IS200EPMCH1GE Mark VIe Patch Cord Power Distribution Card

Product Overview

The IS200EPMCH1 exciter AC feedback board card is typically used in large rotating machinery, such as turbine gas turbines and generator sets. Its main function is to receive the AC feedback signal from the excitation system and convert it into a digital signal suitable for the control system, thereby achieving precise control of the excitation system.

Its role in the turbine gas turbine system

In a turbine gas turbine system, the excitation system is the key to controlling the output voltage and frequency of the generator.

 The IS200EPMCH1 exciter AC feedback board, as an important component of the excitation system, plays the following roles:

Signal acquisition: Collect feedback signals such as AC voltage and current from the excitation system.

Signal conversion: Convert analog AC signals into digital signals to facilitate computer processing.

Signal filtering: The collected signal is filtered to remove noise and improve signal quality.

Signal isolation: Isolate analog signals from digital signals to prevent interference.

Data transmission: The processed digital signal is transmitted to the excitation control system to provide accurate feedback information for the control system.

Working principle

Signal acquisition: The AC voltage and current signals of the excitation system are converted into weak analog signals through sensing elements such as transformers or shunt sensors.

Signal conditioning: Analog signals are processed through amplification, filtering, etc., to make their amplitude and frequency suitable for A/D conversion.

A/D conversion: Analog signals are converted into digital signals.

Digital signal processing: Digital signals undergo further processing, such as correction and compensation, to enhance their accuracy.

Data output: The processed digital signal is transmitted to the excitation control system through the communication interface.

Advantages in turbine gas turbine systems

Improving control accuracy: By providing precise feedback signals, the accuracy of the excitation control system has been enhanced, thereby stabilizing the generator output.

Enhancing system reliability: Measures such as signal isolation and filtering have improved the system's anti-interference ability and enhanced its reliability.

Easy maintenance: Modular design makes it convenient to replace and maintain.

Strong adaptability: It can adapt to various excitation systems and control systems.
