【摘要】 电力系统是一个强非线性系统,电力系统稳定性一旦遭到破坏,必将造成巨大的经济损失和灾难性后果。发电厂中的锅炉-汽轮机-发电机是一个整体,它们是高度耦合在一起的,由于三者综合控制系统的复杂性,所以在这方面的研究还很少。本文采用线性最优控制方法对锅炉-汽轮机-发电机三者综合一体化控制进行了初步的研究,设计了机炉电综合最优控制规律,并且以200MW机组模型为例,用MATLAB/Simulink对此控制系统进行了仿真分析,结果表明该设计方法是可行、有效的。最后,介绍了MATLAB中的SimPowerSystems模块库,并用其建立了一个非线性的单机无穷大系统,将汽门-励磁最优综合控制器应用于其中,对综合控制进行了进一步的研究。更多还原

【Abstract】 The electric power system is a strong nonlinear system. Once its stability is destroyed, there must be huge economic losses and catastrophes. In the power plants, the boiler-turbine-generator as a whole is an integrated unit and their dynamics are highly coupled together. The control design based on the boiler-turbine-generator dynamics has not been considered due to their complexity. Using linear optimal control strategy, this paper studied integrated control of boiler-turbine-generator, designed optimal control law of integrated control of turbine, boiler and generator. Furthermore, control system of a 200 MW thermoelectric generation unit was simulated by MATLAB/Simulink. The result showed that this design method is feasible and effective. Finally, introducing the SimPowerSystems module of MATLAB, and a nonlinear one machine and infinite bus system was established through SimPowerSystems, optimal valve-excitation control was applied in it and making a further study of integrated control.更多还原
