Abstract：This paper gives a detailed analysis of pole 1 low valve group protection system broke DC overvoltage protection one-level action during the pole 1 double valve group open line test block process without DC line in UHVDC Chuxiong-Suidong HVDC project based on SIMATIC-TDC, the optimization scheme is presented for the inherent DC overvoltage protection action during the open line test block process of UHVDC based on SIMATIC-TDC, and through DC open line test simulation test was carried out by means of the real time digital simulation platform in UHVDC Chuxiong-Suidong HVDC project, this scheme effectively solves the DC voltage protection action during the open line test block process , the feasibility of the optimization scheme is verified, and in the upcoming DC control and protection software to be implemented in the optimization of UHVDC Chuxiong-Suidong HVDC project and Puer-Qiaoxiang HVDC project based on SIMATIC-TDC.
