| Along with the energy growing tensions, the rational use of energy and energy conservation is a worldwide topic of universal concern, but also human issues of common concern. The induction motor speed control technology has obtained the universal application in national economy each domain. Along with the power system commercialization operation in-depth implementation, saving energy and reducing consumption have become one of the important measures that thermal power plants reduce the cost of power generation and enhance economic efficiency. By adjusting the induction motor operating parameters so as to meet the production requirements, but also achieve the purpose of saving energy and reducing consumption.This article introduced several kind of induction motor speed control technology in the application of Yangliuqing power plant and analyzed the system's security and reliability as well as the energy saving effect before and after the adoption of comparison. The paper introduced emphatically such two motor speed control way as the frequency conversion speed control and the polarity reversal speed control. And the frequency conversion speed control surpasses formerly any speed control way. It is one kind of current internationally utmost benefit, best capability, broad application and best promising motor speed control technology. It adopts computer control technology, electric technology and motor transmission technology to realize stepless speed control of industrial AC motor and has high efficiency, broad range and high precision characteristics.These types of induction motor speed control technology have obtained the good application in Yangliuqing power plant. Through a period of practical operation, the installations have made more obvious effects of energy saving and and more stable operation, and it worth further promoting the application of energy saving transformation work in other power plant. |
