摘要
摘要:介绍了燃气轮机发电机组及其励磁系统和调速系统的数学模型,并在MATLAB中建立了燃气轮机励磁系统的仿真模型,对其动态特性进行了仿真计算。利用电力系统分析综合程序(PSASP 6.1版)建立了燃气轮机励磁系统及调速系统的用户自定义模型,并结合典型配电网,对并网后的燃气轮机进行了暂态分析和小干扰稳定分析计算,分析了励磁系统及调速系统的有关参数对燃气轮机动态特性的影响,为研究分布式电源对电力系统暂态特性的影响奠定了基础。
The mathematical model of gas turbine generating sets with excitation system and governor system is presented, the simulation model of the excitation system is established in MATLAB and its dynamic performance is analyzed. The User-Defined Model of excitation system and governor system is also established by use of Power System Analysis Software Package (PSASP 6.1). The transient performance and small signal stability of gas turbine generating sets connected to a typical distribution network are calculated and analyzed. The influences of related parameters of excitation system and governor systems on dynamic performance of gas turbine are analyzed, so the foundation is lain for studying the influences of distributed generation on transient performance of power system.
