Description

TECHNICAL FIELD [0001] The present invention relates to a fuel supply control system for an emergency power supply,

The present invention relates to a fuel supply control system, and more particularly, to a fuel supply control system for an emergency power supply capable of stably supplying emergency power to a safety facility in the event of fire or power failure.

Generally, buildings over a certain size have been mandated to install alarm, fire, and fire extinguishing facilities for the safety of building users. These safety facilities require a power source for operation, and an emergency generator has been installed to supply the power.

Such a conventional emergency generator operates automatically or manually only in the event of a fire or a power failure, and it is possible to operate an alarm facility, a fire fighting facility, and a fire fighting facility by supplying power to a predetermined load. Here, the load is divided into a general load, an emergency load, and a fire load.

The loads that consume electric power depend on the operation of the general building and the life of the user, and the emergency load and the fire load are loads consuming power in the event of a fire, a power failure, or a disaster.

In some cases, some of the emergency loads, such as elevator parts, lighting parts, and broadcasting facilities, are used as general loads in the event of a disaster, and emergency loads when a disaster occurs. As the load to be used.

Among these loads, the emergency generator is used as a standby power for supplying the emergency load and the power for the fire load. In the event that a part of the emergency load and the general disaster do not occur, it is operated by a commercial power source. In the event of a disaster, the emergency load and the fire load are selectively supplied by the emergency generator, .

In such a conventional emergency power system, the fire load and the emergency load are operated together with the generated power immediately at the beginning of the power failure or immediately after the generator is driven. That is, when a disaster occurs, the power for the emergency load and the fire load is switched to the emergency generator, and the generated power is simultaneously supplied by the emergency generator.

However, since the emergency generator is capable of generating generated power only when it is supplied with fuel in order to supply the generated power to the emergency load and the fire load, the fuel condition stored in the fuel tank has to be inspected. At this time, the fuel used for the emergency generator was usually stored in different fuel tanks for each emergency load and fire load.

Accordingly, the conventional emergency generator has a problem in that it can not supply the generated power to the fire-fighting load when a situation occurs in which the fuel for the fire-fighting load is insufficient when the generation power is supplied to the fire-fighting load for a long time in the event of a disaster.

On the other hand, when disaster is released, the emergency generator has a problem in that it can not supply the generated power to the emergency load if the emergency power supply is supplied to the emergency load for a long period of time.

In the drawings, like reference numerals refer to the same or similar functions throughout the several views.

First Embodiment

FIG. 1 is a view showing an exemplary fuel supply control system 100 according to a first embodiment of the present invention.

1, the fuel supply control system 100 according to the first embodiment of the present invention includes a fuel tank unit 110, a power generation unit 120, a load (not shown) for stably supplying fuel for emergency power, A height measuring sensor unit 140, a switchboard 150, and a fire signal detecting unit 160. The height measuring sensor unit 140,

First, the fuel tank unit 110 according to the present invention includes an emergency fuel tank 111 for storing emergency fuel and a fire-fighting fuel tank 112 for storing fire-fighting fuel. At this time, the emergency fuel and the fire-fighting fuel are the same fuel, such as diesel, gasoline or heavy oil. These fuels are the fuels needed to produce generated power in the case of a generator for an internal combustion engine.

The fuel tank unit 110 may be disposed adjacent to the emergency fuel tank 111 and the fire-fighting fuel tank 112, or may be disposed apart from each other. At this time, a check window 114 is provided in the emergency fuel tank 111 and the fire-fighting fuel tank 112, and a lock valve 113 is provided between the emergency fuel tank 111 and the fire-fighting fuel tank 112 .

The check window 114 can open the lock valve 113 when the fuel shortage is confirmed as a window for confirming the state of the corresponding fuel. At this time, when the lock valve 113 is opened, the neighboring fuel such as the fuel stored in the emergency fuel tank 111 can be moved to the fire-fighting fuel tank 112.

The fuel stored in the fire-fighting fuel tank 112 can be transferred to the emergency fuel tank 111. [ However, it is also possible to measure the height of the fuel stored in the fuel tank unit 110, not the check window 114, and determine whether the lock valve 113 is opened based on the measured height. This will be discussed later in FIG. 2.

Next, the power generation unit 120 according to the present invention plays a role of generating electricity by receiving any one of the emergency fuel and the fire-fighting fuel stored in the fuel tank unit 110. For this purpose, a configuration such as a circuit breaker, a converter, and a load breaker may be provided to generate the generated power by receiving the fuel as described above in the event of a disaster.

The power generator 120 may be a generator using an internal combustion engine using diesel, gasoline or heavy oil as fuel. The generator 120 may be of a type that is mounted on a driver's seat, a driver's seat, air-cooled, An unnecessary enclosure structure application) and an outdoor type may be installed in one or a plurality of parallel operation types.

At this time, it is preferable that the power generation unit 120 supplies power generation power to the load unit 130 through the switchboard 160. The reason for this is that the switchboard 160 supplies the main power supplied from the main power source 101 to the load in a state in which no disaster has occurred and is supplied from the emergency generator 120 in a state where a disaster has occurred And supplies the generated power to the load unit 130 to be described later.

Particularly, the power generation unit 120 interrupts the connection of the load 130 to the main power source 101 supplied from the power distribution panel through the switchboard 160 when a disaster occurs, and supplies the generated power to the load 130 . Specifically, the power generator 120 controls the connection of the switchboard 160 to supply the generated power first to the fire load, sequentially connects the emergency load 132 and the normal load according to the margin of the generated power, Lt; / RTI >

At this time, the switchgear 160 is sequentially charged in the order of the fire load 131 and the emergency load 132 in accordance with the control of the electric power generator 120 when the generated electric power is supplied. In accordance with the overload, The power to the load unit 130 can be supplied.

Next, the load unit 130 according to the present invention is a power source that exists in a facility (facility) in which safety facilities such as an alarm facility, a fire protection facility, and a fire extinguishing facility are essentially installed. In a normal case where no disaster occurs, The main power source 101 of the main power source unit 160 consumes electric power to perform the desired function and receives the generated power from the power generation unit 120 when a disaster occurs.

To this end, the load unit 130 includes a general load, an emergency load, and a fire load for the disaster prevention and rescue structure in a disaster situation. The fire load and the emergency load refer to the loads required for disaster response such as fire fighting, disaster prevention and evacuation by the load defined by the relevant laws, regulations, and the like. For example, a fire load refers to a load that must be operated at the time of a disaster such as a fire pump, various detectors, and lighting for evacuation.

On the other hand, the emergency load is used for the purpose of providing the safety maintenance assistance of the facility and the convenience of the facility user in a situation in which no disaster occurs, and a load used for auxiliary purposes for evacuation and disaster prevention under a disaster situation, It means the same load.

Accordingly, the load unit 130 according to the present invention receives the generated power from the power generation unit 120 described above in the event of a disaster or a power outage from the power generation unit 120 and receives the fire load 131 and the emergency load 132, As shown in FIG.

As described above, in order to selectively operate either the fire load 131 or the emergency load 132, the power generation unit 120 must be supplied with the generated power continuously.

However, in the conventional case, when the generated power is supplied to the fire load 131 from the power generator 120 for a long time by the fire load 131, the fuel for the emergency load 132 is bottomed and not operated properly. Accordingly, in order to overcome such disadvantages, the power generation unit 120 according to the present invention checks the state of the corresponding fuel from the fuel tank unit 110 when the corresponding generated power is supplied to the load unit 130.

For example, if it is determined that the state of the fire-fighting fuel stored in the fire-fighting fuel tank 112 is insufficient, the lock valve 113 provided in the fuel tank unit 110 is opened, Thereby controlling the fuel movement between the fuel tanks 111.

That is, when the emergency valve 113 is opened to move the emergency fuel stored in the emergency fuel tank 111 to the fire-fighting fuel tank 112 and the emergency fuel stored in the emergency fuel tank 111 is judged to be deficient, The opening of the lock valve 113 is controlled by the electric power generator 120 so that the fire-fighting fuel stored in the tank 112 is moved into the emergency fuel tank 111.

At this time, checking the status of fire-fighting fuel and emergency fuel refers to conditions such as height, density and weight of the fuel. However, it is needless to say that the present invention is not limited to this, but may be applied to the present embodiment as long as it is possible to know how much the fuel is. Here, a height measurement sensor is provided to check the height of the fuel.

That is, the height measurement sensor unit 140 according to the present invention includes at least one height measurement sensor, and checks the height of the fuel stored in the fuel tank unit 110 described above. However, it goes without saying that other means for determining the height of the fuel instead of the sensor can be applied in the present embodiment.

Lastly, the fire signal detection unit 150 according to the present invention is responsible for generating a fire signal by monitoring a fire generated in a facility (facility) in which safety facilities such as an alarm facility, a fire protection facility, and a fire extinguishing facility are installed . The fire signal may be supplied to the power generation unit 120 described above.

When the power supply unit 120 stops power supply from the main power source 101 to the load unit 130 during a power failure, the power generation unit 120 receives the power from the fire signal detection unit 150 A fire signal is provided or a power failure signal is provided. As described above, the power generator 120 is a generator that is operated due to a sudden interruption of the power supply from the main power source 101 to the load unit 130.

Hereinafter, the power generator 120 described above will be described in more detail.

FIG. 2 is a diagram illustrating a detailed configuration of the power generator 120 according to an embodiment of the present invention.

2, the power generation unit 120 according to an embodiment of the present invention includes a power generation control unit 121, a fuel state check unit 122, a first lock valve control unit 123, And a valve control unit 124.

First, the generated power control unit 121 according to the present invention generates the generated power using the emergency fuel provided in the fuel tank unit 110 to supply the generated power to the emergency load 132, if necessary, ). If necessary, in order to supply the generated power to the fire-fighting load 131, the generated power is generated using the fire-fighting fuel provided in the fuel tank unit 110, and then supplied to the fire-fighting load 131.

Next, the fuel state check unit 122 according to the present invention is provided with the fuel state information of the emergency fuel and the fire-fighting fuel measured by the height measurement sensor unit 140. At this time, the fuel status information means information of the remaining amount of the emergency fuel and the fire-fighting fuel remaining in the fuel tank unit 110.

Next, the first lock valve control unit 123 according to the present invention controls the first lock valve control unit 123 to supply the fuel shortage signal included in the fuel state information checked in the fuel state check unit 122 The emergency fuel stored in the emergency fuel tank 111 can be injected into the fire fighting fuel tank 112 by controlling the lock valve 113 provided in the fuel tank unit 110 to be opened.

Meanwhile, the second lock valve control unit 124 according to the present invention provides an emergency fuel shortage signal included in the fuel state information checked in the fuel state check unit 122 while supplying the generated power to the emergency load 132 It is possible to inject the fire fuel stored in the fire fighting fuel tank 112 into the emergency fuel tank 111 by controlling the lock valve 113 provided in the fuel tank unit 110 to be opened.

As described above, in the present embodiment, the power generation unit 120 checks the state of the fuel corresponding to the supply of the generated power to the load unit 130, thereby opening the shortage lock valve 113, It is possible to stably supply the generated power to the load section 130 without fuel shortage even if either the fire load 131 or the emergency load 132 continues for a long period of time by controlling the fuel movement between the emergency fuel tank 111 and the emergency fuel tank 111 It will be possible.

Second Embodiment

FIG. 3 is a view showing a fuel supply control system according to a second embodiment of the present invention, and FIG. 4 is a diagram showing the configuration of the power generation section 30 of the fuel supply control system according to the second embodiment of the present invention In more detail.

3, the fuel supply control system 200 according to the second embodiment of the present invention includes a fire signal unit 80, a main power source 10, a switchboard 20, a power generator 30, And a load portion 40. [ Each configuration will be explained regardless of the order.

Here, the main power supplied from the main power source 10 is supplied to the transformer 213 through the automatic section switch 211 and the MOF (metering out of fit) 212. The transformer 213 converts the main power into a low voltage available in the load section 40 and supplies it to the load section 40. At this time, an air interrupter (ACB) 214 is installed between the load unit 40 and the power converter to cut off the connection between the load unit 40 and the main power in case of an accident.

The power demand controller 221 of the power management system 22, the power factor controller 222 and the management system 223 manage the reception and distribution of the main power in the transforming and distributing process, And the monitoring result is transmitted to the user.

The switchboard 20 according to the present invention includes a phase capacitor 215 and a surge protector 216. The circuit breaker 20 includes a phase capacitor 215 and a breaker 216 for connecting or disconnecting the service protector 216 to / , 217, 218).

The power generation unit 30 according to the present invention is connected to the switch unit 23 and is connected to or disconnected from the load unit 40 by the switch unit 23. The switcher 23 is controlled by the emergency generator 30 receiving the fire signal from the fire signal unit 80 so that all or a part of the load 40 is connected to the emergency generator 30 do.

Next, the load section 40 according to the present invention is divided into a general load 50, an emergency load 60 and a fire load 70. The normal load 50 is connected to the main power and the emergency load 60 And the fire-fighting load 70 are connected to the main power through the switch 23. [

However, when a fire occurs, the general load 50 is operated by the main power until the main power is cut off, and when the main power is cut off, it is connected to the power generation unit 30 by using the switch 23 . At the time of a power failure, the power generator 30 is directly connected to the power generator 30 by the power converter 23 and is operated by generated power.

Meanwhile, the emergency generator 30 according to the present invention receives a fire signal from the fire signal unit 80, or detects a detected value of the main power transmitted from the power management system 22 or a detected value of the main power measured directly And it is judged whether a disaster occurs or not.

When a disaster occurs, the power generator 30 controls each of the change-over units 23 so that the load 40 connected to the change-over unit 23 is disconnected from the main power source 10, And supplies power to the load section 40 separated from the main power source 10. [ The power generator 30 first controls the switcher 23 to connect the load 40 to the load 40 so that the load 40 is connected to the power generator 30, The emergency load 60 and the fire load 70 by selectively controlling the circuit breakers 52, 62, and 72, respectively, to supply the generated power.

Here, in order to supply the generated power to the emergency load (60) and the fire load (70) among the load portion (40), the power generation portion (30) can produce the generated power only after receiving the fuel necessary for generating the generated power. The fuel tank unit 90 is further provided for this purpose.

That is, the fuel tank unit 90 according to the present invention includes an emergency fuel tank 91 for storing the emergency fuel and a fire-fighting fuel tank 92 for storing the fire-fighting fuel. At this time, the emergency fuel and the fire-fighting fuel are the same fuel, such as diesel, gasoline or heavy oil. These fuels are the fuels necessary for producing power generation when the power generating unit 30 for an internal combustion engine is used.

The fuel tank unit 90 may be disposed adjacent to the emergency fuel tank 91 and the fire-fighting fuel tank 92, or may be disposed apart from each other. At this time, a check window 94 is provided in the emergency fuel tank 91 and the fire-fighting fuel tank 92, and a lock valve 93 is provided between the emergency fuel tank 91 and the fire-fighting fuel tank 92 do.

When the check window 94 confirms fuel shortage as a window for confirming the state of the corresponding fuel, the lock valve 93 can be opened. At this time, when the lock valve 93 is opened, the fuel in the neighboring fuel, for example, the fuel stored in the emergency fuel tank 91, can be moved to the fire-fighting fuel tank 92.

However, the height of the fuel stored in the fuel tank portion 91 other than the check window 94 may be measured and it may be determined whether or not the lock valve 93 is opened based on the height of the fuel. This will be explained later. Accordingly, the power generation unit 30 according to the present invention receives either the emergency fuel stored in the fuel tank unit 90 and the fire-fighting fuel, generates the generated power, and supplies the generated power to the corresponding load unit 40 .

4, includes a generator 31, a power generation control unit 32, a breaker 331, and a measurement element 325. [ The power generation control section 32 includes a controller 321, an instrument 322, a relay 323, and a communicator 324.

Here, the generator 31 according to the present invention generates generated power by controlling the power generation control unit 32 at the time of occurrence of a disaster, and generates power to the circuit breaker 331, the transfer unit 23, and the load breakers 52, 62, And is connected to the load unit 40 to provide generated power. The generator 31 may be a generator using an internal combustion engine using diesel, gasoline or heavy oil as fuel. The generator 31 may be of a type that is mounted on a driving platform, a driving class, air cooling type, a soot reduction device, a low noise type Structure application), and outdoor type can be constructed by installing one or a plurality of parallel operation type.

On the other hand, the power generation control unit 32 confirms a disaster situation including a power failure and a fire by a fire signal unit 80 or a measuring device such as an ammeter or a voltmeter, and drives the generator 31 when a disaster occurs to secure generation power And also supplies the generated power to the load unit 40 by the load circuit breakers 52, 62, and 72 and the circuit breaker 331.

The power generation control unit 32 supplies the generated power to the fire load 70 in preference to the emergency load 60 and the normal load 50 in order of power supply to the fire load 70, .

To this end, the power generation control unit 32 disconnects the main power from the load unit 40 when a disaster occurs, thereby stopping the supply of power to the load unit 40. When electric power is generated by the generator 31, the fire-fighting load 70 and the emergency-power generating unit 30 are connected by the switching unit 23 and the breaker 331, The load breaker 72 is connected to supply the electric power to the fire load 70.

The power generation control unit 32 supplies the generated power to the fire load 70 and compares the generated power with the amount of power consumed by the fire load 70 to calculate the excess of the generated power, The load breaker 621 of the emergency load 60 is connected to supply the generated power to the emergency load 60. [

The power generation control unit 32 calculates the surplus power of the generated power while supplying the generated power to the emergency load 60 and the fire load 70. When the surplus power exists, the load breaker 52 of the normal load 50, So that the generic load 50 is supplied with generated power.

Particularly, when the emergency load 60 is connected, the power generation control unit 32 prioritizes the emergency load capable of evacuating the facility user, inputting the fire-fighting force, and assisting the disaster prevention like the elevator load to the emergency load 60, .

In order to selectively operate either the emergency load 60 or the fire load 70 through the control relationship between the switchboard 20, the power generation unit 30 and the load unit 40, 30) must be continuously supplied with generated power.

However, in the conventional case, when the generated power is supplied to the fire-fighting load 70 from the power generating unit 30 for a long time by the fire-fighting load 70 or vice versa, the fuel for the emergency load 60 does not work well.

Therefore, in order to overcome the above-described disadvantage, the power generation unit 30 according to the present invention checks the state of the corresponding fuel from the fuel tank unit 90 when supplying the corresponding generated power to the load unit 40.

For example, if it is determined that the state of the fire-fighting fuel stored in the fire-fighting fuel tank 92 is insufficient, the lock valve 93 provided in the fuel tank unit 90 is opened, Thereby controlling the fuel movement between the fuel tanks 91.

That is, when the emergency valve 93 is opened to move the emergency fuel stored in the emergency fuel tank 91 to the fire fighting fuel tank 92 and the emergency fuel stored in the emergency fuel tank 91 is judged to be deficient, The opening of the lock valve 93 is controlled by the electric power generating section 30 so that the fire-fighting fuel stored in the tank 92 is moved into the emergency fuel tank 91.

At this time, checking the status of fire-fighting fuel and emergency fuel refers to conditions such as height, density and weight of the fuel. However, it is needless to say that the present invention is not limited to this, but may be applied to the present embodiment as long as it is possible to know how much the fuel is. Here, a height measurement sensor is provided to check the height of the fuel.

That is, the height measurement sensor unit 95 according to the present invention includes at least one height measurement sensor, and checks the height of the fuel stored in the fuel tank unit 90 described above. However, it goes without saying that other means for determining the height of the fuel instead of the sensor can be applied in the present embodiment.

Meanwhile, the load unit 40 described above divides each load into a small group load, and controls the connection / disconnection by arranging load breakers 521, 621, and 721 for each group of loads. Specifically, each load section 40 is divided into a general load 50, an emergency load 60, and a fire load 70 as described above.
