Fig. 3 is a flowchart of an information monitoring method for a nuclear power generating unit according to an embodiment of the present disclosure, and referring to fig. 3, the method includes the following steps.

Step 301: the monitoring equipment acquires the current state parameters of the nuclear power generating unit.

The operation state of the nuclear power unit can be reflected by the state parameters of the nuclear power unit, so that the monitoring equipment needs to acquire the current state parameters of the nuclear power unit.

As an example, various sensing devices can be arranged in the nuclear power generating unit, and the sensing devices can acquire state parameters of the nuclear power generating unit and send the state parameters to the monitoring device after acquiring the state parameters of the nuclear power generating unit, so that the monitoring device acquires the state parameters of the nuclear power generating unit.

It should be noted that the state parameters of the nuclear power generating unit can include some data related to a nuclear island, a steam turbine, a heat supply head station, and the like, such as a stack load, a heat load amount, an electric load amount, an external steam supply pressure, an external steam supply temperature, a reactor average temperature, a reactor reference average temperature, a steam generator outlet pressure, a steam generator outlet temperature, a main steam flow rate, a main steam temperature, a turbine first stage front pressure, a water supply flow rate, a water supply temperature, a heater drainage temperature, a heat supply network water supply flow rate, a heat supply network water supply temperature, a heat supply network return water flow rate, a heat supply network return water pressure, and the like.

In some embodiments, since the state parameters include thermal load, the more thermal load indicates more electric quantity provided by the nuclear power plant, and therefore, after the monitoring device obtains the current state parameters of the nuclear power plant, the power generation power of the nuclear power plant can be adjusted according to the thermal load.

As an example, when the state parameter includes a thermal load amount, the monitoring device can acquire a steam pressure corresponding to the thermal load amount; obtaining the current stack power corresponding to the steam pressure from the corresponding relation between the pressure and the stack power; and adjusting the generating power of the nuclear power unit according to the current stack power and the reference stack power.

It should be noted that the state parameter can include the steam pressure corresponding to the thermal load amount, and therefore, when the state parameter includes the thermal load amount, the monitoring device can obtain the steam pressure corresponding to the thermal load amount from the state parameter; or, the monitoring device may store a correspondence between the thermal load amount and the steam pressure in advance, and when the state parameter includes the thermal load amount, may obtain the corresponding steam pressure from the correspondence between the thermal load amount and the steam pressure.

It should be noted that the reference stack power can be set in advance according to the requirement, for example, the reference stack power can be 100%.

As an example, the monitoring device can obtain the current stack power corresponding to the steam pressure from the corresponding relationship between the pressure and the stack power, and of course, the current stack power can be detected by the sensing device.

As an example, the operation of the monitoring device for adjusting the power generation of the nuclear power plant based on the current stack power and the reference stack power at least comprises: subtracting the current stack power from the reference stack power, and determining the obtained stack power difference as the added value of the generated power; and controlling the generated power of the nuclear power unit to increase a generated power added value from the current generated power so as to adjust the generated power of the nuclear power unit, wherein the generated power added value is the generated power which can be increased by the nuclear power unit at present.

As an example, after determining the generated power added value, the monitoring device can also send a generated power adjustment request to the grid dispatching device, where the generated power adjustment request carries the generated power added value; when the power grid dispatching equipment receives the generated power adjustment, feedback information can be returned to the monitoring equipment according to the generated power increase value, wherein the feedback information comprises information whether the generated power is allowed to be increased or not and/or reference generated power, and the reference generated power is the generated power allowed to be increased by the nuclear power unit; and after receiving the feedback information, the monitoring equipment adjusts the generating power of the nuclear power unit according to the reference generating power.

As an example, the monitoring device can also obtain the upper limit value of the generated power after determining the increment of the generated power; determining the sum of the current generating power and the added value of the generating power of the nuclear power unit, and controlling the generating power of the nuclear power unit to rise to the upper limit value of the generating power when the sum of the current generating power and the added value of the generating power of the nuclear power unit is greater than or equal to the upper limit value of the generating power; when the sum of the current generating power and the added value of the generating power of the nuclear power unit is smaller than the upper limit value of the generating power, the generating power of the nuclear power unit is controlled to increase the added value of the generating power from the current generating power so as to adjust the generating power of the nuclear power unit.

The method has the advantages that the current pile power can be determined through the thermal load, and the generating power of the nuclear power unit is adjusted according to the pile power, so that the generating efficiency of the nuclear power unit is improved, the pile power is utilized to the maximum extent, and the waste of resources is avoided.

In some embodiments, after obtaining the current state parameter of the nuclear power unit, the monitoring device can not only adjust the power generation power of the nuclear power unit, but also determine the current operation state of the nuclear power unit through the following

steps

303 and 304, so as to monitor the nuclear power unit.

Step 302: and the monitoring equipment acquires the state constraint condition of the nuclear power unit according to the state parameters.

As the nuclear power unit is usually in a safe state, and the state parameters of the nuclear power unit are usually limited within a certain range. When equipment is abnormal, the state parameters of the nuclear power unit are changed, the state constraint conditions corresponding to different state parameters are different, and when the state parameters of the nuclear power unit are changed, the constraint conditions of the state parameters may also be changed, so that the monitoring equipment can acquire the state constraint conditions of the nuclear power unit according to the state parameters.

In some embodiments, the obtaining, by the monitoring device, the condition of the state constraint condition of the nuclear power plant according to the state parameter at least includes the following operations: when the state parameters comprise the current thermal load and the current electric load of the nuclear power unit, determining an electric load interval of the nuclear power unit through a thermal balance characteristic diagram according to the thermal load; and determining a heat load interval provided by the nuclear power unit through a thermodynamic balance characteristic diagram according to the electric load quantity.

Because the thermal load capacity and the electrical load capacity of the nuclear power unit have an incidence relation, when the state parameters comprise the current thermal load capacity and the current electrical load capacity of the nuclear power unit, the electrical load interval of the nuclear power unit is determined through a thermal balance characteristic diagram according to the thermal load capacity; and determining a heat load interval provided by the nuclear power unit through a thermodynamic balance characteristic diagram according to the electric load quantity.

In some embodiments, as can be seen from the foregoing, the status parameters can include various parameters, and different parameters correspond to different status constraint conditions, so that the monitoring device can obtain the status constraint conditions from a stored database according to the status parameters while determining the electrical load interval of the nuclear power unit through the thermal balance characteristic diagram according to the thermal load amount and determining the thermal load interval provided by the nuclear power unit through the thermal balance characteristic diagram according to the electrical load amount, for example, can obtain the current electricity price, the heat price, the initial heat supply and electrical load threshold, the steam extraction and heat supply flow threshold, the change rate threshold of the turbine lifting load, the change rate threshold of the reactor lifting load, the heat load change rate threshold, the recommended change range of the stack power, and the like.

It should be noted that the monitoring device can acquire the state constraint condition of the nuclear power unit according to the state parameter when the nuclear power unit is in the steam extraction and heat supply working condition.

And 303, determining the running state of the nuclear power unit by the monitoring equipment according to the state parameters and the state constraint conditions so as to realize information monitoring of the nuclear power unit.

As can be seen from the above, the state constraint conditions corresponding to different state parameters are different, and therefore, the operation of the monitoring device for determining the operating state of the nuclear power generating unit according to the state parameters and the state constraint conditions can include multiple situations.

As an example, when the state constraint condition at least includes a change rate condition and a parameter limit condition, the operation of the monitoring device determining the operating state of the nuclear power plant according to the state parameter and the state constraint condition at least includes: when a parameter with a change rate which does not accord with a corresponding change rate condition exists in the state parameters, or a parameter which does not accord with a corresponding parameter limiting condition exists in the state parameters, determining that the running state of the nuclear power unit is a dangerous state; and when the change rate of each parameter in the state parameters meets the corresponding change rate condition and each parameter in the state parameters meets the corresponding parameter limiting condition, determining that the running state of the nuclear power unit is a safe state.

It should be noted that the state parameters can include stack power, thermal load, electrical load, and the like, and the change rate condition can include a threshold of change rate of turbine lift load, a threshold of change rate of reactor lift load, a threshold of change rate of thermal load, and the like; the parameter limits can include a stack power recommended range of change, an initial heating power load threshold, an extraction heating flow threshold, and so forth.

As an example, when the state parameters at least include a current thermal load amount and an electrical load amount of the nuclear power plant, and the state constraint condition at least includes an electrical load interval and a thermal load interval of the nuclear power plant and thermal load change rate threshold data of the nuclear power plant, the operation of the monitoring device determining the operating state of the nuclear power plant according to the state parameters and the state constraint condition at least includes: determining the heat load of the nuclear power unit obtained last time; determining the thermal load change rate of the nuclear power unit according to the thermal load obtained last time and the current thermal load; when the electric load quantity exceeds the electric load interval, or when the current heat load quantity exceeds the heat load interval, or when the heat load change rate is greater than the heat load change rate threshold value, determining that the running state of the nuclear power unit is a safe state; and when the current electric load quantity does not exceed the electric load interval, the current heat load quantity does not exceed the heat load interval, and the heat load change rate is less than or equal to the heat load change rate threshold, determining that the running state of the nuclear power unit is a dangerous state.

As an example, when the monitoring device determines the operating state of the nuclear power plant according to the state parameters and the state constraints, the operation of determining the operating state of the nuclear power plant at least comprises: when the state parameters comprise the generated energy limiting information of the nuclear power unit, determining the operation duration of the nuclear power unit in the corresponding electric power lower limit interval, wherein the generated energy limiting information is used for describing the current working condition of limiting the generated energy of the nuclear power unit; when the operation duration is greater than a duration threshold, determining that the operation state of the nuclear power unit is a dangerous state; and when the operation time length is less than or equal to the time length threshold value, determining that the operation state of the nuclear power unit is a safe state.

The power grid dispatching equipment does not allow the nuclear power unit to provide a large amount of electric quantity at some time, and the electric quantity of the nuclear power unit can be limited at the moment, so that the nuclear power unit is in the working condition of limiting the electric quantity, or when the nuclear power unit is in a debugging stage, the nuclear power unit is not allowed to provide a large amount of electric quantity at the same time, and at the moment, the nuclear power unit is also in the working condition of limiting the electric quantity. Therefore, the state parameter may include power generation amount limit information of the nuclear power generating unit.

When the nuclear power unit is in a limited power generation working condition, the nuclear power unit usually operates in an electric power lower limit area, and the nuclear power unit is usually not allowed to operate for too long under the working condition. Therefore, when the operation duration is greater than the duration threshold, the monitoring equipment can determine that the operation state of the nuclear power unit is a dangerous state; and when the operation time length is less than or equal to the time length threshold value, determining that the operation state of the nuclear power unit is a safe state.

It should be noted that the time period threshold can be set in advance according to requirements, for example, the time period threshold can be 30 minutes, 1 hour, and the like.

In some embodiments, before determining the operating state of the nuclear power generating unit according to the state parameters and the state constraint conditions, the monitoring device can also obtain construction information of the nuclear power generating unit, wherein the construction information is used for describing the connection relationship of each structure in the nuclear power generating unit; establishing a system state diagram of the nuclear power unit according to the construction information of the nuclear power unit, wherein the system state diagram is used for describing the construction of the nuclear power unit; and displaying the state parameters in a system state diagram of the nuclear power unit.

In order to enable a worker to know the current operation state of the nuclear power generating unit and the state parameters of each device in time, the monitoring device can establish a system state diagram and display the state parameters of the nuclear power generating unit in the system state diagram.

Step 304: and when the running state of the nuclear power unit is a dangerous state, prompting is carried out through prompt information.

Because when the running state of the nuclear power unit is a dangerous state, the equipment may be damaged, and other potential safety hazards may be brought, in order to timely handle the danger that may occur, when the running state of the nuclear power unit is a dangerous state, the monitoring equipment prompts through prompt information.

It should be noted that the prompt information includes at least one of text prompt information, picture prompt information, video prompt information, and sound prompt information.

Therefore, when the running state of the nuclear power unit is a dangerous state, the monitoring equipment can display the state parameters which cause the abnormality through highlight or target colors. The abnormality-generating state parameter is a parameter that does not satisfy a state constraint condition. The target color can be red, orange, etc.

In the embodiment of the application, the monitoring equipment can monitor the running state of the nuclear power unit according to the acquired state information and state constraint conditions of the nuclear power unit, for example, whether the running state of the nuclear power unit is a safe state or not is monitored, and when the running state is a dangerous state, the running state can be timely reminded, so that the condition that the productivity and the working efficiency of the nuclear power unit are influenced due to abnormal running of the equipment of the nuclear power unit is improved. Meanwhile, the monitoring equipment can also adjust the power generation power of the nuclear power unit according to the state parameters, so that the utilization rate of the stack power is ensured, and the power generation and heat supply efficiency of the nuclear power unit is improved.
