An Application Scheme of Low Cost Synchronous Phasor Measurement Device Based on SCM630

Under the dual carbon target, a new type of power system dominated by new energy is rapidly developing, exhibiting characteristics such as high proportion of new energy generation, high degree of power electronicization, and high coupling between AC and DC, leading to the continuous expansion of distribution network scale and increasing complexity. Its operating status directly affects the stability and safety of the power system. Therefore, How to ensure the safe and stable operation of the distribution network is a hot research topic and an urgent problem that needs to be solved. With the continuous in-depth research and exploration of synchronous vector measurement equipment by major universities and research institutions, the hardware solutions and software algorithms for detection have become more perfect and stable. However, due to the high hardware cost of the current solution, it is difficult to achieve large-scale application in the field of power distribution, This article proposes a low-cost synchronous phasor measurement device designed for distribution networks based on the main control chip (SCM630) of Beijing Smart-chip Microelectronics Technology Co., Ltd., which is equipped with a synchronous clock chip and a high-precision AD sampling chip. The device aims to improve the perception and active control capabilities of distribution network operation, ensure the safe and reliable operation of distribution networks, and provide fault diagnosis and parameter identification for distribution networks Dynamic control and other necessary preparations are provided.
