Abstract: Provided are a method and apparatus for determining a blockage of a filter of a clothes dryer and a clothes dryer. The clothes dryer includes a motor. The method includes following steps. An actual rotational speed of the motor is acquired, and an electrical parameter corresponding to a rotational speed range to which the actual rotational speed belongs is determined as a first threshold corresponding to the actual rotational speed; an actual clothes volume in the clothes dryer is acquired, and the first threshold is corrected according to a correction coefficient corresponding to a clothes volume range to which the actual clothes volume belongs so that a second threshold is obtained; and an actual electrical parameter of the motor is acquired, and when it is detected that the actual electrical parameter is less than the second threshold, it is determined that the filter of the clothes dryer is blocked.

Abstract: Systems and methods for improved anomaly detection for rotating machines. An example method may include determining that power generation is to be performed based on a voltage instead of a power factor; receiving a command voltage; receiving a measured voltage value from a first location in a power generation network; determining that the measured voltage value from the first location is less than the command voltage value; determining that a current value associated with a transmission line at the third location is less than a threshold current value; determining that a reactive power of a power generation component at a third location is less than a maximum reactive power of the component; and increasing, based on the determination that the reactive power of the component at the third location is less than a maximum reactive power of the component, the reactive power of the component.
