Modern type of AC Drive System

Exchange into a modern AC motor speed control system, power electronic power converters, controllers and four major detector components. In accordance with the object of different types of AC motor, speed of modern communication systems can be divided into induction motor and synchronous motor drives. Here are introduced the system of induction motor.

1.1 induction motor speed control system of the basic types of

By the induction motor working principle, we can see that from the stator into

p=(1-s)M p is the effective electromagnetic power can be divided into two parts: m

p=s M p and s is power load drag; another part of the deterioration of quality of power s

proportional to slip . How to deal with deterioration of quality of power is consumed or feedback to the grid, and measurable system of induction motor efficiency. Therefore by poor power to the different treatment of modern induction motor can be divided into three types of speed control system.

(1) power consumption and deterioration of quality-based speed control system

Poor power switch are converted to the form of calories consumed. Thyristor Surge speed fall into this category. In the induction motor speed control system, the minimum efficiency of such systems is to increase power consumption and deterioration of quality in exchange for the cost of lower speed.

(2) to poor power feedback-based speed control system

To deteriorate to a small portion of power consumed by the majority of variable flow control devices to the power grid feedback. Lower speed, more power to repay. Wound cascade induction motor speed and doubly-fed fall into this category.

(3) to deteriorate to the same power-based speed control system

And deterioration of quality of power in the rotor part of the consumption of copper loss is inevitable, but in such systems, both high and low speed, power consumption and deterioration of quality is essentially the same, therefore high efficiency. VVVF fall into this category. AC Drive System is currently in, the application of a maximum of VVVF, the most extensive, can constitute a high dynamic performance of AC Drive System to replace the DC drive.

1.2 AC speed control system of modern development trends and developments

Looking at the speed of development of the exchange process and the status quo, we can see that speed of modern communication technology trends and future development trends.

(1) to replace the DC drive system for the purpose of exchange of high-performance
