Automated Process Control System (APCS) of Compressor Station (CS)

Application

Automated process control system (APCS) of compressor station (CS) or compressor department (CD) is designed for control and security of basic and additional technological processes, CS and CD working modes of a gas supply system. APCS is a complete hardware and software system that maintains all necessary functions of control and regulation of all processing equipment in CD. For example:

• gas purification unit (GPU);
• air coolers (AC);
• fuel, start-up and pulsed gas treatment unit (FSPGTU);
• gas reducing unit;
• valves in an industrial site and other accessory equipment of CS.

Functions

Basic functions of APCS of compressor station (CS) or compressor department (CD):

1. Control function:

• automatic control or control by the operator’s command of process equipment of the CD;
• load distribution between gas compressor units to achieve energy conversion efficiency of gas turbine engine.

2. Regulating function:

• regulation of CD mode (gas pressure at the CD outlet, gas flow rate, compression rate, gas turbine engine rpm speed in gas compressor units);
• automatic security of CD process equipment at all working modes;
• regulation of maximum gas pressure limit at the CD outlet and minimum gas pressure limit at the CD inlet;
• anti-surge regulation and protection of gas compressor units (GCU).

3. Informative function:

• display of the CD process equipment state;
• archiving of CD technological parameters;
• preparation of reporting documents;
• informative interaction with higher-level systems.

Basic functions of APCS of gas compressor units:

1. Control function:

• automatic control of the conditions for the unit to start;
• automatic control or control upon the operator’s command of the process equipment of the gas compressor unit (GCU);
• automatic shutdown of the unit in case of critical failures of ACS GCU.

2. Regulating function:

• automatic GCU protection during all working modes;
• automatic regulation of technological parameters of the gas turbine engine.

3. Informative function:

• automatic adjustment or adjustment upon the operator’s command of modes (hot reserve, start-up, stop, change of compressor rotor frequency, etc.);
• calculation of technical-and-economic indices of GCU;
• display of GCU process equipment state;
• archiving of GCU technological parameters;
• preparation of reporting documents;
