3BHE009681R0101 GVC750BE101 exciter control module is a key component in the generator set, its main role is to control the electromagnetic excitation system, and then control the current of the electromagnetic coil, so as to adjust the voltage and current output value of the generator. Specifically, the excitation controller controls and adjusts the current of the excitation winding to keep the magnetic field of the generator set in a constant size and stable state. When the load changes, the excitation controller will automatically adjust the size and parameters of the excitation current to adjust the output voltage and current of the generator and maintain its stable operation. In addition, if the generator overvoltage, overcurrent and other failures, the excitation controller will immediately send a corresponding signal to notify the monitoring system for processing.
In terms of function implementation, the 3BHE009681R0101 GVC750BE101 excitation controller first collects the analog signal in the power system into the control chip to analyze and calculate the current working condition. Then the calculated excitation control signal is input to the excitation power module. The excitation power module controls the excitation current according to the input control signal, and then controls the operation mode of the generator.
Structurally, the 3BHE009681R0101 GVC750BE101 excitation controller usually includes a measurement comparison unit and a comprehensive amplification unit. The measurement and comparison unit is responsible for measuring the generator voltage signal, converting it into a DC voltage signal proportionally, and comparing it with the given DC voltage, sending the motor voltage deviation signal. The comprehensive amplification unit is composed of a comprehensive amplification link, a proportional integration link and an adapter link, which is responsible for comprehensively amplifying various DC signals of basic measurement output, feedback and auxiliary limit generation, as well as stabilization and compensation reactions, and output to the subsequent link for further processing.
