Recently, as the demand for marine generators has rapidly increased, various technologies capable of supporting their effective operation have been widely developed/disseminated.

For example, Korean Patent Publication No. 10-2004-37525 (title: automatic voltage regulator for ship generator) (published on May 7, 2004), Korean Patent Publication No. 10-2013-123967 (name: ship generator engine Preheating system) (published on November 13, 2013) discloses an example of a technology related to a conventional marine generator in more detail.

In addition, Korean Patent Publication No. 10-2004-53812 (name: Distributed Parallel Operation Control Device for Ship Generators) (published on June 24, 2004) describes an example of the prior art related to parallel operation of ship generators in detail. has been initiated.

On the other hand, under the conventional ship generator operating system, for example, the ship generator parallel operation system as shown in FIG. 1, on the ship power management system 3 side, the load 2 ), by systematically controlling/managing the power supply procedure to the side, it is supported so that various equipment in the ship using electricity can stably perform their assigned operations.

At this time, on the side of the ship power management system 3, for example, 'function to remotely control the operation and stop of the ship generators 1a, 1b, 1c, 1d', 'remotely controlling the circuit breaker, the ship generator ( 1a, 1b, 1c, 1d) 'function to turn on or off', 'function to synchronize multiple ship generators (1a, 1b, 1c, 1d) under generator parallel operation mode', 'remotely control the speed governor, By adjusting the load of the ship generators (1a, 1b, 1c, 1d), the function of managing the ship generators (1a, 1b, 1c, 1d) so that they do not operate at more than the rated power, 'In case of heavy load operation with large required power In the ship generator (1a, 1b, 1c, 1d), the function of determining the remaining power 'and the like are systematically performed.

However, under such a conventional system, the ship power management system 3 assumes only a stable supply of power as the main management point, and recklessly controls the ship generators 1a, 1b, 1c, 1d and the load 2. Because of this, it causes a serious problem that the capacity of the ship generators 1a, 1b, 1c, 1d is excessively set / operated compared to the load.

For example, despite the situation in which the load on the load (2) side can be sufficiently covered only by the operation/input of the ship generator A (1a), the conventional ship power management system (3) side for stable supply of power, In addition to the generator A (1a), it causes a serious problem of excessive operation / input of the additional marine generator B (1b).

As another example, although the load on the load (2) side can be sufficiently covered only by the operation/input of the ship generators A and B (1a, 1b), the conventional ship power management system (3) provides a stable supply of power. In order to do this, in addition to the ship generators A and B (1a, 1b), a serious problem of excessively operating / inputting the ship generators C and D (1c, 1d) is caused.

Naturally, under a serious situation in which the capacity of the ship generators (1a, 1b, 1c, 1d) is excessively set / operated compared to the load, on the side of the ship operating entity, 'the overall 'Serious problem of excessive increase in fuel consumption', 'serious problem of excessive increase in harmful substance emissions from ship generators (1a, 1b, 1c, 1d)', as well as 'ship generators (1a, 1b, 1c, 1d) ) has no choice but to endure the serious problem of greatly shortening the lifespan of the device.

Hereinafter, with reference to the accompanying drawings, a parallel operation management apparatus of a ship generator according to the present invention will be described in more detail as follows.

As shown in FIG. 2, under the parallel operation system of the ship generator employing the present invention, the power supply procedure from the ship power management system 13 to the loads 12 of the ship generators 11a, 11b, 11c, and 11d. By systematically controlling/managing, it is supported so that various equipment in the ship using electricity can stably perform the operations assigned to them.

Even at this time, on the side of the ship power management system 13, for example, 'the function of remotely controlling the operation and stop of the ship generators 11a, 11b, 11c, 11d', 'remotely controlling the circuit breaker, the ship generator (11a, 11b, 11c, 11d) 'function to turn on or off', 'function to synchronize multiple ship generators (11a, 11b, 11c, 11d) under generator parallel operation mode', 'remotely control the speed governor , By adjusting the load of the ship generators 11a, 11b, 11c, 11d, a function of managing the ship generators 11a, 11b, 11c, 11d so that they do not operate at more than the rated power, 'heavy load operation with large required power' At the time of the ship generator (11a, 11b, 11c, 11d) to determine the surplus power function 'and the like are systematically performed.

Of course, even under the framework of the present invention, if, on the side of the ship power management system 3, only the stable supply of power is assumed as the main management point, the ship generators 11a, 11b, 11c, 11d and the load 12 ) If the control is reckless, a serious problem may be caused in that the capacity of the ship generators 11a, 11b, 11c, and 11d is excessively set / operated compared to the load.

Under such a sensitive situation, as shown in FIG. 2, in the present invention, under the communication system of the ship power management system 13, the ship generators 11a, 11b, 11c, 11d, and the load 12, 'current load' (12) Parallel of the ship generator unique to the present invention that can induce only the ship generators 11a, 11b, 11c, and 11d of the optimal size corresponding to the side load to be efficiently (minimally) operated / put in Measures to additionally provide/arrange the driving management device 100 are taken. In this case, the parallel operation management device 100 of the ship generator according to the present invention may take a structure that is dependent / installed in the program block of the ship power management system 13 depending on the situation.

At this time, as shown in Figure 3, the parallel operation management device 100 of the ship generator according to the present invention via the interface module 101, the ship power management system 13, the ship generators 11a, 11b, 11c, 11d), operation information storage module 102 communicating with loads 12, etc., SPO setting module 103, load receiving module 104, optimal SPO selection module 105, ship generator parallel operation request module ( 106), the optimal SPO conversion module 107, the upper limit load factor processing module 108, the lower limit load factor processing module 109, etc. are closely combined.

Here, the operation information storage module 102 side has its own information storage area, for example, registration information of the power management system 13, registration information of the ship generators 11a, 11b, 11c, 11d, and registration of the load 12. By stably storing/managing information, various setting information of the ship operator, various program source information for forming/maintaining communication/session, and program source information for performing the functions of each computational module, the ship generator according to the present invention It will play a supporting role so that the parallel operation management service can proceed normally without any problems.

Under this infrastructure, as shown in FIG. 4, the SPO setting module 103 side communicates with the ship power management system 13 through the interface module 101, and the ship generators 11a, 11b, 11c, 11d ) After checking the configuration, based on the number and capacity of the ship generators (11a, 11b, 11c, 11d), a movable 'generator parallel operation combination' is configured, and the configured generator parallel operation combination is the generator capacity The procedure for setting 'Stage for Parallel Operation of marine generators (SPO)', which is listed step by step according to the order from the smallest to the largest sum of , proceeds.

In the following description, for convenience, it is assumed that the ship generator A (11a) and the ship generator B (11b) have a capacity of 2760 KW, and the ship generator C (11c) and ship generator D (11d) have a capacity of 3680 KW. It is assumed that (of course, the capacity of such a ship generator can achieve various modifications depending on the situation).

Under the above procedure, as shown in FIG. 4, the SPO is 'SPO1 having a parallel operation combination in which only the ship generator A (11a) is operated/operated alone', and 'only the ship generator C (11c) is operated/operated alone. SPO2 having an operating parallel operation combination, 'SPO3 having a parallel operation combination in which the ship generator A (11a) and the ship generator B (11b) are interlocked and operated/operated', 'the ship generator A (11a) and Ship generator C (11c) and ship generator D (11d) are interlocked and operated / operated SPO7 having a parallel operation combination, 'ship generator A (11a) and ship generator B (11b), and ship generator C (11c) and ship generator D (11d) have a feature consisting of SPO8' having a parallel operation combination in which both are interlocked and operated. In this case, 'SPO1, SPO2, SPO3, ..., SPO7, SPO8' constituting the SPO means a parallel operation stage in which the sum of generator capacities increases as the number increases.

Through the above-described procedure, under a situation in which the generator parallel operation combination sets/completes the SPOs listed in stages according to the order from the smallest to the largest sum of generator capacities, the load reception module 104 side uses the interface module 101 as a medium. As a result, communication with the ship power management system 13 is performed, and a procedure for receiving the current total load amount of the loads 12 is performed (see FIG. 4).

](단, 상기 부하율은 100(%) 이하)을 연산하여, 상기 SPO(즉, SPO1,SPO2,SPO3,‥‥,SPO7,SPO8) 중에서, 현재 총 부하량 대비 부하율이 가장 큰 최적 SPO를 선정하는 절차를 진행하게 된다(도 4 참조)(물론, 이 경우, 부하율이 100%를 초과하는 케이스는 무시됨). In this way, when the current total load amount of the subordinates 12 is received/completed, the optimum SPO selection module 105 proceeds with a series of information reading routines, reads the current total load amount of the subordinates 12, and ceremony [

] (however, the load ratio is 100 (%) or less) to select the optimal SPO with the largest load ratio compared to the current total load among the SPOs (ie, SPO1, SPO2, SPO3, …… The procedure proceeds (see FIG. 4) (of course, in this case, the case where the load factor exceeds 100% is ignored).

Under this procedure, for example, when the current total load of the loads 12 is 2200KW, SPO1 having the largest load ratio to the total load (2200KW) is selected as the optimal SPO according to the above equation.

Through the above-described procedure, under a situation where the optimal SPO (eg, SPO1) having the largest load ratio to the current total load (eg, 2200KW) is selected/completed, on the side of the ship generator parallel operation request module 106, the optimal SPO selection module ( 105), proceed with a series of information reading routines, and proceed with the procedure of reading the optimal SPO (eg, SPO1) with the largest load ratio compared to the current total load (eg, 2200KW) (see FIG. 4). .
