• 　describe
• 　　UFC921A101 is the most widely used UNITROL 5000 excitation system.Take my company as an example:
• 　　Switzerland ABB product,type:UNITROL 5000,self shunt static excitation system
• 　　The generator static excitation system controls the excitation current through the silicon controlled rectifier bridge to regulate the synchronous generator voltage and reactive power.
• 　　UFC921A101 is mainly divided into four parts:
• 　　1.Excitation transformer;
• 　　2.Excitation regulator(AVR);
• 　　3.Silicon controlled rectifier;
• 　　4.Excitation and de excitation equipment.
• 　　Excitation transformer
• 　　The excitation transformers are three single-phase epoxy cast dry-type transformers produced by Guangdong Shunte Electric Co.,Ltd;The total capacity is 3X3300KVA;The transformation ratio is 27kV/1060V.
• 　　Natural air cooling(with cooling fan)is selected.When the temperature of excitation transformer reaches 100℃,the cooling fan starts automatically;When the temperature drops to 80℃,the electric fan will automatically stop.When the temperature of excitation transformer reaches 130℃,an overtemperature alarm will be given.
• 　　Three sets of bushing CT shall be supplied for each phase on the HV side,two for maintenance and one for measurement.Each phase of the low-voltage side is also equipped with three sets of CT,two for maintenance and one for measurement.
• 　　Automatic voltage regulator AVR
• 　　The primary function of automatic voltage regulator(AVR)is to precisely control and regulate the voltage and reactive power at the generator terminal.It can quickly respond to the excitation voltage with a response time of several milliseconds.
• 　　AVR selects dual channel system with manual emergency standby channel,which is the highest configuration of excitation system of UNITROL 5000 system at present.
• 　　Fundamentals of AVR
• 　　It is mainly composed of three basic units:measurement comparison,inductive expansion and phase shifting trigger.
• 　　The measurement comparison unit is used to measure the converted DC voltage proportional to the generator terminal voltage,and compare it with the corresponding voltage setting value to obtain the error;
• 　　The voltage error signal is input into the inductive expansion unit,and the inductive expansion unit plays an inductive expansion role in measuring signals;
• 　　The phase-shifting trigger unit changes the trigger pulse and conduction angle output to the silicon controlled rectifier according to the change of the input control signal,and then controls the output voltage of the silicon controlled rectifier and regulates the excitation current of the generator.
• 　　Overview:If you need urgent delivery orders,please feel free to contact us,and we will try our best to meet your needs.
• 　　Price problem:If you find that other suppliers supply cheaper prices for the same product,we are also willing to provide you with reference prices and give you further discounts.
