the oil and gas pipeline regulation and control business support system and the implementation method thereof have four kinds of regulation and control business support of oil and gas pipeline process analysis, logic control, operation analysis and storage and marketing analysis based on information interaction specifications of service calling of a service bus of an SCADA system and taking an oil and gas pipeline regulation and control model as system configuration, data interaction and data representation, realize real-time data acquisition, business analysis result storage and business man-machine interaction depending on the SCADA system.
An implementation method of an oil and gas pipeline regulation and control business support system comprises the following steps:
1) the method comprises the steps of performing analysis, calculation, regulation and control interactive operation on the whole regulation and control service of the four types of pipelines, namely crude oil, product oil and natural gas pipelines of an oil and gas pipeline regulation and control service support system, performing logic control, running analysis and storage and marketing analysis.
Aiming at the actual working requirement of centralized regulation and control of the oil and gas pipeline, on the basis of data acquisition, real-time processing, data storage, man-machine interaction and the like of an SCADA system of the oil and gas pipeline, the regulation and control service of the oil and gas pipeline is divided into four functions of process analysis, logic control, operation analysis and storage and marketing analysis according to the service requirement of a regulation and control personnel on the regulation and control pipeline.
The process analysis service function is the basic process data analysis and calculation provided for ensuring the production and operation of the oil and gas pipeline, and can convert the pipeline field operation data into the relevant data of the regulation and control service, and specifically comprises the functions of the finished oil sequential delivery analysis, the hydraulic slope drop analysis, the pipeline differential pressure flow analysis and the pipeline high point pressure analysis.
The service functions of the logic control class can realize the logic sequence of normal operation of the pipeline and the logic protection under the unexpected condition, and mainly comprise the functions of full-line start transmission, ESD (emergency shutdown system), water hammer protection and the like.
The operation analysis type service function can realize the analysis and judgment of the deep operation state of the pipeline, and specifically comprises the functions of compressor performance analysis, pipeline section conveying efficiency calculation, operation state evaluation and optimization and the like.

The oil and gas pipeline regulation and control business support system can perform data analysis, calculation and man-machine interaction respectively aiming at various businesses of liquid pipelines (crude oil and finished oil) and gas pipelines. The regulation and control business support system performs data fusion on basic data through a pipeline model on the basis of real-time data of the SCADA system, combines data and information of other digital systems, calculates various data through a scientific and reasonable calculation formula according to the functional requirements of each specific business analysis, and displays the various data to a dispatcher in the form of visual pictures such as graphs, tables, graphs and the like on a human-computer interface system of the SCADA system.
2) And the regulation and control business support system is registered on the SCADA system service bus in a background service form and calls the SCADA system service.
The construction of the oil and gas pipeline regulation and control business support system depends on the architecture of SCADA system software, and the openness and expansibility on the system architecture are realized by adopting a service-oriented architecture and a service bus. As shown in fig. 2:
in the figure, a service bus-based architecture of the SCADA system is shown, and typical functions of the SCADA system, such as data acquisition, data processing, data storage, and the like, all adopt a modular design and are registered as a service on the service bus. In order to ensure the openness of the system, auxiliary functions such as authority, events, logs, system management and the like are also uniformly packaged into a service group book to be arranged on a service bus for uniform calling of other modules in the system. The model service realizes the business-oriented encapsulation of data in the system through a series of model definition and engineering instantiation objects.
3) The regulation and control business support system realizes other related functions such as model configuration, real-time data acquisition, result data storage, man-machine interaction and the like by using the SCADA system, and only needs to realize the analysis and calculation of business data.

On the basis of the pipe network connection hierarchical model, data related to a pipe network transmission process and regulation and control business are further abstracted into model elements and attributes thereof, and a uniform oil and gas pipeline regulation and control representation model is formed. The pipeline regulation and control model realizes the uniform representation of the regulation and control all-service related data and becomes a data basis of the analysis and calculation of each correlation of the regulation and control support system. The pipeline regulation model comprises the following model elements: a pipe network model, a pipe section model, an inlet and outlet model, a topological point model, a user model, a tank area model, a tank model, a gasifier model, a tank inlet and outlet model and the like.
The regulation and control model is an overall abstraction from the integral petroleum oil and gas pipe network of China to each detail of the pipeline, and can realize the quick query of the process data and the feedback of the calculation result. As a data bridge for analyzing and calculating each regulation and control service, the pipeline regulation and control model has very high requirement on the integrity of the self definition. In order to ensure the integrity of the pipeline regulation and control model, the pipeline regulation and control model fully embodies the inheritability and the expandability in software engineering design, can define and configure a pipeline example as required in the software application process, can quickly traverse each device, sensor and process value under the model through an example handle of a specific pipeline section model, and quickly returns a calculation result to finish data display.

6) And the man-machine interaction of the service analysis data is realized by the configuration interactive picture of the universal data display control in the SCADA system.
A human-computer interaction mode for regulating and controlling a business analysis and calculation result is analyzed, and a data display form of a two-dimensional curve, a histogram and a data record table and a data display form of fig. 3 are determined.
