A 660MW supercritical unit bypass control method after a load rejection is provided. Steam channels after the load rejection are switched without an interference, and ache steam pressure is controllable. The 660MW supercritical unit bypass control method includes Pipeline, Pipeline, Pipeline, and Pipeline; a bottom of Pipeline, a bottom of the Pipeline, and a head of the Pipelineare connected by a temperature and pressure reducer; a bottom of the Pipelineis connected to a head of Pipeline; a branch pipe is arranged between the Pipelineand the Pipeline, and a steam turbine is arranged in the branch pipe. A high-pressure bypass control system automatically adapts to the load rejection or FCB under any loading situation, avoids drastic changes of unit parameters from loading fluctuations, meets requirements of the load rejection and the FCB.

660MW supercritical unit bypass control system and control method thereof

The present disclosure relates to a feedforward structure for controlling water level, in particular to a feedforward structure for controlling a steam drum water level in a steam turbine FCB test and a control method therefor. The feedforward structure includes a steam drum provided with a steam drum water level measurement sensor therein, a feed water pipe provided with a feed water flow measurement sensor therein, and a steam inlet pipe provided with a steam flow measurement sensor therein. A steam drum water level measurement value I in the steam drum water level measurement sensor is compared with a set value of the steam drum water level.
