Study On Analysis System Of Power Quality

This thesis opens up the power quality analysis system according on practice request. Basing on country standard on power quality description mark and traditional continual system's theory, introduces into digital compute methods and mends some of them. Each compute method has been simulated by using Matlab. The simulated result shows WT can be used to recognize transient disturbance in power quality analysis system and divide a signal from mixed signal, which is mixed with noise. The simulation result also shows FFT can be used to analyses steady disturbance signal.In the following, according on system requestment,which includes high speed MCU, steady system , good real time, favorite communication interface, good interface, development easy and good extension, analyses and selects MCU, hardware platform and software develop platform, get the scheme of power quality analysis system, which is using Visual C#.Net develop Windows CE user program on R_Tech hardware platform.This thesis realizes the development of power quality analysis system on hardware platform and the simulation system on PC. Use the simulation system to test the analysis system. The test result show the result of analysis system is the same as the result of real continual system, so we get that the analysis system can correctly show the reality power quality.
