Definitions
- the purpose of the present invention patent is to present a new de-excitation system for synchronous machines with indirect excitation by means of rotating diodes, which would improve the dynamic response and safety at the time of de-exciting the machine, which implies that in case of internal short circuit the damages in the machine would be much smaller.
- the brushes and the rubbing rings are elements with maintenance, especially in machines of great power.
- the brushes wear out with use and must be replaced and maintained. Sparks and carbon deposits are also always a focus of possible problems. So in synchronous machines, excitation mechanisms of the brushless inductor tend to be used.
- the system object of the present invention allows a synchronous indirect excitation machine to behave, for the purpose of de-excitation, in a similar way to what a direct excitation machine would do, but maintaining the advantages of brushless excitation.
- de-excitation impedance preferably a resistance, connected between the inductor winding of the synchronous machine and the rotating rectifier bridge;
- a maneuvering element preferably of the semiconductor type, connected in parallel with the de-excitation impedance
- control circuit of the operating element configured to: • in normal operation of the synchronous machine, keep the operating element closed so that the rectifier bridge Rotary directly feeds the inductor winding of the synchronous machine;
- the control circuit is preferably configured to open the operating element depending on the voltage at the exit of the rotating rectifier bridge, so that when acting on the inductor winding of the exciter, the voltage at the output of the rectifier bridge can be controlled rotating and therefore the de-excitation of the synchronous machine.
- a voltage divider in parallel with the rotating rectifier bridge and consisting of a first and second auxiliary resistors, said voltage divider being configured to open the maneuvering element when the voltage on the second resistance reaches a certain value.
- the control circuit may additionally comprise a zener diode in parallel with the second resistor in order to limit the voltage at the control input of the operating element.
- FIG. 1 shows a scheme of the rapid de-excitation system for synchronous machines with indirect excitation, object of the present invention patent.
- FIG. 2 shows a preferred embodiment of the rapid de-excitation system for synchronous machines with indirect excitation, object of the present invention patent.
- FIG. 3 shows the results of the simulation of a short circuit in bums of a 2MVA synchronous machine with conventional indirect excitation.
- FIG. 4 shows the results of the simulation of a short circuit in bums of the same synchronous machine of 2MVA above on which the de-excitation system object of this invention has been included.
- Figure 1 shows a scheme of the de-excitation method object of this invention, where the following references are used: - Synchronous machine 1.
- FIG. 2 shows a scheme of the preferred embodiment, where additionally the following references are used:
- the rapid de-excitation system for synchronous machines with indirect excitation comprises, at least, a set of rotating components connected between the rotating rectifier bridge 8 and the inductor winding 5 of the main synchronous machine 1.
- Said rotating components comprise, in turn and at least, a de-excitation impedance 10, a maneuvering element 9 and a control circuit 11 of the maneuvering element 9, these elements being in turn connected to the inductor winding 5 of the machine synchronous 1.
- the de-excitation impedance 10 is connected, in series, with the inductor winding 5 and the maneuvering element 9, which is connected in parallel with the de-excitation impedance 10.
- the operating element 9 is closed in such a way that the rectifier bridge Rotary 8 feeds the inductor winding 5 of the synchronous machine 1, just as it would in a conventional synchronous machine.
- the control circuit 11 sends an order to open the operating element 9 so that the de-excitation impedance 10 is in series with the inductor winding 5 of the machine synchronously 1 and with the rotating rectifier bridge 8, so that the current in the inductor winding 5 of the synchronous machine 1 tends to extinguish very quickly (see Figure 4), thanks to the de-excitation impedance 10.
- Figure 3 corresponds to the short-circuit current in the case of traditional indirect excitation
- Figure 4 shows the result of implementing the system object of this invention patent to the previous machine, and where it is observed that the duration of the current Short circuit is greatly reduced.
- a semiconductor, transistor will be used as operating element 9
- this semiconductor will be triggered, that is, it conducts, when the voltage at its door or control input is positive and of a certain value.
- a control circuit 11 will be used which comprises, in turn and at least one voltage divider, formed by two auxiliary resistors, a first 12 and a second 13 resistors. So no control element external to the generator rotor is needed.
- the entrance to the semiconductor door will be protected by means of a zener diode (14) or another surge protector.
