变频电动执行机构在火电厂中的应用

Application of Frequency Conversion Electric Actuator in Thermal Power Plant

变频调速技术是20世纪80年代初逐渐发展起来的技术,该技术的出现为开创全新智能电机时代打下了良好的基础。总的来说,变频调速技术改变了以往普通电动机仅能定速运行的模式,促使电动机与相关推动负载可在无任何改动情况下根据生产工艺需求调整转速并输出,这样可减少功率损耗而实现高效运行。变频调速技术有很多控制形式,其中矢量控制应用范围十分广泛,一些高性能与专业驱动领域中均有涉及,比如变频冰箱与空调等。基于变频调速技术的应用十分广泛,为此加强其在电机拖动中的应用研究就显得十分必要,本文展开了分析,希望相关事业有所借鉴。

Variable frequency speed regulation technology was developed gradually in the early 1980 s. The emergence of this technology has laid a good foundation for creating a new era of intelligent motor. In general, VVVF technology has changed the previous general motors can only speed the mode of operation, the motor and drive the load in the relevant circumstances without any changes according to the requirements of production process to adjust the speed and output, this can reduce the power loss and achieve efficient operation. Variable frequency speed control technology has many forms of control, in which vector control applications are very extensive, and some high performance and professional drive areas are involved, such as frequency conversion refrigerators and air conditioning, etc.. The application of variable frequency speed control technology is very extensive, so it is necessary to strengthen its application in motor drive. This paper analyzes and hopes to draw lessons from relevant business.
