| Abstract:Using ETAP power system analysis and calculation application software as an auxiliary tool, based on the supporting equipment NANRI comprehensive protection measurement and control device of this project, the relay protection setting calculation of various types of electrical equipments and generators in the 10 kV auxiliary power system was discussed with the auxiliary power medium voltage system for self-contained thermal power station of a large domestic pulp mill as an object in this study. The optimal scheme of relay protection setting was sought while met the four basic requirements of relay protection setting. |
