| Abstract: | The substation of port area supplies electricity by multi-cables to portal crane, arouses high frequency resonance of the system and influences normal supply of the grid, which should be harnessed. The principle and characteristics of high frequency resonance of system is introduced. The imitating analysis of high frequency resonance of supply system is analyzed. The harness plan for eliminating high frequency resonance is put forward which has significance. |
