摘　　要：本文以某型三轴燃气轮机发电模块为研究对象,该发电模块是由某型三轴燃气轮机作为原动机以十二相同步整流发电机作为能量转换装置对外输出电能。通过Matlab\Simulink仿真平台建立发电模块仿真模型,并基于罗克韦尔PLC控制系统和ADI仿真系统搭建所需的半物理仿真平台,仿真研究发电模块的动态特性,制定发电模块在不同运行状态下的转速控制策略。文中针对燃气轮机发电模块在不同工况下负荷突变的不同情况进行仿真研究,分析比较几种转速控制方案在发电模块不同运行状态下的控制品质,结合几种控制方案的优点制定最优的转速控制策略。With the power generation module in a three-shaft gas turbine serving as the object of study and the three-shaft gas turbine as the primer mover,a twelve-phase synchronous power generator serves as the energy conversion device to give a power output to the outside world. Through a Matlab \ Simulink simulation platform,a model for simulating power generation modules was established and on the basis of a Rockwell PLC control system and a ADI simulation system,a semi-physic simulation platform was also set up as necessary to simulate and study the dynamic characteristics of power generation modules and formulate the rotating speed control strategies for the power generation modules in various operation states. Furthermore,a simulation and study were made of various conditions of the power generation module in the gas turbine when the load underwent an abrupt change under various operating conditions and the control quality of several rotating speed control versions were analyzed and compared when the power generation module was in various operating states and in combination with the merits of the control versions above-mentioned,optimum rotating speed control strategies were worked out.
