The solar cell module may include a front-side solar cell module, a south solar cell module, and a west solar cell module, wherein the sensing unit is disposed inside the circular core, and an input wire from the solar cell array is connected to the cylindrical bus bar. A solar cell module and a solar cell module adjacent thereto are disposed opposite to each other in a plan view and connect the positive and negative connectors in a manner of connecting the connection wiring layers located on the same horizontal line. The noise removing unit includes a choke coil and is connected to only one inverter.

A diagram 5 showing a connection relationship between a noise removal unit and an inverter in a photovoltaic power generation system according to an embodiment of the present invention. It is 6 a diagram illustrating a photovoltaic power generation system according to another embodiment of the present invention. The embodiments are described below to explain the present invention by referring to the figures. It is 2 to be noted that reference 6 is also made to FIGS. A solar power generation system according to an embodiment of the 100 present invention includes a solar cell array 200, an arc detection, 300 and a blocking unit 400, a wiring blocking unit, an inverter, and a 500 noise removal unit (noise eliminator). , The present invention will be described in detail with reference to the above components. The solar cell array may 100 include a cradle for fixing a plurality of solar 110 cell modules 110 - 170 (170 a '-' ') to a ground or structure of a plurality of 110 - 170 solar 110 170 cell modules (a, ' - '), and a solar cell module (e.g. ' - '). A plurality of solar 110 - 170 cells 110, 170 which are capable of converting solar energy into electric energy as a basic element of the 110 solar cell, 110 - 170 includes a 170 frame having various cross-sectional shapes for protecting the solar 110 - 170 110 cells inside the solar cell modules (a, '-' 170). For this series connection, the rear surface of 110 - 170 each 110 of 170 the solar 110 - 170 cell 110 modules 170 (a, the '-' ') is 101 provided with a connection wiring box (a connection wiring that is used for stably 101 connecting the 115 electricity 175 produced by 113 - 173 the 113 solar 173 cell modules (a, ' 115 - 175 - ') to each other. In the present invention, a 110 - 170 solar cell module is placed in a reverse direction with respect to the solar cell module adjacent thereto, and the plus and minus connectors are connected to each other through the same horizontal 110 line 170. That is to say 2, in the 1 case of the 110 first solar cell 3 module, the 130 first solar cell 5 module, the 150 first solar cell 7, the first 170 solar cell, and the second 101 solar cell, respectively, the 2 first and second 120 solar cell modules 4 and the first 140 and the second 6 solar cell modules 160 may be disposed at the lower 101 part of the first and second solar cell modules, respectively, and the first and second solar cell modules (the first and the second solar cell modules in the first and the second solar cell modules, respectively, respectively. Due to this arrangement structure, 1 the first and 110 the negative connectors 1 of the first 113 and second solar 3 cell modules are 130 combined with the 3 first and the 135 negative connectors of the first 1 and second solar 110 cell modules, 1 respectively, and 115 the first and 2 the negative connectors 120 of the first 2 and second solar 123 cell modules are connected to 2 the first and 120 the negative connectors 2 of the first 125 and second solar 4 cell modules, 140 respectively, and 4 the first and 143 the second connector parts of the first 100 and second solar cell modules are connected to each other in series. An arrangement structure of a connector is provided to prevent a parallel arc from being generated by connecting connectors to each other. Further, in the present invention, a 100 total length of a minus connector (113 - 173 a 173 113 ′-b′ ') included in the solar cell array and plus the plus 115 - 175 115-connector 175 (e.g. ' - ') may be configured in the same manner as in the present invention. As described above, by identically 100 constructing the total length of the minus 113 connectors 113 - 173 (a, '173 -' - '') and the plus-115 - 175 connector '175 - (' - ') in 115 the solar cell array, it is possible to prevent an arc generation due to an imbalance in resistance in the negative connector and the positive connector even if the minus connector and the positive connector are aged. In addition, the minus connectors are connected to each 113 - 173 other. Since 113 the current non 173-uniformity problem between the positive and the 175 115 - 175 positive (+) - and the positive (+) - and the positive-connector 115 (e.g. '-') is eliminated together, accurate arc detection can be performed in 213 the arc detection circuit unit described later, which will be described later. The arc detection and shut-200 off unit may be connected to 100 any one of a minus wiring (a) or a plus line (b) from the solar 100 cell array (S) by detecting an arc generated in the solar cell array and blocking a flow of a 210 current 230 250 270. To detect the frequency of the direct-210 3 current electricity introduced from the solar cell array 100, the arc detection circuit (S) is configured to detect an arc through detection 213 of a specific frequency 215b of the direct-current 215a electricity introduced from the solar cell array, and to pass only a 215 specific frequency of the detected 217 frequency 215 (i.e. the arc-generating frequency). In addition, in the embodiment of the present 210 invention, the power supply is generally supplied from an 4 electric power source in order to drive the 10 arc 20 detection 30 unit in accordance with the embodiment of the present invention. This is to reduce the cost of 24 operating a bar system by using a single-time power source, since an unnecessary power waste is generated. As shown 4 in the figure, each of the solar cell 10 modules 20, 30 the solar cell module, and the solar cell module may be installed to face the 10 east, the left, and the front, respectively, to 210 make the arc detection portion S operate in an operating standby 30 state 210. , The present invention enables efficient use of the 200 system by operating only in a state in which the arc detection and blocking unit (S) floats. As such, the electricity produced by the 20 separate solar cell modules (10 such as the 30 solar-cell modules, e.g. the light-emitting diode and 213 the light-emitting diode may be used as a driving power source of the 213a arc detection unit (M) through 210 the power supply unit (a) provided in the arc detection circuit unit (A). As shown 3 in the figure, the sensing unit may 215 be configured such that a 215a cylindrical bus bar is inserted 219 into an inside of a circular core, and an input wire c from the 100 solar cell array (S) is connected to 219 a cylindrical bus bar (PCB). When a short-230 circuit occurs in the case that the short 210-circuit occurs, it is connected to the output 213 wiring (d) 210 of the cylindrical bus bar of the arc detection circuit unit (A) 219. As a configuration for 250 interrupting the current flow of 300 the positive wiring b, which is connected to the molded case circuit breaker, the electronic 210 switch may be activated by receiving an arc detection signal of the arc detection unit (S). The following describes an operation process of 200 the arc detection and cutoff unit. When the frequency of the direct-100 current electricity coming from the 215 solar cell array is sensed by the sensing unit, only a specific frequency, that is, the 40 - 100 kHz arc generation frequency, passes through 217 the band-pass filter, and the 213 arc detection circuit unit is determined to have an arc when the arc generation frequency is input. After that, the arc detection circuit unit (213 IC) blocks the current flow of the plus wire 250 (b) connected to the wiring blocking unit (S) by immediately opening the electronic switch 300 (½) in the signal line. The molded case circuit breaker 300 according to an embodiment of 100 the present invention may be electrically connected 200 to the solar cell array and the arc detection and cut-off units, and the circuit breaker according to the embodiment of the present invention. When an overload current flows or a short circuit occurs in the internal circuit, current is interrupted. A maximum power point 400 tracking 100 (MPPT) control technology is applied in accordance with the variation of the element in order to 110 - 170 obtain 110 the 170 maximum power from the solar cell module, as described above 400. However, if the maximum power point tracking (MPPT) control technology is applied to the inverter (400 the MPPT) control technology, high-speed switching is repeatedly performed in order to find the maximum power point. The noise may affect the 400 arc detection and disconnection 200 (DC) that is electrically connected to the inverter, making accurate arc detection difficult. , In order to improve the accuracy of the arc detection by blocking the inflow 400 of noise generated from the inverter using the maximum power point tracking (MPPT) control 200 technology as described above, an arc detection and a noise reduction unit may be provided between the arc detection and 400 shut-off unit (DC) and 500 the inverter (M). It is preferable that the noise removing unit (500 M) consists 5 of a choke coil, and is 400 connected to only a single inverter as shown in FIG. This is because the characteristic of 500 the noise coming from the several 400 inverters is different due to the characteristic 400 of each of the inverters, and 400 it is difficult to effectively remove the noise in the 500 noise removing unit by the characteristic of each of the inverters in the case of being connected to the plurality of inverters. To another embodiment of the present invention, it 6 is possible to detect the accurate arc even if 100 a 100 large-100 capacity inverter is used even when a plurality of solar cells are installed in the case 500 of a plurality of 400 solar cell arrays (a, '', '') and is provided with only one noise-eliminating unit. However, in this case, since a 100 large 100 current flows 100 in a wiring in a relation in which a plurality of solar cell arrays are provided, a large current 601 flows in the wiring, and the minus 602 bus bars and the positive wiring are collected to collect the negative wiring of each of the solar cell arrays. At this time, only one of 500 the minus wirings and the plus wirings is sufficient to remove the noise. This is because the wiring of each solar cell array is 601 connected in series with the negative bus bar 602 (+) and the positive bus bar (S) in series. This makes it possible to configure 100 the 100 system very 100 economically in that it is only one of the arc 200 detection and the blocking units, even if there are a plurality of solar cell arrays (a ',', '') installed therein. As described above, according to the present invention, 100 when a specific frequency capable of determining 210 whether or not an arc 219 is generated in the process of flowing through the cylindrical busbars of the arc 250 detection unit (the arc 200 detection units, the arc detection and the detection of the specific 500 frequency can be performed by 400 removing the noise introduced from the inverter using the arc detection unit (S). It will be understood by those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions.
