[0025] S102, obtain the production parameters and energy consumption parameters corresponding to the equipment system, wherein the energy consumption parameters include multiple energy types and the energy consumption corresponding to each of the multiple energy types;

[0026] In step S102 of this application, the production parameters and energy consumption parameters corresponding to the equipment system are obtained.

[0027] This involves an equipment system, which is a system for energy conversion. The equipment system includes multiple devices corresponding to energy conversion, such as a power system. These devices work together to realize the production operation of the equipment system.

[0028] This involves a production parameter, which represents the output of the equipment system within a predetermined time (such as one year). For example, taking a power system as an example, the production parameter includes the power generation of the power system within the predetermined time.

[0030] This involves multiple energy types, which are used to distinguish different energy sources. For example, the different energy sources that the equipment system may consume during operation include coal, natural gas, etc.

[0031] This includes energy consumption, which represents the amount of each type of energy consumed by the equipment system during operation.

[0032] By acquiring the production and energy consumption parameters corresponding to the equipment system, we can gain a comprehensive understanding of the energy usage and production status of the equipment system during operation, including the consumption of different energy types and their corresponding production output, providing a data foundation for subsequent analysis.

[0034] In step S104 of this application, the energy demand parameters corresponding to the equipment system are determined based on the production parameters and energy consumption parameters.

[0035] This includes energy demand parameters, which represent the total energy demand of the equipment system during operation.

[0036] Energy demand parameters reflect the actual energy demand of an equipment system under specific operating conditions. In other words, they can clearly define the specific energy requirements of the equipment system for various energy sources and serve as the basic data for assessing the waste heat utilization potential of the equipment system.

[0039] This includes consumption characteristic parameters, which are parameters used to describe the consumption characteristics of each type of energy in the equipment system during operation, such as energy percentage.

[0040] By determining the energy consumption corresponding to each of the multiple energy types, the consumption characteristic parameters corresponding to each of the multiple energy types can be determined, which can accurately characterize the consumption characteristics of different energy types in the equipment system, such as the proportion of each energy type, thereby helping to quantitatively assess the waste heat utilization potential of the equipment system.

[0041] S108, determine the waste heat loss index corresponding to multiple energy types respectively, wherein the waste heat loss index represents the degree to which the energy under the corresponding energy type is lost in the form of waste heat during the consumption of the equipment system;

[0042] In step S108 provided in this application, waste heat loss indices corresponding to multiple energy types are determined.

[0043] This includes the waste heat loss index, which measures the degree of energy lost in the form of waste heat during the process of consuming a certain type of energy in an equipment system.

[0044] The waste heat loss index can quantify the degree of energy loss in the form of waste heat during the operation of equipment systems of different energy types. By clarifying the degree of waste heat loss of each energy type, the relationship between waste heat loss and energy consumption of different energy types during the operation of equipment systems can be more accurately quantified, which helps to accurately determine the waste heat utilization parameters of equipment systems in the future.

[0045] S110, based on energy demand parameters, consumption characteristic parameters corresponding to multiple energy types, and waste heat loss index, determine the waste heat utilization parameters corresponding to the equipment system. The waste heat utilization parameters are used to represent the waste heat utilization performance of the equipment system, and include the amount of waste heat utilized.

[0046] In step S110 of this application, waste heat utilization parameters corresponding to the equipment system are determined based on energy demand parameters, consumption characteristic parameters corresponding to multiple energy types, and waste heat loss index.

[0047] This involves waste heat utilization parameters, which are indicators used to quantify the waste heat utilization performance of the equipment system. These parameters mainly include the amount of waste heat utilized and the effective amount of waste heat utilized. The amount of waste heat utilized reflects the total amount of waste heat energy recovered and utilized by the equipment system, while the effective amount of waste heat utilized reflects the total amount of waste heat energy that the equipment system can effectively recover and utilize, taking into account the operating conditions of the equipment system (such as ambient temperature).

[0048] Energy demand parameters define the total energy demand of the equipment system under specific operating conditions. Consumption characteristic parameters reflect the specific consumption patterns of different energy types in the equipment system. Waste heat loss index quantifies the degree of energy loss in the form of waste heat during the consumption process of different energy types.

[0049] Through the above steps S102-S110, the production parameters and energy consumption parameters corresponding to the equipment system are obtained. The energy consumption parameters include multiple energy types and their respective energy consumption amounts. Based on the production parameters and energy consumption parameters, the energy demand parameters corresponding to the equipment system are determined. Based on the energy consumption amounts corresponding to the multiple energy types, the consumption characteristic parameters corresponding to the multiple energy types are determined. The waste heat loss index corresponding to the multiple energy types is determined, where the waste heat loss index represents the degree to which energy of the corresponding energy type is lost as waste heat during the consumption process by the equipment system. Based on the energy demand parameters, the consumption characteristic parameters corresponding to the multiple energy types, and the waste heat loss index, the waste heat utilization parameters corresponding to the equipment system are determined. These waste heat utilization parameters represent the waste heat utilization performance of the equipment system and include the amount of waste heat utilized. By determining the energy demand parameters of the equipment system based on its output and energy consumption parameters, the total demand of the equipment system for various energy sources can be quantified. Furthermore, by combining the consumption characteristic parameters of different energy types in the equipment system with the waste heat loss index of different energy types, the energy consumption characteristics of the equipment system can be comprehensively evaluated. This allows for the comprehensive and accurate quantification of the waste heat utilization parameters of the equipment system, thereby solving the technical problem of inaccurate determination of waste heat utilization parameters in related technologies.

[0054] This involves the target utilization method, which is the waste heat utilization method that the equipment system is most likely to use (i.e., the one that best matches the equipment system) selected from multiple waste heat utilization methods based on a comprehensive evaluation of utilization capacity parameters.

[0055] By evaluating the utilization capacity parameters of various waste heat utilization methods, the impact of each waste heat utilization method on the waste heat utilization potential of the equipment system can be accurately quantified. This allows us to determine the waste heat utilization method most likely to be used by the equipment system. Furthermore, by combining energy demand parameters, consumption characteristic parameters, and waste heat loss index, we can accurately quantify the waste heat utilization performance of the equipment system.

[0058] This includes the scope of capability improvement, which refers to the range of improvement in waste heat recovery efficiency or energy-saving effect that the corresponding waste heat utilization method can achieve in the equipment system, such as the practicality of the technical means corresponding to the waste heat utilization method for waste heat utilization.

[0059] This includes the intensity of the effect of the corresponding waste heat utilization method in the equipment system. The intensity of the effect of the waste heat utilization method is the actual effect of the corresponding waste heat utilization method in the system. It reflects the actual contribution of the waste heat utilization method to the system's energy saving or waste heat recovery. It can be represented by the equipment system's feedback (such as preference) on each waste heat utilization method.

[0060] This involves a selection index, which represents the probability of the equipment system choosing each waste heat utilization method.

[0061] By assessing the scope and intensity of capacity enhancement, we can quantify the performance and potential of each waste heat utilization method for the equipment system. This allows us to reasonably evaluate the probability of the equipment system choosing each waste heat utilization method, and ultimately helps to accurately determine the most likely waste heat utilization method for the equipment system.

[0063] This embodiment describes the specific steps for determining the selection index corresponding to each of the multiple waste heat utilization methods based on the capacity enhancement range and capacity intensity of each method.

[0064] This involves operational complexity, which refers to the complexity of implementing the corresponding waste heat utilization method, including technical requirements, equipment installation, and maintenance difficulty. The higher the operational complexity, the higher the resources and costs required to implement and maintain the waste heat utilization method.

[0065] This includes the effect duration parameter, which refers to the length of time or stability of the effect of the corresponding waste heat utilization method within the equipment system. The effect duration parameter reflects the effectiveness and reliability of the waste heat utilization method over time.

[0066] By further considering operational complexity and duration parameters on the basis of capacity enhancement range and capacity intensity, it is possible to quantitatively evaluate the feasibility of each waste heat utilization method for the waste heat utilization of the equipment system, as well as its long-term benefits. Thus, by comprehensively considering multiple factors, it is possible to fully and accurately determine the most likely waste heat utilization method for the equipment system.

[0067] As an optional embodiment, the energy demand parameters corresponding to the equipment system are determined based on the output parameters and energy consumption parameters, including: when the equipment system includes a power system, the output parameters include power generation, and the energy demand parameters include power generation demand parameters, determining the power transmission loss corresponding to the power system; and determining the power generation demand parameters corresponding to the power system based on the power generation, power transmission loss, and energy consumption parameters.

[0068] This embodiment describes the specific steps for determining the energy demand parameters corresponding to the equipment system based on production parameters and energy consumption parameters.

[0069] This involves the power system, which is the equipment system corresponding to power operation (such as power generation, transmission, and distribution).

[0070] This includes power generation, which is the amount of electricity that the power system can provide within a predetermined time.

[0071] This includes power generation demand parameters, which are used to reflect electricity demand, such as electricity consumption.

[0072] This includes power transmission losses, which are losses of electricity during transmission, such as losses caused by the resistance of the transmission line.

[0073] By calculating power transmission losses, the actual amount of electricity lost during transmission can be determined. By determining power transmission losses and combining them with power generation and energy consumption parameters, power generation demand parameters can be calculated, enabling precise quantification of the actual power generation demand of the power system during operation.

[0074] As an optional embodiment, the power generation demand parameters corresponding to the power system are determined based on power generation, power transmission loss, and energy consumption parameters, including: when the power system includes multiple power devices, determining the power generation efficiency corresponding to each of the multiple power devices; and determining the power generation demand parameters corresponding to the power system based on the power generation efficiency, power generation, power transmission loss, and energy consumption parameters corresponding to each of the multiple power devices.

[0075] This embodiment describes the specific steps for determining the power generation demand parameters corresponding to the power system based on power generation, power transmission losses, and energy consumption parameters.

[0077] This includes power generation efficiency, which is the efficiency with which electrical equipment converts input energy (such as coal) into electrical energy.

[0078] By determining the power generation efficiency of each electrical device, a quantitative assessment of the energy conversion efficiency of each device in actual operation can be achieved. Combined with power generation and power transmission losses, a more comprehensive assessment of the total power generation demand of the power system in actual operation can be made.

[0079] As an optional embodiment, after determining the waste heat utilization parameters corresponding to the equipment system based on energy demand parameters, consumption characteristic parameters corresponding to multiple energy types, and waste heat loss index, the method further includes: determining the carbon emission impact index corresponding to each of the multiple energy types; determining the initial carbon emission parameters corresponding to the equipment system based on the carbon emission impact index corresponding to each of the multiple energy types and energy consumption; determining the environmental parameters corresponding to the equipment system; and correcting the initial carbon emission parameters based on the environmental parameters and waste heat utilization parameters to obtain the target carbon emission parameters corresponding to the equipment system.

[0080] This embodiment describes the specific steps after determining the waste heat utilization parameters corresponding to the equipment system based on energy demand parameters, consumption characteristic parameters corresponding to multiple energy types, and waste heat loss index.

[0081] This includes a carbon emission impact index, which measures the impact of each type of energy consumption on carbon emissions. It includes a first emission factor and a second emission factor, where the first emission factor is the carbon emission factor from energy combustion and the second emission factor is the emission factor from the product production process.

[0082] This involves initial carbon emission parameters, which are the carbon emissions of the equipment system initially determined based on the carbon emission impact index and energy consumption of each energy type. These initial carbon emission figures do not consider waste heat utilization and other environmental factors (such as environmental parameters) and require further accurate quantification.

[0083] This includes environmental parameters, which are used to represent the environmental conditions and factors related to the operation of the equipment system, including carbon absorption.

[0084] By determining the carbon emission impact index for each energy type (including combustion carbon emission factor and process emission factor), the ability of each energy type to affect carbon emissions can be accurately assessed. Combined with energy consumption, the initial carbon emission parameters of the equipment system can be preliminarily determined. Furthermore, environmental parameters (such as carbon absorption) and waste heat utilization parameters can be considered to correct the initial carbon emission parameters, thereby improving the accuracy of carbon emission determination for the equipment system.

[0085] For example, the target carbon emission parameter can be obtained by subtracting the carbon emission impact index from the initial carbon emission parameter to obtain the carbon absorption.

[0086] Based on the above embodiments and optional embodiments, an optional implementation method is provided, which is described in detail below.

[0087] In related technologies, equipment systems can improve energy efficiency by utilizing waste heat, thereby helping to reduce energy procurement costs and production costs, and decrease carbon emissions. Therefore, to maximize energy efficiency, it is necessary to accurately assess the waste heat utilization parameters of the equipment system. However, in related technologies, there is a technical problem of inaccurate determination of waste heat utilization parameters for equipment systems.

[0088] There is currently no effective solution to the above problems.

[0089] In view of this, the optional embodiments of the present invention provide a method for determining the waste heat utilization parameters of an equipment system, which can also be called a method for determining the waste heat utilization potential of an equipment system.
