Description
Technical Field
The invention relates to the technical field of comprehensive energy, in particular to a public information model construction method and device for a comprehensive energy digital platform.
Background
The comprehensive energy physical world is a complex system consisting of devices in different energy types (gas, electricity, cold, heat and the like) and different energy fields (load, source, network and storage), and the digital description of the system needs a universal information model, so that objects and related characteristics of the different energy types and the different energy fields can be described by adopting a uniform description framework, and the digital basis of the energy world is laid.
The energy field has long been studied in terms of public information models. In the next half of 2010, an IEC61970/61968 public information model (hereinafter referred to as electric power CIM) is formally laid as the status of the core standard of the smart grid, as published by the IEC smart grid standardization route map version 1.0. The method is related to the fact that the power CIM is born as an internal database model of an EMS and an SCADA system. This approach has the following features:
(1) the range of the model framework is very complete, and the model framework can be suitable for describing different dimensional information of various different objects in the real world, including but not limited to physical information and business information. Because the business information and the physical information belong to information with different dimensions, the concept definition and the data expression of the business information and the physical information follow different paradigms and rules, and when the business information and the physical information are forcibly unified into a model framework, the confusion of information users can be caused. For example, the concept "class" of the model may be embodied as a classification of energy physical devices when describing physical world information, and may be embodied as a classification of completely different meanings when describing business information. This is not a problem at the database level, but can be very cumbersome in the instantiation process.
(2) The basic semantic objects (namely, the underlying concepts) are very universal, can be suitable for describing various different objects in the real world, and are not limited to describing the energy physical world. But also because of the universality, the underlying concept does not directly reflect the characteristics of the energy physical world, which brings a larger operation space for the application of the model. Even if the description is completely directed to the energy physical world, users of the model can completely evolve different entity concepts and determine different description categories based on the requirements and understanding of the users. This is not beneficial to establishing a uniform information model facing different fields.
From the practical application perspective, the energy physical world needs a more targeted information model framework, and needs a clear basic semantic object (bottom-level concept) capable of summarizing and abstracting the energy physical world, and the information model should design a semantic expression mode around the bottom-level concept.
In the field of automatic control, month 5 2014 in the united states a non-profit organization operating a project named Haystack, aimed at developing semantic modeling solutions for data related to intelligent devices, which is mainly directed to objects involved in building automation systems such as building equipment systems, automation and control devices, sensors and sensing devices.
The label model method of the Haystack is a semantic expression method which is worth reference, but the oriented field is the field of building automation, the description view angle of the Haystack is different from that of the energy physical world, and the related physical object category is also different, so that the Haystack cannot meet the information model requirement of the energy physical world.
Therefore, the invention provides a public information model construction method and a public information model construction device for an integrated energy digital platform, and solves the problem of standardized description of the energy physical world.

It is to be understood that the embodiments described are only a few embodiments of the present disclosure, and not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present specification without any creative effort belong to the protection scope of the present specification.
Fig. 1 is a schematic flowchart of a method for constructing a common information model for an integrated energy digitization platform according to an embodiment of the present invention.
As shown in fig. 1, a method for constructing a common information model for an integrated energy digitization platform according to an embodiment of the present invention may include the following steps:
and step 110, acquiring parameters of the public information model to be constructed, wherein the parameters are acquired through energy, energy equipment, an energy flow network and an energy system.
Aiming at the step, the comprehensive energy physical world is decomposed into four model elements of energy, energy equipment, an energy flow network and an energy system.
And 120, respectively constructing an energy information model, an energy equipment information model and an energy flow network information model according to the parameters.
In this step, the process of establishing three information models is described:
1. the method for constructing the energy information model specifically comprises the following steps:
s21, determining the energy type, and performing a first preset encoding on the energy type;
the method for determining the energy category may be performed by classifying energy substances, wherein the energy substances may include at least one of energy substances such as ac, dc, gas, fuel, steam, hot water, cold water, flue gas, biomass, and air, and performing a first preset code for each category of the energy categories.
S22, using preset codes of each type of energy classification as first metadata of the comprehensive energy digitization platform, and storing the first metadata;
s23, constructing the energy information model based on the first metadata, wherein the first metadata comprises an energy inlet identification of an energy device and an energy medium type of an energy outlet.
Further, firstly, energy classification is carried out on energy substances, and a first preset code is carried out; secondly, using preset codes of each type of energy classification as first metadata of the comprehensive energy digitization platform, and storing the metadata; and finally, constructing the energy information model based on the first metadata, wherein in the energy information model, the first metadata describes energy medium types of an energy inlet and an energy outlet of the energy equipment in the integrated energy physical world.
Illustratively, the most basic and central elements of the physical world of integrated energy are various energy substances meeting the requirements of industrial and civil energy, and the energy substances include various primary energy sources and secondary energy sources, energy substances such as steam, cold and hot water and the like produced by the primary and secondary energy sources, energy substances such as flue gas and the like derived in the energy conversion process, and other energy substances consumed in the process of producing domestic energy, such as compressed air and the like.
For electricity in secondary energy, the present invention determines its classification into two categories of alternating current and direct current, and at the same time, determines cold water and hot water produced by primary and secondary energy for production and life as one energy type: hot and cold water, and other energy types including, but not limited to, gas, fuel, steam, flue gas, biomass, air, etc. And then constructing an energy information model according to the steps.
In some embodiments, the energy source substance may be classified and encoded as follows (a standard set of codes for establishing energy classification, the codes being in capital english letters), for example as follows:
| name of energy substance | First preset code |
| Alternating current | ACE |
| Gas combustion | GAS |
| Steam generating device | STE |
| Cold and hot water | WAT |
| Flue gas | FGS |
| Fuel oil | OIL |
| Biomass | BIO |
2. The method for constructing the energy equipment information model specifically comprises the following steps:
firstly, classifying the energy equipment, and carrying out a second preset code, wherein the second preset code comprises a type code of the energy equipment classification, an energy inlet identifier of any type of energy equipment and a type code of an energy outlet; then, carrying out attribute coding through a third preset code for each type of energy equipment; secondly, taking a second preset code and a third preset code of each type of energy equipment as second metadata of the comprehensive energy digitization platform, and storing the second metadata; and finally, constructing the energy equipment information model based on the second metadata.
Illustratively, all energy substance production, transport, distribution, consumption takes place in specific physical devices, which are collectively referred to herein as energy plants. Each energy source device must be associated with one or several energy sources. The energy devices constitute a second core element of the common information model.
The energy equipment information model construction process is as follows: classifying physical devices (energy equipment) for producing, conveying, distributing and consuming the energy substances, and establishing a set of standard codes for classifying the energy equipment; the classification of energy devices follows two classification principles: a. the principle of non-disassembly, namely, traversing all the entity devices according to the components of the actual physical device during classification, wherein each type of equipment is an integral formed by a plurality of components, and the public information model is only regarded as one type of equipment; b. the description boundary of the equipment only comprises a functional boundary for completing the work task of the equipment per se, and does not relate to information related to the communication between the equipment and the outside and the realization of purely serving the automatic control.
The standard code of the energy device is constructed by capitalized English letters, and the examples are as follows:
(2) and establishing standard description of an energy inlet and an energy outlet of each type of energy equipment, wherein the standard description comprises the type and the quantity of the energy medium of the energy inlet and the type and the quantity of the energy medium of the energy outlet, and the description of the type of the energy medium adopts energy classification metadata.
By way of example, a standard description of the energy inlet and outlet of an energy device "electric refrigerator" is as follows:
energy inlet of electric refrigerator: 1 ACE, 2 WTE (one is chilled water and one is cooling water)
Energy outlet of electric refrigerator: 2 WTEs (one is chilled water and one is cooling water)
(3) And standard codes of the energy equipment classification are used as metadata of the integrated energy digitization platform, and the codes are used for describing the types of the energy equipment.
(4) And establishing a standard code for attribute description of each type of energy equipment.
For each type of energy equipment, the attributes are divided into measurement attributes and inherent attributes, and standard codes metric and attr are used for representing the two attributes. Each type of equipment establishes detailed classifications of the measured attributes and the inherent attributes thereof according to the energy equipment classification principle, and classifies and encodes the attributes, which is exemplified as follows:
the measurement attribute classification of the Heat Pump (HP) class includes, but is not limited to, the following:
each of the above-mentioned measurement attribute classifications represented by each code also contains a series of attributes, including but not limited to value type, control attribute of measurement point, value unit, multiplier of value, reasonable range of measurement value, etc., which describe the general characteristics of the measurement classification in practical application.
The intrinsic properties are similar to the measured properties, each code represents an intrinsic property class, and each intrinsic property itself also contains a series of properties including, but not limited to, value type, value unit, etc., which also describe the general characteristics of the intrinsic property class in actual application.
(5) The standard codes of each type of energy equipment are used as metadata of the comprehensive energy digitization platform, and the metadata are stored and maintained in a database of the comprehensive energy digitization platform;
(6) in an Internet of things link of the energy equipment, the attribute description metadata is adopted to carry out attribute description on the energy equipment.
When the digital platform establishes a digital mirror image of the energy equipment and continuously collects dynamic data of the energy equipment, the attribute metadata is adopted to describe static data and dynamic data of the energy equipment. Each data regarding the energy device can be interpreted using the above-described metadata.
For example, when an object is connected to an electric refrigerator in a real project, attribute metadata of an electric refrigerator (ECR) class is used to describe static data and dynamic data of the connected object. Firstly, metadata of attr of the ECR is used for describing static information of the electric refrigerator, such as product model, brand, rated refrigerating capacity and the like, and secondly, metadata of metric of the ECR is used for describing dynamic information of the electric refrigerator, such as refrigerating power, evaporator outlet water temperature and the like, and each piece of data describing the electric refrigerator corresponds to one metadata code.
3. The method for constructing the energy flow network information model specifically comprises the following steps:
establishing connection relations of energy inlets and/or energy outlets of different energy devices aiming at the same type of energy substances; and constructing an energy flow network information model based on the connection relation. The energy inlet and/or the energy outlet are marked with different marks.
As can be understood by those skilled in the art, energy substances circulate among energy devices in the production, transportation, distribution, consumption and other links to form an energy flow network, and the flow network describes the connection structure of the integrated energy world and is the third core element of the public information model.
Illustratively, the network is shown in FIG. 2 for energy flow. As shown in fig. 2, the energy inlet or outlet is represented by dots of different colors. By way of example, assuming that the energy plant is a GAS turbine, its GAS energy inlet can be represented by a yellow dot, its ACE energy outlet can be represented by a black dot, its high temperature flue GAS FGS energy outlet connected to the flue GAS FGS inlet of the residual heat absorption chiller whose cold water WAT outlet is connected to the WAT inlet of the chilled water line whose chilled water WAT outlet is connected to the chilled water WAT inlet of the chilled water valve, these connections represent the structure of an energy flow network, and the energy plants in this structure (e.g., four different types of plants included in the above figure) define the boundaries of the energy flow network.
And step 130, constructing the energy information model, the energy equipment information model and/or the energy flow network information model into the public information model according to the application scene information.
Specifically, a preset training model scheme is loaded according to application scene information; determining information for constructing the public information model by using the preset training model scheme; and constructing the energy information model, the energy equipment information model and/or the energy flow network information model into the public information model based on the information of the public information model.
Illustratively, an energy system is an ensemble of several energy devices combined through an energy flow network. Energy systems exhibit more abundant characteristics than energy devices,
the information model of the energy system comprises two levels: a complete information model and an equivalent information model. In this step, a complete information model is established. The complete information model of the energy system describes the energy devices contained in the system, the information of the devices and the information of the energy flow network formed by the energy devices.
According to another embodiment of the present invention, the present invention may further include the steps of:
classifying the public information model to obtain the category of the public information model; performing fourth preset coding on the category of the public information model and the inlet and the outlet of the energy system; setting a fifth preset code, and coding the energy system by using the fifth preset code; taking the fourth preset code and the fifth preset code as third metadata of the comprehensive energy digitization platform; and constructing an energy system information model of the public information model based on the third metadata. The energy system information model of the public information model is an equivalent information model of the energy system.
The equivalent information model of the energy system can be a model for simplifying the description of the energy system, the description method of the equivalent information model is consistent with the description method of the equipment information model, namely, the energy system is used as an energy equipment for description, the description comprises the attribute description of the energy system and the description of an energy inlet and an energy outlet of the energy system, and the inlets and the outlets are the inlets and the outlets of other energy equipment, and the description of a more complex energy flow network is completed by adopting the information model method;
the classification code of the energy system that establishes the criteria for the equivalent information model may be exemplified as follows:
the classification of energy systems and their encoding includes, but is not limited to, the following:
| name of energy System | Fifth preset code |
| Universal energy station | UES |
| Photovoltaic station | PVS |
| Heat supply station | HPS |
| Energy utilization system | EMS |
| Distribution network system | DMS |
| Transformer substation | SAS |
| Energy storage station | ESS |
| Integrated system | COMP |
| Power distribution station | PDS |
| Switching station | SS |
| Heat exchange station | HES |
(5) Establishing a standard code for attribute description of each type of energy system;
(6) the classified codes of the energy systems and the attribute codes of each type of energy systems are used as metadata of the comprehensive energy digital platform;
(7) in the link of the Internet of things of the energy system, the metadata is adopted to classify and describe the energy system.
Based on the process, for example, in a certain industrial park, a centralized heat supply station supplies heat to all enterprises in the park, the park is divided into a south area and a north area, and each area is provided with a heat exchange station which is responsible for converting high-temperature hot water produced by the heat supply station into hot water with lower temperature and conveying the hot water to enterprise plants in the service area. In the process of the internet of things, HPS codes are adopted to describe heat supply stations, inherent attribute metadata of the HPS are adopted to describe information such as total assembly power and total heat supply amount (design value), measurement metadata of the HPS are adopted to describe dynamic information such as real-time total supply hot water flow and hot water temperature, and HES codes and attribute metadata thereof are adopted to describe static and dynamic information of the two heat exchange stations.

As shown in fig. 3, a common information model construction apparatus 300 for an integrated energy digitization platform according to an embodiment of the present invention may include an acquisition module 310, a first construction module 320, and a second construction module 330.
