This paper designed a kind of phase D-value measuring system based on microchip MCU, which adopted the multi-cycles measuring algorithm to improve the accuracy. This system used the zero crossing point phase detector, hardware and software passed the computer simulation based on PROTEUS and MPLAB, the measuring accuracy satisfied the design requirements, this design thought was successfully applied to smart grid access devices. The simulation and practical results show that compared with the traditional products, the phase D-value measuring system based on microchip MCU has a simple circuit, low power consumption, good real-time, high precision and a wide range of applications, it is easy to implement. In the actual product development, the use of assembly language programming has the better effect than c language programming, and the physical simulation is superior to the software simulation.
