摘要
以珠海港高栏港区集装箱码头二期工程岸电项目为例,介绍该项目采用的船舶岸基电源系统的设计及应用。该系统由配电系统、变频变压电源系统及岸电接电箱三部分组成,其核心是两台2 MVA可移动式变频变压电源系统,通过并联可达4 MVA。分析其系统结构设计、变频变压电源技术特点、供电方案及连船测试情况。经实际测试,该岸电系统输出电压总谐波畸变率、频率稳定性、变压器温升等指标均达到设计要求,验证了该船舶岸电系统方案的可靠性。
Taking the Project Phase II shore power of Gaolan container terminal of Zhuhai port as an example,the design and application of ship shore-based power system used in the project are introduced.The system consists of distribution system,VFVV power system and shore power connection box.Its core is two 2 MVA mobile VFVV power systems,which can reach 4 MVA through parallel connection.The system structural design,technical characteristics of VFVV power supply,power supply scheme and ship connection test are analyzed.The actual test shows that the total harmonic distortion rate of output voltage,frequency stability and transformer temperature rise of the shore power system meet the design requirements,which verifies the reliability of the ship’s shore power system scheme.
