动力定位船闭环电网故障穿越功能实现方法探究

为更好地实现动力定位船舶在运营过程中的节能减排,越来越多的动力定位船舶在电站设计中选择使用闭合母联型电力系统。ABS、DNV·GL、CCS等船级社均在规范或指南中提出闭合母联型电力系统的设计检验要求,其中低电压故障穿越能力是各船级社对闭环电网可靠性考核的重点之一。文章由各船级社对动力定位船舶闭合母联型电力系统的规范要求入手,结合计算机仿真实验分析电力系统故障穿越功能的设计要点,并在此基础上对该功能的实现方法进行探究。

Implementation of Fault Ride Through Function of Closed-Loop Power Grid for Dynamically Positioned Vessel

The closed bus-site power system has been increasingly used in the design of the power station on the dynamically positioned vessel for the energy conservation and emission reduction during their operation.The design and inspection requirements of the closed bus-tie power system are put forward in the rules or guidelines of ABS,DNV-GL,CCS and other classifi cation societies.Among them,the low-voltage fault ride through capability is one of the key points in the reliability assessment of the closed bus-tie power system by the classifi cation societies.The design points of the fault ride through the function are analyzed from the requirements of the closed bus-tie power system by the classifi cation societies,combining with the numerical simulation experiment.On this basis,the implementation of the fault ride through the function is explored.
