    • An integrated excitation and turbine controller (23) for a synchronous generator (20) and a control method thereof are provided. The method comprises following steps: categorizing the fault severity according to the accelerating energy caused by the power mismatch; detecting the generator operation mode according to the signs of power angle derivation and the directions of electromagnetic power; calculating the auxiliary excitation voltage according to the fault severity and the generator operation mode; calculating the auxiliary governor valve opening according to the fault severity and the generator operation mode; and calculating the intercept valve opening according to the fault severity and the generator operation mode. The disturbance severity categorization and the generator operation mode are both considered in the method based on the local measurements (29) so as to determine the best combination of the auxiliary excitation and the turbine control under various system disturbances and operation conditions. The outputs of the integrated excitation and turbine controller (23) will be added into the existing generator controllers for generator transient stability enhancement and dynamic performance improvement. When the disturbances disappear, the outputs of the integrated excitation and turbine controller (23) will be phased out automatically so as to minimize the impacts on the generator steady-state voltage and the frequency regulations.
    • 提供了一种用于同步发电机(20)的集成激励和涡轮机控制器(23)及其控制方法。 该方法包括以下步骤:根据功率失配引起的加速能量对故障严重程度进行分类; 根据功率角推导的标志和电磁方向检测发电机工作模式; 根据故障严重程度和发电机工作模式计算辅助励磁电压; 根据故障严重程度和发电机运行模式计算辅助调节阀开度; 并根据故障严重程度和发电机运行模式计算截流阀开度。 在基于局部测量的方法中考虑了扰动严重性分类和发电机运行模式(29),以便在各种系统扰动和运行条件下确定辅助励磁和涡轮机控制的最佳组合。 集成励磁和涡轮机控制器(23)的输出将被添加到现有的发电机控制器中,用于发电机瞬态稳定性增强和动态性能改进。 当干扰消失时,集成励磁和涡轮机控制器(23)的输出将自动逐步淘汰,以便最小化对发电机稳态电压和频率规定的影响。
