锦州25—1南油气田主电站的选型设计

主电站作为海洋石油开采平台最重要的核心组成，为整个平台提供动力来源，是保证平台能够正常运转的心脏器官。从机组类型、特点，以及相应的工作原理等几个方面对海洋石油开采平台上的主电站作了简要的描述；依据相关基础数据，结合锦州25—1南油气田的特点，对油气田进行了电负荷分析，得出油气田设计所需要的典型电负荷量以及相关的数据；通过对机组容量、负荷率、备用率、机组占用平台面积、机组重量等几个参数的比对，从往复式发动机电站机组和燃气透平机电站机组中优选出了主电站机组方案。通过对锦州25—1南油气田主电站方案优选的详细阐述，为海洋石油开采平台主电站的选型设计提供参考和借鉴。

Selection and design of the main power station in JZ 25 - 1S oil/gas field

The main power station is the most significant part on offshore oil platform because of its vital function of power generating performance. Firstly, this paper briefly describes the main power station on offshore oil platforms in several aspects, such as set type, characteristics and working principle or concept, etc. Secondly, considering the characteristics of JZ 25 - 1S oil/gas field, analysis and calculation of electrical power consumption was carried out based on the relative data of the oil/gas filed, therefore the typical electrical power consumption and correlative data necessary for the design and selection of main power station was acquired. At last, the main power station plan of JZ 25 - 1S oil/gas field is chosen from reciprocating engine driven generator sets and gas turbine generator sets by comparing parameters, such as unit capability, load bearing capacity, standby rate, weight and platform space situation, etc. The design and selection process of main power station has been deeply discussed and detailed plan for JZ 25 - 1S oil field development project has been presented in this paper which provides a good reference for the design and selection of main power station on offshore oil platforms.
