The unit coordination adjusting mode of the heat supply unit is to treat the heat supply unit as a whole, and the unit coordination adjusting mode is to adjust the whole electric power of the whole process from the boiler to the intermediate pressure cylinder, the condenser, the high-pressure heater and the low-pressure heater. Along with the continuous increase of the heat supply unit, the response speed of the heat supply unit to AGC commands is gradually reduced, and the electric power of the heat supply unit cannot meet the regulation performance of the heat supply unit by adopting a unit coordination control mode.
In order to solve the technical problem, an embodiment of the application provides a method and a device for adjusting power of a heat supply unit and electronic equipment. The following describes a method, an apparatus, and an electronic device for adjusting power of a heating unit according to an embodiment of the present application with reference to the accompanying drawings.
Illustratively, as shown in fig. 1, an embodiment of the present application provides a heating unit power adjustment method, and an execution subject of the method may be an AGC control terminal.
The heat supply unit comprises but is not limited to a medium pressure cylinder, a low pressure cylinder, a heating network heater, a low pressure cylinder steam inlet adjusting door and the like, wherein the medium pressure cylinder is used for supplying steam to the low pressure cylinder and the heating network heater, the low pressure cylinder steam inlet adjusting door is used for adjusting the air inflow of the low pressure cylinder, and the heating network heater is used for heating the circulating water of the urban heating network to supply heat to the outside. The method for adjusting the power of the heat supply unit specifically comprises the following steps S101-S102:
in S101, a first intake air amount into the low pressure cylinder is adjusted in response to an AGC command instructing to adjust electric power of the heating unit.
Specifically, the AGC command is sent by the AGC system to the heating unit and is used to instruct the heating unit to adjust the electric power of the heating unit, specifically to adjust the electric power of the heating unit to the target power within a predetermined time. The preset time and the target power can take any value according to actual conditions, for example, the electric power of the heating unit is adjusted to 700KW within 30 minutes. When the electric power of the heat supply unit is adjusted, if the current electric power of the heat supply unit is lower than the target power, the air inflow entering the low-pressure cylinder is increased, and if the current electric power of the heat supply unit is higher than the target power, the air inflow entering the low-pressure cylinder is decreased. And if the current electric power of the heating unit is equal to the target power, keeping the air inflow entering the low-pressure cylinder as the current air inflow.
In one possible implementation, adjusting the first intake air amount into the low pressure cylinder includes:
and adjusting the first air inflow entering the low-pressure cylinder by adjusting the opening degree of the air inlet adjusting door of the low-pressure cylinder.
Specifically, in adjusting the electric power of the heat supply unit, if the current electric power of the heat supply unit is lower than the target power, the opening degree of the intake adjustment door of the low pressure cylinder is increased to increase the amount of intake air into the low pressure cylinder, and if the current electric power of the heat supply unit is higher than the target power, the opening degree of the intake adjustment door of the low pressure cylinder is decreased to decrease the amount of intake air into the low pressure cylinder. And if the current electric power of the heat supply unit is equal to the target power, keeping the opening degree of the air inlet adjusting valve of the low-pressure cylinder as the current opening degree so as to keep the air inlet amount entering the low-pressure cylinder as the current air inlet amount.
In S102, the electric power of the heating unit is adjusted according to the work power of the gas with the first air inflow in the low-pressure cylinder.
Specifically, the intermediate pressure cylinder enters air into the low pressure cylinder, the gas (steam) entering the low pressure cylinder does work to generate electric power, and the working power of the low pressure cylinder can be adjusted by adjusting the air inflow of the gas in the low pressure cylinder, so that the low pressure cylinder has the capability of independently adjusting the electric power, and the electric power of the heat supply unit can be correspondingly changed along with the capacity.
In the heat supply period of the heat supply unit, the heat storage of the heat supply network heater is strong, and through the technical scheme provided by the embodiment of the application, the low-pressure cylinder has the capability of adjusting electric power in real time by adjusting the air input of the low-pressure cylinder, the AGC instruction can be quickly responded, and the adjusting capability is strong.
According to the technical scheme provided by the embodiment of the application, the acting power of the gas in the low-pressure cylinder can be adjusted by adjusting the air inflow of the gas in the low-pressure cylinder, the electric power of the heat supply unit can be adjusted by adjusting the acting power of the gas in the low-pressure cylinder, the electric power of the low-pressure cylinder can be independently adjusted to participate in the adjustment of the electric power of the heat supply unit, and the adjustment performance of the heat supply unit is met.
Illustratively, as shown in fig. 2, the embodiment of the present application provides a heating unit power adjusting method, and an execution subject of the method may be an AGC control terminal.
The method for adjusting the power of the heat supply unit specifically comprises the following steps S201 to S203:
in S201, a first intake air amount into the low pressure cylinder is adjusted in response to an AGC command of the heat supply unit, the AGC command instructing to adjust electric power of the heat supply unit.
In S202, the electric power of the heating unit is adjusted according to the work power of the gas with the first air inflow in the low-pressure cylinder.
It is to be noted that S201 and S202 have the same or similar implementation manners as those of S101 to S102 in the above embodiments, which may be referred to each other, and the embodiments of the present application are not described herein again.
In S203, the second intake air amount to the heat supply network heater is adjusted, and the superimposed value of the first intake air amount and the second intake air amount coincides with the air supply amount of the intermediate pressure cylinder.
Specifically, the intermediate pressure cylinder supplies air to the low pressure cylinder and the heating network heater, and when the air inflow entering the low pressure cylinder is adjusted, the air supply amount of the intermediate pressure cylinder can be kept unchanged so as to avoid influencing the operation of other parts of the heat supply unit. Under the condition of keeping the air supply quantity of the intermediate pressure cylinder unchanged, the air intake power generation of the low pressure cylinder and the air intake heat supply of the heat supply network heater are in a matching relation, so that the air intake quantity of the low pressure cylinder can be adjusted under the condition that the electric power of the heat supply unit needs to be adjusted, and the working power of the gas in the low pressure cylinder is changed due to the change of the gas quantity entering the low pressure cylinder, and the electric power of the heat supply unit is changed accordingly. Because the air intake amount of the low pressure cylinder is changed and the air supply amount of the intermediate pressure cylinder is constant, the air intake amount of the heating net heater needs to be reversely adjusted, and the sum of the air intake amount of the low pressure cylinder and the air intake amount of the heating net heater is the same as the air supply amount of the intermediate pressure cylinder.
Under the condition that the air input of the low-pressure cylinder and the air input of the heating network heater are matched, the electric power is independently adjusted by adjusting the low-pressure cylinder, the AGC instruction is quickly responded, and the adjusting performance of the heating unit is improved.
According to the technical scheme provided by the embodiment of the application, the acting power of the gas in the low-pressure cylinder can be adjusted by adjusting the air inflow of the gas in the low-pressure cylinder, the electric power of the heat supply unit can be adjusted by adjusting the acting power of the gas in the low-pressure cylinder, the electric power of the low-pressure cylinder can be independently adjusted to participate in the adjustment of the electric power of the heat supply unit, and the adjustment performance of the heat supply unit is met.
Illustratively, as shown in fig. 3, the embodiment of the present application provides a heating unit power adjusting method, and an execution subject of the method may be an AGC control terminal.
The method for adjusting the power of the heating unit specifically comprises the following steps S300 to S302:
in S300, a predetermined proportion of target electric power is allocated to the low-pressure cylinder from the electric power of the regulated heating unit indicated by the AGC command.
Specifically, when the AGC instruction instructs to adjust the electric power of the heating unit to the target power, partial power can be distributed to the low-pressure cylinder only, and the rest power is adjusted by the original coordination control mode of the heating unit. Therefore, the response speed to the AGC instruction is further improved, and the electric power regulation speed of the heat supply unit is improved.
The predetermined ratio may be 30%, that is, 30% of the target power is distributed to the low-pressure cylinder as the target electric power, and 70% of the target power is distributed to the existing unit coordination manner of the heating unit. When adjusting the air input of the low pressure cylinder, the amount of gas entering the low pressure cylinder is adjusted based on the target electric power, and the working power of the gas entering the low pressure cylinder is consistent with the target electric power.
In a possible implementation manner, the low-pressure cylinder adjusting electric power can be limited, and the low-pressure cylinder adjusting electric power and the heat supply network heater air inlet are matched, specifically, the acting power of the gas with the first air inlet quantity in the low-pressure cylinder is between a first threshold value and a second threshold value. Wherein the first threshold may be-10 MW and the second threshold may be 10 MW. The electric power adjusted by the low-pressure cylinder is limited, so that the normal operation of the heat supply unit is prevented from being influenced by the overweight load of the low-pressure cylinder.
In S301, a first intake air amount into the low pressure cylinder is adjusted in response to an AGC command of the heat supply unit, the AGC command instructing to adjust electric power of the heat supply unit.
In S302, the electric power of the heating unit is adjusted according to the work power of the gas with the first air inflow in the low-pressure cylinder.
In another embodiment, the step of adjusting the second intake air amount into the heat net heater, the overlapped value of the first intake air amount and the second intake air amount corresponding to the air supply amount of the intermediate pressure cylinder, may be further performed after S302. The step of adjusting the second air inflow entering the heat supply network heater, wherein the superposition value of the first air inflow and the second air inflow is consistent with the air supply amount of the intermediate pressure cylinder can be mutually referred to with S203, and the embodiment of the application is not repeated herein.
It is to be noted that S301 and S302 have the same or similar implementation manners as those of S101 to S102 in the above embodiments, which may be referred to each other, and the embodiments of the present application are not described herein again.
