Description

FIELD OF THE INVENTION

The invention relates to the field of dispatching flows of oil and oil products, and in particular to dispatcher training complexes, which are intended for initial training and periodic training (training) of operational dispatch personnel. An individual dispatching simulator (hereinafter - IDT) can be used in dispatching divisions of operating enterprises of main oil pipelines to conduct training for dispatchers at workplaces in order to form and consolidate skills in managing a main oil pipeline both in regular and emergency situations. Also, an individual dispatching simulator can be used in centers that train dispatching personnel of oil trunk pipeline enterprises, including as part of a collective dispatching simulator.

State of the art

The well-known training complex of the Vesta-TP dispatcher for organizing primary and periodic training of operational and dispatch personnel simulating the operation of the main oil pipeline (hereinafter referred to as the MN) and the main gas pipeline (see http://www.gubkin.ru/departaments/university_departments / iiept / practical_realization / supervisory_control /).

The Vesta-TP training complex is designed to form the skills of managing gas pipelines among dispatching personnel, conduct computational experiments to simulate various emergency or emergency situations during the operation of gas transmission systems and the controls introduced by the dispatcher, and conduct emergency training exercises for training tasks developed using gas transmission systems as an example located in the area of responsibility of this dispatching service.

The disadvantage of the Vesta-TP training complex is that the dispatcher’s automated workstation in the simulator does not fully correspond to his real workplace.

The well-known training complex developed by LLC NIRSA-service (http: //www.nirsa. Ru.).

The drawback of the NIRSA-service development is that it uses a mathematical model simulating the operation of the MN of one configuration, which provides much less functionality in terms of simulated situations and modes. The mathematical model of the NIRSA-service development contains configurations representing one or two hydraulically connected technological sections, each of which consists of a head and two intermediate oil pumping stations (hereinafter referred to as NPS). In addition, the above dispatching simulators are designed to provide training for NPS operators and contain a simplified configuration (training model) of the MN site. The mathematical model of the data of control simulators excludes the possibility of making changes to the configuration of the MN circuit. Thus, the existing dispatching simulators do not allow simulating a number of possible situations at the MN facilities (turning on / off looping, paging / discharge points, etc.) and organizing high-quality training for dispatchers using the MN configuration identical to the oil pipelines that will be manage dispatchers in real conditions.

The closest in functionality due to the active use of the components used in the real control system of the pipeline is the dispatch simulator used by Vostoknefteprovod LLC (see http://www.energoavtomatika.ru/index.php/ru/menu- reviews / 92-review-vsto).

The support system for the dispatcher and the simulator PC is implemented on the basis of Cassandra mathematical modeling software. The simulator includes a Leak Detection Status Module (SDS), which real-time continuously monitors the tightness of the monitored sections at all pipeline operating modes, including transients and the stopped pipe mode. Having the ability to control the technological facilities of the pipeline, modeling changes in station protection allows using the Simulator PC to test the control system, train dispatch personnel and calculate technological modes.

The well-known simulator uses the Cassandra modeling system, which is the most functional at the moment, and provides training for personnel in conditions that are closest to the real ones for the enterprise, but has the following disadvantages. In the dispatching simulator used by Vostoknefteprovod LLC, there is no educational and methodical part of the software complex, since the simulator is implemented on the basis of subjective assessment by the instructor of the implementation of the educational tasks of the trained dispatcher.

The virtual server 1.3 of simulating SDKU (fi. 2) is designed to provide informational interaction between subsystems 3.1 for visualizing the status of TO and TP and subsystem 3.3 for monitoring modes of Workstation 3 automated workstation, as well as server 1.5 of the mathematical model and algorithms of operation of automation systems of MN that perform the functions of virtual technological process and virtual system MN. Since a number of software modules of automated workplace of student 3 are actually operated by industrial dispatching personnel, the SDKU simulation server 1.3 is aimed, first of all, at simulating the operation of the SDKU TM data input / output subsystem for transmitting technological data of the TO and TP status visualization subsystem 3.1 and the program module 3.2 hydraulic slope.

The virtual server 1.3 simulating SDKU includes a software module 1.3.1 OPC server, a subsystem 1.3.2 for processing data and preparing signals for an OPC server, a software module 1.3.3 for visualizing the status of TO and TP.

The software module 1.3.1 OPC server is the main component of the SDKU simulation server and is designed to provide real-time data exchange with the following software modules (acting as OPC clients): subsystem 3.1 for visualizing the status of maintenance and repair (SCADA forms of the GENESIS 32 system included in the AWP of the Trainee 3); software module 3.2 control of hydraulic slope, made on the basis of ASK "Hydroclone"; subsystem 3.3 mode control; subsystem 2.4 GUI AWP instructor.

The software module 1.3.1 OPC server is based on the software UForte OPC Toolkit. OPC server 1.3.1 supports the following protocols:

- OPC DA - for access to operational data;

- ODP HDA - for access to historical data;

- OPC A & E - to control events.

The OPC server 1.3.1 of the simulation server of the SDKU IDT contains many identifiers (tags) of the technological parameters of the nodes and / or equipment (hereinafter referred to as the address space), which exactly correspond to the technological parameters of the nodes and / or equipment registered by the SDKU of the enterprise on which the installation is planned simulator. The data source for the simulation server SDKU IDT is the server 1.5 of the mathematical model and algorithms of the automation systems MN, which at each calculation step generates the calculated value corresponding to the technological parameters of the MN. Thus, the address space of the OPC server 1.3.1 IDT must exactly match the address space of the OPC servers of the SDKU of the enterprise where this IDT is being implemented, which improves the efficiency of dispatch control of the operating modes of trunk oil pipelines and technological complexes by ensuring full functional simulation of the mode work of the technological complex of the pipeline.

Correspondence of the address spaces of the OPC signals will allow simulating the OPC signals of the enterprise SDKU about standard and emergency situations and reproducing the operation of the SDKU input / output servers. In addition, it will be possible to connect additional SDKU software modules that use this set of OPC signals in their work. The formation of the address space occurs at the start of the OPC server 1.3.1. The data source for the OPC server 1.3.1 is the subsystem 1.4.2 for storing technological data. Filling the address space with signal values is the task of the subsystem 1.3.2 data processing and signal preparation 1.3.1 OPC server.

When the corresponding event occurs, it makes a request. The data source is subsystem 1.5.1 of the mathematical model of MH and subsystem 1.5.2 of the automation and protection systems algorithms. The obtained values are transferred to the address space of the OPC server 1.3.1;

- transmission of telecontrol and teleregulation commands for the mathematical model of IDT. When implementing control actions by the trainee or instructor, the values of the corresponding signals are accepted by the OPC DA client. The obtained signal values are recorded in the subsystem 1.4.2 storage of technological data. At the same time, the program module 1.4.1 for managing and processing data generates the corresponding messages about updating the data, which are transmitted by means of the central dispatcher to the server 1.5 of the mathematical model of MN. In this case, the data is updated in the OPC server 1.3.1. The module for connecting the dispatching simulator to a real SDKU and providing historical technological data and events (not shown in the drawings) provides loading of normative and reference, passport information, operational parameters of the IDT mode, which are historical from the point of view of a real SDKU, and a list of OPC signals of the input server - output of SDKU in IDT XML files of a unified format are used.

Simulation of signals from the SDKU about standard and emergency situations is achieved by loading into the IDT a list of OPC tags of the actually operated SDKU using the program module 1.4.3 data import / export manager.

To provide screen forms, the capabilities of the subsystem 1.3.3 for visualizing the status of maintenance and repair are used.

GraphWorx software (Genesis 32) is used as the software for the subsystem 1.3.3 for visualizing the status of maintenance and technical data in the IDT. As source files of screen forms, mnemonic diagrams actually operated at the enterprise are used, which are stored in the IDT database.

With the help of the software module 1.3.3 visualizing the status of maintenance and repair, the following functions are performed: access to on-screen forms for viewing and modification taking into account user rights; updating and entering into the IDT modified screen forms.

Mode - “Training” - research mode.

The student must independently carry out work on the IDT for the oil pipeline system. Statistics on his work are not recorded by protocols, the student does not pass user authentication. Mode - “Guided Training” - training with the participation of an instructor.

This type of training should be carried out by an instructor without fixing the time of protocol events. The instructor must train the managing dispatcher in the correct "algorithm of actions" in normal and emergency situations at the BIM.

Mode - "Qualification Training".

This type of training should imply that the student carries out individual training under his account without the possibility of interference from the instructor. This type of training should be a rehearsal before passing the exam on "confirmation of competencies."

For this type of training, recording and issuing of the final grade should be carried out in accordance with the rules for the formation of the final grade.

Mode - "Confirmation of competencies."

This type of training should be designed to allow the supervisor to work independently with the final grade.

The statistics on the training should be recorded only in the following modes: “Qualification training”; "Confirmation of competencies."

Execution by the dispatcher of training tasks (UTZ), which are part of the UTZ library, previously developed and periodically updated.

In the "Training" mode, the IDT provides the following functions:

- registration of the dispatcher;

- selection of UTZ from the software module 1.2.3. When choosing the UTZ from the software module 1.2.3. UTZ libraries, data on MN prepared in advance for this UTZ is read, and the task for performing UTZ is displayed;

- execution by the dispatcher of the selected UTZ. In the process of performing UTZ, various diagnostic messages are generated, which are automatically displayed on the monitor screen. The dispatcher analyzes the data and identifies the situation on the MN. Depending on the situation and in accordance with the task of the training task, the dispatcher selects various controls for the MN objects;

- formation of a protocol for the implementation of UTZ All actions of the dispatcher in the process of performing UTZ are monitored and recorded. Based on this information, the execution protocol of the UTZ is formed;

- assessment of the performance of the UTZ dispatcher. At the end of the dispatcher’s work, the final score is calculated based on certain criteria and the UTZ execution protocol.

For each UTZ by means of the "User Interface", its own database is created, which includes the topology of the system, initial conditions of technological objects, and mode parameters.

When selecting a UTZ from a UTZ database, data on the MN prepared in advance for this UTZ is read.

Based on the dynamic model, a computational process is created for simulating the real-time operation mode of the MN.

The SCADA simulation module with a certain frequency or at the request of the dispatcher in graphical or tabular form displays on the monitor the flow parameters in the nodes, warning and alarm signals. The dispatcher analyzes the data and identifies the situation on the MN. Depending on the situation and in accordance with the task of the UTZ, the dispatcher selects various control modes for the MN objects. In the process of performing the training task, various diagnostic messages are generated, which are automatically displayed on the monitor screen. The dispatcher may be given the opportunity to call recommendations on the management of MN, if this is provided for by the condition of setting the training task. All actions of the dispatcher during the implementation of the training task are recorded and monitored. Based on this information, a protocol for the implementation of the training task is formed.
