Practical Application Analysis of Motor Driven Medium Frequency Control Technology
With the progress of the times and the development of social economy, China's power system has developed rapidly, the degree of industrialization and the acceleration of urbanization have made power resources play an increasingly important role in the development of the national economy. The degree of electrification is also used as a very important measure when measuring the level of economic development in a country. The article briefly analyzes the practical application of the frequency conversion speed regulation technology in motor drag, and hopes to provide some valuable reference opinions.
The safe and stable operation of the power system will have a direct impact on people's daily work life and social and economic development. Therefore, relevant departments are paying more and more attention to the safe and reliable operation of the power system. With the continuous development of science and technology, the frequency conversion speed control technology has been rapidly developed and widely applied, and it is applied to the motor drag, which has a series of advantages and values.
1 Frequency Control Technology Overview
Specifically, the frequency conversion speed regulation technology refers to the influence of the motor speed directly affected by the input frequency of the working power supply. The motor speed is appropriately adjusted by changing the frequency of the motor working power supply. With the development of science and technology, it has begun to widely apply variable frequency speed control technology in daily life and work in China. At present, there have been many variable frequency speed control methods, such as direct torque control, vector control and so on. The development of digital control technology and the universal application of semiconductor technology have begun to apply vector control not only in the high-performance range, but also in the field of driving and dedicated driving, and have begun to be widely used in household appliances. Applications, such as inverter air conditioners, refrigerators, etc. In addition, AC drives, such as industrial machines, electric vehicles, etc., have also begun to be used in some other areas.
