摘要
汽轮发电机组调速系统是一个多变量、强耦合的非线性系统,是机组参与一次调频的主体,基于对汽轮机调速系统线性模型的分析,提出了通过多工况扰动试验,引入“汽轮机调速系统协同曲线”的方法,改善了模型在多工况范围内对机组功频特性的适用性.
Abstract
Turbine speed control system is a multi-variable,strong-coupling nonlinear system,and the main unit involved in primary frequency regulation.Based on the analysis of the linear model of the turbine speed control system,this paper proposes conducting the multi-condition disturbance test,and introducing "turbine governing system collaboration curve ",which has improved the applicability of the model to the unit power-frequency characteristics in various working conditions.
