Description

Technical Field

[0001] The present invention relates to the technical field of power equipment, and more specifically, to a teaching chassis with new energy power generation function. Background Art

[0002] The construction of a new power system has an increasing demand for high-quality technical and skilled talents. However, in actual teaching, due to the shortage of experimental equipment and the limitation of teaching methods, the cultivation of professional talents in the field of new energy power generation technology still faces many challenges.

[0003] As a core course for the power supply and utilization technology major and the new energy power generation technology major, the course "New Energy Power Generation and Control Technology" mainly teaches the power generation technology of emerging energy sources such as solar energy and wind energy and their grid connection control strategies. This is a typical application-oriented course. However, in actual teaching, the following main problems have emerged: (1) Teaching is mainly theory-based, with insufficient practical links The application characteristics of this course determine the importance of practical teaching. However, the current teaching method still mainly focuses on theoretical explanations, and the content is too abstract, resulting in low learning interest among students and difficulty in stimulating their enthusiasm for independent learning. Students often cannot truly experience the important role of new energy power generation technology in actual production and life, and the learning goals become mere formalities. In most cases, they only "memorize by rote" to obtain credits or pass exams.

[0004] (2) Lack of cultivation of practical innovation ability The core of an application-based course lies in the actual application of knowledge. However, the lack of practical links in current teaching is relatively serious. Due to the insufficient engineering application experience of some teachers, the course content mainly remains at the theoretical level and fails to provide students with a platform or conditions for practical innovation. This not only weakens the practicality of the course but also easily makes students have doubts about the importance and practical value of the course, further reducing their learning initiative.

[0005] (3) The number of competition equipment is limited and not suitable for daily teaching In energy and power related majors, the equipment of the skills competition - "New Power System Technology and Application" related to power supply and utilization technology and new energy power generation technology has obvious deficiencies when applied to teaching. For example, the equipment is large in volume (each unit occupies about 20 square meters) and heavy in weight (over 1 ton), and at the same time, each piece of equipment can only be operated by at most 3 students. This makes it difficult for vocational colleges to equip enough equipment in the short term, resulting in difficulties in popularizing and applying these equipment in daily teaching.

[0006] In response to the above three problems, the research and development of this device focuses on solving the pain points such as insufficient practice and weak cultivation of innovation ability in teaching. It focuses on two new energy power generation technologies, solar power generation technology and wind power generation technology, which are the most widely used and easier to miniaturize. By integrating the wind-light-storage integrated energy system into the device and comprehensively simulating the operating principle of the new energy power generation system, it not only meets the practical teaching needs of the course, but also provides a comprehensive platform for students integrating theoretical learning, practical operation and innovative development, effectively improving the practicality of teaching and the cultivation effect.

[0024] Reference Figure 3 Describe Embodiment 2. This embodiment further describes Embodiment 1, and the technical features and design methods are as follows: (1) Function integration and core features Compact design and modular layout: The volume of the device is only 100×50×22 cm, and the weight is 15 kg, which is more miniaturized than traditional devices; this design reduces the occupied space and improves the portability and popularization in the teaching scenario; Integrate multiple power generation technologies: Through the comprehensive integration of photovoltaic power generation systems, wind power generation systems, and energy storage battery systems, comprehensively simulate the new energy power generation process, and meet the integrity requirements of teaching for the entire process of new energy power generation and grid connection control technology; (2) Technical features of the control layer Implement core control based on PLC20: Each key device is centrally managed and coordinated through a programmable logic controller (PLC20) to achieve flexible control of the power generation module, energy storage module, and load.

Combined synergy: The wind power generation module and the photovoltaic module realize dynamic and automatic input and cut-out through the control system, reflecting the characteristics of wind-solar complementary technology; 3. Intelligent interconnection characteristics: The equipment reserves communication interfaces, supports the expansion of teaching content of "energy Internet" and "industrial Internet", can upload operation data through the network or interconnect with other devices, and supports real-time monitoring and remote optimization; 4. Modular and easy to expand: The device ports are designed for plug-and-play, which is convenient for users to expand function modules or connect other devices, taking into account the diverse needs of teaching and competitions; In this embodiment, the relationship and logic between technical features can be sorted out by the following logical process to show the relationship between internal technical features of the system: The first step: Compact design of equipment miniaturization → Achieve portable and multi-scenario teaching. The compact and modular layout greatly reduces the volume and weight of the equipment. Compared with traditional competition equipment, the volume is reduced to 1 / 8 and the weight is reduced to 1 / 100. At the same time, scientific module division ensures the integrity of teaching functions, enhances portability and flexibility, and is especially suitable for multi-scenario requirements such as actual teaching and skills competitions.

[0025] Step 2: Functional Integration of Energy System → Achieving Teaching Practicality and Integrity The photovoltaic power generation system, wind power generation system, energy storage battery system, and control system are integrated into one. Through modular design, it covers more than 80% of the knowledge points in the course of "New Energy Generation and Control Technology", and directly cuts into the grid-connected power generation principle and core control technology. This structure is suitable for knowledge consolidation and practical teaching.

[0026] Step 3: Centralized Control Based on PLC20 → Achieving Flexibility and Expandability The PLC20 controller realizes the dynamic control of photovoltaic, wind power, energy storage, and load through programming, and integrates components such as relay 19 and power supply module at the same time. Its system stability, control flexibility, and expandability are far superior to traditional fixed mechanical designs. Through the optimization of the PLC20 algorithm, different operating scenarios of the power generation system can also be simulated.

[0027] Step 4: Embedding MPPT and Remote Adjustment Technology → Reflecting Intelligence The MPPT technology allows photovoltaic modules to obtain the maximum light energy utilization rate by automatically adjusting the angle, and realizes the configuration update and monitoring of operating parameters through the remote network, meeting the requirements of modern teaching for intelligent operation.

[0028] Through innovative teaching methods and the integration model of competition and teaching, this invention realizes "promoting teaching and reform through competitions", combines "classroom teaching" with "skill competitions", provides an ideal solution for vocational colleges to use in skill competitions and curriculum teaching, enriches teaching means, and is compatible with modern energy and industrial Internet technologies: The equipment reserves interfaces and communication functions to realize the teaching application of the content of the energy Internet and the industrial Internet, conforms to the latest technological development trend of the industry, and provides guarantee for students' actual employment skills.

[0029] In specific applications, there is an energy storage power supply 22, a motor 21, a PLC 20, and several relays 19 in the space of the control box 2 composed of acrylic plates on the operation table 1 of the teaching chassis set by the present invention, which constitute our control part. There are also several buttons on the acrylic plate. There is a fan, a simulated wind turbine 21, a wind-solar hybrid controller 13, a photometric sensor processor 11, a communication module 15, and a solar panel 10 on another fixed plate 16. First, the energy storage power supply 22 supplies power to each device. In the manual mode, we give a signal to the input end of the PLC 20 by pressing the eastward button, and then through the internal program. The PLC 20 will give a signal to the output end, so that the relay 19 is attracted. Correspondingly, the solar panel 10 moves eastward, and the motor 21 also rotates while moving eastward. The same principle applies to moving westward. There are limits in the northward and southward movements. When the solar panel 10 moves northward or southward to the limit, the solar panel 10 will stop, but the motor 21 still rotates. When we press the battery panel input button, the solar panel input button and the solar panel input display button light up simultaneously. At the same time, when light shines on the solar panel, the solar panel is put into operation and emits electricity, and the electricity generated is passed through the wind-solar hybrid controller 13. It is transmitted to the energy storage battery. In the manual mode, we press the east-west button to make the swing rod on the acrylic plate move from east to west until it stops at the limit. The same principle applies to moving west to east. We press the start button of the wind power generation fan 14. The start button of the fan will give an input signal to the PLC 20. The PLC 20 outputs a signal through the internal program to make the relay 19 attracted. Then the wind power generation fan 14 rotates to drive the simulated wind turbine 21 to rotate. The electricity generated by the simulated wind turbine 21 will be transmitted to the wind-solar hybrid controller 13. The wind-solar hybrid controller 13 then transmits it to the charging battery for storage. We switch to the automatic mode through the rotary switch. In the automatic mode, we press the start button, and the start button light comes on. At the same time, an automatic program start signal is given to the PLC 20. Through the program compilation of the PLC 20, the solar panel 10 will move eastward for 2 seconds first, then move westward for 2 seconds. It moves northward and southward for 2 seconds respectively. After the movement ends, we press the lamp input button, and the lamp input button and the lamp display button light up simultaneously. At the same time, the lamp is put into operation. We hold the irradiation lamp and irradiate the light sensor in different directions. Then the signal of the light sensor will be transmitted to the light sensor processing unit and the communication module 15. The light sensor processing unit and the communication module 15 will output a signal through the internal circuit board and transmit it to the PLC 20. For the PLC 20, the signal transmitted by the light sensor processing unit and the communication module 15 is used as the input signal, and different actions under different directions of irradiation are carried out through the internal program. When the searchlight irradiates in the north direction, the photovoltaic panel will move northward, and the same principle applies to other directions.Whether in manual mode or automatic mode, when the solar panel 10, the fan, the swing rod, the motor 21, and the relay 19 are in motion, when the stop button and the emergency stop button are pressed, the button lights will turn on, an input signal will be sent to the PLC 20, and the corresponding actions will all stop immediately.
