Research Of Voltage Harmonic Monitoring And Elimination Device Based On ARM

With the power of the development of electronic technology, harmonic pollution in electrical power system becomes more and more serious, has become the network of"public hazard". As a consequence to monitor and study power network is not only a premise to confine and eliminate also an urgently demand to assure power supply system to run safely and economically and devices and personal safety. Based on the analysis of harmonic detection technology at home and abroad Based on the analysis of harmonic detection technology at home and abroad on the status and development direction of the foundation, the design of Research of voltage harmonic monitoring and elimination device Based on ARM7 was introduced, the chip STR710 as core processor was chosen, using the periphery chip such as CS8900A,bidirectional triode thyristor and so on, then hardware of voltage harmonic monitoring Based on ARM7 is designed and accomplished, and simultaneously using FFT algorithm to realize harmonic monitoring and simulation under IAR EWARM 4.13 environment. At last the design and realize of the embedded internet interface based on ARM is discussed.
