变频调速装置在发电厂辅机电动机的应用

Application of the Frequency Control in Power Plant for Auxiliary Electromotor

详细论述了变频调速的基本原理,从变频调速与风机水泵节能、环境保护的关系及火电厂高压辅机电动机节能降耗的迫切性出发,指出变频调速节能的优越性、巨大潜力及存在的问题。根据经济性原则,提出了几种变频调速节能的实施方案,分析了其优缺点及适用范围。

the fundamental theory of frequency control is discussed particularly. The advantage of saving- energy ,the huge potentiality and the existent problems is indicated from the relation of frequency control and the saving- energy of the water pmnp energy - conservation of the air blower and the protection of environment and the urgency of saving - energy for high voltage auxiliary electromotor in heat - engine plant. Based on the principle of economical efficiency, several actual projects is put forward, and the merits and faults and the applicability is analysed.
