Algorithm Design for the Different Programs of HVDC Control and Protection

As the core of HVDC(High Voltage Direct Current) project., the control and protection program is the key to the engineering upgrade and transformation process. The lack of a visual analysis and description method for differences before and after page modification in program. Modification can only be verified through program modification form filled out by engineering personnel., which can easily lead to inconsistencies such as omissions and errors. This article is based on the HCM3000 DC control and protection platform., and designs a analysis algorithm for different programs of the control and protection. By parsing the application files of the control and protection program., a class multiple linked list is generated., and data processing is performed to generate a binary decomposition tree structure. Then., node matching is performed on the data structure chain based on the binary decomposition tree to ultimately achieve differential information comparison and ensure the accuracy of the control and protection program on the engineering site. The developed software has been applied in HVDC projects., greatly improving the reliability of project operation.
