[0045] The 2X350MW supercritical circulating fluidized bed unit of a power plant in Shanxi adopts the main steam flow rate as the main input factor to ensure the rapid response of the main steam pressure. Newly added mid-point temperature deviation feed water correction and mid-point temperature boiler main control deviation, when pressure fluctuations occur , relying on the feedback adjustment of the main steam flow, when the main steam temperature deviates from the target value, relying on the intermediate temperature deviation to act on the water supply and coal flow together, the safety of the unit can be more reliably guaranteed.
[0046] Such as Figure 7As shown, the parameter record curve after adopting the water supply control strategy, in which the curve 1 is the target load command, the curve 2 is the actual power of the generator, the curve 3 is the set value of the main steam pressure, and the curve 4 is the pressure of the turbine inlet main pipe. Curve 5 is the ...
