浅析变频技术在热电厂的应用

Discussion on application of transducer in Yinchuan Cogeneration Power Plant

随着电力电子器件、微电子技术、电动机和控制理论、计算机技术、自动控制技术的发展,近年来交流电动机调速系统也有了很大的发展。微型计算机、矢量变换控制技术在高性能交流传动系统中取得了根本性的突破,由于节能效果明显,已大量采用交流调速系统。银川热电厂应用大功率变频器对热网循环水泵进行变频器控制,达到了调速操作简单和节能的目的。

with the development of power electronic apparatus, micro-electronics technology, eleetromotor and automatic control technology, the AC electromotor timing system is also developing recently .The microcomputer and vector converting control theory make ultimately surmount in high-capability AC transmission system. Now AC timing system is often taken to save energy. On the base of applying big power transducer in Yinchuan Cogeneratian Power Plant, introduces the principle of three -phase bridge rectification, DC-AC converter, vector converting control theory of asynchronous motor in order to popularize this technology applying in power plant.
