Turbine bypass control apparatus and turbine bypass control method |
摘要 |
A turbine bypass control method includes: a high-pressure side pressure controller configured to output a first operation amount signal corresponding to a valve opening; a low-pressure side pressure controller configured to output a second operation amount signal corresponding to a valve opening; a high value selector configured to output as a high value operation amount signal, one of the first operation amount signal and the second operation amount signal which indicates a larger opening; a first signal switching unit configured to receive the high value operation amount signal and the second operation amount signal and output a first bypass valve operation amount signal; a second signal switching unit configured to receive the high value operation amount signal and the first operation amount signal and output a second bypass valve operation amount signal; and a rapid opening controller. Before start of trip of a turbine, the turbine is driven by steam which flows from the high-pressure side header to the low-pressure side header through the turbine. |
