The invention provides a
power control method of a heat storage peak shaving
system under heat storage and heat release working conditions. The heat storage peak shaving
system is included. In a heatstorage mode, after
condensed water (cold water) sent out by a
condensed water pump passes through a heater, the cold water is changed into hot water, one path of hot water enters a
deaerator, the other path of hot water enters a
water storage tank, and the equal amount of cold water is discharged to a condenser from the
water storage tank. Due to the fact that the total amount of hot water entering the
deaerator is relatively fixed, the flow entering the
water storage tank is increased, the flow passing through the heater is also increased, the generating power of a unit is reduced, and viceversa. In a heat release mode, one path of
condensed water sent out by the condensed water pump passes through the heater to enter the
deaerator, the other path of the condensed water sent out by thecondensed water pump enters the
water storage tank, and the equal amount of hot water is pumped to the deaerator from the
water storage tank through a
booster pump. Due to the fact that the total amount of hot water entering the deaerator is relatively fixed, the flow pumped out of the
water storage tank is increased, the flow passing through the heater is reduced, the generating power of the unitis increased, and vice versa. An applicant proposes a heat storage technology by using the water
storage tank, the ramp rate of the unit is increased, a
power grid dispatching instruction is rapidlyresponded, and the
power control method of the heat storage peak shaving
system under heat storage and heat release working conditions is a new mode for increasing the ramp rate of the unit.
