Description

The General Electric IS215VPROH2B is a high-reliability Turbine Protection Board (VPRO) designed for the Mark VIe Speedtronic control system. This module serves as the critical component in an independent, triple-redundant emergency overspeed protection system. It operates autonomously from the primary turbine control system to ensure fail-safe shutdown capabilities for gas, steam, and hydro turbines.

Features

  • Emergency turbine protection with triple-redundant architecture.
  • Advanced speed monitoring for precise overspeed detection.
  • Integrated synchronization logic for complex turbine control environments.
  • Extensive diagnostic coverage for system health monitoring.
  • Direct interface to trip solenoids via TREG and TRPG terminal boards.

Applications

  • Power Generation Plants: Fail-safe overspeed protection for thermal, nuclear, and hydro turbines.
  • Oil & Gas Refineries: Mechanical drive control for compressors and pumps.
  • Petrochemical Complexes: Steam turbine management in combined-cycle energy recovery systems.
  • Large-Scale Industrial Manufacturing: Power island control for steel and chemical processing.
  • Offshore Rigs: Reliable turbine-driven power and pumping in remote, harsh environments.

Installation Guidelines

  • Ensure the system is powered down before inserting or removing the VPRO module from the VME rack.
  • Connections to terminal boards (e.g., TREG or TPRO) typically utilize 37-pin, D-type industrial cables.
  • For cable runs exceeding 20 feet, the use of shielded twisted-pair wiring is mandatory to mitigate EMI.
  • Shield drain wires must be terminated only at the end adjacent to the terminal boards to prevent ground loops.
  • Maintain adequate ventilation within the cabinet to ensure the module operates within its specified temperature range.

FAQs

What is the IS215VPROH2B?

The GE IS215VPROH2B is an Emergency Turbine Protection Board (VPRO) within the General Electric Mark VIe Speedtronic control system series.

What is the primary function of this board?

It acts as the core of an independent emergency trip system. It monitors turbine speed and provides emergency overspeed protection, operating separately from the primary control system to ensure a fail-safe shutdown.

What power supply does it require?

It operates on a 125 V DC nominal supply. It generates its own internal 5 V DC and 28 V DC for onboard logic and relay operations.

How many trip solenoids can it control?

The system supports up to three trip solenoids. These are connected between TREG and TRPG terminal boards, which the VPRO manages through 12 relays using 2-out-of-3 voting logic.
