Description

Compared to conventional systems that use diesel, gasoline, or the like as energy, more and more traffic equipment adopts a pure electricity or hybrid system as its energy utilization system.

  Taking a ship as an example, the control and distribution scheme in the power of the ship must be distinguished from land vehicles.

  In order that the technical features and practical effects of the present invention can be understood and implemented based on the contents of the specification, the present invention will be described in detail with reference to preferred embodiments shown in the drawings.

  First, referring to FIG. 1, it is a schematic diagram showing the structure of a ship having a plurality of engines that are actually utilized in an embodiment of the present invention. As shown in FIG. 1, a person having ordinary knowledge can realize the present invention. Therefore, a dynamic power distribution system that multiplexes input / output of onboard electric energy of the present invention by exemplifying a ship power system in this embodiment. The basis for implementing this control method.

  FIG. 1 discloses a marine power system including a plurality of engines. The marine power system includes a battery module 100, a DC voltage raising equipment 101, a DC bus module 300, an AC / DC bidirectional voltage conversion equipment 201, and at least Two generators (200a, 200b), an AC bus module 400, at least two actuators (501a, 501b), and at least two engine motors (500a, 500b) are included.

  The DC voltage raising equipment 101 is connected to the battery module 100, the DC bus module 300 is connected to the DC voltage raising equipment 101, and the AC / DC bidirectional voltage conversion equipment 201 is simultaneously connected to the DC bus module 300 and the AC bus module 400. Connecting.

  At least two generators (200a, 200b) are connected to the AC bus module 400, and at least two actuators (501a, 501b) are connected to the DC bus module 300. At least two actuators (501a, 501b) are connected to at least two engine motors (500a, 500b), respectively.

  In order to make the description of the present embodiment convenient, an example of a marine power system including a double engine is taken as an example of a marine power system including the plurality of engines. In fact, the marine power system including a plurality of engines described in the present embodiment is not limited to being used for a marine power system including a double engine.

  1, the power system can be operated by freely distributing energy, and is used for energy distribution mainly through operation of a temperature controller or a converter provided in the DC bus module 300. It is done. In addition, the AC bus module 400 or the DC bus module 300 can be connected to a hotel load on a ship equipped with a plurality of engines.

  Next, referring simultaneously to FIG. 2A to FIG. 2F, it is a schematic diagram showing the flow of each execution mode and the mode switching according to the present invention. The dynamic distribution control method for multiplex input / output of on-board electrical energy described in FIGS. 2A to 2F mainly includes a plurality of main steps, and one mode is set in each main step. Including.

  The modes mentioned in the above paragraphs include a step (a) in which a ship having a plurality of engines executes a pure battery mode, a step (b) in which a ship with a plurality of engines executes a cruising range extended charging mode, A step (c) in which a ship equipped with an engine executes a super-high power mode; a step (d) in which a ship equipped with the plurality of engines executes a finite cruising range extended charging mode; A step (e) of executing a propulsion mode, a step (f) of a vessel having the plurality of engines executing a finite power generation propulsion mode, and a step (g) of a vessel having the plurality of engines executing a non-navigation mode. is there.

  Assuming this, FIG. 2 (a) to FIG. 2 (f) show how the dynamic distribution control method for multiple inputs and outputs of onboard electrical energy in this embodiment is performed when switching between the modes. Disclose how to implement the best decision-making method. In FIG. 2 (a) to FIG. 2 (f), “applicable” is displayed because, when determining the step, the mode is switched only when the condition is satisfied, and the opposite is true. At other times, the other situation becomes “non-conforming”, which means that the mode in the main step is continued and the sub-steps in the main step are sequentially repeated.

  In order to easily understand the judgment conditions referred to in all the sub-steps of the present embodiment, the judgment conditions are arranged here. The first electric energy described in FIGS. 2A to 2F of this embodiment is 20%, the second electric energy is 30%, the third electric energy is 50%, 4 The amount of power is 80%. Next, the first rotation speed is 1260 rotations per minute (rpm), and the second rotation speed is 1080 rotations per minute (rpm). Regarding the determination condition of the time period, the first period is 15 seconds, the second period is 5 seconds, and the third period is 120 seconds.

  Referring first to FIG. 2 (a), what is shown in FIG. 2 (a) is the most important step in this embodiment. The dynamic distribution control method for multiple inputs and outputs of on-board electrical energy of this embodiment mainly starts with energy saving and carbon dioxide emission reduction.

  Compared with the concept of conventional single-powered ships and further double-powered ships that mainly use diesel power generation for propulsion and reserve electric propulsion, the feature of this embodiment is a pure battery in the main step (a). The mode is the priority and the main execution mode.

  That is, the control methods executed in FIGS. 2 (a) to 2 (f) of the present embodiment are all performed under the conditions permitted by the operating status of the hardware of the ship equipped with a plurality of engines. It is determined most preferentially to return to the mode execution in ().

  Accordingly, the main steps (a) to (g) and substeps thereof will be described below. First, the pure battery mode in step (a) includes steps (a1) to (a5), and in the execution of the pure battery mode described in step (a), the steps in (a1) to (a5) The above determinations are repeated in order.

  In this embodiment, a ship equipped with a plurality of engines turns on the battery module 100 and turns off all of the at least two generators (200a, 200b) in the pure battery mode of step (a). The ascending equipment 101 limits the output power to 250 kilowatts or less, and the AC / DC bidirectional voltage conversion equipment 201 restricts the output power to 34 kilowatts or less. Also, in this mode, a vessel equipped with multiple engines must be maintained at a maximum navigation speed of 5-7 knots. In the mode of step (a), the voltage of the DC bus module 300 must be maintained by the DC voltage raising equipment 101.

  In step (a1), first, the state of electric energy of the ship equipped with the plurality of engines, the required traction force, the state of each engine (at least two actuators (501a, 501b) and at least two engine motors (500a, 500b)), inspecting the state of the main battery (the state of the battery module 100), the state of the AC / DC bidirectional voltage conversion equipment, the state of the DC voltage rise / voltage drop equipment and the state of each generator, and the determination step (a2 ) Is executed, step (g) is executed when all the states of the respective engines of the ship equipped with the plurality of engines cannot be operated, and step (a3) is executed at the opposite time.

  Step (a1) is mainly a determination of a precondition for determining whether or not the hardware conditions of a ship equipped with a plurality of engines can be operated during the first execution of the present embodiment. Among these, the state of each engine corresponds to the embodiment of the marine power system including a plurality of engines in FIG. 1, and indicates the state of the actuator (501a, 501b) and the engine motor (500a, 500b). If either of the actuators (501a, 501b) and the engine motors (500a, 500b) cannot be operated, it is determined that the engine cannot be operated. Therefore, according to the present embodiment, when the engine motors (500a, 500b) cannot be operated normally and normally, it is said that all the states of the respective engines cannot be operated.

  Therefore, as can be seen from the step (a1), the hardware state in the power system (for example, the state of the main battery, the state of the AC / DC bidirectional voltage conversion facility, the state of the DC voltage rise / voltage drop facility, and each generator) If the execution side (actuators (501a, 501b) or engine motors (500a, 500b)) cannot be operated even if both are normal, a ship equipped with multiple engines is similarly step (g ) (Only in the non-navigable mode in FIG. 2 (f)).

  Therefore, when it is determined that a ship having a plurality of engines can be propelled, the determination in step (a3) is continued. Judgment step (a3): Step (e) (FIG. 2 (e)) when either the state of the DC voltage rise / voltage drop facility of the ship equipped with the plurality of engines or the state of the main battery cannot be operated. ) Is executed, and in the opposite case, step (a4) is executed.

  Step (e) is a pure power generation propulsion mode, and when the DC voltage rise / voltage drop equipment state or the main battery state cannot be operated, the power of the battery module 100 is supplied to a plurality of engines. This corresponds to the fact that it cannot be supplied completely on the propulsion power of the ship equipped. Therefore, when a ship equipped with a plurality of engines has to move forward, it can only be selected to proceed to the pure power generation propulsion mode of step (e).

  Next, determination step (a4): if the state of the electric energy of the ship equipped with the plurality of engines is smaller than or equal to the first electric energy, execute step (b) (FIG. 2 (b)), and When is reversed, step (a5) is executed. The first power amount is 20% in the present embodiment. A specific definition is that the remaining amount of the battery module 100 in FIG. 1 is 20%. In this case, the remaining battery module 100 is insufficient for a ship having a plurality of engines to continue to execute the pure battery mode in step (a), so the cruising distance extension charging mode is switched to step (b). To perform.

  Determination step (a5): When the state of the electric energy of the ship equipped with the plurality of engines is greater than or equal to the second electric energy, and the required traction force is greater than the first period maintained at the first rotational speed, Step (c) (FIG. 2 (c)) is executed, and in the opposite case, step (a) is executed. The necessary traction force specifically means the rotational speed when the engine motor (500a, 500b) in FIG. 1 is operated, and thus the first rotational speed is 1260 revolutions per minute (rpm). .), And the first period is 15 seconds.

  The determination condition in step (a5) is used for determining whether or not the propulsive force of a ship equipped with a plurality of engines at the present time is sufficient. When the condition of step (a5) is reached, the reason for switching to step (c) and executing the super high power mode is that the super high power mode can provide a large propulsive force to a ship having a plurality of engines.

  Next, referring to FIG. 2B, FIG. 2B illustrates the cruising range extended charging mode switching and determination steps. Step (b) includes steps (b1) to (b6) and sequentially repeats steps (b1) to (b6). First, in step (b1), the state of each engine of the ship equipped with the plurality of engines is inspected, and if all the states of each engine cannot be operated, step (g) is executed. (B2) is executed. This step is the same as step (a) described above, and is mainly used to determine whether the execution side (actuator (501a, 501b) or engine motor (500a, 500b)) can operate normally. It is done. When it is operating normally, the determination step (b2) is continued, and when it is opposite, the operation proceeds to the non-navigable mode in step (g).

  Next, the determination step (b2): When the state of the AC / DC bidirectional voltage conversion facility of the ship equipped with the plurality of engines or the state of each of the generators cannot be operated, step (a) is executed, and the reverse Step (b3) is executed. In step (b2), it is determined whether or not the ship itself having a plurality of engines is still capable of providing propulsion power, and at the same time, the surplus power generation amount is used for charging the battery module 100, whereby both AC and DC are charged. In order to maintain the propulsive force of a ship equipped with a plurality of engines when the direct voltage conversion facility 201 or each generator (200a, 200b) cannot provide propulsive power and the battery module 100 cannot be charged, the step (a ) Can only return to pure battery mode.

  If the cruising range extended charging mode in step (b) can be continued, the process further proceeds to step (b3). Judgment step (b3): When the state of each generator of the ship equipped with the plurality of engines is not able to operate a part of the generators, execute step (d), and if the opposite is true, execute step (b4) To do.

  In this state, it is a selective strategy. To put it simply, some generators (200a or 200b) can no longer operate, but one generator (200a or 200b) still produces finite power. In such a case, power can be supplied and the battery module 100 can be charged. Therefore, when the situation of step (b3) occurs, the finite cruising distance extension charging mode in step (d) is executed.

  And determination step (b4): If the state of the DC voltage increase / voltage drop facility of the ship equipped with the multiple engines or the state of the main battery cannot be operated, execute step (e), Step (b5) is executed. In step (b4), the battery module 100 mainly determines whether it can be charged by accepting an external current.

  Therefore, in the case where the DC voltage increase / voltage decrease facility 101 or the battery module 100 cannot be operated, in addition to not being able to supply propulsion power to a ship equipped with a plurality of engines, the energy for charging the battery module 100 in the cruising range extended charging mode is also included. It will be wasted. Thereby, when there exists the condition in step (b4), it progresses to the pure electric power generation propulsion mode in step (e).

  Also, the determination step (b5): when the state of the electric energy of the ship equipped with the plurality of engines is greater than or equal to the fourth electric energy, the step (a) is executed, and in the opposite case, the step (b6) Execute. When the determination is made up to step (b5) and the mode is switched to the mode of another step, it indicates that the cruising range extended charging mode described in step (b) is still in good operation.

  Thereby, when the operation of the extended cruising distance charging mode is satisfactory, the amount of power of the battery module 100 can be increased to some extent without fail. When the battery module 100 returns to 80% of the fourth power amount due to the operation of the extended mileage charging mode, it indicates that the battery module 100 has sufficient energy and can execute the pure battery mode in the step (a).

  Finally, determination step (b6): a second period in which the state of the electric energy of the ship equipped with the plurality of engines is greater than or equal to the second electric energy and the necessary traction force is maintained at the second rotational speed. If it is greater, step (c) is executed; otherwise, step (b) is executed.

  The reason for the presence of step (b6) is to save the switching time in the pure battery mode and the super-power mode of a ship equipped with a plurality of engines. That is, a ship equipped with a plurality of engines, even in the cruising range extended charging mode of step (b), if it meets specific conditions and needs, ignores switching to the pure battery mode of step (a) and directly steps ( c) can be directly switched to the super-power mode, and a ship equipped with a plurality of engines is used to respond to an emergency and quick power demand in the cruising range extended power mode.

  In step (b6), the second electric energy is 30%, the second rotational speed is 1080 revolutions per minute (rpm), and the second period is 5 seconds. . In the present embodiment, when maintaining the cruising range extended charging mode in step (b), the battery module 100 is turned on and all of the at least two generators (200a, 200b) are started in parallel.

  At the same time, the DC voltage raising equipment 101 limits the charging power of the battery module 100 to 100 kilowatts or less, and the AC / DC bidirectional voltage conversion equipment 201 limits the output power to 140 kilowatts or less. In this mode, the maximum speed requirement of the ship is 5 knots. Under the operation of step (b) mode, the voltage of the DC bus module 300 must be maintained through the AC / DC bidirectional voltage conversion equipment 201.

  Next, as shown in FIG. 2 (c), the mode executed in step (c) in FIG. 2 (c) is a super-power mode. In this embodiment, in this mode, the battery module 100 is turned on, and all of the at least two generators (200a, 200b) are started in parallel.

  The DC voltage raising equipment 101 limits output power to 286 kilowatts or less, and the AC / DC bidirectional voltage conversion equipment 201 limits output power to 150 kilowatts or less. At the same time, in this mode, the output power to the Hotel Load must be reduced from 35 kilowatts to 25 kilowatts, and in this mode, a multi-engine vessel must be kept at a maximum speed of 9 knots. . Under the operation of the step (c) mode, the voltage of the DC bus module 300 must be maintained through the DC voltage raising equipment 101.

  Substeps in step (c) include steps (c1) to (c5) and sequentially repeat steps (c1) to (c5). First, in step (c1), the state of each engine of the ship equipped with the plurality of engines is inspected, and if all the states of each engine cannot be operated, step (g) is executed. (C2) is executed.

  Next, determination step (c2): the state of the AC / DC bidirectional voltage conversion facility of the ship equipped with the plurality of engines cannot be operated, the state of the engines cannot be partially operated, or the state of the generators is When a part of operation cannot be performed, step (a) is executed, and when it is opposite, execution step (c3) is executed. In this case, since the propulsion power cannot be additionally supplied to the ship equipped with the plurality of engines through the power generation method, it indicates that the mode is switched to the pure battery mode in step (a).

  Judgment step (c3): If either of the state of the DC voltage rise / voltage drop facility of the ship equipped with the plurality of engines or the state of the main battery cannot be operated, execute step (e), At the opposite, step (c4) is executed. In this case, since the battery module 100 cannot supply additional power, it indicates switching to the pure power generation propulsion mode in step (e).

  Determination step (c4): Whether the state of the electric energy of the ship equipped with the plurality of engines is greater than or equal to the third electric energy, and whether the required traction force is smaller than the third period maintained at the second rotational speed Or if they are equal, execute step (a), otherwise execute step (c5). If it is determined in step (c4) that the state of electric energy of the ship equipped with a plurality of engines is within an allowable range and the emergency has been canceled or excessive propulsion power is no longer necessary, the mode is changed to step (a ) To switch to the pure battery mode. In step (c4) of the present embodiment, the third electric energy is 50%, the second rotation speed is 1080 rotations per minute (rpm), and the third period is 120 seconds. is there.

  Finally, determination step (c5): the state of the electric energy of the ship equipped with the plurality of engines is smaller than the first electric energy, or the state of the electric energy is smaller than the third electric energy, and the necessity If the traction force is less than or equal to the third period maintained at the second rotational speed, step (b) is executed, and if vice versa, step (c) is executed. When the determination condition of step (c5) is satisfied, the remaining amount of the battery module 100 is already less than 20% of the first electric energy, or the remaining amount of the battery module 100 is already smaller than 50% of the third electric energy, And a vessel with multiple engines had a time of less than or equal to 1080 revolutions per minute (rpm) was 120 seconds. The former situation indicates that the battery module 100 cannot already support maintaining the propulsion power required for the super-power mode in step (c), the latter situation does not currently require the use of excessive propulsion power, Further, since the battery module 100 has already consumed a certain amount of power, the battery module 100 proceeds to the cruising range extended charging mode in step (b).

  Next, as shown in FIG. 2D, step (d) in FIG. 2D is a finite cruising range extended charging mode. In this embodiment, in this mode, the battery module 100 is turned on, and at least two generators (200a or 200b) are started in parallel.

  The DC voltage raising equipment 101 limits the charging power of the battery module 100 to 52 kilowatts or less, and the AC / DC bidirectional voltage conversion equipment 201 limits the output power to 52 kilowatts or less. In the mode of step (d), the voltage of the DC bus module 300 must be maintained through the AC / DC bidirectional voltage conversion equipment 201. When performing the finite cruising range extended charging mode of step (d), the voltage of the DC bus module 300 must be maintained through the AC / DC bidirectional voltage conversion equipment 201. In this mode, the speed of a ship equipped with a plurality of engines is limited to a maximum of 4 knots.

  The finite cruising range extended charging mode described in step (d) includes steps (d1) to (d4) and sequentially repeats steps (d1) to (d4). First, in step (d1), the state of each engine of the ship equipped with the plurality of engines is inspected, and when all the states of the respective engines cannot be operated, step (g) is executed. (D2) is executed.

  Next, determination step (d2): when the state of the AC / DC bidirectional voltage conversion facility of the ship equipped with the plurality of engines cannot be operated or the state of each of the generators cannot be operated, step (a) is performed. When it is executed, the step (d3) is executed at the opposite time. In this case, since there is no generator (200a or 200b) capable of supplying power or charging the battery module 100, it indicates that the mode is switched to the pure battery mode in step (a).
