Product Description

The IS215ACLEH1BB is an enhanced main control board for the GE EX2100 excitation system and is compatible with the Mark VI unit control system. It is responsible for AVR voltage regulation of the generator, PSS stability control, excitation logic protection operations, and is also the core of system communication and self-diagnosis. The module supports the TMR triple redundancy architecture, featuring strong real-time performance and outstanding anti-interference ability, and is compatible with the excitation cabinets of synchronous generators in thermal power, gas turbines, hydropower, etc

Functions

1. Main operation of excitation regulation

Collect the voltage, current, reactive power and speed signals of the generator, execute the AVR automatic voltage regulation, reactive power adjustment and PSS power system stabilizer algorithm, output to control the thyristor rectifier bridge, and control the excitation current of the generator.

2. Logic sequential control and protection judgment

Execute the excitation start-up, demagnetization, excitation start, and shutdown processes. Determine excitation overcurrent, demagnetization, overvoltage, pulse faults, etc., and trigger protection and alarm.

3. System communication hub

Dual Ethernet + dual serial ports. Through ISBus, Ethernet and backplane bus, it connects to the excitation I/O board, HMI, unit DCS, Mark VI gas turbine controller, and uploads parameters and receives instructions.

4. On-board self-diagnosis: Real-time monitoring of CPU, memory, power supply, communication link, and firmware status. The panel LED indicates operation/failure. When a fault occurs, it reports the fault code and supports local debugging.

5 Parameter storage and operation

Save excitation setting values, curves, and setting parameters, perform real-time closed-loop calculation, and support simplex single set and TMR triple redundant architecture configuration

Typical application scenarios

Generator EX2100 excitation control system for thermal power and gas combined cycle power stations (the most mainstream)
Excitation regulation of synchronous generators for hydropower, nuclear power and self-owned power plants
Large industrial synchronous motors (high-power synchronous motors for steel mills, chemical plants and cement plants)
Excitation cabinet matching GE Mark VI Speedtronic gas turbine control system Integrated control of gas turbine and generator for excitation
Control of high-power synchronous generator sets for ships

Important Notes

1. The firmware version with matching: must and a complete set of EX2100 back (IS200ESBP/IS200ERBP/IS200ERRB, etc.), the other I/O interface card firmware version form a complete set of strict; Version mismatch may cause communication abnormalities and excitation loss of control.

2. Priority for static protection: IS215ACLEH1BB is a precision CPU board. During disassembly and assembly, wear an anti-static wristband and do not touch the gold fingers with bare hands. Power-off plug and unplug. For non-redundant configurations, it is strictly prohibited to unplug the board while it is powered on.

3. Environmental control: Control the temperature of the cabinet, prevent dust and dehumidification, and avoid condensation and corrosive gases. Long-term high temperatures will accelerate the aging of on-board capacitors and cause random faults.

4. Parameter backup: Before replacing the module, be sure to export the excitation setting value, PSS parameters, and logic program. The new board requires the installation of programs and calibration, and cannot be directly powered on and put into operation.

5. Spare parts should be distinguished by model: due to differences in suffixes (H1BB/H1B/H1A), hardware and firmware are not interchangeable. Do not mix them. IS215ACLEH1BB is a dedicated ACLE board for excitation, not a general-purpose PLC CPU

6. Pre-operation test: After replacement, no-load, load, PSS and protection drive tests of excitation should be conducted to confirm that the regulation characteristics and protection actions are correct before grid connection.

7. Power supply requirements: Power supply must strictly follow the EX2100 cabinet specifications. Excessive ripple of the DC power supply and voltage drops can cause module reset and excitation disturbance
