摘要
根据闭环电力系统发电机组保护要求,分析半潜式钻井平台闭环电力系统中发动机调速器故障和发电机自动电压调节器故障对电网的影响,针对两种故障分别进行发电机组的主保护设计和备用保护设计,给出各种故障判断依据和保护设计参数设定示例,为半潜式钻井平台闭环电力系统发电机组保护设计和应用提供参考。
Based on the generator protection requirement in the closed bus-ties mode of operation,the effects of the engine governor and generator Automatic Voltage Regulator(AVR)failures on the power system of semi-submersible drilling platform are analyzed.The design of main and backup protection is introduced for the two types of failures.The judgment basis of various failures and setting examples of protection design parameters are given.The study provides reference for the design and application of the generator protection system for the semi-submersible drilling platform in the closed bus-ties mode of operation.
