Description

In USL (DSh1e guides received a wide range of current systems), the current systems of synchronous generators were supplied by kiaiiaiipojjaiiiai. Being simple and hopeful in jiiiiiii. THEY satisfy a number of requirements imposed by exploitation of autolgated rattoram.excited. However, OfHH does not discolour satisfactory. regulation of air in normal conditions and does not give sufficient ()) 0p; emergency and nosdeavariynyh reashmah. This is a nonsignal-1T, ip measure taken from the first and the first-to-first lines connected to the remote power of the lamia; the most common is an abnormal non-distributable 1M of power in the system.

In pddlatasm rep rap tor these disadvantages of Ustradgeia.

This regulation is: a non-negative value for synchronous controllers, for which the internal current of the current transformer used in the generator in the neinf is used for the use of the sound source. Replica H-mevt is an electronic Measuring Body, to the input of which is fed to more than one transformer nanometer. In such a regulator, one nz of two chokes saturates n, used as regulator elements of the regulator, the non-current winding is turned on, 7 SOUND 1) eosta is used for charging, and the other is connected in parallel with the secondary winding trans (| ) 0) current math.- Winding: -: magnetic: 1 both

throttles are fed from the output of the meter of the 1st Organ, consisting of a small bridge, with an electronic device.

Such a regularization system satisfies all the requirements presented. In addition, Ji automatic p & tulators of excitation is as much as the best of modern electronically controlled regulators. With THIS.M, the pre-specified control system has a number of iipeirMyHi; ecTii, such as: 1) the need for control in such a way that, when you exit, the control elements in the workflow remain normal, the compaud is in the rel; private forcing; therefore, there is no need to install additional protective devices; 2) the main power supply sources are current transformers and, therefore, the messenger system is nitapy for emergency operation; 3) the equipment of the retrofitted system consists of the HIWCTBIX and case elements. This one was better, more reliable than a diner. existing automatic controllers tiov excited.

The foregoing is illustrated in FIG. 1 of which is shown, the electric power meter. The diagram of the gagm regulator, and in FIG. 2 - diagram of the measuring body.

Scheme komnaundrovrov.n on fng. 1 differs from the usual nurl. Current system by the fact that instead of the installation resistor it is switched on, the winding of irreversible current of saturation voltage drops and the circuit 227 is inserted into the circuit of the Rush resistor Rsh.

Equal to the extent of nodshztka. The 06 points of the dummies of the saturation dummies are connected to the output of the measuring organ. The scheme is yes in single phase, but it is different, it can be two-phase three-phase.

Pmeritelpyn organ isdsdstall. This combines a non-linear measuring bridge with a two-lamp amplifier.

The element of the measuring bridge. - 1 buttube power from the voltage transformer YOU generator G.

The voltage of the generator increases at the input of the measuring unit, increases in voltage of the lamp 1, the resistance of the lamp decreases; at the same time, the negative bias applied from the bridge diapod to the grids of the amplifying lamps 2 is reduced. The latter begin to iron the anode current and a voltage appears at the output of the gel organ.

Thus, the PDR voltage generator voltage of a certain well-cleaned condition occurs in Kenya at its output terminals.

Coefficient of transformative rectifying transformer. BT, from the CT current transformer, is taken such that, when there is a suction, the current in the choke, TO, VY1ICHINI K01 mnau1vd11rugo, the current is significantly more than 9t: it is necessary for us to control the current voltage. In normal modes, the well of the comparing current is equal to that required for the generator to be equipped with a generator at a given level. The excess part of the current from the current transformers OtsasmnRts choke is consistent with the pressure of the suction TO.

hnchenio papr zhapp above the reference level leads to an increase in the intensity of the spawn of the orgap, to an increase in the current of the jumpers, sppl; with a neck of the inductive sonrogly suction of the suction before n to the suction current. This is a compressed current, excitation, and the generator is reduced to the required values.

As the generator decreases, the generator node current decreases, the inductive current decreases, the inductive resistance of the TO, the compounding current, and the excitation of the neurotransmitter grow.

In order to regulate the nanowire in the Kllm of idling the generator and compensate for the effect of the exciter hysteresis, a negative power supply is provided to the I1-unit resistor Rm of the circulating circuit.

Motv arousal exciter B. Tok. nodnnt1khn Coincides with current t ko1Sh exciter. Increasing the current of the power supply leads to an increase in the additional voltage drop in the circuit caused by it, which is equivalent to the introduction of the resistance of the shunt regimen, that is, of the shunt resistor. The current of the piping is obtained from the generator transformer of the generator. It is corrected by D1) an ossel and a power supply circuit, the winding of which is iodized, which is acquired from the measuring instrument of the organ. RL: for example, a geyrator enme above a predetermined level of tokp podmaglshpvap; n in the inductor iodiitsts, u and the charge current increase, inductance) drossel decrease, generator excitation, decrease-s.

When removed, a generator current is fed to the generator. umepsha: it i excitement itHiepaTopa grow & t. In avarnshy rea; impkh with large nasadkamp papr-keni; Signature throttles of saturation iodpptki chains and suction reached ;; This is the maximum of the X and the generator and excitably grows sharply.

The installation of a change in a given level of the structure, according to the controller, is carried out by means of an installation resistor, in which the part of the device, which is connected to the measured voltage from the voltage transformer, is absorbed.

The stability of the system is regulated; the introduction of flexible feedback (FNG. 2). The steady state is distributed reactively motivated by one person, in the case of their work directly. On the cables, it is achieved by introducing the usual standard stabilization system.

PREMIUM CONDITIONAL STANDARD V15 Automatic voltage regulator for equipped with synchronous generators with an electrical measuring device, the input of which is given to the secondary radio; n with transform current atorOM, rectified; whose current is used. For a company, about 10 meters due to the fact that one of the d.1-} ya chokes are saturated and used in the quality of controlled regulator elements, the overcurrent winding is included in the value of the unit cable of the Shntovy resistor T1) .day , and on the other side, a parallel current secondary winding of a current transformer, a winding of chokes of chokes, feeds the chokes: from the output of the measuring element, which consists of a fuzzy bridge, with an effective bridge.
