[0003] The Chinese patent with publication number CN209483446U discloses a distributed biomass energy combined heat and power system. It mainly uses a waste heat utilization heating system to fully utilize the excess high-temperature gas generated by the biomass gasification system, save energy, avoid energy waste, and make more full use of energy. At the same time, the distributed biomass energy combined heat and power system has a high energy utilization rate and can achieve energy recycling.

Although the above patent solves the problem of energy utilization, there are still the following problems in actual operation:

This method can reduce unnecessary calculations and data processing, thereby improving data processing efficiency. At the same time, through the quality evaluation module, the system can perform quality evaluation on the filtered target historical fault data.

[0151] In addition, by evaluating the quality of the target historical fault data, the system can discover potential failure modes and trends. This helps to more accurately identify the weak links and potential problems of the equipment, and provide more targeted suggestions and guidance for the maintenance and repair of the equipment. By improving the accuracy of fault detection and data screening, the system can reduce unnecessary maintenance work and reduce maintenance costs. At the same time, by continuously monitoring and evaluating the health of the equipment, it can avoid large-scale repairs or replacement of parts due to ignoring certain potential problems, further saving maintenance costs.
[0152] In summary, the above technical solution achieves more accurate fault data screening, more reliable quality assessment, more accurate fault probability assessment, more targeted equipment maintenance, lower maintenance costs and better user satisfaction in terms of performance indicators. These technical effects help improve the overall operating efficiency and reliability of the equipment. At the same time, it can effectively screen out interference data in historical fault data, thereby effectively improving the representation of the screened historical fault data for the equipment's own operating faults.
[0153] Specifically, the quality assessment module includes:
[0154] The difference parameter acquisition module is used to perform fault data difference evaluation on the target historical fault data corresponding to the waste heat boiler, absorption chiller, heat exchanger and energy converter of the generator set, and obtain the difference parameters corresponding to the target historical fault data of the waste heat boiler, absorption chiller, heat exchanger and energy converter of the generator set; wherein the difference parameters are obtained by the following formula:
[0155]
[0156]
[0157] Where C represents the difference parameter corresponding to the target historical fault data of the generator set waste heat boiler, absorption chiller, heat exchanger and energy converter; r represents the number of fault data contained in the target historical fault data; X ti represents the operating parameter characterization data corresponding to the i-th target historical fault data; R represents the difference factor;
[0158] A difference comparison module, used for comparing the difference parameter with a preset difference parameter threshold;
[0159] A quality determination module, configured to determine whether the target historical fault data meets the quality requirements when the difference parameter exceeds a preset difference threshold;
[0160] The fault data secondary screening module is used to determine that the target historical fault data does not meet the quality requirements when the difference parameter does not exceed the preset difference threshold, and delete the fault data closest to the normal operating data in a group of historical data whose fault data difference values between historical fault data with adjacent fault timestamps in the target historical fault data are lower than the data difference threshold, so as to obtain the historical fault data finally used for fault probability assessment.
[0161] The technical effect of the above technical scheme is: since historical fault data often contain two adjacent equipment operation failures caused by the same fault factor not being properly eliminated, the historical fault data generated by the failure of the previous fault problem not being eliminated and resulting in the same problem occurring again within a short period of time cannot fully reflect the occurrence of the equipment's own operation failure because it is not a re-occurrence of the equipment itself after the fault has been eliminated, but a continuation of the original equipment failure caused by improper human operation and maintenance. Therefore, the fault data information corresponding to the secondary fault caused by improper human operation and maintenance is actually interference data for a reasonable fault assessment of the equipment's own fault generation situation. In the traditional fault assessment process, this interference data is often also used for fault probability assessment, resulting in low accuracy of equipment fault assessment and large errors.
[0162] Therefore, the above method can effectively prevent the problem that the same fault will occur again in the future because the fault itself was not properly repaired and the system is still in operation, but the original fault cause is not solved within a certain period of time. By effectively improving the accuracy of screening historical fault data, the accuracy and rationality of equipment failure probability assessment can be effectively improved.
[0163] At the same time, through the difference parameter acquisition module, the system can perform fault data difference evaluation on the target historical fault data and obtain the corresponding difference parameters. This difference evaluation can more accurately reflect the characteristics and changes of the fault data, thereby improving the accuracy of the fault data quality evaluation. Through the difference comparison module and the fault data secondary screening module, the system can screen the target historical fault data according to the preset difference threshold and data difference threshold. This screening method can further optimize the selection of fault data and improve the quality of fault data. In addition, through the quality judgment module, the system can determine whether the target historical fault data meets the quality requirements. Only historical fault data that meets the quality requirements will be used for fault probability evaluation. This quality evaluation can further improve the reliability and accuracy of fault probability evaluation. At the same time, by using difference parameters for screening and quality evaluation, the system can reduce unnecessary calculations and data processing and reduce calculation complexity. This optimization can improve the processing efficiency of the system and reduce resource consumption.
[0164] On the other hand, by conducting quality assessment and screening of target historical fault data, the system can discover potential failure modes and trends. This helps to more accurately identify the weak links and potential problems of the equipment, and provide more targeted suggestions and guidance for the maintenance and repair of the equipment. By improving the accuracy of fault detection, data screening, and quality assessment, the system can reduce unnecessary maintenance work and reduce maintenance costs. At the same time, by continuously monitoring and evaluating the health status of the equipment, large-scale repairs or replacement of parts caused by ignoring certain potential problems can be avoided, further saving maintenance costs. By improving the operating stability of the equipment and reducing maintenance costs, the system can provide users with a better service experience. This helps to improve user satisfaction with the equipment and system and enhance user loyalty.
[0165] In summary, the above technical solutions have achieved more accurate fault data quality assessment, more optimized fault data screening process, more reliable fault probability assessment, lower calculation complexity, more targeted equipment maintenance, lower maintenance costs and better user satisfaction in terms of technical effects. These technical effects help improve the overall operating efficiency and reliability of the equipment.

[0180] Specifically, by processing and standardizing the thermal energy, electrical energy and cold energy data through the energy recovery statistics module, the capacity converter can improve data quality, enhance data comparability, provide decision support, optimize energy management and promote energy recycling. The data preprocessing steps include data cleaning, processing missing values and deleting duplicate values, which can effectively improve the accuracy and reliability of data and reduce the impact of abnormal values and redundant data on analysis. Data standardization can unify the data from different sources and units to make them comparable and easy to analyze and compare. Standardized data is easier to analyze and visualize, and can more intuitively reflect the distribution and trend of thermal energy, electrical energy and cold energy data. Through the unique coding and labeling of the energy recovery storage module, the recycling equipment and storage attributes corresponding to each target renewable energy data can be clearly identified, which is convenient for unified management and query of data. At the same time, data capacity confirmation and memory remaining capacity confirmation can ensure that there is sufficient storage space for data and avoid data overflow and loss. By real-time monitoring and recording of target renewable energy data, it is possible to timely understand energy recovery, storage and use, and improve the level of intelligent energy management. Through unique coding numbers and data management optimization, the security of target renewable energy data can be enhanced, avoiding illegal acquisition and use of data, and ensuring the security and stability of the energy system.
[0181] In order to solve the problem in the prior art that after the energy recovery scheme in the combined cooling, heating and power generation is completed, the recovered energy data is not further compared with the preset standard energy data, which leads to the reduction of the complementarity of renewable energy, please refer to Figure 1 and Figure 2 , this embodiment provides the following technical solutions:

[0194] The size of the non-overlapping area is converted into a numerical value, and after the conversion is completed, the numerical value of the non-overlapping area is obtained;
[0195] Finally, the overlapping data of standard energy values and actual energy values as well as the numerical data of non-overlapping areas are used to formulate a standard plan.
[0196] Specifically, the data is displayed in an intuitive way through the graphic table formulation module, which is convenient for decision makers to quickly understand the recovery, storage and use of energy. Through the tabular data, the distribution, trend and comparison of various energy data can be clearly seen. Sending the tabular data to the energy transmission and distribution center can realize information sharing, so that relevant departments and personnel can understand the energy data in a timely manner and work together. This helps to improve work efficiency and strengthen communication and collaboration between departments. By comparing the standard energy values with the actual energy values through the energy plan formulation module, the difference between the actual situation of energy transmission and distribution and the preset rules can be clearly understood. This helps to discover bottlenecks and problems in the energy transmission and distribution process, optimize the configuration and use of energy, and improve the efficiency and stability of energy transmission and distribution. Through the formulation of standard solutions, scientific and accurate energy transmission and distribution data support can be provided to decision makers.
