【 摘 要 】

Based on classical analytical process of cylinder efficiency, the mechanism of efficiency change during turbo-generator power adjustment is revealed, and the influence of cylinder efficiency change on calculation of generator loading limit is studied and tested by using PSCAD software. The result indicates that, efficiency deviation caused by sudden load is helpful for the recovery of system power balance, and that the negligence of power deviation caused by efficiency decrease under overload circumstances may reverse the analytical result. Reliable control of power station is the key to stable operation of shipboard power grid. The research between cylinder efficiency and generator power adjustment can provide reference for further operation design and coordinated control.
