| Abstract: |
| Along with the network reformation,overhead lines are not applicable in urban and industrial area.The wide use of power cable brings forward a new requirement in neutral point earthing mode.In recent years the intelligent earthing compensation device is popular.It remedies the inherent defect of old arc compensation coil and enhances system stability and substation automation level.According to its practical application,three methods of intelligent earthing compensation device in tracking network capacitive current are introduced.They are amplitude of neutral point voltage,phase of neutral point current and additional signal of neutral point.Each of them is evaluated for the further understand of its working principle and application method. |
