23、synchronous rotating electrical machines. 2 General 2.1 Excitation system The equipment providing the field current of a machine, including all regulating and control elements, as well as field discharge or suppression equipment and protective devices. 2.2 Exciter The source of the electrical power
24、providing the field current of the synchronous machine. NOTEExamples of the source are: a rotating machine, either d.c. or a.c. with associated rectifiers; one or several transformers with associated rectifiers. 2.3 Excitation control The control modifying the excitation power, responding to signals
25、 characteristic of the state of the system encompassing the synchronous machine, its exciter, and the network to which it is connected. NOTESynchronous machine voltage is predominantly the controlled quantity. 2.4 Field winding terminals The place of input to the field winding of the machine. NOTE 1
26、If there are brushes and slip-rings, these are considered to be part of the field winding. NOTE 2In a brushless machine the connecting points between the rotating rectifier and the leads of the machine field winding are the field winding terminals. 2.5 Excitation system output terminals The place of
27、 output from the equipment comprising the excitation system. These terminals may be different from the field winding terminals. 2.6 Rated field current lfN The direct current in the field winding of the machine when operating at rated voltage, current, power-factor and speed. 2.7 Rated field voltage
28、 UfN The direct voltage at the field winding terminals of the machine required to produce rated field current with the field winding at the temperature resulting from rated loading and rated conditions and with the primary coolant at its maximum temperature. NOTEIf the machine has a duty cycle which
29、 does not result in a steady field winding temperature being reached then UfN is based upon the maximum field winding temperature reached in the duty cycle. 2.8 No-load field current lfo The direct current in the field winding of the machine required to produce rated voltage at no-load and rated spe
30、ed (see Figure 1). 2.9 No-load field voltage Ufo The direct voltage at the field winding terminals of the machine required to produce the no-load field current with the field winding at 25 C. 2.10 Air-gap field current lfg The current in the field winding of the synchronous machine which theoretical
31、ly would be required to produce rated voltage at no-load on the air-gap line (see Figure 1). NOTEThe air-gap field current is the base value for use in computer representation models of excitation systems. 2.11 Air-gap field voltage Ufg The direct voltage at the field winding terminals of the synchr
32、onous machine which is required to produce the air-gap field current when the field winding resistance is equal to UfN/lfN. NOTEThe air-gap field voltage is the base value for use in computer representation models of excitation systems. 2.12 Excitation system rated current lEN The direct current at
33、the excitation system output terminals which the excitation system can supply under defined conditions of operation, taking into account the most demanding excitation requirements of the machine (generally resulting from machine voltage and frequency variations). 2.13 Excitation system rated voltage
34、 UEN The direct voltage at the excitation system output terminals which the excitation system can provide when delivering excitation system rated current, under defined conditions of operation. This voltage is at least that value required by the field of the machine under the most demanding excitati
35、on requirements (generally resulting from machine voltage and frequency variations). 2.14 Excitation system ceiling current lp The maximum direct current which the excitation system is able to supply from its terminals for a specified time. 2.15 Excitation system ceiling voltage Up The maximum direc
36、t voltage which the excitation system is able to provide from its terminals under defined conditions. NOTE 1For excitation systems whose supply depends on the machine voltage and (if applicable) current, the nature of the power system disturbance and specific design parameters of the excitation syst
37、em and the synchronous machine influence the excitation system output. For such systems, the ceiling voltage is determined considering an appropriate voltage drop and (if applicable) current increase. BS EN 60034-16-1:1992 4 BSI 04-1999 NOTE 2For excitation systems employing a rotating exciter, the
38、ceiling voltage is defined at rated speed. 2.16 Excitation system no-load ceiling voltage Upo The maximum direct voltage which the excitation system is able to provide from its terminals when it is not loaded. 2.17 Excitation system on-load ceiling voltage UpL The maximum direct voltage which the ex
39、citation system is able to provide at its terminals when supplying excitation system ceiling current. 2.18 Excitation system nominal response VE The rate of increase of the excitation system output voltage determined from the excitation system voltage response curve, divided by the rated field volta
40、ge (see Figure 2). This rate, if maintained constant, would develop the same voltage-time area as obtained from the actual curve over the first half-second interval (or different time interval, if specified). NOTE 1The excitation system nominal response is defined with the excitation system loaded w
41、ith a resistance equal to UfN/lfn and sufficient inductance so that voltage drop effects and current and voltage waveform are reasonably accounted for. NOTE 2The excitation system nominal response is defined with the excitation system voltage initially equal to the rated field voltage of the synchro
42、nous machine, after which the excitation system ceiling voltage is rapidly attained by introducing a specified voltage error step. NOTE 3For excitation systems whose supply depends on the synchronous machine voltage and (if applicable) current, the nature of the power system disturbance and specific
43、 design parameters of the excitation system and the synchronous machine influence the excitation system output. For such systems, the excitation system nominal response is defined taking into consideration an appropriate voltage drop and (if applicable) current increase. NOTE 4For excitation systems
44、 employing a rotating exciter, the excitation system nominal response is defined at rated speed. 3 Exciter categories 3.1 Rotating exciter A rotating machine which takes mechanical power from a shaft. This shaft may be driven by the synchronous machine or by another machine. 3.1.1 D.C. exciter A rot
45、ating exciter employing a commutator and brushes to deliver direct current. 3.1.2 A.C. exciter A rotating exciter employing rectifiers to deliver direct current. The rectifiers may be controlled or non-controlled. 3.1.2.1 A.C. exciter with stationary rectifiers An a.c. exciter with rectifiers whose
46、output is connected to the brushes of the slip-rings of the field winding of the synchronous machine. 3.1.2.2 A.C. exciter with rotating rectifiers (brushless exciter) An a.c. exciter with rectifiers, which rotate with the common shaft of the exciter and the synchronous machine, whose output is conn
47、ected without slip-rings or brushes directly to the field winding of the synchronous machine. 3.2 Static exciter An exciter which derives its power from one or more stationary electrical sources, employing stationary rectifiers to deliver direct current. 3.2.1 Potential source static exciter A stati
48、c exciter which derives its power only from a potential source (which can be the terminals of the synchronous machine) and employs controlled rectifiers. 3.2.2 Compound source static exciter A static exciter which derives its power from both current and potential sources (dependent upon synchronous
49、machine terminal quantities). The addition of inputs from both sources can be done on either the a.c. side or the d.c. side of the rectifiers and can be done in parallel or series. The rectifiers may be either controlled or non-controlled depending upon design. 4 Control functions 4.1 Voltage regulator The equipment comparing the actual voltage of a synchronous machine with a reference value and controlling by appropriate means the output of an exciter, depending on the deviations. 4.2 Load current compensator A device or function influencing the v
