Description

Technical Field

[0001] The present invention belongs to the technical field of voltage regulators, and in particular relates to a refined voltage regulator for high energy-efficiency power distribution. Background Art

[0002] The voltage regulator is a device in the power system that is used to adjust the voltage in the transmission line to meet the voltage requirements of different power loads. In the power system, the voltage level of the transmission line is usually high voltage. The main function of the voltage regulator is to reduce the voltage transmitted from the high-voltage transmission line to the user end to reach a voltage level suitable for household, commercial and industrial electricity use, so as to ensure the stable operation of the power system and meet the power needs of users. The voltage regulator consists of a voltage regulating circuit, a control circuit and a servo motor. When the input voltage or load changes, the control circuit samples, compares, and amplifies, and then drives the servo motor to rotate, so that the position of the transformer carbon brush changes, and the output voltage is kept stable by automatically adjusting the coil turns ratio. Larger capacity voltage regulators also work on the principle of voltage compensation.

[0003] The voltage regulator has a sliding contact and a ring-shaped coil, which can change the position of the contact in the ring-shaped coil to output different voltages. Another method is to use electronic components or relays to change the different taps of the secondary line group to adjust the voltage. The voltage regulator generates a lot of heat during operation. The problem with the above technology is that in the prior art, the voltage regulator generates a high amount of heat during operation. Generally, heat dissipation is performed by using a heat dissipation port, but the heat dissipation effect is not obvious, which easily leads to failure of internal components. At the same time, further analysis shows that the voltage regulator of the prior art has a simple structure and function, and cannot achieve refined voltage regulation for the voltage connected to the load. Traditional voltage regulators have high energy consumption, especially in the case of large voltage fluctuations, the energy loss is more serious. In the power system, due to the influence of various factors (such as load changes, power grid failures, transmission line impedance, etc.), the grid voltage often fluctuates. This voltage fluctuation is irregular. If refined voltage regulation control cannot be achieved, it may cause impact or even damage to electrical equipment, affecting the normal operation and life of the equipment.

The hot air flow generated by the components in the box will be discharged from the heat dissipation holes at the dust screen under the impact of the cold air flow, and part of it will enter the inner cavity of the installation shell through the heat dissipation exhaust pipe, and then be cooled by the cooling pipe and driven by the fan blades to form a cold air flow into the box, and the cycle will be repeated, thereby efficiently dissipating the heat of the inner cavity of the box 1.

[0025] In order to improve the fixation of the installation box 701, as Figure 6 As shown: a fixing mechanism 11 is also provided at the installation box 701, and the fixing mechanism 11 includes a fixing rod 1101, a fixing block 1102 and a limiting block 1103; the fixing block 1102 is fixedly installed on one side of the installation box 701, and a groove is provided in the center of the fixing block 1102; the inner end of the fixing rod 1101 is movably installed in the groove of the fixing block 1102, and the limiting block 1103 passes through the fixing rod and the side wall of the fixing block to complete the limiting operation of the fixing rod 1101, thereby fixing the installation box 701.

[0027] like Figure 2 As shown: In order to effectively reduce voltage fluctuations and flickers, protect power equipment from damage, improve the stability and reliability of the power system, and then complete the refined voltage regulation of the output voltage, the high energy efficiency of the voltage regulator is achieved, which is more practical. In this embodiment, a power distribution module 14 is also provided in the box 1, wherein the power distribution module uses an RS485 communication interface for signal transmission. Figure 7 As shown: the power distribution module 14 includes a voltage signal acquisition unit 141, a signal processing unit 142, an algorithm processing unit 143 and a voltage regulation feedback unit 144; the voltage signal acquisition unit 141 is used to acquire the corresponding voltage signal parameters of the access grid; the signal processing unit 142 is used to pre-process the signal data collected by the voltage signal acquisition unit by filtering and removing noise; the algorithm processing unit 143 is used to complete the control and adjustment of the access side grid voltage and the output side voltage fluctuation adjustment correction by optimizing and upgrading the algorithm formula, and finally calculate the distribution correction adjustment amount of the corresponding grid voltage; the voltage regulation feedback unit 144 is used to complete the final correction processing and voltage stabilization operation of the output voltage through the distribution correction adjustment amount.

[0028] The algorithm formula of the algorithm processing unit 143 uses proportional-integral-differential control technology to adjust the speed of the servo motor inside the voltage regulator, and can stably adjust the output voltage according to the dynamic response difference of the previous and next grid voltage fluctuations. The formula is as follows:

[0029] Among them, D(t) is the output of the servo motor control in the voltage regulator, that is, the voltage adjustment; the grid access voltage fluctuates, that is, it is too high or too low; when the grid access voltage is too high, D(t) is a negative value to reduce the voltage. When the grid access voltage is too low, D(t) is a positive value to increase the voltage; x(t) is the system error, that is, the dynamic response difference of the grid voltage fluctuation before and after. Kp , Ki , Kd They are proportional, integral and differential coefficients respectively.

[0030] At the same time, in order to better and intuitively observe the voltage regulator, an LED display screen 15 is also provided on the outside of the box 1, and the LED display screen 15 maintains a signal connection with the power distribution module 14 to complete the display of the voltage parameter waveform and the data display of the voltage real-time detection parameters and correction coefficients. In order to better store data and facilitate subsequent data calls and viewing, it is further preferred that the power distribution module 14 also includes a data storage module 147, which is used to record and store the collected voltage signal parameters in units of days and in the form of an Excel table.

[0031] In order to better connect and install the power distribution module and to facilitate the subsequent detachable upgrade of the system and control functions, in a preferred embodiment, a protective shell 16 is also provided around the power distribution module 14 to protect the power distribution module. A mounting block 17 is provided on one side of the box body 1. Figure 8 As shown: the installation block 17 is mainly composed of a bottom plate 171, a side plate 172 and a back plate 173. Specifically, the bottom plate 171 is distributed on the left and right, and the side plates 172 are symmetrically distributed and arranged on the upper and lower sides of the bottom plate 171. The back plate 173 is arranged on the rear side of the bottom plate 171. A communication connector 146 connected to the voltage regulator body is arranged on one side of the center of the back plate 173. The communication connector 146 is connected to the communication interface 147 provided on the power distribution module 14 to maintain signal transmission, and the bottom plate 171, the side plate 172 and the back plate 173 are integrally formed. The installation cavity enclosed by the bottom plate 171, the side plate 172 and the back plate 173 is adapted to install the power distribution module.

[0032] Among them, a guide structure 18 is also provided between the protective shell 16 and the mounting block 17, and the guide structure 18 includes a guide plate 181 and a guide rail 182; the guide plate 181 is fixedly installed on the protective shell 16, and the guide rails 182 are three and are respectively arranged on the bottom plate 171 and the two side plates 172, and the guide plate 181 is matched with the guide rails 182. The purpose of such a setting is to ensure the guiding accuracy of the connection and facilitate installation and disassembly and replacement. At the same time, in order to further ensure the stability of the connection between the communication connector and the communication interface, such as Fig. 9 As shown: a fastener 19 is also provided on the mounting block 1; the fastener 19 includes a fastener rod 191, a spring 192, a compression spring 193 and a pull ring 194; the fastener rod 191 is movably arranged up and down through the side plate 172, and the lower part of the fastener rod 191 is provided with an outwardly distributed inclined surface 195.

[0033] like Fig. 9As shown: wherein, the spring 192 is arranged on the back plate 173 for buffering connection. The pull ring 194 is arranged at the end of the fixing rod 191, and the compression spring 193 is arranged on the fixing rod 191 and is located outside the side plate 172. One end of the compression spring 193 is connected to the fixing rod 191 and the other end is connected to the side plate 172. The purpose of such arrangement is that in the initial state, the spring 192 and the compression spring 193 are naturally extended, and the fixing rod 191 forms a barrier to the entry of the distribution module. When the distribution module enters the installation cavity so that the communication interface is connected to the communication connector, the protective shell 16 of the distribution module first contacts the inclined surface 195 to form an extrusion on the fixing rod 191. Specifically, the fixing rods 191 distributed on the upper and lower sides are driven to move outward at the same time, and the compression spring 193 begins to be compressed and stored until the communication interface and the communication connector are in a tightly connected state. At this time, the protective shell 16 of the distribution module completely enters the installation cavity, and the spring 192 is compressed and stored. At the moment when the distribution module 14 and the fastening rod 191 are misaligned, the fastening rod 191 is quickly reset under the action of the energy release of the compression spring 193, forming a block for the distribution module 14 and the protective shell 16 as a whole, further ensuring the stability of the connection of the distribution module. At the same time, when the distribution module needs to be repaired or the system needs to be upgraded, it is only necessary to manually pull the pull ring 194 so that the fastening rod 191 unlocks the block on the distribution module, and the internal spring 192 releases energy to easily drive the distribution module to move outward a preset distance, and then the staff can manually and easily pull out the protective shell of the distribution module. Among them, the elastic force of the spring 192 is large enough to open the connection between the communication interface and the communication connector.

[0034] The working principle of the present invention is as follows: the purpose of heat dissipation and water cooling is to ensure the stability and safety of the working state of the voltage regulator.

[0035] When the voltage regulator adjusts the fluctuation of the grid access voltage, the voltage signal parameters of the corresponding grid access are first collected through the voltage signal acquisition unit; the voltage is the real-time voltage accessed by the voltage regulator. In the next step, the signal data collected by the voltage signal acquisition unit is filtered and denoised by the signal processing unit; thereby ensuring that only the voltage signal parameters are recorded. Then, the algorithm processing unit completes the control and adjustment of the grid voltage on the access side and the voltage fluctuation adjustment correction on the output side by optimizing and upgrading the algorithm formula, and finally calculates the distribution correction adjustment amount of the corresponding grid voltage; wherein D(t) is the output of the servo motor control in the voltage regulator, that is, the voltage adjustment amount. The grid access voltage fluctuates, that is, it is too high or too low; when the grid access voltage is too high, D(t) is a negative value for voltage reduction and stabilization. When the grid access voltage is too low, D(t) is a positive value for voltage increase and stabilization. The present invention ensures that the voltage fluctuates within a set range by monitoring the voltage and adjusting it in real time; when the load of the power system changes, the voltage regulator can automatically adjust the output voltage to adapt to the change in load. This helps prevent the voltage from being too high or too low, thereby protecting equipment from damage; by adjusting the voltage, it can help each part of the power grid maintain the same frequency and phase, which is essential for the stable operation of the power grid; at the same time, by maintaining voltage stability, the voltage regulator helps reduce losses in the power system; voltage that is too high or too low will lead to increased power losses, and the voltage regulator can reduce these losses by adjusting the voltage.
