Abstract This paper takes a 110kV system as the protected object and equip relay protection for it and set protection parameters.These protections include the 10kV line’s overcurrent protection with stage, the main transformer’s protection and the 110kV line’s distance protection with stage. The problem of cooperating between various kinds of protections for adjacent components in a system is properly disposed so that they can work together well.
