Description

Technical Field

[0001] This application relates to the field of nuclear reactor power control, and in particular to a method, apparatus, equipment and storage medium for adjusting the load of a high-temperature gas-cooled reactor. Background Technology

[0002] In related technologies, high-temperature gas-cooled reactors typically operate under a "set load" mode, where the NSSS (Nuclear Steam Supply System) modules of both reactors and one turbine generator unit all operate under a set target load. Under this mode, when the system load changes, the reactor power changes first, and the turbine power follows the reactor power change, which is beneficial for the stable operation of the reactor. However, the unit's load tracking capability is poor, and it cannot participate in grid peak shaving and frequency regulation.

[0003] With changes in energy policy, nuclear power plants also need to participate in grid peak shaving or frequency regulation. The operating load control strategy under the "set load" operation mode cannot meet the grid's peak shaving and frequency regulation needs. Summary of the Invention

[0034] Please see Figure 1 , Figure 1 This is a schematic diagram of a high-temperature gas-cooled reactor load regulation method provided in an embodiment of this application. Figure 1 As shown, the method may include, but is not limited to, the following steps.

[0035] Step S101: Obtain the process variables of the high-temperature gas-cooled reactor.

[0036] For example, process variables of the high-temperature gas-cooled reactor can be obtained by pre-setting various sensors at different locations in the reactor.

[0037] Step S102: Obtain control signals based on process variables, and adjust the load of the high-temperature gas-cooled reactor based on the control signals.

[0038] In the embodiments of this application, the control signal includes at least one of the following: control rod position signal, main helium blower speed signal, and feed water pump speed signal.

[0039] For example, based on the process variables obtained above, a control signal including at least one of the control rod position signal, the main helium blower speed signal, and the feedwater pump speed signal is obtained, and the corresponding part of the high-temperature gas-cooled reactor is controlled based on the above control signal to adjust the load of the high-temperature gas-cooled reactor.

[0040] By implementing the embodiments of this application, control signals can be obtained based on the acquired process variables of the high-temperature gas-cooled reactor, and the load of the high-temperature gas-cooled reactor can be adjusted based on the control signals. This allows for automatic control of the reactor power to track the turbine load.

[0041] In one implementation, process variables include the measured hot helium temperature at the hot helium outlet in the high-temperature gas-cooled reactor and the measured nuclear power, with the control signal being the control rod position signal. For an example, please refer to [link to example]. Figure 2 , Figure 2 This is a schematic diagram of another high-temperature gas-cooled reactor load regulation method provided in the embodiments of this application. Figure 2 As shown, the method may include, but is not limited to, the following steps.

[0042] Step S201: Obtain the measured values ​​of hot helium temperature and nuclear power at the hot helium outlet in the high-temperature gas-cooled reactor.

[0043] For example, the hot helium temperature is measured by a temperature sensor pre-installed at the hot helium outlet of the high-temperature gas-cooled reactor, and the nuclear power of the high-temperature gas-cooled reactor is also measured.

[0044] Step S202: Obtain the nuclear power setting value based on the measured value of the hot helium temperature and the set value of the hot helium temperature.

[0045] For example, the hot helium temperature deviation value is obtained by subtracting the hot helium temperature measurement value from the preset hot helium temperature setting value, and the nuclear power setting value that can reduce the hot helium temperature deviation value is obtained based on the hot helium temperature deviation value.

[0046] In some embodiments of this application, the nuclear power setting value can be calculated based on the above-mentioned hot helium temperature deviation value using a preset automatic control algorithm.

[0047] Step S203: Based on the nuclear power measurement value and the nuclear power set value, obtain the control rod position signal.

[0048] For example, the nuclear power deviation value is obtained by subtracting the nuclear power measurement value from the nuclear power setpoint. Based on the nuclear power deviation value and the deviation change signal representing the type of nuclear power deviation value (e.g., positive or negative), a target control rod position signal that can reduce the nuclear power deviation value is obtained. Based on the target control rod position signal and the current control rod position, a control rod position signal that adjusts the control rod position by raising or lowering is obtained.

[0049] In one implementation of this application, the control rod position signal can be obtained by calculating based on the deviation value and deviation change signal between the two using a preset power adjustment algorithm.

[0050] Step S204: Adjust the load of the high-temperature gas-cooled reactor based on the control rod position signal.

[0051] For example, based on the control rod position signal, the control rod can be raised or lowered to adjust the nuclear power, thereby regulating the load of the high-temperature gas-cooled reactor.

[0052] By implementing the embodiments of this application, control rod position signals can be obtained based on the measured hot helium temperature and nuclear power values ​​at the hot helium outlet in the high-temperature gas-cooled reactor, and the load of the high-temperature gas-cooled reactor can be adjusted based on the control rod position signals. This satisfies the requirement for automatic control of reactor power to track turbine load.

[0053] In one implementation, process variables include the measured helium flow rate of the primary coolant system in the high-temperature gas-cooled reactor and the measured steam temperature at the steam generator outlet, with the control signal being the main helium blower speed signal. For an example, please refer to [link to example]. Figure 3 , Figure 3 This is a schematic diagram of another method for adjusting the load of a high-temperature gas-cooled reactor provided in the embodiments of this application. Figure 3 As shown, the method may include, but is not limited to, the following steps.

[0054] Step S301: Obtain the helium flow rate measurement value of the primary coolant system in the high-temperature gas-cooled reactor and the steam temperature measurement value of the steam generator outlet.

[0055] For example, the flow rate of helium in the primary coolant system of the high-temperature gas-cooled reactor is measured by a pre-set flow sensor, and the steam temperature at the steam generator outlet of the high-temperature gas-cooled reactor is measured by a pre-set temperature sensor.

[0056] Step S302: Based on the measured steam temperature and the set steam temperature, obtain the target value of helium flow rate.

[0057] For example, the temperature deviation value is obtained by subtracting the steam temperature measurement value from the steam temperature set value. Based on this temperature deviation value, the target value of helium flow rate that can reduce the temperature deviation value is obtained.

[0058] In one implementation of this application, the target value of helium flow rate can be obtained based on the above-mentioned temperature deviation value through a preset temperature control algorithm.

[0059] Step S303: Based on the target value of helium flow rate and the measured value of helium flow rate, obtain the main helium blower speed signal.

[0060] For example, the flow rate deviation is obtained by subtracting the target value of helium flow rate from the measured value of helium flow rate, thereby obtaining the target speed of the main helium blower that can reduce the flow rate deviation value, and generating the main helium blower speed signal based on the target speed.

[0061] In some embodiments of this application, the main helium blower speed signal can be obtained based on the above-mentioned flow deviation value through a preset helium flow control algorithm.

[0062] Step S304: Adjust the load of the high-temperature gas-cooled reactor based on the main helium blower speed signal.

[0063] For example, the load on the high-temperature gas-cooled reactor can be adjusted based on the main helium blower speed signal.

[0064] By implementing the embodiments of this application, the main helium blower speed signal can be obtained based on the acquired helium flow rate measurement value and the steam temperature measurement value at the steam generator outlet, and the load of the high-temperature gas-cooled reactor can be adjusted based on the main helium blower speed signal. This satisfies the requirement of automatic control of reactor power to track turbine load.

[0065] In one implementation, the process variables include the turbine impulse stage pressure measurements of the high-temperature gas-cooled reactor, and the control signal is the feedwater pump speed signal. For an example, please refer to [link to example]. Figure 4 , Figure 4 This is a schematic diagram of another method for adjusting the load of a high-temperature gas-cooled reactor provided in the embodiments of this application. Figure 4 As shown, the method may include, but is not limited to, the following steps.

[0066] Step S401: Obtain the pressure measurement value of the turbine impulse stage of the high-temperature gas-cooled reactor.

[0067] For example, the pressure measurement value of the turbine impulse stage of the high-temperature gas-cooled reactor can be obtained by using a pre-set pressure sensor.

[0068] Step S402: Obtain the feedforward signal of the water pump speed.

[0069] For example, the feedwater pump speed feedforward signal is obtained from a preset reactor power-feedwater pump speed characteristic table.

[0070] Step S403: Based on the turbine impulse stage pressure measurement value and the turbine impulse stage pressure set value, correct the feedwater pump speed feedforward signal to obtain the feedwater pump speed signal.

[0071] For example, the turbine impulse stage pressure deviation value is obtained by subtracting the turbine impulse stage pressure measurement value from the preset turbine impulse stage pressure setting value. Based on the impulse stage pressure deviation value, the feedwater pump speed feedforward signal is corrected to obtain a feedwater pump speed signal that can reduce the impulse stage pressure deviation value.

[0072] In one implementation of an embodiment of this application, the feedwater pump speed signal can be obtained by correcting the feedwater pump speed feedforward signal through a pre-set feedwater flow control algorithm based on the impulse stage pressure deviation value.

[0073] Step S404: Adjust the load of the high-temperature gas-cooled reactor based on the feedwater pump speed signal.

[0074] For example, the feedwater pump speed is adjusted based on the feedwater pump speed signal, thereby changing the steam generator feedwater flow rate to maintain the turbine impulse stage pressure at the set value, thus regulating the load on the high-temperature gas-cooled reactor.

[0075] By implementing the embodiments of this application, a water pump speed signal can be obtained based on the acquired turbine impulse stage pressure measurement value of the high-temperature gas-cooled reactor, and the load of the high-temperature gas-cooled reactor can be adjusted based on the water pump speed signal. This satisfies the requirement of automatic control of reactor power to track turbine load.

[0076] Please see Figure 5 , Figure 5 This is a schematic diagram of the high-temperature gas-cooled reactor load adjustment method provided in the embodiments of this application. Figure 5 As shown, the high-temperature gas-cooled reactor on-site load regulation method provided in this application can obtain nuclear power measurement values ​​through a nuclear power measurement module and hot helium outlet temperature measurement values ​​through a helium outlet temperature measurement module. Then, the reactor control loop controls the control rod positions in the nuclear reactor based on these nuclear power and hot helium temperature measurements. Simultaneously, it can obtain helium flow rate measurements from the primary coolant system through a nitrogen flow rate measurement module and steam temperature measurements through a steam generator outlet temperature measurement module. Then, the steam generator temperature control loop controls the main helium blower speed based on these helium flow rate and steam temperature measurements. Furthermore, it can obtain turbine impulse stage pressure measurements through a turbine impulse stage pressure measurement module, and then the turbine impulse stage pressure control loop controls the feedwater pump speed based on these turbine impulse stage pressure measurements. Therefore, the high-temperature gas-cooled reactor on-site load can be regulated using the above methods.

[0077] Please see Figure 6 , Figure 6 This is a schematic diagram of a reactor control method provided in an embodiment of this application. Figure 6 As shown, the reactor control loop can acquire nuclear power measurements and hot helium temperature measurements. Based on the difference between the hot helium temperature setpoint and the measured hot helium temperature, and combined with a hot helium temperature control algorithm, it obtains the nuclear power setpoint. Then, based on the deviation and deviation change signal between the nuclear power setpoint and the measured nuclear power, and combined with a power regulation algorithm, it adjusts the position of the control rods to raise or lower them, thereby regulating the nuclear power.

[0078] Please see Figure 7 , Figure 7 This is a schematic diagram of a steam generator outlet temperature control method provided in an embodiment of this application. Figure 7 As shown, the steam generator outlet temperature control loop can acquire the measured value of the steam temperature at the steam generator outlet. Based on the measured value and the steam temperature setpoint, the helium flow rate setpoint is obtained through the evaporator outlet temperature control algorithm. Then, based on the helium flow rate setpoint and the acquired helium flow rate measured value, the speed of the main helium blower is controlled through the helium flow rate control algorithm, thereby achieving the adjustment of the evaporator outlet temperature.

[0079] Please see Figure 8 , Figure 8 This is a schematic diagram of a turbine impulse stage pressure control method provided in an embodiment of this application. Figure 8 As shown, the turbine impulse stage pressure control loop can acquire the turbine impulse stage pressure measurement value, and based on the turbine impulse stage pressure measurement value and the turbine impulse stage pressure set value, correct the speed feedforward signal through the feedwater flow control algorithm to control the feedwater pump speed, thereby changing the steam generator feedwater flow to maintain the turbine impulse stage pressure at the set value.
