PPD517A3011 3BHE041576R3011 Excitation central executive controller is one of the core control equipment of water turbine generator set, PPD517A3011 3BHE041576R3011 main function is to control the electromagnetic excitation system in the generator set, adjust the voltage and current output value of the generator set. PPD517A3011 3BHE041576R3011 By controlling and adjusting the current of the excitation winding, the magnetic field of the generator set is kept in a constant size and stable state. When the load changes, the excitation central executive 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 has overvoltage, overcurrent and other faults, the PPD517A3011 3BHE041576R3011 excitation central executive controller will immediately send a corresponding signal to notify the monitoring system for processing.
The working principle of PP D517A excitation central executive controller mainly includes three parts: sensor, controller and excitation system. Sensors are used to detect the output voltage and current of the generator, convert the voltage and current signals into electrical signals, and send them to the controller. After receiving these signals, the controller calculates the required excitation current according to the preset parameters and the set control strategy.
The PP D517A controller sends the calculated excitation current signal to the excitation system. Excitation system is composed of excitation transformer and excitation power supply, which is used to convert low voltage signal into high voltage signal and supply it to excitation power supply. The excitation power supply converts the high voltage signal into direct current and supplies it to the excitation coil of the generator to produce a constant magnetic field.
