基于DSP的电动机智能保护模块的设计

摘要

The motor is widely used in industrial and agricultural production. With intelligentization and large scale of equipments,the corresponding motor power is more and more high,and the safe operation of motors becomes prior among priori⁃ties in production link. The intelligent motor protection system based on DSP greatly improved the data processing speed,accura⁃cy and reliability of motor protection. The hardware composition,interface connection and software control principle of the motor intelligent protection system are introduced in this paper. The practice proves that the intelligent protection system has the reliabi⁃lity that the conventional relay protection mode does not possess.%在工农业生产中电动机被广泛使用，随着设备的智能化和大型化，相应的电动机功率也越来越高，电动机安全运行成为生产环节的重中之重。基于DSP的电动机智能保护系统极大限度地提高了数据处理速度和准确性，提高了电动机保护的可靠性。在此设计了基于DSP电动机智能保护系统，并详细介绍了该系统的硬件组成、接口连接和软件控制原理。实践证明该智能保护系统对电动机具有常规继电保护所不具备的可靠性。
