The Research Of New Electric Quality Monitoring Equipment Based On DSP

Now the electric quality problem is hot in the electric industry. This thesis firstly reviews the development of electric quality monitoring field in the world, summarizes the problem that occur in the electric quality monitoring and its resolvent, and then roundly expounds the definition, harm and measuring arithmetic. It introduces the analysis method based on wavelet theory, which is applied on short duration power quality disturbance such as voltage sags and so on. The program was writed in C language based on Lacunaris Algorithm, and was validated by Matlab. This is the base of the equipment's development. Finally the software and hardware developing method of the electric quality monitoring equipment based on DSP is introduced. The future of the electric quality monitoring research is prospected.
