GE LM2500 and LM Series

GE LM2500 and the LM Series Controls
The GE LM series is one of the most advanced ranges of turbines in the world. The requirements for safe, accurate controls of these turbines are very rigorous. The control system must be capable of very rapid scan times and include critical compressor surge monitoring. The HPI engineers have a detailed knowledge of the GE Installation Design Manual (IDM), and all of the HPI control systems meet or exceed these requirements.

HPI is world leader in the supply of critical control systems of this type. HPI’s knowledge of the LM series dates back to the early 1990’s. HPI provides fully engineered, custom PLC-based control systems for LM1600, LM2500, LM5000, and LM6000 gas turbines. These control solutions include precise automatic governing, sequencing and load control, regardless of industry or application. The HPI control systems have been proven to dramatically increase start availability, reliability, and performance when compared to analog-relay or hydro-mechanical systems. It also has extensive diagnostics and communication facilities allowing for easy interface with other systems, including SCADA or DCS.

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