摘要： Systems and methods to control power plant operation via control of turbine run-up and acceleration are disclosed. According to one embodiment of the disclosure, a method of controlling a turbine in a power plant can be provided. The method may include receiving an operating pressure of a condenser associated with a power plant; receiving a rotor speed of a turbine associated with the power plant; receiving a last stage blade (LSB) protection limit for the turbine; based at least in part on the operating pressure of the condenser, the rotor speed of the turbine, and the LSB protection limit, allowing, via a control system, a run-up of the turbine. The method may further include: receiving a rotor speed gradient of the turbine; receiving one or more critical speed ranges associated with the rotor speed of the turbine; and based at least in part on the operating pressure of the condenser, the rotor speed, the rotor speed gradient, and the one or more critical speed ranges, regulating, via the control system, at least one of: the rotor speed of the turbine and the rotor speed gradient of the turbine.
