用于电力系统仿真的联合循环电站动态模型

从控制流程角度建立了一个适当简化的联合循环电站系统模型,目的在于为电力系统的实时仿真提供一个重要的组成模块。将该模型与电力网络结合,采用专业软件进行模拟,以研究整个电力系统的动态特性,为提高系统的安全性和稳定性提供理论依据。设计了一个P ID控制器,以提高系统的稳定性能。将该模型加入到一个虚拟的两区域电力系统中,采用专业软件N etom ac进行仿真,运行结果证明该模型可以用于实时仿真实验,并且验证了P ID控制器有助于提高系统的稳定性。

Dynamic modeling of combined cycle power plants in power system simulations

This paper presents a simplified combined-cycle power plant module for use in a real-time power system simulation.The module was combined with a power network system model in a simulation using the commercial simulation software Netomac to study dynamic system characteristics and enhance system security and stability.A PID controller was used to improve the system stability.The simulation of a two-region power system is very effective and shows that the PID controller is needed to enhance the system stability.
