摘要
针对目前抽油机变频改造存在的问题,该文从理论上分析了AFE技术的原理、控制特点及有关技术参数的设置方法;详细阐述了AFE技术改善变频器性能,提高抽油机效率,节约电能以及推广应用的现实意义。
According to the porblems existing in the reformation of frequency converters for use with an oil pumping set, the paper makes a theoretic analysis of the AFE technology, control characteristics and the method to set technical parameters. The AFE can improve the performance of a frecuency converter, increase the efficiency of an oil pumping set and save energy. The significance of its application is also described.
