2 Excitador Digital Campo del Generador A Núcleo de Control PCM D
EX2000 Feedback Variables and Addressing   1)     Explain the overview drawing, The AC input is the secondary of the PPT, the SCR represents a PCM, the output of the SCR represents the output of the PCM to the generator field, the inputs on the left of the are all the feedback signals going into the EX2000. The box represents the control core of the exciter. Basically the feedback signals go into the control core, the core calculates the correct SCR firing angle and then outputs the firing signal to the PCM. 2)     With the use of mouse clicks the following will appear: a) What is the feedback to the Automatic Voltage regulator? (Generator Terminal Volts) b) What are the other 4 feedback signals? 1) AC Stator Amps 2) DC Field Volts 3) DC Field Amps 4) AC Line volts c) What needs to happen to the signals so that the control core can process the signals? (A to D and D to A) d) Rated Generator terminal volts = _______________ (Fill in the correct amount on the board) e) Equals ________________ counts (At this time explain that counts are units and 20,000 was chosen to represent rated voltage values, then click and 20,000 will appear in the space) f) At variable address VAR. ________________ (Now explain how the counts are stored at an address and what a variable address is, then click and VAR.1150 will appear) g) What would be the digital counts in VAR.1150 if the generator terminal voltage was 90% of rated (18000 counts) Tensión nominal de los terminales del Generador = ___________VAC Igual ___________Cuentas @ Dirección Variable VAR._____________ Cual seria la cuenta digital en VAR.1150 si la tensión del terminal del generador fuese un 90% de la nominal?

Tensión de la Terminal del Generador Amperios del Estator CA A D Núcleo de Control Tensión del Campo de CC Amperios del Campo de CC PCM Tensión de la Línea de CA EX2000 Feedback Variables and Addressing   This slide is similar to the last slide. Mouse clicks will bring up questions and answers. Remember the following: a) Rated AC Stator Amps is the value on the nameplate called ARMATURE AMPS b) DC Field volts is the maximum output of the PCM. That is referred to as having all the Scr’s getting turned on as soon as possible so that they are responding as if they were diodes. That would be called the v. Another name , used in the book as well as Edo is the ceiling voltage of the bridge. In either case the maximum voltage of the PCM is 1.35 X PPT secondary output in RMS. An example would be if the PPT is rated 4160/380 the max output of the bridge is 380 X 1.35 = 513 VDC c) DC field Amps is AFFL which is the nameplate value called FIELD AMPS d) AC line volts is refering to the PPT secondary voltage. This is scaled to the peak voltage. Therefore for a 380VAC secondary counts = X 380VAC = 537VAC peak Amperios nominal del Estator de CA = ___________ Amps CA Igual ___________Cuentas @ Dirección Variable VAR._____________ PPT Secundario
