Core functions and technical architecture

3.1 IS215AEPAH1CH: High performance real-time control engine

IS215AEPAH1CH is a reinforced application processor module based on QNX RTOS, which communicates with I/O modules through VME or dedicated backplane bus. The system loads control logic (functional block diagram, ladder diagram, or sequential functional diagram) from flash memory and executes all control algorithms within a determined frame rate cycle, including automatic voltage regulation (AVR), fuel valve servo control, temperature closed-loop, speed regulation, and generator excitation management.

This module communicates with the I/O module through IONet - a dedicated 100 Mbps full duplex Ethernet network that provides deterministic, low latency data exchange. IONet adopts the IEEE 1588 precision time protocol to achieve microsecond level time synchronization, supporting SOE (Sequential Event Recording) resolution of ± 1 ms. In dual or triple redundant configurations, multiple AEPAH1CH modules run in parallel and achieve interference free switching through a 2/3 voting mechanism: when one module fails, the remaining modules continue to control to avoid production interruption.

3.2 IS210BPPBH2CAA: High reliability power and signal interconnection platform

The core value of BPPBH2CAA lies in building a low-noise, high availability electrical foundation for the entire Mark VIe control architecture. The backplane adopts multi-layer impedance control PCB to ensure the integrity of high-speed serial signals and effectively suppress electromagnetic interference generated by devices such as frequency converters and high-power switches. Each I/O slot is equipped with an independent power filtering network and transient suppression circuit to prevent surge conduction from the field side to the controller side.

The module hot plug function allows maintenance personnel to directly replace faulty I/O modules during system operation: BPPBH2CAA will automatically cut off the power supply to the corresponding slot and notify the controller module that it has been removed through in place detection signals; After inserting a new module, the power supply automatically recovers and the controller automatically completes the reconfiguration. This design significantly reduces the mean time to repair (MTTR) and improves the availability of continuously operating equipment such as gas turbines.

3.3 Redundancy and Fault Tolerant System

Mark VIe provides multi-level redundancy options to meet the requirements of different process criticality:

Power redundancy: supports dual 24 V DC inputs, can achieve automatic hot standby switching

Controller redundancy: AEPAH1CH can be configured as duplex or triple redundancy (TMR)

I/O network redundancy: IONet supports dual or triple independent networks

I/O module redundancy: Each I/O point can be configured as a single, dual, or triple sensor input

In a triple redundant system, three AEPAH1CH modules run the same application program and exchange voting data through the BPPBH2CAA backplane. When a module outputs abnormally, the output voting results of the other two modules are adopted, and the faulty module is isolated and reported to the maintenance system.

Application Fields

This core combination is widely used in GE gas turbine, steam turbine, and compressor control:

7FA, 9FA, 6FA, 6B, and H-class combustion engines: fuel valve control, combustion chamber temperature regulation, ignition sequence, and overspeed protection

Steam turbine: inlet valve position management, bypass system, extraction regulation, and vibration monitoring

Compressor anti surge protection: load distribution and surge boundary control

Generator excitation system (EX2100e): shares IONet with AEPAH1CH to achieve excitation current regulation and reactive power management
