IS215VPROH1B Turbine protection plate

IS215VPROH1B Turbine protection plate

The GE IS215VPROH1B is a turbine protection panel from General Electric (GE) designed specifically for Mark VI systems. This protective panel provides an independent emergency overspeed protection system to ensure the safe operation of the turbine.

Its main functions include:

Emergency overspeed protection: The IS215VPROH1B is a key component of the turbine that provides a standalone emergency overspeed protection system. When the turbine speed exceeds the preset safety limit, the protective plate can respond quickly by controlling the trip solenoid valve to trip the turbine, thereby avoiding possible damage or accidents.
Multi-redundancy design: The protection system consists of three redundant VPRO boards, which ensures high reliability and fault tolerance of the system. Even if one of the VPRO boards fails, the other two boards continue to work, ensuring the normal operation of the protection system.
Independent module: The VPRO board is located in a separate module from the turbine control system. This design allows the protection system to work independently of the control system, thereby reducing the risk of protection failure due to control system failure.
Ethernet connectivity: The IS215VPROH1B also has Ethernet connectivity for IONet communication with the control module. This enables the protection system to exchange data with the control system in real time, improving the response speed and accuracy of the system.
Control trip solenoid valve: Through the TREG board, the IS215VPROH1B can control the trip solenoid valve. When the protection system detects that the turbine is speeding, it sends a signal to the TREG board to control the action of the trip solenoid valve, which causes the turbine to trip.
Overall, the GE IS215VPROH1B is a powerful and reliable turbine protection board that ensures the safe operation of the turbine by providing an independent emergency overspeed protection system and multi-redundancy design.
