The relay protection and the safe automatic device are guaranteed that the electrical network safe operation,protects the electrical equipment to be exempt from the damage,the major installation which the forestall trouble expands,is the electrical power system essential important component。The relay protection and the safe automatic device's disposition,uses and maintains improper or not the correct movement,will certainly to cause the accident or to make the accident to expand,the damage electrical equipment even causes the electrical power system collapse to disintegrate,therefore to protects and the automatic device principle,the performance,the movement personnel must grasp skilled,and in movement proper operation,careful maintenance。this design unifies Xinjiang Hua Dianhong the wild goose pond power plant 220kV system actual wiring system to carry on the line protective device the design and the related installation computation。Xinjiang Hua Dianhong the wild goose pond power plant 220kV system altogether has four going beyond a line:Two Man Xian (2421),two lines (2422),two grablines (2423),two palace lines (2427),each line disposes WXB-11C and the WXB-15 double draught microcomputer protection。The bypass (2260) protects the disposition logical circuit protection disposition to be the same,but high frequency receives sends a message installs the logical circuit to use in common,when side guides carries on the cut。When normal operation,the double draught microcomputer protection puts the operation。WXB-11C microcomputer protection function:High frequency distance; High frequency zero foreword; Interaction distance; Touchdown distance; Zero foreword; The synthesis is heavy。WXB-15C microcomputer protection function:High frequency negative sequence; High frequency zero foreword; Direction high frequency; Interaction distance; Touchdown distance; Zero foreword; The synthesis is heavy。This design project description key carries on the shaping and the proof to above protection。key word:The relay protection,the safe automatic device,Xinjiang Hua Dianhong the wild goose pond power plant 220kV system,protects carries on the shaping and the proof,
