海港吊机供电系统高频谐振与治理

摘要

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.%海港地区变电站通过多路电缆向码头吊机供电，引起系统高频谐振，影响电网正常供电，必须予以治理。介绍系统高频谐振发生的机理与特点，进行供电系统高频谐振仿真分析。提出消除系统高频谐振的治理方案。该方案对消除谐振有实际意义。
