DS200QTBAG1ADC Excitation controller

GE DS200QTBAG1ADC is a kind of excitation controller, which is the core control equipment of water turbine generator set.

The main function of the excitation controller is to control the size and stability of the generator excitation current, so as to control the size and fluctuation of the output voltage and current, and ensure that the generator set can run stably in various working states. Specifically, the excitation controller controls and regulates 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.

The application field of GE DS200QTBAG1ADC is mainly concentrated in the excitation control system of hydropower turbine generator set. As an excitation controller, it plays a vital role in hydropower station. Specifically, it is responsible for controlling and regulating the excitation current of the hydrogenerator set to ensure the stable operation of the generator set and the stability and quality of the output voltage and current. By precisely controlling the excitation current, the GE DS200QTBAG1ADC optimizes the performance of the generator set, increases power generation efficiency, and reduces operating costs. In addition, the controller also has powerful fault monitoring and protection functions, which can detect and deal with abnormal conditions during the operation of the generator set in time to ensure the safe and stable operation of the power system.
