Gazprom transgaz Yugorsk was implemented by SAU the compressor center

On July 25, 2016 the Fiord company announced the joint project of automatic management system of compressor workshop with Kaliningradgazpriboravtomatika LLC ("KGPA") (an APCS of CC) with gas-distributing units (HPA) on Punginsky health Facilities MG, KTs-1, by request of Gazprom transgaz Yugorsk LLC.

Project Tasks

APCS of CC represents a distributed object management system of the main and auxiliary technology of CC with separation of functions of control and management between shop and modular levels of management. An APCS of CC performs all necessary functions:

• control of parameters of CC,
• technology protection,
• automatic control of performance of CC,
• load distribution between GPA,
• diagnostics and report generation.

Important component of an APCS of CC is SAU GPA. SAU GPA is intended for the accomplishment of functions of automatic control, control and protection ensuring trouble-free long operation of GPA, ensuring regulation of parameters of the unit and maintenance of the set mode as directly on settings of the shift engineer, and under control of an APCS of CC.

Project Progress

In the project, 7 control cabinets are a part of an APCS of CC:

• cabinet of CC,
• cabinet of the communication equipment,
• junction point cabinet,
• cabinets of USO (2 pieces),
• rack of the server hardware,
• panel of reserve management.

As a part of each SAU GPA:

• power distribution block,
• link unit,
• control block engine,
• control block supercharger,
• control block cranes,
• local USO (3 pieces),
• panel of reserve management.

In a system universal programmable MK-150 Fastwel controllers (fig. 2), the distributed periphery of Fastwel I/O, the protected real-time operating system of Neutrino KPDA.10964-01 and the instrumental Izagraf environment 6 are used. Communication between controllers and the top level is executed on Ethernet/UDP. Communication with USO is Ethernet/UDP and ModbusRTU.

For an automated workplace and servers the MasterSCADA software package is used. The created management system has technical characteristics:

• 800 physical signals of input-output,
• 5 interface channels,
• 7800 variable tags,
• 150 alarm signals,
• 240 trends (the archived analog parameters, the period of 250 ms),
• redundant server (DBMS Firebird),
• 2 AUTOMATED WORKPLACES.

Projecting a system, specialists of "KGPA" developed mezzanine boards of input-output for support of an ecosystem of the distributed periphery of Fastwel I/O in the Izagraf environment 6. The openness of executive system and the Izagraf development environment 6 helped to build in necessary modifications a system core that allowed to reach the required level of high-speed performance – updating of inputs and exits of a line from 64 modules (up to 440 signals) connected on the bus FBUS, for 6 ms, and connected on Ethernet – 50 ms.

In the course of tests of a system at the motor stand with the turbine jet PS-90 the fast technology archive on a controller RAM disk is implemented: archiving up to 16 analog parameters and up to 32 discrete parameters with frequency of cycle PLC (20 ms). The program of archiving interacts with executive system Izagraf via open interfaces of inter-process communication.

Archiving is executed cyclically in the ring buffer of 10‑60 minutes in depth. Preserving on a RAM disk is executed at accident or at the command of the operator. Data from a RAM disk in the CSV format can remain for the subsequent analysis, under the SAMBA, FTP protocol or by means of the removable medium USB.

Project Results

For July 25, 2016 a system works in a continuous duty, all requirements of PJSC Gazprom for an APCS of CC and SAU GPA are implemented. Acceptance tests confirmed high utilization properties of a system. "Neman payment processing center" and SAU GPA "Neman-R" are recommended to an APCS of CC for complex automation of objects of transport of gas.

The project is executed within a year: from bench tests of the Neman-R software and hardware complex in April, 2015 before acceptance tests in April, 2016.
