Description

[0001] MONITORING SYSTEM FOR SOLAR POWER PLANT [0002]

Generally, a power generating apparatus generating electricity can be classified into thermal power generation using fossil fuel such as petroleum or coal and solar power, nuclear power, hydroelectric power, tidal power, and wind power generation depending on the energy source used.

Among these power generation devices, a power generation device using nuclear power has an advantage that it can generate electricity at a lower cost than thermal power generation, but installation is limited due to environmental pollution due to radioactivity and harmfulness of human body. Moreover, recently, facility investment has not been smoothly carried out due to the disposal of nuclear waste generated after electricity production.

In the case of thermal power generation, fossil fuels such as coal and petroleum are used. These generation fuels not only discharge substances that pollute the environment when electricity is generated, but also have high fuel costs. Moreover, recently, oil prices have been rising due to a decrease in resource reserves, and as a result, power generation costs have increased, and it is possible to replace them, and development of clean energy that does not generate substances that pollute the environment is required.

In addition, recently, regulations are being implemented to curb the emission of carbon dioxide globally, and it is required to develop a new power generation device that does not emit carbon dioxide.

As such, there is no emission of carbon dioxide, and a power generation device using solar energy is a typical power generation device using clean energy. Recently, the development and installation costs of technology have been reduced, and the spread has been spreading.

However, in the case of the conventional photovoltaic power generation apparatus, since a plurality of solar panels are generally clustered to form one large flat plate, strong winds such as typhoons cause fatal problems that can not withstand wind loads and are damaged. And the second damage such as inducing other facilities or personnel accidents in the vicinity along with the damage occurred frequently.

Therefore, it was necessary to develop a stable facility capable of minimizing damage caused by wind loads, and to develop a monitoring system that can safely manage these facilities.

As shown, the monitoring system for the photovoltaic power generation system, which is a management target of the monitoring system according to the embodiment of the present invention, can centrally manage the photovoltaic power generation devices installed in a wide range of the monitoring areas A to H In addition to monitoring the status of the equipment due to wind load, if necessary, generating alarms or calculating step-by-step risks, as well as directly intervening to operate some components of the PV system or dispatch managers So that the damage caused by wind load can be minimized and safety can be ensured.

Hereinafter, a configuration of a monitoring system for a photovoltaic power generation system to be managed by the monitoring system according to the embodiment of the present invention will be described.

FIG. 2 is a configuration diagram of a monitoring system according to an embodiment of the present invention, FIG. 3 is a reference view showing a solar panel array region divided into a plurality of monitoring regions in a monitoring system according to an embodiment of the present invention, Is a reference view showing a monitoring screen displayed on a display in a monitoring system according to an embodiment of the present invention. 5 to 7 are a front perspective view, a rear perspective view, and a side view of the photovoltaic power generation apparatus, which is a management object of the monitoring system according to the embodiment of the present invention.

As shown in FIG. 3, the monitoring system according to the embodiment of the present invention divides and sets the solar panel array 110 of the solar power generation apparatus into a plurality of detailed monitoring areas 1 to 18, The risk of loss of the solar panel in the regions 1 to 18 and the risk of leaving the post frame 120c can be managed. To this end, an upper vibration sensor S2 and a lower vibration sensor S1, an anemometer S3, a weather vane S4, a camera S5, and the like are provided for detecting the state of the solar power generation device in real time around the controller 180. [ A first displacement sensor 115a and a second displacement sensor 115b and is provided with a display 191 and an alarm device 192 for indicating the state being sensed. And the driving force providing member 140 of the photovoltaic power generation apparatus.

Hereinafter, a configuration of a monitoring system for a photovoltaic power generation apparatus according to an embodiment of the present invention will be described in detail with reference to the above-described components.

The upper vibration sensor S2 is useful for calculating the risk of loss of the solar panel by measuring the vibration value applied to the solar panel due to the influence of wind caused by the back wind. Therefore, the controller 180 controls the solar panel array 110 (110) in consideration of the area, the installation angle and the direction of the solar panel array 110 based on the wind speed and the wind direction measured by the anemometer (S3) And calculates the risk of loss of the solar panel due to the wind load based on the vibration value measured by the upper vibration sensor S2 installed in each monitoring area on the basis of the calculated wind load. If the vibration value measured by the upper vibration sensor S2 is lower than the reference value by setting a higher reference value in consideration of the basic vibration value that may be generated at the upper end portion of the post frame 120c due to the calculated wind load, The risk of loss is shifted to the safety level, warning level if it is above the first threshold level, and risk level if it is above the second threshold level.

When the risk of the solar panel loss is a warning level, the controller 180 operates the driving force providing member 140 to open the first open solar panel 110b to the second open solar panel 110c, To reduce the resistance by wind loads and to operate as a safety step. At this time, instead of collectively opening the plurality of second open-type solar panels 110c, the risk of the solar panel loss may be differentiated by opening the second open-type solar battery board 110c located closest to the surveillance region reaching the warning step Control. 3, reference numeral A120c denotes an area where the post frame 120c is provided, reference numeral A110b denotes an area where the first open type solar panel is installed, reference symbol A110c denotes an area where the second open type solar panel is installed . (The specific configuration of the photovoltaic apparatus to be managed by the monitoring system according to the embodiment of the present invention including the first open solar battery board 110b and the second open solar battery board 110c will be described in detail later )

Also, whenever the risk of the solar panel loss is upgraded to the warning stage and the danger stage, the display 191 is displayed with different colors in the corresponding surveillance regions, as shown in FIG. For reference, in the figure, the surveillance area 6 and the surveillance area 11 are marked as having reached the warning step and the dangerous step.

The lower vibration sensor S1 is useful for calculating the risk of departing the post frame 120c with respect to the ground for various reasons such as an effect of wind load, an earthquake, an age of the apparatus, and the like. Therefore, the controller 180 calculates the risk of leaving the post frame 120c with respect to the ground based on the vibration value measured by the lower vibration sensor S1. If the vibration value measured by the lower vibration sensor S1 is lower than the reference value, a higher value is set as a reference value considering the basic vibration value that may be generated at the lower end portion of the post frame 120c due to the calculated wind load, The risk of escape of the post frame 120c to the safety stage is raised to a warning stage if the first threshold value is exceeded, and to the danger stage if the second threshold value is exceeded.

As shown in FIG. 4, when the risk of leaving the post frame 120c is raised to the warning step and the dangerous step, the color of the corresponding display area is displayed on the display 191 do. For reference, in the figure, the surveillance area 10 indicates that the risk of escape of the post frame 120c, as well as the risk of the solar panel losing, has entered the warning stage and the danger stage.

The anemometer (S3) and the weather vane (S4) are installed near the solar panel array (110) to measure the wind speed and the wind direction. The anemometer S3 and the weather vane S4 are preferably installed on the left side and the postal side of the solar panel array 110 respectively and the measured wind speed and direction are transmitted to the controller 180 in real time. It is noted that what is of interest in the embodiment of the present invention is that the front part of the solar panel array 110 blows from the rear of the solar panel array 110 rather than the front wind, It can be said to be the cause of the rear wind. The controller 180 controls the wind speed measured by the anemometer S3 and the area of the solar panel array 110 included in the solar panel array 110 when the wind detected by the wind vane S4 is the rear wind, And calculates a wind load per unit area acting on the solar panel array 110.

5, the camera S5 may be installed on one side of the edge of the solar panel array 110 or may be installed near the front side to visually check the state of the solar panel array 110 through the display 191 . Such a camera S5 helps to visually confirm the operating state of the first open solar panel 110b and the second open solar panel 110c and the loss state of the solar panel.

The first displacement sensor 115a and the second displacement sensor 115b detect the opening of the first and second open solar panels 110b and 110c, respectively. For this purpose, the first displacement sensor 115a and the second displacement sensor 115b may be a magnetic sensor or a touch sensor installed near the first and second open solar panels 110b and 110c, And a vision installed on the lower side of the solar panel array 110 may be utilized.

The display 191 is installed in a management room having an administrator and divided monitoring areas 1 to 18 of the solar panel array 110 belonging to each monitoring area A to H are basically displayed, The risk of loss of the battery panel and the risk of leaving the post frame 120c are displayed in real time in different colors in different steps. Also, a screen shot by the camera S5 in real time is displayed when the operator selects it, or displayed at all times by screen division.

It is preferable that the alarm device 192 is provided with a siren and an alarm that can be visually recognized by the manager if the risk of loss of the solar panel and the risk of leaving the post frame 120c rise from the safety stage to the warning stage and the danger stage Do. The sirens and alarms may be installed one by one in the monitoring area A to H in which the solar panel array 110 is installed together with the management room where the manager is located.

Meanwhile, the photovoltaic power generation apparatus to be a target of the monitoring system according to the embodiment of the present invention is called as a way to effectively reduce the resistance to wind load when a strong wind such as a strong typhoon blows and receives a wind load exceeding a certain level The lower part of the array can be opened to allow the wind to pass, thereby preventing damages caused by strong winds and minimizing the design load considering the wind load, thereby ultimately reducing the installation cost. .

Hereinafter, a photovoltaic generation apparatus to be a monitoring target of a monitoring system according to an embodiment of the present invention will be described.

FIG. 8 and FIG. 9 are rear bottom perspective views for explaining the open structure of the first open solar panel and the second open solar panel in the photovoltaic device, which is a management object of the monitoring system according to the embodiment of the present invention. 10 and 11 are a series of reference side views for explaining the opening operation of the first open solar panel and the second open solar panel in the photovoltaic device according to the embodiment of the present invention.

As shown in the figure, the photovoltaic generation apparatus to be managed by the monitoring system according to the embodiment of the present invention includes a solar panel array 110, frame assemblies 120a, 120b, and 120c that support the solar panel array 110, And an anchor module 160 having an elastic supporting member 130, a driving force providing member 140, a shock absorber shoe 150, and a bending anchor 162.

Such a photovoltaic power generation apparatus is configured such that, when a certain amount of wind load is applied to the solar panel array 110 as well as the stationary solar panel 110a due to the wind blowing from the rear surface, the lower end portion is actively lifted without any additional energy source, The first open solar cell plate 110b and the second open solar cell plate 110b are connected to each other by a driving force through the control of the controller 180 when the opening of the first open type solar battery board 110b is insufficient, And a second type solar cell module 110c which is a combination of the first and second solar cell modules 110c.

According to this configuration, when a strong wind load is applied from the rear, the first and second open solar panels 110b and 110c are sequentially opened as shown in FIGS. 10 and 11, The post frame 120c can be more stably fixed by the original configuration in which the bending anchor 162 capable of bending operation is embedded in a deeper and wider extended form relative to the ground, And the lower end fixing point of the post frame 120c, which is a weak part of this intensively acting structure, is structurally strengthened.

With such a configuration, it is possible to effectively suppress the problem that the solar panel can not withstand the wind load and is detached from the frame assembly, or the post frame 120c is pulled out from the ground, causing a great damage.

Hereinafter, a photovoltaic power generation apparatus, which is a management target of a monitoring system according to an embodiment of the present invention, will be described in more detail with reference to the respective components.

The solar cell array 110 includes a first open solar cell plate 110b and a second open solar cell plate 110c together with the stationary solar cell plate 110a as described above.

Here, the first open-type solar panel 110b is actively opened by itself when a certain amount of wind load acts on the rear wind, thereby primarily reducing wind resistance. To this end, the first open solar cell plate 110b occupies at least a part of the solar cell plates disposed in the lower first row of the solar cell array 110, preferably substantially all or almost entirely, as shown in FIG. 5, And the rotation shaft is supported by the elastic support member 130 and is provided with an elastic force. Here, the elastic support member 130 allows the first open solar panel 110b to rotate about the upper end rotational axis when a certain amount of wind load acts on the first open solar panel 110b, and then returns to the original position when the wind load disappears. The first open-type solar panel 110b is actively rotated and opened by itself when a load equal to or greater than a certain level is applied by the rear wind so that the rear wind can escape forward as shown in FIG. 10, Thereby forming a flow path. When the flow path is formed at the lowermost end of the solar panel array 110, the amount of wind acting on the rear surface of the solar panel array 110 is drained through the flow path, and the resistance due to the wind is also reduced.

The second open solar cell plate 110c occupies a part of the solar cell plates arranged in the upper row than the lower one row of the solar cell array 110 and is not rotated and opened by itself unlike the first open type solar cell plate 110b And is opened by receiving driving force from the driving force providing member 140. Like the first open solar panel 110b, the second open solar cell plate 110c is configured to rotate about the rotation axis 144 installed on the rear surface of the upper end so that the lower end thereof can be heard and the rear wind can pass therethrough. 15, the second open-type solar panel 110c is difficult to handle by opening the first open-type solar panel 110b due to a strong wind load acting in the rear direction, that is, The driving force is provided through the control of the controller 180 and is further opened.

The elastic supporting member 130 rotatably supports the upper end of the first open solar panel 110b and permits rotation only when a wind load of a predetermined level or higher is applied. When the wind load over a certain level disappears, the elastic supporting member 130 rotates in the opposite direction, To provide a resilient force. Hereinafter, the configuration of the elastic supporting member 130 will be described in detail.

FIG. 12 is a perspective view for explaining a configuration of an elastic supporting member in a solar power generation apparatus to be managed by a monitoring system according to an embodiment of the present invention, FIG. 13 is a perspective view of a solar power generation Figs. 14 and 15 are a series of explanatory views for explaining the operation and action of the elastic supporting member in the photovoltaic device according to the embodiment of the present invention. Fig. Fig.

As shown in the figure, the elastic supporting member 130 rotatably couples the first open solar panel 110b with respect to the longitudinal frame 120b, and gradually increases in proportion to the angle of its rotation By providing a resistance, it is possible to suppress excessive rotation of the first open solar panel 110b. The elastic support member 130 includes a fixed cam 131, a rotation cam 132, a guide rod 133, and a compression spring 134.

 The fixed cam 131 is fixed to the longitudinal frame 120b and has a profile formed by periodically forming a top dead center point 131a and a bottom dead center point 131d and an inclined line 131c therebetween along the circumferential direction Respectively. The fixed cam 131 is provided with a through hole 131d so that the guide rod 133 can pass through the fixed cam 131 along the axial direction.

The rotation cam 132 rotates when the first open solar cell plate 110b rotates in a state of being in contact with the fixed cam 131 and is rotated with respect to the interaction with the fixed cam 131 And converts the rotational force into a linear force. To this end, the rotation cam 132 is formed with a top dead center point 132a and a bottom dead center point 132b, and an inclined line 132c therebetween periodically along the circumferential direction to correspond to the profile of the fixed cam 131 And a contact profile. The rotation cam 132 is coupled to the first open solar panel 110b to be movable forward and backward while being rotated together with the first open solar panel 110b. The rotation cam 132 is provided with a through hole 132d which is penetrated by the guide rod 133 and is slidable in a sliding groove 133a formed along the longitudinal direction on the outer circumferential surface of the guide rod 133 And a sliding protrusion 132e to be fitted.

The compression spring 134 is positioned at the rear end of the rotation cam 132 to elastically support the rear end of the rotation cam 132 and is inserted through the guide rod 133. When the compression spring 134 is in a state of being penetrated by the guide rod 133, the compression spring 134 is excessively bent to prevent it from being projected or separated from the side.

The guide rod 133 is installed so as to penetrate the fixed cam 131, the rotation cam 132, and the compression spring 134 in order along the axial direction. At this time, the guide rod 133 is idled without interfering with the fixed cam 131, but the rotation cam 132 is rotated by the engagement between the sliding groove 133a and the sliding protrusion 132d, ), But does not allow relative rotational motion but constrains it. According to such a configuration, the guide rod 133 is guided so as to stably operate when the rotation cam 132 moves back and forth. Reference numeral 136, which is not referred to as a reference, is a fixed portion of the guide rod 133 extending from the guide rod 133 and joined to the rotation axis of the first open solar panel 110b.

According to the structure of the elastic support member 130, when a wind force is applied to the first open solar cell plate 110b from the rear and the first open solar cell plate 110b is rotated about the rotation axis, The first open solar cell plate 110b and the rotation cam 132 and the guide rod 133 coupled to the rotation axis thereof rotate together with the rotation of the rotation shaft 132. As a result, And the top dead center point 132a of the rotating cam 132 is brought out of contact with the bottom dead center 131b of the fixed cam 131 due to the rotation of the rotating cam 132, (131a) of the fixed cam (131). As the angle of rotation of the first open solar panel 110b increases, the degree of retraction increases and the degree to which the compression spring 134 is compressed becomes larger as the rotational angle of the first open solar panel 110b increases. . Accordingly, the compression spring 134 has a greater resilient supporting force and is strongly resilient against the retraction of the rotation cam 132, and the resistance thereof is transmitted as it is, so that the first open solar cell plate 110b is moved forward Thereby suppressing rotation. Thereafter, when the wind load disappears, the rotation cam 132 and the first open solar panel 110b rotate in the opposite direction and return to the original position due to the elastic support force of the compression spring 134. [

Further, the elastic support member 130 is formed so that a trigger groove 131f formed in the bottom dead center of the fixed cam 131 is formed, and that the top end of the rotation cam 132 is seated in correspondence with the trigger groove 131f The protruded trigger protrusion 132f is formed. As a result, the first open type solar battery board 110b tends to maintain the closed state unless a wind load of more than a certain level is applied thereto, so that the problem of frequent opening or unstable shaking due to a weak wind load can be solved. Here, the trigger groove 131f may be formed at any position of the profile, not limited to the bottom dead center of the fixed cam 131, and even in the case of the trigger projection 132f, It can be formed at any position of the profile without being formed only at the point.

The driving force providing member 140 serves to provide a driving force to the second open solar panel 110c as described above. To this end, the driving force providing member 140 is installed in the longitudinal frame 120b supporting the second open solar cell plate 110c from the lower side to provide a driving force for rotating the upper end of the second open solar panel 110c A driving motor 141 and a reduction gear assembly 142 installed between the driving motor 141 and the second open solar panel 110c to reduce the rotational speed of the driving motor 141. [ Here, the output shaft of the reduction gear assembly 142 is connected to the rotation shaft 144 of the second open solar panel 110c. The driving force providing member 140 is controlled by the controller 180 and operates.

8 and 9, the buffer shoe 150 is installed to support the first and second open solar panels 110b and 110c, respectively. The shock absorber 150 is hinged to one end of the solar panel and the other end of the shock absorber 150 is hinged to a buffer block 151 provided on the ground. The shoe bar 150 restricts the first open solar cell plate 110b and the second open type solar cell plate 110c from rotating forward to an excessive degree and the first open solar cell plate 110b and the second open type solar cell plate 110c, When the solar panel 110c suddenly rotates, it can instantaneously provide a reaction force so as to be able to cope with impact and breakage which may be caused by abrupt rotation. The shock absorber 150 is effective when both the first open solar cell plate 110b and the second open solar cell plate 110c are opened forward and in both directions when they are opened and closed in the original state, Absorbed. Meanwhile, although the shock absorber 150 is mainly fixed on the ground, the shock absorber 150 may be a small shock absorber 150 and may be supported by the transverse frame 120a or the longitudinal frame 120b. . ≪ / RTI >

The shock absorber block 151 hinged to the other end of the shock absorber 150 is installed on the ground and supports the other end of the shock absorber 150, The vibration of the first open solar cell plate 110b transmitted through the first open solar cell plate 110b is attenuated.

The anchor module 160 includes a flange 161 joined to the lower end of the post frame, a bending anchor 162, a bolt 163, and a vibration blocking member 164. First, the bent anchor 162 functions to stably fix the lower end of each of the post frames 120c on the ground. In particular, the bending anchor 162 has a unique structure that can be folded as shown in FIG. 13, so that it is embedded deeper than the width of the base block 175. Hereinafter, the original configuration of such a breakable anchor 162 will be described in more detail below.

FIG. 16 is a perspective view for explaining the configuration of a breakable anchor in the solar power generation apparatus to be managed by the monitoring system according to the embodiment of the present invention, FIG. 17 is a perspective view of the solar power generation FIG. 18 is a perspective view for explaining the configuration of a breakable anchor vibration blocking member in a photovoltaic power generation system to be managed by the monitoring system according to the embodiment of the present invention. FIG.

As shown in the drawings, in the embodiment of the present invention, the bending-type anchor 162 is formed of a plurality of bodies which are coupled to each other in a pin-like manner so as to be able to bend. The bent anchor 162 includes a first body 162a fastened to the flange at the lower end of the post frame 120c by bolts and a second body 162a which is pivotally coupled to the lower end of the first body 162a, And a third body 162c rotatably connected to the lower end of the second body 162b.

Here, the anchor 162 may have a variety of deformations in the number and type of connection of the body. For example, the anchor 162 may be formed of five link sections having a rectangular column shape instead of a cylinder.

As shown in FIG. 17, the bent anchor 162 is embedded in the ground surface of the base block 175 so as to be wider than the base block 175, And the supporting force against the ground can be increased. As a result, the post frame 120c is more stably fixed, and the lower end fixing point of the post frame 120c, which is a fragile portion in which the wind load is concentrated, is structurally greatly strengthened. Accordingly, it is possible to effectively prevent the problem that the solar panel can not withstand the wind load and is dislodged from the frame assembly or the post frame 120c is pulled out from the ground, thereby causing great damage. In addition, the bent anchor 162 can easily prevent the reinforcing bars 171 and 172, which are interfered with the bed portion provided on the floor (upper floor of a lower structure such as a normal building), by the folding action, There is also an advantage that the adhesion can be further strengthened. In addition, although not shown in the drawings, the second body 162b may be inclined to be widened toward the lower side, and the third body 162c positioned at the lower end may be inclined downwardly as opposed to the second body 162b, The third body 162c can firmly hold the concrete and resist more strongly when the negative reaction force is generated. Accordingly, it is possible to effectively prevent the problem that the solar panel can not withstand the wind load and is dislodged from the frame assembly or the post frame 120c is pulled out from the ground, thereby causing great damage.

Further, when the bent anchor 162 is installed on a bed portion provided on a floor (upper floor of a lower structure such as a normal building), the interference reinforcing bars 171 and 172 can be easily avoided by the folding action, It is possible to further enhance the adhesive force of the adhesive.

A bolt 163 is fastened to the upper end of the anchor 162 embedded in the base block 175. A vibration transmitted to the bolt 163 through the post frame 120c is transmitted to the lower end of the post frame 120c. And an anti-vibration member 164 for interception is provided. The vibration isolating member 164 includes a body 164a made of a highly damped rubber material effective to attenuate vibrations and accommodates the lower portion of the head of the bolt 163 while passing through the body of the bolt 163 And an accommodating portion 164b for enclosing it. The inner circumferential surface of the receiving portion 164b is formed of triangular protrusions 164c continuously formed along the circumferential direction, so that the contact force of the head portion of the bolt 163 can be enhanced.

The vibration shielding member 164 of this configuration effectively works to prevent the problem of loosening the bolt 163 due to the vibration transmitted from the post frame 120c and the problem of weakening the anchoring force of the anchor 162 to the ground .
