Description

Technical Field

[0001] The utility model belongs to the technical field of electrochemical energy storage battery power regulation, and in particular relates to an adaptive battery power regulation device. Background Art

[0002] Currently, when electrochemical energy storage batteries are combined with thermal power plants to participate in the secondary frequency regulation system of the power grid, their regulation performance mostly relies on the battery's own capacity. When the unit increases or decreases load, the battery becomes fully discharged or fully charged, and the auxiliary regulation function is lost, affecting the overall regulation performance of the unit, resulting in reduced regulation performance and affecting the secondary frequency regulation auxiliary service revenue. The adaptive battery capacity regulation device is an intelligent device that can enhance the endurance of the battery's inherent power, maximize the inherent capacity of the electrochemical energy storage battery, and maximize the secondary frequency regulation performance. This device is configured using a more flexible DCS system (Shanghai Emerson Process Management Co., Ltd. OVATION3.3.0). The average battery capacity is introduced into the DCS through the battery management system and the battery cooperative control system. Based on the current battery capacity, it automatically adjusts the deviation between the unit's output power and the grid's AGC command, changing the battery's passive charging and discharging state. Before the battery is about to be fully discharged or empty and loses its regulation function, the unit's regulation capacity is actively utilized to charge and discharge the battery, keeping the battery active at all times, thereby improving the responsiveness of the thermal-storage combined regulation project.

[0003] However, in actual use, this adaptive battery power regulating device needs to be fixed between the back plate and the mounting rail in order to achieve the installation and fixation of the device body. However, since the traditional bolt fixation is adopted between the back plate and the mounting rail, the device will spend more time on the disassembly and assembly of the bolts during actual installation and debugging, which is time-consuming and labor-intensive, and it is impossible to quickly adapt the installation height according to the actual installation environment. There are certain disadvantages. Therefore, the present invention needs to improve and optimize this adaptive battery power regulating device. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Example 1

[0020] See also Figure 1 and Figure 2 , is the first embodiment of the present utility model, which provides a technical solution: an adaptive battery power regulation device, comprising

[0021] An L-shaped back panel 1, two device bodies 2 mounted on the front surface of the L-shaped back panel 1, two T-shaped mounting rails 3 disposed on the rear of the L-shaped back panel 1, and a rectangular base block 4 welded and fixed to the top surface of the L-shaped back panel 1. Two sliding sleeves 11 corresponding to the T-shaped mounting rails 3 are welded and fixed to the rear surface of the L-shaped back panel 1, and the sliding sleeves 11 are slidably mounted on the surfaces of the T-shaped mounting rails 3.

[0022] The adjusting mechanism 5 is also provided between the rectangular base block 4 and the T-shaped mounting rail 3, including a movable plate 51 movably mounted on the front surface of the rectangular base block 4, two limiting rods 52 welded and fixed to the inner surface of the movable plate 51, and a plurality of limiting slots 53 provided on the surface of the T-shaped mounting rail 3. The rear end of the limiting rod 52 passes through the rectangular base block 4 and is inserted into one of the limiting slots 53, so as to achieve stable limiting of the rectangular base block 4 and the L-shaped back plate 1 during daily use. The adjusting mechanism 5 also includes an inner slide groove 54 provided inside the center of the rectangular base block 4, an inner slide plate 55 and a spring 56 installed in the inner slide groove 54, and a connecting rod 57 welded and fixed to the front surface of the inner slide plate 55. The front end of the connecting rod 57 passes through the front surface of the rectangular base block 4 and is fixed to the movable plate 51, and the inner slide plate 55 slides in the inner slide groove 54. Under the push of the spring 56, the movable plate 51 can remain aligned with the rectangular base during daily use. The rear end of the limiting card rod 52 can be inserted into the limiting card slot 53 at another position, thereby completing the re-limiting of the rectangular base block 4 and the L-shaped back plate 1, and realizing convenient adjustment of the height of the device body 2.

[0023] One end of the spring 56 abuts against the front surface of the inner slide plate 55 , the other end of the spring 56 abuts against the inner wall of the inner slide groove 54 , and the connecting rod 57 passes through the inner side of the spring 56 .

[0024] Among them, two through-holes are opened on the surface of the rectangular base block 4 for the limit rod 52 to pass through, and a middle hole communicating with the inner slide groove 54 is opened at the center of the front surface of the rectangular base block 4, and the middle hole corresponds to the connecting rod 57, allowing the connecting rod 57 to pass through smoothly.

[0025] The top surface of the device body 2 is connected to a plurality of signal lines 21 .

[0026] The device body 2 is provided with a battery cooperative control module and a battery power adaptive module. During actual operation, the device body 2 in this device is first installed in a cabinet and then connected between the electrochemical energy storage battery and the thermal power unit via a signal line 21. The device body 2 is configured internally using a DCS system (OVATION3.3.0 of Shanghai Emerson Process Management Co., Ltd.). The average battery power is then introduced into the DCS via the battery management system and the battery cooperative control module. Referring to the current battery power, the battery power adaptive module automatically adjusts the deviation between the output power of the thermal power unit and the grid AGC command, thereby changing the passive charging and discharging state of the battery. Specifically, when the electrochemical energy storage battery power is greater than 70%, the unit output power command = AGC command * 98.5%, achieving automatic battery discharge. When the electrochemical energy storage battery power is less than 30%, the unit output power command = AGC command * 101.5%, achieving automatic battery charging. Therefore, before the battery is about to be fully charged or discharged and loses its regulating function, the unit's regulating capacity is actively utilized to charge and discharge the battery, keeping the battery active at all times, thereby improving the responsiveness of the thermal-storage joint regulation project.

[0027] Example 2

[0028] See also Figures 1 to 3 , which is the second embodiment of the present utility model. This embodiment is based on the previous embodiment, but the difference is that the multiple signal lines 21 at the top of the device can be isolated and limited by the provided line limiting mechanism 6 to avoid the lines from getting tangled with each other, thereby achieving the purpose of overall limiting the lines.

[0029] Specifically, a limiting mechanism 6 is provided at the front end of the L-shaped back panel 1 relative to the top of the device body 2. The limiting mechanism 6 includes a rectangular base strip 61 welded and fixed to the front end surface of the L-shaped back panel 1, and the rectangular base strip 61 is at the top of the device body 2. The front surface of the rectangular base strip 61 is provided with a plurality of strip bayonet holes 62 for the signal lines 21 to be inserted into, which can organize and limit the multiple signal lines 21 at the top of the device body 2. The inner walls on both sides of the strip bayonet hole 62 are glued and fixed with hemispherical elastic protrusions 63. The hemispherical elastic protrusion 63 is made of rubber material and will undergo elastic deformation when squeezed. The hemispherical elastic protrusion 63 fits the signal line 21, so that the signal line 21 can be limited by the two hemispherical elastic protrusions 63 after being inserted into the strip bayonet hole 62.
