Abstract
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.
