摘　　要：在某海上平台中压配电系统中,货油泵经常意外跳闸,影响原油外输作业的稳定,易造成安全隐患。对故障进行分析后,决定采用新型综合保护装置取代发生故障的老旧装置。为此,对新型综合保护装置的硬件性能,即端口要求、保护功能及通信兼容性进行设计;利用上位机对综合保护装置的保护参数、逻辑参数、I/O参数、通信参数进行重新配置;对中控系统与综保通信的PLC通信程序重新进行设计与编程,解决通信兼容性问题;结合新型综合保护装置的端口功能,对电动机的继电控制电路重新进行设计与安装,完成综合保护装置的换型工作。该方案的实施为油田配电系统老旧设备换型提供了经验与借鉴。In the medium voltage power distribution system of an offshore platform,the cargo oil pump often has unexpected trip,which affects the stability of crude oil export operation and causes security risks.After analyzing the fault,it was decided to use a new integrated protection device to replace the faulty old device.The hardware performance of the new integrated protection device was designed,including port requirements,protection function and communication compatibility.The protection parameters,logic parameters,I/O parameters and communication parameters of the integrated protection device were reconfigured by the host computer.The PLC communication program of the central control system and the comprehensive insurance communication was redesigned and programmed to solve the problem of communication compatibility.Combined with the port function of the new integrated protection device,the relay control circuit of the motor was redesigned and installed,and the replacement of the integrated protection device was completed.The implementation of this scheme provides experience and reference for the replacement of the old equipment in the oilfield power distribution system.
