Abstract：In order to eliminate the “error of relay protection setting” of factors, improve the protection setting value calculation accuracy, solution is to design a set of automatic protection setting value calculation tool to replace the manual operation. It uses EXCEL electronic form software as a platform, based on the database content, in order to protect the value generation calculation program and calibration program as the core, to maintain the basic data as a fixed value calculation of the trigger condition, in the maintenance of the basic data that has been generated automatically actuarial reference value; input value data, immediately given the fixed value to performance analysis and evaluation of results.
