摘　　要：应急发电机组是海上油气田生产平台上必不可少的设备,对于保障平台上人员与设备的安全有着重要作用.简要介绍BZ26-3 WHPA平台应急发电机组控制系统的主要构成及控制原理,重点分析了该机组控制系统主要控制电路,包括机组启动/停机、调速、百叶窗等控制电路,为应急发电机控制系统的研究、海上平台应急发电机的调试与维护提供参考。本地控制采用康明斯发动机自带的KCM—IIA型机旁控制箱,带有AUTO-3型自启动板和发动机调速板.远程控制盘选用西门子S7-200可编程控制器和外围继电器电路构成。控制系统的硬件设置及功能布局合理,符合相关标准和规格书的要求。Emergency generator set is a necessary equipment of offshore oilfield platform. It has a significant function in ensuring the safety of people and equipments on the platform. The paper describes the composing and control principle of the emergency generator set BZ26-3 WHPA briefly, and especially analyzes the main control circuit of this control system including start/stop control circuit, engine speedadjustment and louver control circuit. This paper can supply references to research on emergency generator control system, commissioning and maintenance of emergency generator set. For local control panel, KCM--Ⅱ A local controller is chosen, including AUTO-3 start board and electronic governor. The remote control panel is composed of SIEMENS S7-200 PLC and relay control circuit. Hardware and function of this control system is reasonable, and satisfies the requirement of criterion and specification.
