General DescriptionThe Vertex Compressor Control is field programmable which allows a single design to be used in manydifferent control applications and reduces both cost and delivery time.

It uses a built in graphical userinterface (GUI) with multi-lingual menu driven screens to instruct site engineers on configuring the controlto a specific compressor application. The Vertex can be configured to operate as a stand-alone unit or inconjunction with a plant's Distributed Control System.

The Vertex control has 12 PID controllers that can affect the controlled operation of the compressor.

1. Anti-Surge PID Stage 1

2. Suction Pressure Override Stage 1

3. Discharge Pressure Override Stage 1

4. Rate Control PID Stage 1

5. Anti-Surge PID Stage 2

6. Suction Pressure Override Stage 2

7. Discharge Pressure Override Stage 2

8. Rate Control PID Stage 2

9. Performance Control PID

10. Performance Limiter 1 PID

11. Performance Limiter 2 PID

12. Load Sharing PID

Depending on the configuration of the Vertex, these PIDs may be used or not used. Please refer to theBlock diagrams listed later in this chapter to fully understand PID relationships.

Anti-Surge Control

The Vertex can be applied to protect one or two section compressor trains from surge.

The control isconfigured with the OEM provided compressor performance map which describes the Surge Limit Line.

ASurge Control Line with a configured margin away from the Surge Limit Line is generated.

The controllercontinuously monitors the current operating point of the compressor and compares it with the SurgeControl Line to determine if opening of the Anti-surge valve is necessary.

The Vertex control protectsagainst surge by modulating one or two Anti-Surge Valves (or blow-off valve) while keeping processconditions within acceptable limits.

Performance Control

The Vertex has a Performance Controller (PFC) which is commonly configured to drive suction/dischargethrottle valves, Inlet Guide Vane position, or speed control setpoint.

When configured, this control functionis used to control compressor suction pressure, compressor discharge pressure, compressor flow, or anyprocess variable related to compressor flow or load.

This control function compares an analog inputsignal to an internal setpoint and, depending on the programmed configuration, positions the compressorthrottle valve, inlet guide vanes, torque converter, and/or motor speed (VFD) to accomplish the desiredcontrol.
