    • Systems and methods for providing override control for a feedwater pump recirculation valve 140 are provided. According to one embodiment, a system may include a controller 600 and a processor communicatively coupled to the controller 600. The processor may be configured to receive one or more measurements associated with pump motor power driving feedwater pump flow. The feedwater pump recirculation valve 140 may be configured to maintain a predetermined minimum recirculation flowthrough the feedwater pump 105 by regulating recirculation pump flow through a recirculation line. The processor may be also configured to calculate, based at least in part on the one or more measurements, the recirculation pump flow, and compare the recirculation pump flow to the predetermined minimum recirculation flow. Based at least in part on the comparing, the processor may selectively provide an override control signal to the feedwater pump recirculation valve 140 to selectively modify the recirculation pump flow.
    • 提供了用于对一个给水泵再循环阀140提供超驰控制的系统和方法。 。根据一个实施例,系统可以包括控制器600和通信地耦合到控制器600的处理器可以被配置为接收与泵电动机功率驱动给水泵流相关联的一个或多个测量的处理器。 给水泵再循环阀140可配置成通过通过再循环管线的调节再循环泵流量,以保持通过给水泵105的预定最小再循环流量。 该处理器可以被如此配置,以计算,至少基于在所述一个或多个测量值,所述再循环泵流量的一部分,并比较所述再循环泵流量与所述预定最小再循环流量。 至少部分地基于所述比较部中,处理器可以选择性地提供,以覆盖控制信号到给水泵再循环阀140,以选择性地改变所述再循环泵流量。
