Referring to FIG. 1, a railroad history power management apparatus according to an embodiment of the present invention includes a power generation apparatus 10, a power storage apparatus 20, a PCS 30, and an integrated management server 40.

The power generation apparatus 10 produces electrical energy with auxiliary energy.

The auxiliary energy may include renewable energy, regenerative energy, fuel cell energy, and the like.

Renewable energy includes solar energy, wind power, water power, and intelligence. In this embodiment, it is understood that the renewable energy collectively refers to energy that can be obtained from nature and converted into electric energy.

The regenerative energy is the energy obtained by the kinetic energy of the train when the regenerative braking system, that is, when the train decelerates for operation or braking. Such regenerative energy can contribute to the energy saving because it is the energy generated during the operation and braking of the vehicle.

Fuel cell energy is the energy generated by the ionization reaction of hydrogen and oxygen.

For reference, the auxiliary energy in the present embodiment is not limited to the above-described embodiment, and may include various kinds of energy that can be converted into electric energy to be supplied to the historical facility 50. [ The history facility 50 may include an air conditioner 51, a lighting device 52, a computer 53, and a communication device 54. In addition, all the facilities installed to operate the history may be included have.

In addition, the power system collectively refers to electric power facilities that supply electric power produced from a power plant or the like to a railway power grid. In this specification, the power system can include both power distribution equipment (22.9kV switchboard), high-power transformer, and power equipment that supplies power to the historical power grid through the switchboard (AC 6.6kV switchboard).

For reference, the present embodiment will be described with reference to renewable energy, regenerative energy, and fuel cell energy.

The power generation apparatus 10 includes a renewable energy power module 11, a regenerative energy power module 12, and a fuel cell power module 13.

The renewable energy power module 11 generates electric energy with renewable energy and supplies it to the electric power storage device 20. The renewable energy power module 11 includes a renewable energy power generation unit 111 and a renewable energy power converter 112.

The renewable energy power generation unit 111 converts the renewable energy into electrical energy and supplies the electrical energy to the renewable energy power converter 112. [

For example, a photovoltaic power generation system may be employed as the renewable energy power generation unit 111. The solar power generation module converts solar energy into electric energy, including solar cell, solar cell module, and solar cell array. Here, the solar cell is the minimum unit for converting solar light into electrical energy, and is a kind of semiconductor that is pn-bonded to silicon on a 10 to 15 cm square plate. The output voltage of the solar cell is as low as about 0.5V to 0.6V. A plurality of solar cells are connected in series to manufacture a solar cell module. A plurality of solar cell modules are fixed to a certain frame, and these solar cell modules are combined again to fabricate a solar cell array. This solar cell array is installed in facilities such as history, or around the rail, and generates a predetermined voltage. In addition, the renewable energy power generation unit 111 may further include a wind power generator for generating electric power using wind power.

Here, the photovoltaic module may be manufactured in various forms adjacent to the railway facility and the railway facility. In addition, the wind turbine generator can generate electric energy by utilizing the heat wind generated when the railway vehicle is operated or by using the natural wind, and can be installed in the high speed section of the railway vehicle, the mountainous region, and the like. In this way, the photovoltaic generator and the wind turbine can be installed in various positions and methods in consideration of the railway operating environment and the natural environment. In addition, a piezoelectric device installed on the ground to produce power by pressure generated when a railway vehicle is operated can be included.

The regenerative energy power module 12 includes a regenerative energy power generation unit 121, a regenerative energy power converter 122, and a regenerative energy power adjuster 123.

The regenerative energy electric power generating unit 121 generates electric energy through the kinetic energy of the train when the train is driven or braked. When the accelerated train decelerates in the regenerative braking mode in order to make a stop while the vehicle is running, the regenerative energy power generation unit 121 operates as a generator and performs power generation braking, so that it can instantaneously produce large electric energy.

The regenerative energy power converter 122 converts the voltage of the power generated by the regenerative energy power generation unit 121 into the input voltage level of the power storage device 20 and supplies the converted voltage level to the power storage device 20 via the DC-Link bus .

[ In general, when an accelerated train decelerates by a regenerative braking method in order to make a stop while the vehicle is running, the electric motor performs power generation braking, and instantaneous large electric energy is generated. As a result, a large current is instantaneously applied to the power storage device 20, and as a result, the power storage device 20 may become unstable or its life may be deteriorated. The regenerative energy power adjuster 123 adjusts the current supplied from the regenerative energy power converter 122 appropriately according to the capacity of the power storage device 20 so that the power storage device 20 can be operated stably.

The charging switch 1231 is provided in a one-to-one correspondence with each of the charging modules 1232 to switch the power supplied to each of the charging modules 1232. The charging switch 1231 is switched in an appropriate number corresponding to the magnitude of the electric energy produced by the regenerative energy and the charging module 1232 selectively charges the electric energy according to the switching operation of each of the charging switches 1231 . For example, when the electrical energy produced by the regenerative energy is relatively small, a small number of charge switches 1231 are turned on. When the electrical energy produced by the regenerative energy is large, a relatively large number of charge switches 1231 ) Is turned on.

The voltage detection unit 1233 detects the voltage of the power supply produced by the regenerative energy power generation unit 121.

The current detection unit 1234 detects the current of the power supply produced by the regenerative energy power generation unit 121. [

A plurality of discharge switches 1235 are provided in a one-to-one correspondence with each of the charging modules 1232 so that the power supplied from each of the charging modules 1232 is switched and supplied to the power storage device 20, respectively.

The charge and discharge control unit 1236 controls each of the charge switches 1231 according to the voltage and current detected by the voltage detection unit 1233 and the current detection unit 1234 to charge the power to any one or more of the charge modules 1232 And adjusts the power supplied to the power storage device 20 by controlling each of the discharge switches 1235 according to the capacity of the power storage device 20.

The regenerative energy power regulator 123 temporarily charges the plurality of charging modules 1232 with the regenerative energy and supplies the power stored in the regenerative energy regenerating unit 1232 to the power storage unit 1232. [ By appropriately discharging the power according to the capacity of the apparatus 20, high electrical energy is supplied to the power storage device 20 to solve the problem that the power storage device 20 becomes unstable and its life is shortened.

The fuel cell power module 13 generates electrical energy based on the ionization reaction of the fuel cell and stores the electrical energy in the power storage device 20. The fuel cell power module 13 includes a fuel cell power generation unit 131 and a fuel cell power converter 132.

The fuel cell power generation unit 131 produces electric power based on the ionization reaction of the fuel cell. The fuel cell power generation unit 131 generates electric energy by supplying gaseous hydrogen or liquid hydrogen to the anode, supplying oxygen to the cathode, and ionizing the inside thereof.

The fuel cell power converter 132 converts the power generated by the fuel cell power generation unit 131 into an input voltage level of the power storage device 20 and supplies the converted power to the power storage device 20.

The power storage device 20 stores and manages the power supplied from the power generation device 10 through the DC-Link bus in cooperation with the DC-Link Bus, and controls the PCS (30).

The PCS (Power Conversion System) 30 is connected to the renewable energy power generation unit 111, the regenerative energy power generation unit 121 and the fuel cell power generation unit 131 to convert the DC power produced therefrom into AC power And supplies it directly to the historical facility 50. The PCS 30 supplies the power generated from the renewable energy power generation unit 111, the regenerative energy power generation unit 121 and the fuel cell power generation unit 131 to the integrated management server 40 in accordance with a control signal It is possible to positively cope with instantaneous high power such as peak power by directly supplying the power to the facility 50 without charging the device 20. [

The integrated management server 40 generally controls the historical power management apparatus according to an embodiment of the present invention. The integrated management server 40 monitors the amount of power stored in the power generation apparatus 10 and the load of the historical facility 50 in real time and outputs the power stored in the power storage apparatus 20 to the historical facility 50 Supply. Through this, the integrated management server 40 reduces the power consumption through the existing power system and reduces the peak load of the historical facility 50.

Referring to FIG. 3, the integrated management server 40 includes a database unit 41, a control server 42, and a load management unit 43.

The load management unit 43 monitors the load of the historical facility 50 in real time and adjusts the amount of power supplied from the power storage device 20 to the historic facility 50 in accordance with the control signal of the control server 42.

The control server 42 controls the load management unit 43 based on the load amount of the historical facility 50 detected by the load management unit 43 and the amount of power stored in the power storage device 20. [ In this case, the control server 42 charges the power storage device 20 when the load of the historical facility 50 is within the predetermined first reference range, and when the load of the historical facility 50 is within the predetermined second reference range The power storage device 20 is charged with power and the power of the power storage device 20 is discharged to supply the power to the historical facility 50. If the load of the historical facility 50 is within a predetermined third reference range The regenerative energy power generation unit 121 and the fuel cell production unit 131 of the power generation apparatus 10 are connected to the power generation apparatus 10 via the power generation apparatus 10, Converts the power generated through the PCS 30 into AC power, and then supplies the AC power directly to the historical facility 50. However, when the power storage device 20 is fully charged regardless of the load of the historical facility 50, the power generated from the power generation device 10 is converted into the AC power through the PCS 30, 50).

Here, the first reference range is a range in which the load of the historical facility 50 is very small, and the first reference range is a load range corresponding to the power consumption of the predetermined midnight time zone. Here, even when the load is within the first reference range, when the power storage device 20 is fully charged, the control server 42 converts the power generated from the power generation device 10 into AC power via the PCS 30 And can be supplied directly to the historic facility 50.

The second reference range is a load range in which the power consumption is lower than the third reference range and higher than the first reference range, and corresponds to a load range of the normal operation time period during which the historical facility 50 normally operates during day and night.

Finally, the third reference range is a load range within a preset ratio centered on the peak load, and the power rate is very high. When the usage amount of the air conditioner 51 or the like is suddenly increased This is the peak power load.

The database unit 41 stores the load of the historical facility 50 detected by the load management unit 43 and various programs necessary for operation and operation of the control server 42. [

That is, the renewable energy power module 11 generates electric energy through renewable energy (S12), and supplies the generated power to the power storage device 20. [

The regenerative energy power module 12 generates electrical energy through regenerative energy, and converts the generated power according to the input voltage level of the power storage device 20 (S14). In this case, the regenerative energy power module 12 charges the power to any one or more of the plurality of charging modules 1232 in accordance with the voltage and current of the power source generated through the regenerative energy, And supplies the adjusted power to the power storage device 20. The power storage device 20 may be connected to the power storage device 20 via a network.

In addition, the fuel cell power module 13 generates electric energy through the fuel cell (S16), respectively, and supplies the produced electric power to the electric power storage device 20.

Meanwhile, the power storage device 20 stores power supplied from the renewable energy power module 11, the regenerative energy power module 12, and the fuel cell power module 13 (S20).

In this way, as the electric power is charged in the electric power storage device 20, the integrated management server 40 can control the amount of electric power charged in the electric power storage device 20 and the load of the electric power storage device 20 And supplies power to the historical facility 50 (S30).

That is, the control server 42 determines whether the load of the historical facility 50 is within a predetermined first reference range (S320).

If it is determined in step S320 that the load of the historical facility 50 is within the first reference range, the control server 42 controls the power generation apparatus 10 to charge the power storage apparatus 20 (S330).

On the other hand, if it is determined in step S320 that the load of the historical facility 50 is not within the first reference range, the control server 42 determines that the load of the historical facility 50 is within the predetermined second reference range (S340).

As a result of the determination in step S340, if the load of the historical facility 50 is within the second reference range, the control server 42 charges power to the power storage device 20, The power source is discharged and converted into AC power through the PCS 30, and then supplied to the historical facility 50 (S350).

On the other hand, if it is determined in step S340 that the load of the historical facility 50 is not included within the second reference range, the control server 42 determines that the load of the historical facility 50 is within the predetermined third reference range (S360).

As a result of the determination in step S360, if the load of the historical facility 50 is within the third reference range, the control server 42 discharges the power of the power storage device 20 and supplies it to the AC power supply through the PCS 30 And supplies it to the historical facility 50 and then through the renewable energy power generation unit 111, the regenerative energy power generation unit 121 and the fuel cell power generation unit 131 of the power generation apparatus 10 DC power supplied through the DC-Link bus is converted into AC power through the PCS 60, and then supplied directly to the historical facility 50 (S370).
