| Abstract: | Traditional methods for Petersen coil resonance adjustment and feeder earth fault identification in compensated network are introduced.All this methods hardly satisfy the requirement of distribution system automation.A new method for Petersen coil automation tuning is developed,which is based on measuring the system resonance frequency and parameters to the ground, and a new method for faulted feeder identification is also presented,which is based on measuring the zero sequence current variation caused by shut-cutting the neutral earthed resistance.The devices for Petersen-coil tuning and fault identification have been developed and applied in distribution networks throughout China for many years. |
