Abstract：This paper presents a common reactive power measurement method, discussed various methods using micro-controller feasibility. The paper also introduced the ADI's ADuC812 micro-controller chips, The internal chip integrated analog / digital converter, 16M bytes of addressable data space, and DMA function for reactive power measurement provides a material foundation. Delay measurements using methods and the ADuC812 chip reactive power measurement, it is good value.
