Discussion on the Calculation of Setting for Transmission Lines Merged into the Main Power Grid |
| |
| Abstract: | Large numbers of small power stations having been merged into the main power grid through the bus of 35KV、10KV and 6KV in 220KV, 110KV or 35KV substations. These years, some small power stations are even merged into the main power grid through 10KV switching houses. According to this situation, based on the condition of Jinan Power Grid, combining several typical cases, the calculation principles and the methods of solving some special problems in relay protection setting are introduced. |
