. The impact of regulating effects and carried out system simulation research. At the same time, according to the characteristics and simulation results of the multi-machine model, a new-speed reduction design and a new plan based on a multi-machine system is proposed, and the program has improved the adaptability of low frequency reduction performance and system operation mode compared to traditional programs.

As an implementation of the program, the author of this article developed a new generation of microcomputer intelligent low-voltage low voltage load devices as one of the main developers. The fourth chapter detail the improved software frequency frequency range, according to the implementation method, soft and hardware structure, etc. of the power value, soft, hardware structure, and other key technical measures. Finally, the dynamic model of the device is given.
