| Abstract: | In this paper,power quality of power grid is discussed refer to national standard,power quality specification and usual arithmetic are put forward.A real time on-line power quality monitoring system was designed,which based on industrial level controller ARM9.According to the designed system,128 synchronous samples was fulfilled per 20ms,FFT method was adopted to calculate the harmonic rate within 63th harmonic and the power quality specification.Interface of TCP/IP was also designed to make a web monitoring system of power quality.The testing results of the designed system show that the power quality on-line monitoring system has high performance. |
