Selecting a suitable generator for your application- Part 2

Last time,on my post “Selecting a suitable generator for your application – PART 1”,I’m promised to continue discussion about selecting a suitable generator for your application.In this post, I explained details and shared some tips to get a suitable generator for your application.

What’s this THD?

For ensuring smooth and continuous running of generator it is important to measure its THD –total harmonic distortion. When a significant portion of the load on a generator (or any power source for that matter) is non-linear, all the loads fed by the source will see this distortion. read more

Selecting a suitable generator for your application- Part 1

Ever tried to buy a generator? No? Then, you are saved a potential existential crisis, by God’s grace!! Ask someone who has tried to buy and actually landed with one.

And, he or she would tell you about the trials and tribulations involved in the process. It’s like trying to decode the proverbial riddle: horse before the cart or the cart before the horse!

Do you need a standby generator, single-phase, three-phase, kW, KVA, welder, or motor starting generators? Or, do you need a diesel run or a petrol run generator? read more

Types of excitation system

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 about excitation system for generator.I suggest for more detail information and understanding,please contact your local generator supplier.Below are listed types of excitation system for generator :- read more

Generator exitation

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 running in the suitable voltage.It also controlled the value of current when generator connected to a large load.It will receive or delivery the required level for reactive power ( kVAr). read more

Types of generator

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 want share some information about types of generator and basic operation.Generators are generally classified in accordance with speed and construction.We can categories the generator with following types. read more

Controller method for automatic voltage regulator

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 i want share some information about controller method that commonly used for AVR for generator.For latest design of AVR,manufacture put a two(2) selection for AVR controller mode.It is Automatic and Manual mode. read more

Basic of automatic voltage regulator

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 that it produce to ensure of equal value for reactive load sharing.

For the big system of interconnected power distribution with parallel design,it must have a full controlled and transient stability particular must added for requirement to the Automatic Voltage regulator for generator. read more
