| Abstract: |
| According to the real conditions of Yunnan power network, the calculation principles for relay protection setting which should be observed are introduced. They are applied for the setting of high frequency protection, three section distance protection, four section zero sequence protection, single and three phase auto reclosing protection, current instant trip protection, breaker failure protection and position inconsistency protection for circuit breakers on three phases, which are widely used in 220 kV lines of power network. The measures to solve the problems during setting calculation are also presented. |
