Photovoltaic management device

Abstract

To solve the problem that surveillance cameras at the location of photovoltaic devices at night are insufficiently effective in preventing theft because they overlook or delay the detection of thieves.SOLUTION: In order to detect thieves at nighttime and reduce theft at the location of a photovoltaic device, a photovoltaic device illuminates the photovoltaic panels, measures the amount of electricity generated, and immediately detects the intrusion of people by cutting power cables, activates red lights and alarms, and dispatches a security company to the location to secure the thief and prevent theft when the amount of electricity generated decreases below a certain level.SELECTED DRAWING: Figure 4

Description

[Technical field]

[0001] The present invention relates to a device that reduces theft of electric cables and solar panels of a solar power generation device and has a high theft deterrent effect. [Background technology]

[0002] Ground-mounted solar power plants, when they become large-scale, are often located in remote areas. Therefore, they are hard to see and are not monitored properly. Especially at night, when no electricity is generated and no current flows, the cables are cut and the solar panels and cables are stolen. Therefore, crime prevention measures such as security cameras are being implemented.

[0003] However, because security cameras are used at night, they are ineffective at preventing theft because they overlook or delay detection of the thief. If the equipment is stolen, the customer will suffer double damage, not only the loss of the equipment (assets) but also the loss of power generation, which significantly extends the payback period for the investment.

[0006] In order to detect a thief reliably and quickly, the present invention predicts the presence of a thief by detecting the act of cutting electric cables, which a thief will certainly do at an early stage after entering an area where a solar power generation system is installed, as a discrimination signal, and issues a warning display or signal, which allows the monitoring management company or security company to immediately become aware of the situation, and the security company can then quickly dispatch to the power generation system installation site, thereby preventing theft by apprehending the thief. Effect of the Invention

[0007] According to the present invention, the thief can be found quickly and reliably, and the theft can be reduced. As this device that can reliably capture thieves becomes more widespread, the theft deterrent effect will increase. [Brief description of the drawings]

[0009] Details will be described below with reference to the drawings. EXAMPLES

[0010] Fig. 1 is a block diagram showing an overview of a photovoltaic power generation management device according to an embodiment of the present invention. Electricity generated by a lighting device (1) from multiple photovoltaic power generation panels (2) is collected by a current collector (3), some of which is charged and discharged through a storage battery (4), and converted from direct current to alternating current by a power conditioner (5). The amount of power generated can be confirmed on a display device (6). The data is also measured by a data measuring device (7). A manager or a security company (8) monitors from a remote location. A red light (10) and an alarm device (11) are activated based on the data from the data measuring device (7). The generated alternating current electricity flows into a power transmission line (9).

[0011] 2 is a diagram showing an overview of a lighting device in a photovoltaic power generation management device according to an embodiment of the present invention. The lighting device (1) is installed so that light falls on a photovoltaic power generation panel (2).

[0012] FIG. 3 is a diagram showing an overview of a lighting device in a solar power generation management device according to an embodiment of the present invention, similar to FIG. 2, but shows a different form from that shown in FIG. 2, that is, a lighting device (1a) that is installed so as to illuminate a wide area and also to serve as security lighting, so that light also falls on a solar power generation panel (2).

[0013] Hereinafter, the embodiment of the present invention will be described in detail with reference to the flowchart of FIG. explain.

[0014] It judges whether it is day or night (S1), and if it is night and no power is being generated, it will operate in mode 2, crime prevention power generation. As a result of (S2), when the lighting device (1) facing the solar power generation panel (2) is turned on, solar power generation begins due to the illumination light, and a certain amount of power generation is measured by the data measurement device (7).

[0015] An administrator and a security company (8) monitor data such as the amount of power generated from a remote location near the power generation equipment.

[0016] While measuring the change in power generation in mode 2 (S3), the amount of power generated by lighting is constant, so this amount of power generation is set as the lower limit. If data is detected showing a decrease in power generation (S4) below this lower limit, this may be due to damage to the lighting, the solar panel, or the power cables, and a warning display or signal is issued in anticipation of human intrusion (S5). The administrator or security company (8) monitoring the data will immediately become aware of the human intrusion (S5), and the security company will rush to the location where the power generation device is installed. In addition, a red light (10) at the power generation device installation site will be turned on and an alarm device (11) will be activated. [Explanation of symbols]
