High reliability: With high anti-interference ability and stability, it can ensure long-term stable operation and reduce failure rate. Easy to maintain: With self diagnostic and fault indication functions, it is convenient for maintenance and troubleshooting. Multiple interfaces: Supports multiple communication interfaces and protocols, facilitating communication and control with other devices.
The PVD164A2059 3BHE014340R2059 excitation controller has various characteristics, including the ability to automatically calculate the required excitation current based on preset parameters and control strategies, achieve fast and accurate adjustment of the generator output voltage and current through feedback mechanisms, and have a protection mechanism to ensure the safe operation of the generator and excitation system. In addition, the excitation controller can also improve the stability and reliability of the power system, reducing the possibility of faults occurring.
The working principle of PVD164A2059 3BHE014340R2059 excitation controller involves three main parts: sensor, controller, and excitation system. The sensor detects the output voltage and current of the generator and converts them into electrical signals to be sent to the controller. The controller calculates the required excitation current based on the preset parameters and set control strategy, and sends it to the excitation system. The excitation system converts the low-voltage signal into direct current through the excitation transformer and excitation power supply based on the signal sent by the controller, and provides it to the excitation coil of the generator. In this way, the excitation coil of the generator can generate a constant magnetic field, thereby regulating the output voltage and current of the generator.
The working principle of PVD164A2059 3BHE014340R2059 excitation controller mainly includes the following aspects:
Excitation device main circuit: It completes two major functions of rectification and demagnetization, and adopts a three-phase fully controlled bridge thyristor rectification circuit to provide DC excitation current to the rotor winding of the synchronous motor.
Deexcitation circuit: composed of thyristors and diodes in reverse parallel, it completes the series connection of starting resistors during asynchronous starting of synchronous motors. After starting, it automatically cuts off to ensure that the rotor excitation winding of synchronous motors is neither open nor short circuited during asynchronous starting.
System control part: including PLC, touch screen, and microcomputer excitation controller. PLC is responsible for logic control, PI adjustment, and external communication. The touch screen is used for system parameter setting and fault information inquiry. The microcomputer excitation controller completes tasks such as frequency measurement, pulse formation, and fault detection.
