Steam Turbine Controls

HPI’s turbine specialists know the unique steam turbine control requirements for improving turbine performance and reliability by upgrading key components, such as extraction valves, hydraulic safety blocks, and main steam valves. For older model steam turbines, HPI can provide upgraded diagnostic capabilities by adding field devices at critical points in the steam cycle to reduce the cost of unscheduled outages and repairs. HPI’s custom steam turbine control solutions can integrate with other systems and instrumentation to facilitate communication with SCADA or DCS.

The HPI steam turbine control solutions leverage commercially off-the-shelf (COTS) PLC controls and open-architecture software. These systems are safe and cost effective, providing a flexible solution to any application.

Steam Turbine Control: Cost Competitive Alternative
HPI specializes in providing cost-effective steam turbine control solutions for smaller steam turbines (<200 MW).  HPI can offer relatively low cost upgrades for control retrofits and a full range of mechanical services. However, HPI’s staff has performed successfully on steam turbines up to 750 MW.

Improved Steam Turbine Controls for Older Models
HPI can increase the diagnostic capability of older model steam turbines by installing additional field devices at critical points in the steam cycle and integrating them to the new control system. The performance of the turbine can be further enhanced by upgrading key components such as extraction valves, hydraulic safety blocks, and main steam valves.

HPI steam turbine controls can be configured to run diagnostic programs for detecting and predicting issues in order to more effectively plan maintenance. With the integration of preventative diagnostic programs and low-cycle fatigue calculations, on-demand or frequency reports can be generated for engineering and maintenance personnel. These can reduce the cost of unscheduled outages and repairs, and offers both savings and convenience.
