Specifications

Description

IS215VPROH2B is a Turbine Protection Board manufactured and designed by General Electric as part of the Mark VI Series used in GE Speedtronic gas turbine control systems. The Turbine Protection Board (VPRO) and associated terminal boards (TPRO and TREG) provide an independent emergency overspeed protection system. The protection system consists of triple redundant VPRO boards in a module separate from the turbine control system, controlling the trip solenoids through TREG.

Applications

Thermal power plants: Integrated into the turbine control system, executing overspeed trip protection and emergency trip logic for low vacuum, etc.

Natural gas peak-shaving plants: Monitor core operating parameters in gas turbine units, ensuring protection actions are triggered within seconds under abnormal conditions.

Oil refineries: Responsible for monitoring the speed of large industrial turbine drive equipment, achieving multi-level interlocking control through 6 outputs.

Nuclear power plant supporting systems: Applied to the protection circuit of auxiliary turbine machinery, utilizing a 125V DC system to maintain critical safety functions.

Large fertilizer plants: Operate in ammonia synthesis compressor units, ensuring reliable shutdown of high-speed rotating equipment in environments ranging from -30°C to 65°C.

INSTALLATION

Turn off the VME processor I/O rack.

After positioning the edge connectors with your hands, slide the VPRO board into place.

Tighten the front panel's top and bottom captive screws.

Turn on the VME rack and examine the front panel's top diagnostic lights.

OPERATION

The protection module provides turbine emergency overspeed (EOS) protection using three VPRO boards. It also includes backup synchronization check protection, three analog current inputs, and nine thermocouple inputs for gas turbine exhaust over-temperature monitoring. The system is triple redundant with three independent boards (R8, S8, T8), allowing any one to be powered down and replaced during operation without affecting protection. Each board has its own I/O controller. Communications enable test commands from the controller and monitoring of EOS diagnostics on the operator interface. The VPRO board is the system core and includes a VME interface for programming and testing, while the backplane is neutralized in the protection module to maintain full independence between sections.
