Abstract
In order to obtain the effective values of motor sampled signal accurately, for proper protection of motor, this paper introduces a design of motor comprehensive protector based on wavelet analysis. The design includes the motor protection algorithm and key design of hardware and software. On the algorithm side, it uses wavelet analysis, the components of damped DC and noninteger harmonics are restrained by the wavelet analysis. The wavelet analysis remedies the deficiency of Fourier algorithm and provides assurance for motor protection. On the software side, it uses theμC/OS-II operating system and manages every task, so these tasks can work simultaneously and thus the real-time performance of the system is improved. On the hardware side, it designs Ethernet interface to meet the intelligent and networked requirements of motor protection. Practice shows that the protector can realize motor protection effectively, which has certain practical significance.关键词
