Description

Technical Field

[0001] The present invention relates to the technical field of ground source heat pump control, and particularly to a method, device, electronic device and storage medium for controlling the operation of a ground source heat pump unit. Background Art

[0002] The ground source heat pump converts low-grade heat energy into high-grade heat energy by consuming a certain amount of electric energy, and the operating cost of the heat source ground pump is only 50%-60% of that of a common central air conditioner.

[0003] Most of the existing ground source heat pump units adopt fixed-frequency operation and variable-frequency operation. Among them, during fixed-frequency operation, the ground source heat pump unit operates at the maximum power all year round, but it cannot be adjusted according to the user's load, resulting in relatively large power consumption of the unit; during variable-frequency operation, the ground source heat pump unit starts and stops according to the water temperature on the user side. Although it can achieve a certain energy-saving effect, the proportion of the unit's shutdown time to the operation time is still relatively low, and frequent starting and stopping of the unit also causes relatively large losses to the unit. The control methods of ground source heat pump units in the prior art are relatively simple and crude, resulting in relatively large power consumption and high operating costs of the ground source heat pump units.

However, those skilled in the art should clearly understand that the present invention can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details from interfering with the description of the present invention.

[0060] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will be described through specific embodiments in conjunction with the accompanying drawings.

[0061] See Figure 1 The structural schematic diagram of the ground-source heat pump unit provided by the embodiment of the present invention as shown. The ground-source heat pump unit 1 includes a compressor 11, a ground-source side water pump 12, and a user-side water pump 13. Among them, the ground-source side water pump 12 can be a ground-source side circulation water pump, and the user-side water pump 13 can be a user-side circulation water pump.

When the ground-source heat pump unit is in the constant power control mode, it can receive the control instructions manually set by the control personnel; when the ground-source heat pump unit allows remote control and receives a remote instruction, the ground-source heat pump unit can automatically switch to the power flexible adjustment mode. When the ground-source heat pump unit is in the power flexible adjustment mode, it can be adjusted in real time according to the received control instructions; and when the remote control ends or a communication signal fails, the ground-source heat pump unit will automatically switch from the power flexible adjustment mode to the automatic operation mode.

[0066] In this embodiment, obtaining the current operation mode of the ground-source heat pump unit can clarify the current operation mode of the unit, so as to obtain the corresponding control instruction value and update the control instruction value subsequently.

[0067] When the current operating mode is the automatic operation mode, directly obtain the current command value of the ground source heat pump unit; when the current operating mode is the constant power control mode or the power flexible adjustment mode, there is an external new control command to control the ground source heat pump unit. At this time, obtain the control command value of this control command.

[0068] Specifically, the current operating data may include outdoor temperature, supply water temperature, return water temperature, circulating water flow rate, and return water pressure difference of the user-side water pump, supply water temperature, return water temperature, circulating water flow rate, and return water differential pressure of the ground source side water pump, compressor electric power, compressor frequency converter frequency, ground source side water pump electric power, ground source side water pump frequency converter frequency, user-side water pump electric power, and user-side water pump frequency converter frequency, etc.

[0069] Step S202, calculate the power data of the ground source heat pump unit according to the current operating data.

[0070] In this embodiment, calculating the power data of the ground source heat pump unit can determine the operating states of the compressor, ground source side water pump, user side water pump, and the ground source heat pump unit as a whole in the ground source heat pump unit, so as to update the control command value subsequently and achieve better control of the ground source heat pump unit.

[0071] Step S203, update the current control command value of the ground source heat pump unit according to the power data in the current control mode.

[0072] In this embodiment, in different control modes, the obtained control command value is adjusted and updated according to the power data respectively, so that the control command is more in line with the current operating state of the ground source heat pump unit, which can make the change of the ground source heat pump unit more flexible and also reduce the subsequent operating cost.

[0073] Step S204, control the operation of the ground source heat pump unit according to the updated control command value.

[0074] In the embodiment of the present invention, by obtaining the current operating mode, current control command value, and current operating data of the ground source heat pump unit, and calculating the power data of the ground source heat pump unit according to the current operating data, the current state information of the ground source heat pump unit can be accurately obtained; in the current control mode, updating the current control command value of the ground source heat pump unit according to the power data can automatically adjust the subsequent control command value of the ground source heat pump unit according to the existing control command value, so that the control command is more in line with the current operating state of the ground source heat pump unit to reduce the subsequent operating cost; controlling the operation of the ground source heat pump unit according to the updated control command value can enable the ground source heat pump unit to gradually achieve the control command value under the current operating state, so that the ground source heat pump unit can operate stably and achieve the reduction of the operating cost.

[0075] In a possible implementation, after controlling the operation of the ground source heat pump unit according to the updated control instruction value in step S204, the following steps are further included: obtaining the current operation data of the ground source heat pump unit; calculating the current unit electric power and the current actual heat energy output power of the ground source heat pump unit according to the current operation data; detecting whether there is data information corresponding to the current unit electric power in the database; if there is no data information corresponding to the current unit electric power in the database, storing the current unit electric power, the current actual heat energy output power and the current operation data into the database; if there is data information corresponding to the current unit electric power in the database, detecting whether the current actual heat energy output power is greater than the optimal actual heat energy output power corresponding to the current unit electric power in the database; if the current actual heat energy output power is greater than the optimal actual heat energy output power, updating the database according to the current actual heat energy output power and the current operation data.

[0076] In this embodiment, the operation data and power data corresponding to each typical unit electric power are stored in the database, and the optimal operation data of each typical unit electric power stored in the database are updated according to the actual heat energy data power, which can ensure that the optimal operation data corresponding to each typical unit electric power are always stored in the database. When updating the control instruction value of the ground source heat pump unit, the optimal operation data can always be used as the basis to ensure that the ground source heat pump unit operates optimally, thereby reducing the operation cost of the ground source heat pump unit.

[0077] Among them, the typical unit electric power is obtained by dividing the unit electric power according to the operation data within a period of time to obtain multiple groups of operation data, and then determining the typical unit electric power in each group of operation data respectively.

[0078] In a possible implementation, the ground source heat pump unit includes a compressor, a ground source side water pump and a user side water pump; step S202 calculating the power data of the ground source heat pump unit according to the current operation data can be described in detail as: calculating the heat energy output power of the compressor, the heat energy output power of the ground source side water pump and the heat energy output power of the user side water pump according to the current operation data; determining the minimum heat energy output power among the heat energy output power of the compressor, the heat energy output power of the ground source side water pump and the heat energy output power of the user side water pump as the actual heat energy output power of the ground source heat pump unit; calculating the unit electric power of the ground source heat pump unit according to the current operation data.

[0079] Specifically, calculating the heat energy output power of the compressor, the heat energy output power of the ground source side water pump and the heat energy output power of the user side water pump according to the current operation data can be described in detail as: according to , calculating the heat energy output power of the compressor; according to , calculating the heat energy output power of the ground source side water pump; according to , calculating the heat energy output power of the user side water pump.

[0080] According to the current operating data, calculate the unit electric power of the ground-source heat pump unit, which can be described in detail as follows: According to , calculate the unit electric power of the ground-source heat pump unit.

[0081] Among them, represents the heat output power of the compressor, represents the electric power of the compressor, represents at frequency and ambient temperature the energy efficiency ratio of the compressor, represents the heat output power of the ground-source side water pump, represents the circulating water flow rate of the ground-source side water pump, represents the water supply flow rate of the ground-source side water pump, represents the return water flow rate of the ground-source side water pump, represents the circulation coefficient of the water supply and return water, represents the heat output power of the user side water pump, represents the circulating water flow rate of the user side water pump, represents the water supply flow rate of the user side water pump, represents the water supply flow rate of the user side water pump, represents the unit electric power of the ground-source heat pump unit, represents the electric power of the ground-source side water pump, represents the electric power of the user side water pump.

[0082] In this embodiment, according to the current operating data, calculate the heat output power of the compressor, the heat output power of the ground-source side water pump, and the heat output power of the user side water pump, and the heat output powers of the compressor, the ground-source side water pump, and the user side water pump in the ground-source heat pump unit can be determined respectively. By comparing the respective heat output powers, the actual heat output power of the ground-source heat pump unit can be obtained, and the actual operating state of the ground-source heat pump unit can be determined, so as to perform adjustment according to the actual operating state of the ground-source heat pump unit subsequently.

[0083] In a possible implementation manner, when the current control mode is the automatic operation mode, step S203 updates the current control command value of the ground-source heat pump unit according to the power data in the current control mode, which can be described in detail as follows: Input the current operating data into a preset energy consumption load prediction model to predict the user energy consumption load in the target period, and obtain the load prediction value in the target period; Calculate the target value of the heat power control command of the ground-source heat pump unit according to the load prediction value and the actual heat output power; Calculate the first control command value of the compressor, the second control command value of the ground-source side water pump, and the third control command value of the user side water pump according to the target value of the heat power control command; Update the control command value of the ground-source heat pump unit according to the first control command value, the second control command value, and the third control command value.

[0084] In this embodiment, by using a preset energy consumption load prediction model to predict the energy consumption load of users in the target period, the load prediction value of users in the future target period can be obtained, that is, the energy consumption situation of users can be obtained. Thus, according to this load prediction value, the ground source heat pump unit can be controlled to make the heat energy output situation of the ground source heat pump unit more in line with the actual needs of users. Specifically, by using the load prediction value and the actual heat energy output power, the control command value of the ground source heat pump unit is updated, so as to control the ground source heat pump unit to adjust from the current actual heat energy output power to an operating state that conforms to the load prediction value.

[0085] Furthermore, a preset energy consumption load prediction model can be established through a BP neural network. The BP neural network includes an input layer, a hidden layer, and an output layer. The number of neurons in the input layer can be 7, and the input data is a historical data sequence with 7 dimensions, specifically including weather conditions, the predicted temperature of the target period in the weather forecast, the measured outdoor temperature in the current period, the average indoor temperature in the current period, whether it is working hours, and the heat load of users in the current period; the number of neurons in the output layer is 1, that is, the energy consumption load of users in the target period; the number of neurons in the hidden layer can be calculated according to where, n 1 is the number of neurons in the hidden layer, n is the number of neurons in the input layer, m is the number of neurons in the output layer. After calculation, it can be determined that the number of neurons in the hidden layer is 6.

[0086] Set the activation function, the number of iterations, the maximum number of iterations, and the preset deviation; randomly initialize the weight matrix and the bias matrix, and perform normalization processing on the input data to obtain normalized data; input the normalized data into the BP neural network model to obtain the current prediction value; calculate the net input value and the activation value of each layer in the BP neural network; according to , calculate the error term of each layer, and according to , calculate the error between the current prediction value and the corresponding true value; detect whether the current number of iterations reaches the maximum number of iterations and whether the current error is less than the preset deviation; if the current number of iterations does not reach the maximum number of iterations and the current error is not less than the preset deviation, then add 1 to the current number of iterations, and according to , update the current weight matrix, and according to , update the current bias matrix, and jump to the step of "calculating the net input value and the activation value of each layer in the BP neural network" and execute the subsequent steps; if the current number of iterations reaches the maximum number of iterations or the current error is less than the preset deviation, then the training is completed to obtain the preset energy consumption load prediction model.

[0087] Among them, the activation function is the Sigmoid function, the maximum number of iterations can be set to 3000, and the preset deviation can be set to 0.05; represents the error term of each layer of calculation, z represents the input value of each layer, represents the partial derivative, e represents the error between the current predicted value and the corresponding true value, y 2 represents the current predicted value, y 1 represents the true value corresponding to the current predicted value; W represents the weight matrix of the BP neural network model, b represents the bias matrix of the BP neural network model, represents the learning rate of the BP neural network model, which can be set to 0.01, represents the regularization coefficient, which can be set to 0.4, l represents the current number of iterations, T represents the transpose of the vector.

[0088] Preferably, according to the load prediction value and the actual thermal energy output power, calculate the target value of the thermal energy power control command for the ground source heat pump unit. Specifically, according to , calculate the target value of the thermal energy power control command for the ground source heat pump unit; among them, represents the target value of the thermal energy power control command for the ground source heat pump unit, represents the proportional gain for controlling the power of the ground source heat pump unit, represents the integral gain for controlling the power of the ground source heat pump unit, represents the integral time for controlling the ground source heat pump unit, represents the complex frequency variable in the complex frequency domain, represents the load prediction value at the target moment, represents the actual thermal energy output power of the ground source heat pump unit in the current operating state.

[0089] In a possible implementation manner, according to the target value of the thermal energy power control command, calculate the first control command value of the compressor, the second control command value of the ground source side water pump, and the third control command value of the user side water pump. It can be elaborated as follows: According to the target value of the thermal energy power control command, establish a target space; use the particle swarm optimization algorithm to iteratively calculate the target position with the minimum fitness value in the target space to obtain the first control command value of the compressor, the second control command value of the ground source side water pump, and the third control command value of the user side water pump; among them, during the calculation process, update the target position with the unit's electric power as the fitness value until the current number of iterations reaches the maximum number of iterations and then end.

[0090] Among them, the fitness value can be set to , among which,F represents the fitness value, , , k 1 represents the power flow coefficient of the ground source side water pump, k 2 represents the power flow coefficient of the user side water pump.

[0091] Specifically, the range of the target space is , L d is the upper limit of the target space, U d is the lower limit of the target space; set the relevant parameters of the particle swarm optimization algorithm, the relevant parameters include the particle swarm size, convergence accuracy, number of iterations and maximum number of iterations, and randomly generate the initial positions of the particles in the particle swarm within the target space.

[0092] According to the current position of each particle, calculate the fitness value of each particle; if the fitness value of the particle is less than the fitness value corresponding to the optimal position of the particle, then update the optimal position of the particle to the current position of the particle; if the minimum fitness value in the current particle swarm is less than the fitness value corresponding to the current global optimal position, then update the global optimal position of the current particle swarm to the position of the particle corresponding to the minimum fitness value.

[0093] Detect whether the current number of iterations reaches the maximum number of iterations, and whether the difference between the current global optimal position and the previous global optimal position is less than the convergence accuracy; if the current number of iterations does not reach the maximum number of iterations, and the difference between the current global optimal position and the previous global optimal position is not less than the convergence accuracy, then add 1 to the current number of iterations, update the positions of the particles in the current particle swarm, and jump to the step of "According to the current position of each particle, calculate the fitness value of each particle", and execute the subsequent steps; if the current number of iterations reaches the maximum number of iterations, and the difference between the current global optimal position and the previous global optimal position is less than the convergence accuracy, then determine the global optimal position of the current particle swarm as the control command value; since the target space is a three-dimensional space, the values of the three dimensions corresponding to the global optimal position respectively correspond to the first control command value of the compressor, the second control command value of the ground source side water pump, and the third control command value of the user side water pump.

[0094] And, when updating the positions of the particles in the particle swarm, the following constraint conditions are also satisfied:

[0095]

[0096] Among them, k 3 represents the heat energy reserve coefficient of the ground source side water pump, k 4 represents the heat energy reserve coefficient of the compressor, k 5 represents the heat energy reserve coefficient of the user side water pump.

[0097] It is also possible to determine the corresponding target thermal energy output power according to the first control instruction value, the second control instruction value, and the third control instruction value; detect whether the difference between the target thermal energy output power and the target value of the thermal energy power control instruction is greater than a preset thermal energy power threshold; if the difference is greater than the preset thermal energy power threshold, it means that the current first control instruction value, second control instruction value, and third control instruction value cannot enable the ground source heat pump unit to meet the requirements of the target value of the thermal energy power control instruction. Therefore, it is necessary to recalculate the first control instruction value of the compressor, the second control instruction value of the ground source side water pump, and the third control instruction value of the user side water pump according to the target value of the thermal energy power control instruction until the current difference is not greater than the preset thermal energy power threshold; if the current difference is not greater than the preset thermal energy power threshold, it means that the current first control instruction value, second control instruction value, and third control instruction value can enable the ground source heat pump unit to meet the requirements of the target value of the thermal energy power control instruction, thereby meeting the energy consumption load demand of the user during the target period.

[0098] In addition, the ant colony optimization algorithm can also be used to calculate the first control instruction value of the compressor, the second control instruction value of the ground source side water pump, and the third control instruction value of the user side water pump.

[0099] In this embodiment, by optimizing in the target space using the particle swarm optimization algorithm, the optimal control instruction value can be determined, which can ensure the energy-saving operation of the ground source heat pump unit and reduce the operation cost of the ground source heat pump unit while meeting the energy consumption load demand of the user.

[0100] In a possible implementation manner, when the current control mode is the constant power control mode or the power flexible adjustment mode, step S203 can be detailed as follows: obtaining the adjustment parameters of the ground source heat pump unit in the current control mode; adjusting the current control instruction value according to the adjustment parameters to obtain an adjusted control instruction value; calculating the target value of the electric power control instruction of the ground source heat pump unit according to the adjusted control instruction value and the electric power of the unit; determining the electric power of the compressor, the first flow rate of the ground source side water pump, and the second flow rate of the user side water pump from the database according to the target value of the electric power control instruction; and updating the control instruction value of the ground source heat pump unit according to the electric power, the first flow rate, and the second flow rate.

[0101] In this embodiment, when the current control mode is the constant power control mode or the power flexible adjustment mode, the control instructions are usually externally input instructions, such as the control instructions manually set by the control personnel and the control instructions received during remote control. These control instructions may have a large gap from the current operating state of the ground source heat pump unit. If the ground source heat pump unit directly operates according to the above control instructions, it will cause the ground source heat pump unit to operate unstably, affecting the user's use, and also increasing the control cost of the ground source heat pump unit. Therefore, the control instructions are gradually adjusted according to the adjustment parameters, so that the ground source heat pump unit gradually reaches the operating state corresponding to the control instructions, ensuring that the ground source heat pump unit can operate stably and reducing the operating cost of the ground source heat pump unit.

[0102] Furthermore, in order to enable the ground source heat pump unit to achieve optimal adjustment in each step of adjustment, the operating data such as the optimal electric power of the compressor, the first flow rate of the ground source side water pump, and the second flow rate of the user side water pump under the current conditions can be determined from the database. Thus, the control instruction values of the ground source heat pump unit can be updated respectively according to the operating data corresponding to different moments, and then the control of the ground source heat pump unit can be realized.

[0103] In addition, controlling the ground source heat pump unit to operate according to the updated control instruction value actually means calculating the variable frequency control instruction values of the compressor, the ground source side water pump, and the user side water pump according to the updated control instruction value, and then controlling the compressor, the ground source side water pump, and the user side water pump to perform variable frequency operation according to the variable frequency control instruction values; controlling the compressor, the ground source side water pump, and the user side water pump to perform variable frequency operation can be achieved by the compressor frequency converter, the ground source side water pump frequency converter, and the user side water pump frequency converter to realize frequency conversion.

[0104] Among them, calculating the variable frequency control instruction values of the compressor, the ground source side water pump, and the user side water pump according to the updated control instruction value can be described in detail as follows: According to calculate the variable frequency control instruction value of the compressor; according to calculate the variable frequency control instruction value of the ground source side water pump; according to calculate the variable frequency control instruction value of the user side water pump.

[0105] Among them, represents the variable frequency control instruction value of the compressor, represents the proportional gain for controlling the compressor frequency conversion, represents the integral gain for controlling the compressor frequency conversion, represents the integral time for controlling the compressor frequency conversion, represents the control instruction value of the updated compressor electric power, represents the actual compressor electric power in the current operating state, represents the complex frequency variable in the complex frequency domain, Represents the variable frequency control command value of the ground source side water pump, Represents the proportional gain for controlling the variable frequency of the ground source side water pump, Represents the integral gain for controlling the variable frequency of the ground source side water pump, Represents the integral time for controlling the variable frequency of the ground source side water pump, Represents the updated control command value of the circulating water flow of the ground source side water pump, Represents the actual circulating water flow of the ground source side water pump under the current operating state, Represents the variable frequency control command value of the user side water pump, Represents the proportional gain for controlling the variable frequency of the user side water pump, Represents the integral gain for controlling the variable frequency of the user side water pump, Represents the integral time for controlling the variable frequency of the user side water pump, Represents the updated control command value of the circulating water flow of the user side water pump, Represents the actual circulating water flow of the user side water pump under the current operating state.

[0106] In the embodiments of the present invention, by obtaining the current operating mode, current control command value, and current operating data of the ground source heat pump unit, and calculating the power data of the ground source heat pump unit based on the current operating data, the current state information of the ground source heat pump unit can be accurately obtained; in the current control mode, by updating the current control command value of the ground source heat pump unit according to the power data, the subsequent control command value of the ground source heat pump unit can be automatically adjusted based on the existing control command value, making the control command more in line with the current operating state of the ground source heat pump unit to reduce the cost during subsequent operation; in the automatic operation mode, by using a preset energy consumption load prediction model to predict the energy consumption load of the user in the target time period, the load prediction value of the user in the future target time period is obtained, so that the ground source heat pump unit can be controlled according to the load prediction value, making the heat energy output of the ground source heat pump unit more in line with the actual needs of the user; a database is also set up to store the optimal operating data of the typical unit electric power, so that when updating the control command value of the ground source heat pump unit in the constant power control mode or power flexible control mode, it can always be based on the optimal operating data to ensure that the ground source heat pump unit operates optimally, thereby reducing the operating cost of the ground source heat pump unit; and the control command is gradually adjusted according to the adjustment parameters, so that the ground source heat pump unit gradually reaches the operating state corresponding to the control command, ensuring that the ground source heat pump unit can operate smoothly; controlling the operation of the ground source heat pump unit according to the updated control command value can enable the ground source heat pump unit to gradually achieve the control command value under the current operating state, enabling the ground source heat pump unit to operate smoothly and reducing the operating cost.
