| Abstract: |
| Rational configuration of protection relay and safety equipment is important to substation operation reliability and power network safety. Combined with actual conditions of power network and based on author's operation experiences, the configuration principle of protection relay and safety equipment and its reason are discussed for the special main lines of 220 kV Shi?Zhong substation. A few actual problems of relay configuration are discussed in detail and the relay actions seriously analyzed. The configuration principle proposed is reasonable,comprehensive and relative to actual conditions, and it is of certain value to protection workers. |
