Embodiment Construction
[0034] The present invention will be described below with reference to the accompanying drawings.
[0035]A kind of intermittent control method of the present invention to quickly eliminate the static deviation of the main steam pressure of the thermal power unit is realized by the following technical scheme:
[0036] Real-time monitoring of the static deviation of the main steam pressure of the thermal power unit, when the static deviation of the steam pressure exceeds the specified value, using the step output characteristics of the differential control module, on the basis of the original boiler fuel quantity command, through intermittent rapid superposition and steam pressure static The fuel volume command offset corresponding to the deviation can adjust the fuel volume of the boiler in time, so that the static deviation of the main steam pressure of the unit can be quickly eliminated.
[0037] The fuel adjustment of the boiler is divided into upper and lower layers, namel...
