En el mercado existen algunas versiones como, por ejemplo, el camión Dumper minero T 282 B, de la firma Liebherr, que incorpora un motor diesel principal para accionar un alternador, con objeto de alimentar dos motores de inducción, uno por cada rueda tractora, pero el sistema de frenado es regenerativo disipativo. El calor se disipa en unas resistencias y se precisa energía eléctrica adicional para activar ventiladores que evacuen al exterior el calor producido.Conventional braking systems dissipate energy in the form of heat, return it to the network for use by other electromechanical systems and others, store it in supercapacitors to reinforce the fuel cell.

El funcionamiento del sistema integral de generación y almacenamiento de hidrógeno y oxígeno, procedentes de la energía eléctrica del frenado regenerativo de las máquinas síncronas y máquinas de inducción, de tracción eléctrica, instalado a bordo de un vehículo, en virtud de la figura 2, es el siguiente:The operation of the integral system of generation and storage of hydrogen and oxygen, coming from The electrical energy of the regenerative braking of the machines Synchronous and induction machines, electric traction, installed aboard a vehicle, under figure 2, is the next:

Se parte del sistema generador de energía mecánica que, en este caso, es el motor principal de combustión interna (34). Este motor, mediante un acoplamiento mecánico (35), acciona el alternador trifásico (36). La tensión generada en el alternador (36) es rectificada mediante el puente rectificador totalmente controlado (7), cuya tensión de salida, V_{cc1}, se modifica mediante el sistema de control (6). La tensión V_{cc1} se aplica a la batería de supercondensadores (8) y a través del chopper (15), al electrolizador (17). La salida de la batería de supercondensadores (8) se conecta al bloque de conexión del bus de corriente continua (9). La salida del bloque del bus de corriente continua (9) se conecta a los inversores (10) y (11), los cuales, en función de las señales de control y monitorización del bloque (12), generan sistemas trifásicos independientes de tensiones y frecuencias variables, que se aplican a dos máquinas eléctricas, que pueden ser síncronas o de inducción (13) y (14), estando los ejes de las mismas unidos a los ejes de las ruedas motrices (39) y (40). Estas máquinas síncronas o de inducción (13) y (14) pueden funcionar como motor/generador.Be part of the power generating system mechanical which, in this case, is the main combustion engine internal (34). This engine, through a mechanical coupling (35), actuates the three-phase alternator (36).

These synchronous or induction machines (13) and (14) can work As engine / generator.

La descripción desarrollada hasta ahora es la que corresponde al funcionamiento del sistema cuando realiza una acción motriz, puesto que las máquinas síncronas/de inducción (13) y (14) funcionan en este estado como motores síncronos/de inducción, cuyas características mecánicas son controladas por el sistema de control y monitorización (12).The description developed so far is the which corresponds to the operation of the system when you perform a motor action, since the synchronous / induction machines (13) and (14) work in this state as synchronous / induction motors, whose mechanical characteristics are controlled by the system of control and monitoring (12).

En el proceso de frenado regenerativo, las máquinas síncronas o de inducción (13) y (14) funcionan como generadores síncronos o de inducción, produciendo una tensión alterna trifásica que se inyectará a los inversores (10) y (11). Estos inversores, trabajando en modo inverso, suministran una corriente continua, cuya tensión e intensidad vienen determinadas por las señales del sistema de control y monitorización del bloque (12). Esta energía eléctrica, obtenida del proceso de frenado regenerativo a través de los bloques (10), (11), (12), (13) y (14), se aplica a la batería de supercondensadores (8), mediante el bloque de conexión del bus de corriente continua (9).In the regenerative braking process, the synchronous or induction machines (13) and (14) function as synchronous or induction generators, producing a voltage three-phase alternate to be injected to the inverters (10) and (11). These inverters, working in reverse mode, provide a direct current, whose voltage and intensity are determined by the signals of the block control and monitoring system (12). This electrical energy, obtained from the braking process regenerative through blocks (10), (11), (12), (13) and (14), it is applied to the supercapacitor battery (8), by means of the block connection of the direct current bus (9).

El chopper (15), proporciona una tensión y corriente de salida V_{occ} e I_{occ}, respectivamente, cuyas magnitudes vienen predeterminadas por el sistema de control del chopper (16). La energía eléctrica transmitida por el chopper (15), que procede del frenado regenerativo, se aplica al electrolizador (17), produciendo hidrógeno y oxígeno. El hidrógeno generado, es comprimido mediante un compresor (18) que es activado por un motor eléctrico alimentado desde el bus de corriente continua mediante el inversor correspondiente, y se almacena en el depósito de hidrógeno (19) a alta presión. El hidrógeno almacenado en este módulo (19) tiene la posibilidad de alimentar a una pila de combustible (20) y/o a un motor auxiliar de combustión interna (37). El oxígeno generado en el electrolizador (17) se almacena en el depósito de oxígeno (33).The chopper (15), provides a tension and output current V_ {occ} and I_ {occ}, respectively, whose quantities are predetermined by the control system of the chopper (16). The electrical energy transmitted by the chopper (15), which comes from regenerative braking, is applied to the electrolyser (17), producing hydrogen and oxygen. The hydrogen generated is compressed by a compressor (18) that is activated by a motor electric powered from the DC bus via the corresponding inverter, and is stored in the hydrogen tank (19) at high pressure. Hydrogen stored in this module (19) has the possibility of feeding a fuel cell (20) and / or to an auxiliary internal combustion engine (37).

La tensión suministrada por la pila de combustible (20) se estabiliza mediante el bloque convertidor cc/cc (21), cuya corriente y tensión de salida vienen determinadas por su sistema de control correspondiente (22). La corriente eléctrica procedente del convertidor cc/cc (21) se aplica al bloque conmutador (23) el cual, mediante la señal del sistema de control (24), permite direccionar esta energía, bien hacia el bloque del bus de corriente continua (9) o bien hacia el inversor cc/ca (25), para su posterior inyección a la red eléctrica (38). El bloque (25) se controla por el sistema de control (26), para que la energía generada sea filtrada por el bloque (27), para inyectarla a la red de baja tensión (38).The voltage supplied by the battery fuel (20) is stabilized by the cc / cc converter block (21), whose output current and voltage are determined by its corresponding control system (22). Electric current from the dc / dc converter (21) is applied to the switching block (23) which, by means of the control system signal (24), allows direct this energy, either towards the current bus block continuous (9) or towards the DC / AC inverter (25), for later injection into the power grid (38). The block (25) is controlled by the control system (26), so that the generated energy is filtered by the block (27), to inject it into the low voltage network (38).

Las tensiones del bus de cc, obtenidas a partir de la batería de supercondensadores (8), de los inversores (10) y (11) y del convertidor cc/cc (17), así como de la pila de combustible (20), direccionada por el conmutador (23), se conectan mediante el bloque de conexión (9).The DC bus voltages, obtained from of the supercapacitor battery (8), of the inverters (10) and (11) and the cc / cc converter (17), as well as the battery fuel (20), addressed by the switch (23), are connected via the connection block (9).

Por otra parte, la energía mecánica procedente del motor auxiliar de combustión interna (37) se acopla mecánicamente al motor principal de combustión interna (34) mediante el módulo de acoplamiento mecánico (35). En este sentido se hace constar que la potencia mecánica suministrada por el motor principal del bloque (34) se complementa con la potencia mecánica del bloque (37).Moreover, the mechanical energy coming of the internal combustion auxiliary engine (37) is coupled mechanically to the main internal combustion engine (34) by the mechanical coupling module (35). In this sense it is done record that the mechanical power supplied by the main engine of the block (34) is complemented by the mechanical power of the block (37).

En la figura 3 se muestra la otra opción de funcionamiento del sistema integral de generación y almacenamiento de hidrógeno y oxígeno, con la energía procedente del frenado regenerativo de las máquinas síncronas y máquinas de inducción, de tracción eléctrica, instalado a bordo de un vehículo, para su posterior utilización en pilas de combustible. A diferencia del supuesto anterior, en este caso el sistema integral utiliza como energía eléctrica inicial, la energía eléctrica procedente de la catenaria, que se transmite al vehículo mediante el pantógrafo. El funcionamiento de este sistema, indicado en la figura 3, es el que se indica a continuación:Figure 3 shows the other option of operation of the integral generation and storage system of hydrogen and oxygen, with the energy coming from braking Regenerative of synchronous machines and induction machines, of electric traction, installed on board a vehicle, for subsequent use in fuel cells. Unlike previous assumption, in this case the integral system uses as initial electrical energy, the electrical energy coming from the catenary, which is transmitted to the vehicle using the pantograph. He operation of this system, indicated in figure 3, is the one that It is indicated below:

Se parte de la energía eléctrica suministrada por la catenaria (29), mediante el módulo de protección y adaptación de la catenaria (28), cuyas señales se modifican con el módulo de control (30). La tensión procedente del módulo de protección y adaptación de la catenaria (28) se rectifica mediante el puente totalmente controlado (7), cuya tensión de salida se modifica mediante el sistema de control (6) y se aplica a la batería de supercondensadores (8). La salida de la batería de supercondensadores (8) se conecta al bloque de conexión del bus de corriente continua (9) y su salida se conecta a los inversores (10) y (11), los cuales, en función de las señales de control y monitorización del bloque (12), generan dos sistemas trifásicos independientes de tensiones y frecuencias variables, que se aplican a dos máquinas eléctricas, que pueden ser síncronas o de inducción (13) y (14), estando los ejes de las mismas unidos a los ejes de las ruedas motrices (39) y (40).Be part of the electricity supplied by the catenary (29), through the protection and adaptation module of the catenary (28), whose signals are modified with the module control (30).
