On my last post,i already discuss about excitation system for generator.I explain generally about basic operation and application for excitation system. For more detail about this topic,i want share some information about several types of excitation system that commonly used for generator. I hope with it can bring up some guide line and basic knowledge [...]
What is the excitation?The main purpose of excitation system for generator is to supply the power source to the rotor field coil.Excitation system produce the field current and it controlled by the automatic voltage regulator (AVR).I already discuss about automatic voltage regulator on my last post. This field current controller is important to ensure the [...]
Generator is the important power supply equipment to generated electricity.Without electricity,we cannot operated machinery,equipment,lighting,computer and others device for our living. For general power supply,power distributor normally used the high capacity of generator to supply the electricity to the consumer.It different size for backup power supply that used for hospital,server room,critical equipment or important area. I [...]
Basically automatic voltage regulator for generator have a 2 mode selection.It is with full automatic function and manual function. I already discuss about AVR function and basic operation in my last post.Please refer to basic of automatic voltage regulator.i hope it can make a clear view and understanding about AVR function in generator. This time [...]
Basically the AVR or Automatic Voltage Regulators function for generator is to ensure voltage generated from power generator running smooth to maintain the stable voltage in specified limit. It can stabilize the voltage value when suddenly change of load for power supply demand. If the generator running in parallel condition,the AVR can controlled the voltage [...]
The AVR ( automatic voltage regulator ) is suitable for supplying power to the fields of either brushless or commutator type exciters and will maintain the A.C generator voltage within plus and minus 1% of the preset value with paralleling. When the load varies between no load and rated load and with a frequency changes [...]
For a given excitation,if speed of an A.C. generator is reduced then the output voltage would reduce also.In practice,this reduction in output voltage is sensed by the AVR ( Automatic voltage regulator ) which increases the excitation current to compensate. However,the field forcing capabilities of the AVR which are necessary to maintain output voltage during [...]
