Description

Technical Field

[0001] This invention relates to the field of photovoltaic loss control technology, specifically to a smart loss control system and method for photovoltaic power plants. Background Technology

[0002] A photovoltaic (PV) power plant refers to a PV power generation system connected to the power grid and transmitting electricity to it. PV power plant losses are divided into two types: uncontrollable losses and controllable losses. As the names suggest, uncontrollable losses are those that cannot be reduced or controlled by humans. This is limited by technological advancements and the construction budget of PV power plants, and cannot be reduced manually. Examples include transmission line losses and inverter efficiency losses. Controllable losses are those that can be reduced or controlled by humans, such as heat generation losses, shading losses, and tilt offset losses. Currently, PV power plant loss control primarily targets controllable losses that are easily reduced or controlled manually. These are often carried out alongside regular maintenance, involving spraying or manual operations for cooling, dust removal, foreign object removal, and tilt correction. While current loss control operations can achieve some effect, they are merely simple, mechanical processes. After the operation, it's impossible to determine whether loss control has been completed, and traditional loss control operations are also less timely and thorough. Summary of the Invention

[0003] In view of the problems existing in the prior art, the purpose of this invention is to provide a smart loss control system and method for photovoltaic power plants. This smart loss control system and method for photovoltaic power plants can accurately determine whether loss control has been completed, and has good timeliness and thoroughness.

[0004] The above-mentioned technical objective of this invention is achieved through the following technical solution: a smart loss control system for photovoltaic power plants, comprising:

[0005] The monitoring system includes a flow rate monitoring system for monitoring the fluid flow rate on the light-receiving side of the photovoltaic panel, a temperature monitoring system for monitoring the surface and surrounding temperature of the photovoltaic panel, and a power generation monitoring system for monitoring the power generation of the photovoltaic panel.

[0006] The loss control system includes a spray system and a trickle system for providing water with initial velocity and water without initial velocity to the light-receiving side of the photovoltaic panel, respectively. The water outlet of the trickle system is located at the highest point of the photovoltaic panel. The trickle system can generate a water film that fully covers the light-receiving side of the photovoltaic panel. The spray range of the spray system can fully cover the light-receiving side of the photovoltaic panel.

[0007] The control center is connected to both the monitoring system and the loss control system. It is used to receive, calculate, summarize, store, or retrieve data collected from the monitoring system, and to send control commands to the monitoring system or the loss control system.

[0008] In some embodiments, the loss control system further includes a blower system for blowing air onto the surface and surrounding area of ​​the photovoltaic panel.

[0009] In some embodiments, the control center can connect to the network to obtain solar irradiance data of the location of the photovoltaic power station.

[0010] A smart loss control method for photovoltaic power plants includes the following steps:

[0011] S1 divides the photovoltaic panels of the photovoltaic power station into grid-like areas;

[0012] S2 sets up loss control and monitoring systems in each grid area and establishes a control center connected to each loss control and monitoring system;

[0013] After the photovoltaic panels have been installed, debugged, or maintained, S3 uses a trickle system and flow rate monitoring system to obtain the flow rate of trickle water on the surface of the photovoltaic panels. The obtained data is then input to the control center to obtain the flow rate of trickle water on the surface of the photovoltaic panels under the condition of no uncontrollable loss.

[0014] S4 uses a power generation monitoring system and a temperature monitoring system to record the real-time power generation and temperature of the photovoltaic panels, and then inputs the acquired data into the control center to generate change curves and build models based on the acquired power generation and temperature data.

[0015] S5, combined with the monitoring system, based on the model in step S4, determines whether there are any abnormalities in the current power generation and / or temperature of the photovoltaic panel;

[0016] If the power generation and / or temperature of the photovoltaic panel are not abnormal, it means that there is no controllable loss of the photovoltaic panel. At this time, there is no need to control the loss and the operation can be stopped.

[0017] When the power generation and / or temperature of the photovoltaic panel are abnormal, it indicates that there is controllable loss in the photovoltaic panel. At this time, continue to the next step S6.

[0018] S6 uses the control center to retrieve the loss control system to sequentially perform spray cooling and rinsing and trickle test on the photovoltaic panel. During the trickle test, the flow rate monitoring system is used to obtain the flow rate of the trickle water on the surface of the photovoltaic panel and to determine whether the flow rate of the trickle water corresponds to the flow rate in step S3.

[0019] When the measured flow rate of the trickle water corresponds to the flow rate in step S3, it indicates that loss control has been completed and the operation ends.

[0020] If the measured flow rate of the trickle water does not correspond to the flow rate in step S3, it indicates that loss control has not been completed and further on-site inspection is required.

[0021] In some embodiments, the specific steps of region division in step S1 are as follows:

[0022] Obtain a floor plan of the photovoltaic power station;

[0023] On the plan, draw an outer rectangle for the photovoltaic panel clusters within the photovoltaic power station;

[0024] Draw a grid at equal intervals within the rectangle, and number the photovoltaic panels within each grid.

[0025] Step S2 also includes assigning the same number to the loss control system and monitoring system in different grids.

[0026] In some embodiments, in step S3, after the photovoltaic panel has just been installed, debugged or maintained, the flow rate of the trickle water on the surface of the photovoltaic panel is obtained multiple times using a trickle system and a flow rate monitoring system, and the obtained data is input to the control center to obtain the flow rate range of the trickle water on the surface of the photovoltaic panel under the condition of no uncontrollable loss.

[0027] In step S6, during the trickle test, the flow rate of the trickle water on the surface of the photovoltaic panel is obtained through a flow rate monitoring system, and it is determined whether the flow rate of the trickle water is within the flow rate range in S3.

[0028] In some embodiments, in step S4, the time period for generating the change curves of power generation and temperature data is at least one maintenance cycle.

[0029] In some embodiments, in step S6, after completing further maintenance on-site, a trickle test is performed again using a trickle system and a flow rate monitoring system to determine whether the flow rate of the trickle water corresponds to the flow rate in step S3. The trickle test and on-site maintenance are repeated multiple times until the flow rate of the trickle water corresponds to the flow rate in step S3, so as to complete the loss control.

[0030] In summary, the present invention has the following beneficial effects:

[0031] This intelligent loss control system and method for photovoltaic power plants forms a water film on the sun-receiving side of the photovoltaic panels by setting up a trickle system and a flow velocity monitoring system, and monitors the flow velocity of the water film. When there is dust accumulation, foreign objects, or tilt deviation on the sun-receiving side of the photovoltaic panels, it will affect the flow velocity of the water film. Therefore, the presence of dust accumulation, foreign objects, or tilt deviation on the sun-receiving side of the photovoltaic panels can be determined by observing the changes in the flow velocity of the trickle water film. This invention is applicable immediately after the photovoltaic panels have undergone installation, commissioning, or maintenance, using the trickle system and flow velocity monitoring system to obtain the current surface velocity of the photovoltaic panels. The flow rate of trickle water on the photovoltaic panel surface is measured and the acquired data is input to the control center to obtain the flow rate of trickle water on the photovoltaic panel surface under the condition of no controllable loss. This flow rate is the benchmark flow rate for judging whether there is dust accumulation, foreign objects or tilt deviation on the sun-receiving side of the photovoltaic panel. Therefore, after the loss control operation is completed, the trickle test can be used to determine whether the problem causing controllable loss of the photovoltaic panel has been solved, thereby accurately judging whether loss control has been completed. A trickle test is performed after each loss control operation to achieve a more thorough loss control of the photovoltaic power station.

[0032] This invention uses a power generation monitoring system and a temperature monitoring system to record the real-time power generation and temperature of photovoltaic panels. The acquired data is then input into a control center, where a change curve is generated based on the acquired power generation and temperature data, and a model is constructed. The model is then combined with the monitoring system to determine whether there are any abnormalities in the current power generation and / or temperature of the photovoltaic panels. The monitoring system operates in real time and can report any abnormalities in a timely manner, enabling timely loss control.

[0033] When controllable losses are detected in a photovoltaic panel, this invention uses a loss control system accessed at the control center to sequentially perform spray cooling and rinsing, as well as trickle testing. The spraying operation addresses controllable losses caused by heat buildup and dust accumulation. It also eliminates the influence of easily washable obstructions on the trickle test, ensuring its accuracy. The result of the trickle test determines whether on-site inspection is necessary. Specifically, after spraying, the invention uses a trickle test to determine if loss control is complete. If the test result indicates successful loss control, the spraying process has resolved the controllable losses. If the test result indicates unsuccessful loss control, spraying alone is insufficient, necessitating on-site inspection and repair. Therefore, trickle testing effectively saves manpower, eliminating the need for unnecessarily on-site visits. Attached Figure Description

[0035] Figure 2 This is a schematic diagram of the usage method of the present invention. Detailed Implementation

[0036] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0037] In the description of this invention, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this invention.

[0038] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0039] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0040] like Figure 1 As shown, a smart loss control system for photovoltaic power plants includes a monitoring system, a loss control system, and a control center.

[0041] The monitoring system includes a flow rate monitoring system for monitoring the fluid velocity on the light-receiving side of the photovoltaic panel, a temperature monitoring system for monitoring the surface and surrounding temperature of the photovoltaic panel, and a power generation monitoring system for monitoring the power generation of the photovoltaic panel. The flow rate monitoring system, temperature monitoring system, and power generation monitoring system can all be equipped with monitoring devices that can transmit data via the network.

[0042] The loss control system includes a spray system and a trickle system, which respectively provide water with initial velocity and no initial velocity to the light-receiving side of the photovoltaic panel. The outlet of the trickle system is located at the highest point of the photovoltaic panel, and it can generate a water film that completely covers the light-receiving side of the photovoltaic panel. The spray system can also fully cover the light-receiving side of the photovoltaic panel. The water sprayed by the spray system can cool the photovoltaic panel and wash away obstructions on the light-receiving side of the photovoltaic panel, thereby solving the loss caused by high temperature and obstruction to the photovoltaic panel, and playing a dual role in loss control. Before spraying, the water film formed by the trickle system on the light-receiving side of the photovoltaic panel can soften and soak away stubborn obstructions (such as bird droppings) to improve the subsequent spraying effect. The trickle system can also be used to judge the photovoltaic panel. The purpose of tilt angle deviation is to monitor the flow rate of the trickle water after the water film is formed on the sun-receiving side of the photovoltaic panel. The larger the tilt angle of the photovoltaic panel, the greater the flow rate of the trickle water, and the smaller the tilt angle, the smaller the flow rate of the trickle water. A standard flow rate (i.e., the flow rate of the trickle water after the photovoltaic panel is properly installed and the surface is clean) can be stored in advance. When monitoring the trickle water flow rate later, the measured flow rate can be compared with the standard flow rate to determine whether the tilt angle of the photovoltaic panel has deviated, so as to accurately find the cause of photovoltaic panel loss. The loss control system can also include a blower system for blowing air onto the surface and surrounding area of ​​the photovoltaic panel. The blower system can accelerate the heat dissipation of the photovoltaic panel and blow away obstructions (such as dust, leaves, etc.) on the surface of the photovoltaic panel.

[0043] The control center is connected to both the monitoring system and the loss control system. It is used to receive, calculate, summarize, store, or retrieve data collected from the monitoring system, and to send control commands to the monitoring system or the loss control system. The control center can also connect to the network to obtain solar irradiance data of the location of the photovoltaic power station.

[0044] This system monitors photovoltaic (PV) panels in real time using temperature and power generation monitoring systems. It can also estimate the temperature and power generation of the PV panels by combining data on solar irradiance at the PV site location and the PV panel model and specifications. By comparing real-time monitoring values ​​with estimated values, the system assesses the PV panel's loss status. When controllable losses occur, the control center sends instructions to the loss control system, which uses a spray system, trickle system, and blower system to cool and clean the PV panels, achieving initial loss control. After initial loss control, a trickle test is conducted using the trickle system and flow rate monitoring system. Specifically, after the trickle system forms a water film on the sun-receiving side of the PV panel, the flow rate monitoring system measures the trickle flow. The system monitors the flow rate of the trickle water. The larger the tilt angle of the photovoltaic panel, the greater the trickle water flow rate, and vice versa. A standard flow rate (the flow rate of the trickle water when the photovoltaic panel is properly installed and its surface is clean) is pre-stored. During subsequent monitoring of the trickle water flow rate, the measured flow rate is compared with the standard flow rate to determine if the photovoltaic panel tilt angle has deviated or if there are stubborn obstructions that cannot be removed by spraying. This helps determine whether further on-site loss control is necessary. This system can accurately identify the causes of photovoltaic panel damage, enabling accurate, thorough, effective, and timely loss control. Furthermore, the cause of photovoltaic panel damage does not require manual judgment; it can be determined through trickle testing, achieving intelligent loss control.

[0045] A smart loss control method for photovoltaic power plants includes the following steps:

[0046] S1 divides the photovoltaic panels of the photovoltaic power station into grid-like areas, which can be done using the following methods:

[0047] A plan view of a photovoltaic power station can be obtained using drones or satellite maps;

[0048] On the plan, draw an outer rectangle for the photovoltaic panel clusters within the photovoltaic power station;

[0049] Draw a grid at equal intervals within the rectangle and number the photovoltaic panels in each grid. Different numbers can be assigned to different personnel for daily loss control management. Such detailed management can achieve rapid response and timely loss control.

[0050] S2 sets up a loss control system and a monitoring system in each grid area, and establishes a control center connected to each loss control system and monitoring system. The loss control system and monitoring system in different grids can be assigned the same number as in step S1, so as to facilitate corresponding management.

[0051] S3: After the photovoltaic panel has just been installed, debugged, or maintained, the flow rate of the trickle water on the surface of the photovoltaic panel is obtained using a trickle system and a flow rate monitoring system. The obtained data is then input to the control center to obtain the flow rate of the trickle water on the surface of the photovoltaic panel under the condition of no controllable loss. Considering factors such as measurement error, the above steps can be performed multiple times after the photovoltaic panel has just been installed, debugged, or maintained, using a trickle system and a flow rate monitoring system. The obtained data is then input to the control center to obtain the range of the flow rate of the trickle water on the surface of the photovoltaic panel under the condition of no controllable loss.

[0052] S4 uses a power generation monitoring system and a temperature monitoring system to record the real-time power generation and temperature of the photovoltaic panels. The acquired data is then input into the control center, which generates a change curve based on the acquired power generation and temperature data and builds a model. When building the model, the solar radiation intensity data of the photovoltaic site can be combined to build an accurate, objective model that conforms to local meteorological conditions. In addition, the time period for generating the change curve of power generation and temperature data is at least one maintenance cycle. Such a data change curve can eliminate randomness to the greatest extent and has universality, objectivity and reference value.

[0053] S5, combined with the monitoring system, based on the model in step S4, determines whether there are any abnormalities in the current power generation and / or temperature of the photovoltaic panel;

[0054] If the power generation and / or temperature of the photovoltaic panel are not abnormal, it means that there is no controllable loss of the photovoltaic panel. At this time, there is no need to control the loss and the operation can be stopped.

[0055] When the power generation and / or temperature of the photovoltaic panel are abnormal, it indicates that there is controllable loss in the photovoltaic panel. At this time, continue to the next step S6.

[0056] S6 uses the control center to retrieve the loss control system to sequentially perform spray cooling and rinsing and trickle test on the photovoltaic panel. The trickle test involves forming a water film on the light-receiving side of the photovoltaic panel through the trickle system, and then monitoring the flow rate of the trickle water through the flow rate monitoring system. The measured flow rate data is then transmitted to the control center for comparison and processing. During the trickle test, the flow rate monitoring system obtains the flow rate of the trickle water on the surface of the photovoltaic panel at this time and determines whether the flow rate of the trickle water is within the flow rate range in step S3.

[0057] When the measured flow rate of the trickle is within the flow rate range in step S3, it indicates that loss control has been completed and the operation ends.

[0058] When the measured flow rate of the trickle water is outside the flow rate range in step S3, it indicates that the tilt angle of the photovoltaic panel has shifted, there are stubborn foreign objects on the photovoltaic panel, or the photovoltaic panel is damaged. At this time, the damage control has not been completed and further on-site inspection is required.

[0059] In the above steps, after completing further on-site maintenance, a trickle test is conducted again using a trickle system and a flow rate monitoring system to determine whether the flow rate of the trickle water corresponds to the flow rate in step S3. The trickle test and on-site maintenance are repeated multiple times until the flow rate of the trickle water corresponds to the flow rate in step S3, in order to complete loss control.

[0060] This intelligent loss control system and method for photovoltaic power plants forms a water film on the sun-receiving side of the photovoltaic panels by setting up a trickle system and a flow velocity monitoring system, and monitors the flow velocity of the water film. When there is dust accumulation, foreign objects, or tilt deviation on the sun-receiving side of the photovoltaic panels, it will affect the flow velocity of the water film. Therefore, the presence of dust accumulation, foreign objects, or tilt deviation on the sun-receiving side of the photovoltaic panels can be determined by observing the changes in the flow velocity of the trickle water film. This invention is applicable immediately after the photovoltaic panels have undergone installation, commissioning, or maintenance, using the trickle system and flow velocity monitoring system to obtain the current surface velocity of the photovoltaic panels. The flow rate of trickle water on the photovoltaic panel surface is measured and the acquired data is input to the control center to obtain the flow rate of trickle water on the photovoltaic panel surface under the condition of no controllable loss. This flow rate is the benchmark flow rate for judging whether there is dust accumulation, foreign objects or tilt deviation on the sun-receiving side of the photovoltaic panel. Therefore, after the loss control operation is completed, the trickle test can be used to determine whether the problem causing controllable loss of the photovoltaic panel has been solved, thereby accurately judging whether loss control has been completed. A trickle test is performed after each loss control operation to achieve a more thorough loss control of the photovoltaic power station.

[0061] This invention uses a power generation monitoring system and a temperature monitoring system to record the real-time power generation and temperature of photovoltaic panels. The acquired data is then input into a control center, where a change curve is generated based on the acquired power generation and temperature data, and a model is constructed. The model is then combined with the monitoring system to determine whether there are any abnormalities in the current power generation and / or temperature of the photovoltaic panels. The monitoring system operates in real time and can report any abnormalities in a timely manner, enabling timely loss control.

[0062] When controllable losses are detected in a photovoltaic panel, this invention uses a loss control system accessed at the control center to sequentially perform spray cooling and rinsing, as well as trickle testing. The spraying operation addresses controllable losses caused by heat buildup and dust accumulation. It also eliminates the influence of easily washable obstructions on the trickle test, ensuring its accuracy. The result of the trickle test determines whether on-site inspection is necessary. Specifically, after spraying, the invention uses a trickle test to determine if loss control is complete. If the test result indicates successful loss control, the spraying process has resolved the controllable losses. If the test result indicates unsuccessful loss control, spraying alone is insufficient, necessitating on-site inspection and repair. Therefore, trickle testing effectively saves manpower, eliminating the need for unnecessarily on-site visits.

[0063] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
