Description

Technical Field

[0001] The invention belongs to the technical field of photovoltaic power generation, and specifically relates to a data collector and a data collection method based on distributed power sources. Background Art

[0002] With the rapid development of my country's photovoltaic industry, distributed photovoltaic power generation has become an important part of the new energy field. However, due to the small scale and scattered distribution of distributed photovoltaic power generation systems, the impact of their grid-connected operation on the power grid has gradually become prominent, especially when the grid regulation capacity is insufficient, which is easy to cause grid operation risks.

[0003] At present, most of my country's distributed photovoltaic power generation systems do not have the ability to regulate and control, which is mainly reflected in the following aspects:

[0004] Insufficient data collection capabilities: Distributed photovoltaic power generation systems lack effective data collection methods and are unable to obtain system operation data in real time, making it difficult to conduct scientific and reasonable regulation.

[0005] Single control method: Most distributed photovoltaic power generation systems adopt a fixed output power control method, which cannot be dynamically adjusted according to grid demand and is difficult to achieve coordinated operation with the grid.

[0006] Poor information exchange: The information exchange between the distributed photovoltaic power generation system and the power grid is not smooth, making it difficult to achieve real-time monitoring and remote control, which is not conducive to the safe and stable operation of the power grid.

[0007] Limited control capabilities: Due to the lack of effective control methods, distributed photovoltaic power generation systems are prone to grid overload, voltage fluctuations and other problems during grid-connected operation, affecting the safe and stable operation of the grid.

[0008] In order to solve the above problems and improve the regulation and control capabilities of distributed photovoltaic power generation systems, a data collector and collection method based on distributed power sources are proposed. By improving the regulation and control capabilities of low-voltage distributed photovoltaics, it can meet the regulation needs of the power grid, realize effective regulation and management of photovoltaic power resources, and improve the power grid's ability to ensure supply and consumption, greatly alleviate the pressure on the safe operation of the power grid, and improve the economy of the power grid. Summary of the invention

[0009] The present invention aims to solve the technical problem that the current low-voltage industrial and commercial distributed photovoltaics in the above-mentioned prior art do not have the regulation capability and there are risks in the operation of the power grid.

[0010] To achieve the above purpose, the invention provides the following technical solutions:

[0011] A data collector based on distributed power supply, comprising:

[0012] The main housing has a circuit board of model N32H482 inside, and the top surface of the main housing has a female aviation plug and a nut electrically connected to the circuit board and connected to the data acquisition adapter or the inverter aviation plug for data exchange; the circuit board integrates a single-chip microcomputer, a power supply circuit, a serial communication circuit, and a clock circuit; the power supply circuit is electrically connected to the single-chip microcomputer, the wireless communication module, the serial communication circuit, and the clock circuit;

[0015] The remote communication module is inserted into the main shell by plugging and unplugging and is located on the inner side of the sliding cover for cooperating with the circuit board for data interaction and transmission. The remote communication module is provided with a pin header interface that is plugged into the female header interface on the circuit board inside the main shell. The female header interface and the pin header interface are electrically plugged together to complete data communication.

[0016] The main housing provides protection and physical protection for the circuit boards and components inside the main housing. The female aviation plug and nut enable the device to be easily connected to the data acquisition adapter or inverter for data exchange, which improves the compatibility of the device and the reliability of the connection.

[0017] The slide cover is installed on the main housing by means of a slide slot. This design facilitates maintenance and repair. The SIM card slot allows the replacement of different SIM cards, increasing the flexibility of communication and being suitable for different network environments and operators. The 4G / 5G communication unit supports the latest communication technology to ensure high-speed and efficient data transmission. The antenna screw port can enhance the signal strength and improve the stability and reliability of communication by connecting an external 4G antenna.

[0018] The remote communication module is connected to the main housing in a plug-in manner, making the installation and maintenance of the remote communication module more convenient and quick.

[0019] Preferably, the antenna screw is inserted into a bayonet slot on the housing. The bayonet slot design can provide a fixed position for the antenna screw to prevent the antenna from shaking or falling off during use.

[0020] Preferably, the main housing surface is provided with an operating status indicator light, an uplink status indicator light, a downlink status indicator light, and a maintenance status indicator light. The status indicator light can provide the user with intuitive equipment operating status information, so that the user can quickly understand the working status of the equipment.

[0022] A data acquisition method based on a distributed power supply data collector comprises the following steps:

[0023] S1. Power-on initialization: After the data logger is powered on, the microcontroller is initialized, synchronized with the clock circuit, and establishes a data exchange connection with external devices through the serial communication circuit.

[0024] S2. Full-sending status monitoring: When the data logger is powered on, it enters the full-sending status by default to collect and transmit data.

[0025] S3. Receiving control instructions: The data collector receives control instructions from the test platform through the remote communication module. The control instructions include time control and time period control.

[0026] S4. Execute control instructions:

[0027] If a time control instruction is received, the data collector executes the control at the specified time.

[0028] If a time period control instruction is received, the data collector performs control within the specified time period.

[0029] Preferably, when executing the control instruction, the overlap and coverage of the control instruction are processed as follows:

[0030] If a time period control instruction is issued during the moment control period, the data collector starts to execute the time period control after the moment control ends.

[0031] If the second period control instruction is issued when the first period control is being executed and the two periods overlap, the first period control will be canceled and the full-sending state will be restored, and the second period control will be executed when the second period arrives.

[0032] Preferably, when executing the control instruction, the content of processing the cancellation and adjustment of the control instruction is as follows:

[0033] If the second period control instruction is issued when the first period control is not executed and there is an overlap time, the data collector cancels the first period control and maintains the full sending state, and executes the second period control when the second period arrives.

[0034] If the control times of the two time periods do not overlap, the data collector will execute the two control periods normally respectively.

[0035] As a preference, ensure that the next day's control plan is not affected by the previous day, is started on time and returns to full capacity after completion.

[0036] Preferably, if the time period control execution is interrupted (such as power failure), the data collector first enters the full-fire state after power is restored, and then continues to execute the control strategy before the power failure, and resumes the full-fire state after completion.

[0037] During the entire process, the status indicator lights on the surface of the main shell display the operating status, up status, down status and maintenance status in real time, ensuring the transparency and traceability of the data.

[0038] Compared with the prior art, the technical effects and advantages of the invention are:

[0039] The data collector and collection method based on distributed power supply, after the data collector is powered on, the single-chip microcomputer is initialized, synchronized with the clock circuit, and establishes a data exchange connection with the external device through the serial communication circuit. In the full-power state, the data collector automatically collects and transmits data. The data collector receives control instructions from the test platform through the remote communication module. These instructions can be moment control or time period control. The data collector adjusts the working state according to the received control instructions and performs the control of data collection and transmission. The data collector can handle the overlap and overlap between control instructions to ensure that the control is performed according to the latest instructions. The status indicator light on the surface of the main shell displays the operating status of the equipment in real time, providing intuitive monitoring.

[0040] The data collector can be dynamically regulated according to the needs of the power grid, improving the regulation capability of the distributed photovoltaic power generation system. Real-time data collection and accurate time synchronization ensure the accuracy of the data. The period regulation covers the moment regulation, and the reasonable arrangement of the regulation plan optimizes the resource allocation and avoids the waste of resources. The data collector can adjust the working state according to the instructions of the test platform, which improves the flexibility of the system. Even in unexpected situations such as power outages, the data collector can quickly recover and continue to perform tasks, ensuring the stability of the system. The real-time display of the status indicator allows users to intuitively understand the working status of the data collector, which is convenient for maintenance and management. The system can adapt to different working environments and network conditions, increasing its applicability in different scenarios. Through effective regulation, the impact of distributed photovoltaic power generation on the power grid is reduced, and the safe operation level of the power grid is improved.

[0041] In summary, the design and working principle of the data logger based on distributed power sources make the distributed photovoltaic power generation system more intelligent and efficient, while also improving the safety and economy of the power grid. BRIEF DESCRIPTION OF THE DRAWINGS

The connection between the single-chip microcomputer 15 and the remote communication module realizes the remote communication function of the device, provides the possibility for remote monitoring and maintenance, and reduces maintenance costs.

[0068] A data acquisition method based on a distributed power supply data collector comprises the following steps:

[0069] S1. Power-on initialization: After the data collector is powered on, the single-chip microcomputer 15 is initialized, synchronized with the clock circuit 18, and establishes a data exchange connection with an external device through the serial communication circuit 17.

[0070] S2. Full-sending status monitoring: When the data logger is powered on, it enters the full-sending status by default to collect and transmit data.

[0071] S3. Receiving control instructions: The data collector receives control instructions from the test platform through the remote communication module 11. The control instructions include time control and time period control.

[0072] S4. Execute control instructions:

[0073] If a time control instruction is received, the data collector executes the control at the specified time.

[0074] If a time period control instruction is received, the data collector performs control within the specified time period.

[0075] Handling the overlap and overwriting of control instructions:

[0076] If a time period control instruction is issued during the moment control period, the data collector starts to execute the time period control after the moment control ends.

[0077] If the second period control instruction is issued when the first period control is being executed and the two periods overlap, the first period control will be canceled and the full-sending state will be restored, and the second period control will be executed when the second period arrives.

[0078] Processing cancellation and adjustment of control instructions:

[0079] If the second period control instruction is issued when the first period control is not executed and there is an overlap time, the data collector cancels the first period control and maintains the full sending state, and executes the second period control when the second period arrives.

[0080] If the control times of the two time periods do not overlap, the data collector will execute the two control periods normally respectively.

[0081] Ensure that the next day's control plan is not affected by the previous day, and is executed on time and restored to full status after completion.

[0082] If the time period control execution is interrupted (such as power outage), the data logger will first enter the full-fire state after power is restored, and then continue to execute the control strategy before the power outage, and then resume the full-fire state after completion.

[0083] During the entire process, the status indicator lights on the surface of the main housing 2 display the operating status, uplink status, downlink status and maintenance status in real time, ensuring the transparency and traceability of the data.

[0084] These steps reflect the ability of the data collector to adjust data collection and transmission behavior according to external instructions in the distributed power system, ensuring the flexibility and reliability of data collection. The details are as follows:

After the second time period control is successfully issued, the first time period control will be fully restored. When the second time period control is issued, the second time period control will be executed. After the second time period control is completed, it will be fully restored.

[0099] (1) The first period of time control is issued and the execution time is reached;

[0100] (2) issuing the second period of time control and making the two periods of time control overlap;

[0101] (3) The first period of time control is cancelled and full-time status is restored;

[0102] (4) When the second period of time is reached, the control plan begins to be implemented;

[0103] (5) After the second period of time is completed, the full-load state is restored;

[0104] 6. Issue time period control. When the first period control is not executed, issue the second period control and make the two period controls overlap. After the first period control is cancelled, it is still in full-send state. The second period control starts to be executed when the execution time comes. After the second period control is completed, the full-send state is restored.

[0125] The data collector can adjust the data collection and transmission mode according to the instructions issued by the test platform, allowing regulation and control according to needs in different time periods, improving the flexibility of the system. The data collector can respond to regulation and control instructions in a timely manner and adjust the working status according to the time or time period requirements, ensuring the real-time nature of data collection and transmission.

[0126] By covering the time control with the time control, and reasonably arranging the overlap and execution order of the control plan, the system can use resources more efficiently and avoid waste of resources. Even in the case of interruption of control execution (such as power failure), the data collector can be restored to full state after power-on and continue to execute the previous control strategy to ensure data continuity and system reliability. The real-time display of the status indicator allows users to intuitively understand the working status of the data collector, which is convenient for maintenance and management.

[0127] The execution of the second day's plan is not affected by the first day's plan, ensuring the independence and accuracy of plan execution. When the first period of time regulation is not executed, the system can flexibly cancel the original plan without affecting the subsequent regulation execution, enhancing the system's fault tolerance. For non-overlapping period regulation, the system can execute them normally separately, optimizing the allocation and utilization of resources.

[0128] The system can adapt to different working environments. Even in unexpected situations such as power outages, it can quickly recover and continue to perform tasks, ensuring the stability of the system.

[0129] In summary, these benefits make the data collector based on distributed power more efficient, stable, and easy to manage and maintain, thereby improving the performance and reliability of the entire distributed energy system.
