基于预制舱的配送式智能变电站设计

针对目前电网建设难度加大,变电站建设周期压缩,生态环境对变电站建设工地的环保措施要求愈来愈严及变电站设备智能化、精细化程度不断提高导致现场施工愈加困难等一系列问题,提出了一种基于预制舱的配送式智能变电站建设模式,分析了该模式变电站的特点,阐述了其设计方案.根据智能变电站的特点,将变电站分为智能一次设备和集成二次设备的预制舱,两者之间通过预制光缆、电缆连接,对预制舱结构及舱内设备布置、接线、运行环境的设计方案进行了讨论,结合工程实例给出了具体实施方案和技术经济效益分析,为今后基于预制舱的配送式智能变电站建设提供了参考与借鉴.

Distribution-mode Smart Substation Design Based on Prefabricated Cabin

Considering the difficulty in current power grid construction, the compression of construction cycle, the more restricted environmental requirement and the increasingly intelligent and fineness of substation equipment, this paper proposes a construction model of distribution-mode smart substation based on the prefabricated cabin. The characteristics of this model is analyzed, and the design scheme is introduced. The smart substation includes two parts： the intelligent primary equipment and prefabricated cabin which integrated with secondary equipment. The two parts are connected with prefabricated cables and prefabricated fiber optic cables. Besides, in this paper, the structure, the inner layout and the wiring and operation environment of prefabricated cabin are discussed. In the end, the concrete implementation of the method is provided. Also, the analysis of technical and economic significance combining with practical engineering applications is presented, which provides reference for future prefabricated cabin based smart substation construction.
