2.Functional Features
Generator regulation and control functions:
Four excitation control modes:including automatic voltage regulation(AVR),manual or field current regulation(FCR),power factor(PF)and reactive power(VAR)control.
In AVR and FCR control modes,soft start voltage increase is achieved through adjustable ramps.
Limit overexcitation(OEL)and underexcitation(UEL)in AVR,VAR and PF control modes.
Underfrequency compensation(volts/hertz),line drop compensation and other functions.
Supports parallel connection of generators and actual power load sharing,as well as synchronization of one or two circuit breakers.
Real-time monitoring and alarm:
The module can monitor the operating status of the generator in real time,including parameters such as voltage,current,frequency,and temperature.
Once an abnormal situation is found,the module will immediately alarm to ensure timely measures.
Programmability:
Supports programmable logic control,and users can write and modify control logic according to specific application requirements.
Provides a flexible way to implement automated tasks.
High reliability and easy maintainability:
Use high-quality components and strict production processes to ensure product reliability and stability.
Provides a simple interface and intelligent diagnostic functions to facilitate users to troubleshoot and maintain.
