【摘要】 立足于研究水轮机组调速系统模型与参数对电网阻尼影响。在开展水轮机组调速系统建模试验的基础上,研究调速系统各个环节的传递函数,通过对单机无穷大系统动态过程的理论分析,指出了水轮机组调速系统提供正阻尼的条件。BPA仿真与相关计算证明了理论分析的正确性。更多还原

【Abstract】 The aim of this paper is to research Effect of Hydraulic Turbine Speed Control System on Damping of Power Grid.Based on the results of mover-governor modeling,transfer functions of all sections of Speed Control System are built.The conditions of positive damping are presented by analyzing the dynamic characteristic of single-machine infinite-bus system in theory.Results of BPA Simulation show that the theory is correct.更多还原
