中哈天然气管道压缩机站供电方案分析与应用

Analysis and application of power supply scheme in compressor station of Kazakhstan-China Gas Pipeline

根据中哈天然气管道实际情况,为保证建设工期和运行维护要求,从安全、可靠、实用等角度考虑,哈萨克斯坦压缩机站设计采用天然气发电机、配套自动化控制系统的自发电供电方案。阐述了负荷分析、发电机配置方案、发电站电气主接线方案、电站控制系统(ECS)的应用以及发电站假负载配置等技术要点。该技术极大地保证了电站的可靠性和稳定性。可为今后压缩机站项目自发电电站的设计和运行提供宝贵的经验。

According to the actual situation of Kazakhstan-China Gas Pipeline and in order to ensure the construction period and operation maintenance,the power supply design scheme for compressor stations in Kazakhstan-China Gas Pipeline adopts the natural gas generator and automatic control system for self-generating electricity after considering the safety,reliability,practicability and other factors.This paper illustrates the technical key points including load analysis,generator configuration scheme,power station electrical main wiring scheme,electric control system(ECS)application,dummy load configuration.It provides a strong guarantee for the safe and reliable operation of the power station.
