Research on the Design Scheme of Wide Area Synchronous Phasor Measurement System for Smart Distribution Grid

  Introduction  With the access of large-scale distributed generation and flexible load in distribution network， the accuracy and speed of traditional terminal measurement are difficult to meet the actual needs， while the new generation of distribution micro synchronous phasor measurement unit （D-PMU） is an important way to solve the above problems.

  Method  Firstly， the working principle and application of D-PMU were analyzed； secondly， the synchronized phasor measurement system of distribution network and its installation and deployment scheme were proposed； then， according to the requirements of the demonstration area， the architecture and deployment scheme of wide area measurement and control system of distribution network were proposed； finally， the application of D-PMU in intelligent distribution network was summarized.

  Results  The effectiveness of the demonstration construction verifies the feasibility and economy of the key technology and design scheme developed by the project.

  Conclusion  It provides rich engineering experience for the further integration and promotion of D-PMU with other traditional fields of distribution network.
