Attached Figure Description
[0043] Figure 1 A flowchart of a power distribution network installation optimization method for a magnetically controlled transformer is provided as an embodiment of the present invention;
[0044] Figure 2 This is a schematic diagram of a power distribution network installation optimization system for a magnetically controlled transformer, provided as an embodiment of the present invention. Detailed Implementation
[0045] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0046] The present invention provides a method for optimizing the installation of a magnetically controlled transformer in a power distribution network, wherein the magnetically controlled transformer includes a magnetically controlled reactor assembly and a transformer assembly, and the magnetically controlled reactor assembly is connected to the core columns of the transformer assembly to form a set of core columns.
[0047] It should be noted that the magnetically controlled transformer in this embodiment is a compact magnetically controlled transformer, which integrates the magnetically controlled reactor assembly and the transformer assembly into one unit. The core columns of the magnetically controlled reactor assembly and the transformer assembly are fused into a single set of core columns. Structural optimization makes the component layout more compact, thus significantly reducing its size compared to separate magnetically controlled reactor assemblies and transformer assemblies. The compact magnetically controlled transformer with the same capacity and turns ratio is only slightly larger than a traditional transformer assembly, approximately 1.5 times the size.
[0048] For easier understanding, please refer to Figure 1 The present invention provides a method for optimizing the installation of magnetically controlled transformers in power distribution networks, comprising the following steps:
[0049] S1. Obtain the peak power and power factor time-series data of the power distribution network in the target area within a preset time period.
[0050] The preset time period is the maximum rated service life of the magnetically controlled transformer (which can be obtained from the manufacturer's nameplate of the magnetically controlled transformer).
[0051] S2. Based on the time-series data of peak power consumption and power factor, predict the maximum peak power consumption and the minimum power factor within the same preset time period in the future.
[0052] One possible prediction method is to use a trained long short-term memory network model for time series prediction, such as the LSTM model.
[0053] The LSTM model predicts all peak power and power factor time series data within the same preset time period in the future based on peak power and power factor time series data. Outliers are removed from all peak power and power factor time series data within the same preset time period in the future, and the maximum peak power and the minimum power factor (i.e., the maximum reactive power compensation demand) are selected.
[0054] S3. Determine the minimum rated capacity of the magnetically controlled transformer by the maximum peak power consumption and the minimum power factor, and determine the maximum rated capacity of the magnetically controlled transformer based on the maximum power that can be connected to the distribution network, thereby determining the rated capacity range of the magnetically controlled transformer.
[0055] The rated capacity range of magnetically controlled transformers mainly takes into account the power consumption and reactive power compensation requirements of the user side.
[0056] In practical applications, the apparent power of a magnetically controlled transformer is determined by the maximum peak power consumption and the minimum power factor. Since there are iron losses, copper losses, and losses caused by aging during the operation of the magnetically controlled transformer, the capacity of the transformer components will be reduced. This factor needs to be taken into account in the capacity selection scheme. The capacity selection of the magnetically controlled transformer should have redundancy in the apparent power of the magnetically controlled transformer calculated by taking into account the above factors. That is, the apparent power of the magnetically controlled transformer should be the minimum capacity constraint of the magnetically controlled transformer.
[0057] Simultaneously, the maximum accessible power at the transformer assembly installation location is obtained. The total planned capacity of the magnetically controlled transformers should not exceed the maximum accessible capacity, i.e., the maximum accessible capacity is the highest capacity constraint for the magnetically controlled transformers. If the highest capacity constraint is less than the lowest capacity constraint, the highest capacity constraint prevails, and magnetically controlled transformers are selected to be installed in other areas until the voltage and power factor of the regional distribution network can be maintained to meet user needs.
[0058] S4. Determine the number of turns of the core coil of the magnetically controlled transformer based on the rated capacity range of the magnetically controlled transformer.
[0059] It should be noted that when designing the core coil turns parameters of a magnetically controlled transformer, it is necessary to determine them according to the rated capacity range of the magnetically controlled transformer, so as to obtain the required inductance value and transformer component turns ratio, so that the output voltage and reactive power compensation capacity of the magnetically controlled transformer meet the target requirements.
[0060] In practical applications, the losses of magnetically controlled transformers during operation must be minimized. The main influencing factors include iron losses and copper losses in the transformer assembly, as well as losses from auxiliary equipment (such as fans, cooling devices, and control circuits). These losses can be reduced by adjusting the core material of the transformer assembly, the coil winding method, and optimizing the topology during the design of the magnetically controlled transformer. In addition, load losses of the transformer assembly should be reduced. The main methods include avoiding overloading or underloading the transformer assembly and keeping it within its rated load range. For magnetically controlled transformers, both the transformer assembly and reactor components should operate under suitable load conditions. The standard loss of a magnetically controlled transformer should be less than the sum of the losses of a magnetically controlled reactor assembly of the same capacity and the losses of a transformer assembly of the same capacity.
[0061] Due to the saturation stage of the solenoid valve, magnetically controlled transformers may generate harmonics, degrading the power quality of the distribution network. Therefore, in the design of magnetically controlled transformers, the solenoid valve structure can be optimized to avoid harmonic interference to the distribution network during operation. Reducing losses and harmonics helps improve the operating efficiency of magnetically controlled transformers, reduces the energy consumption of the power grid, and has positive significance for resource conservation and environmental protection.
[0062] S5. Determine the installation location of the magnetically controlled transformer based on the power distribution network and load distribution in the target area, so that the working radius of the magnetically controlled transformer does not overlap with other transformer components.
[0063] It should be noted that the size of a magnetically controlled transformer is usually directly related to the capacity of the transformer assembly; larger capacity transformer assemblies require more installation space. Because magnetically controlled transformers are compact, the size of a compact magnetically controlled transformer with the same capacity and turns ratio is only slightly larger than that of a traditional transformer assembly, approximately 1.5 times that of a traditional transformer assembly.
[0064] Therefore, it is necessary to customize corresponding standards for the volume and floor space of magnetically controlled transformers to guide their installation. Once the size of the magnetically controlled transformer is determined, it must be submitted to the relevant departments for review, and the volume of transformer components must be managed in accordance with relevant power industry standards, including requirements for the volume and dimensions of transformer components, to ensure the safe and reliable operation of the transformer components.
[0065] One approach is to use traditional load distribution patterns to select the installation location of the magnetically controlled transformer. Alternatively, a virtual visual image 3D sampling model can be used to model the power distribution network (transformer components) and load distribution in the target area's power distribution network and simulate the coupling effect of each transformer component. This allows for the selection of the installation location of the magnetically controlled transformer within the simulation model, ensuring that the working radius of the magnetically controlled transformer does not overlap with other transformer components.
[0066] To ensure insulation between critical components of the transformer assembly, the distances between these components must meet the required insulation safety distances. Sufficient installation space must also be provided for auxiliary equipment that assists in the safe and stable operation of the transformer assembly, such as fans, cooling devices, and control circuits. Sufficient space must also be provided for ventilation to facilitate heat dissipation from the transformer assembly.
[0067] Meanwhile, the magnetically controlled transformer can be installed in multiple locations, ensuring that its working radius does not overlap with other transformer components, and allowing for the selection of the optimal installation location.
[0068] The working radius of a magnetically controlled transformer is also its coupling radius. When installing transformer components in a regional power distribution network, the coupling effect between transformer components installed in different locations should be reasonably calculated to prevent excessive overlap of working radii.
[0069] It should be noted that transformer assemblies should generally be located close to the load center to meet the requirements of safe and convenient operation and maintenance. Magnetic-controlled transformers have reactive power compensation capabilities; therefore, areas in the power supply network with high reactive power generation and severe power factor degradation should be considered for the installation of magnetic-controlled transformers. Due to increased transmission distance, increased line resistance leads to voltage drops and power losses, and the operating radii of transformer assemblies of different capacities also vary. When installing transformer assemblies in a regional distribution network, the coupling effect between transformer assemblies installed in different locations should be reasonably calculated to prevent excessive overlap of operating radii.
[0070] In practical applications, after determining the approximate location of the magnetically controlled transformer in the line, the following considerations should be taken into account when selecting a site:
[0071] According to the land use plan of the city or region, the types and uses of construction land in different areas are specified. The installation of transformer components must comply with the requirements of the land use plan, such as not violating the land use regulations for residential areas.
[0072] The installation location for a magnetically controlled transformer should be a dry, well-ventilated place free from corrosive gases and dust, and away from flammable or other hazardous substances. Avoid installation in locations susceptible to impact, vibration, and magnetic field interference.
[0073] Magnetic control transformers can affect the surrounding environment. It is important to avoid the adverse effects of noise and electromagnetic radiation on nearby residents, the environment, and animals.
[0074] S6. After installing the magnetically controlled transformer in the installation location, put it into use.
[0075] It should be noted that this invention determines the minimum rated capacity of the magnetically controlled transformer by predicting the maximum peak power consumption and the minimum power factor within a preset future time period, and determines the maximum rated capacity of the magnetically controlled transformer based on the maximum accessible power of the distribution network, thereby determining the rated capacity range of the magnetically controlled transformer. Based on the rated capacity range of the magnetically controlled transformer, the number of coil turns of the magnetically controlled transformer is determined. Based on the power distribution network and load distribution in the target area, the installation location of the magnetically controlled transformer is determined. After the magnetically controlled transformer is installed in the installation location, it is put into use. This approach takes into account the actual needs of users and the distribution network, ensuring the power quality of the regional distribution network and resulting in better performance after the magnetically controlled transformer is put into use.
[0076] In one specific embodiment, step S3 specifically includes:
[0077] 301. Determine the minimum rated active power capacity of the transformer components in a magnetically controlled transformer by the maximum peak power consumption.
[0078] The maximum peak power consumption is the minimum rated active power capacity of the transformer components in the magnetically controlled transformer.
[0079] 302. Determine the minimum reactive power compensation capacity of the magnetically controlled reactor assembly in the magnetically controlled transformer based on the minimum rated active power capacity and the minimum power factor.
[0080] The reactive power can be calculated based on the minimum rated active power capacity and the minimum power factor. The reactive power is the minimum reactive power compensation capacity of the magnetically controlled reactor assembly in the magnetically controlled transformer.
[0081] 303. Determine the minimum rated capacity of the magnetically controlled transformer based on the minimum rated active capacity and the minimum reactive power compensation capacity.
[0082] The minimum rated capacity of a magnetically controlled transformer is the open root of the sum of the square of the minimum rated active capacity and the square of the minimum reactive power compensation capacity.
[0083] 304. Determine the maximum rated capacity of the magnetically controlled transformer based on the maximum power that can be connected to the distribution network.
[0084] The maximum accessible power of the distribution network can be obtained through big data analysis of the distribution network, which is the maximum rated capacity of the magnetically controlled transformer.
[0085] 305. Determine the rated capacity range of the magnetically controlled transformer based on its minimum and maximum rated capacity.
[0086] In one specific embodiment, step S4 specifically includes:
[0087] 401. Determine the minimum and maximum core cross-sectional areas of the magnetically controlled transformer based on its minimum and maximum rated capacities.
[0088] The maximum rated voltage, minimum rated voltage, maximum rated current, and minimum rated current can be determined by the minimum rated active power capacity and minimum reactive power compensation capacity of the magnetically controlled transformer. Based on the maximum rated voltage, minimum rated voltage, maximum rated current, and minimum rated current, the core cross-sectional area of the magnetically controlled transformer can be calculated using the following formula:
[0089]
[0090] In the formula, S represents the cross-sectional area of the iron core, K represents the coefficient, which is generally taken as 1 to 1.2, U represents the rated voltage, and I represents the rated current.
[0091] 402. Calculate the minimum and maximum number of coil turns of the magnetically controlled transformer based on the minimum and maximum core cross-sectional areas, thereby determining the range of coil turns for the magnetically controlled transformer.
[0092] The formula for calculating the number of coil turns is as follows:
[0093] N = U / (4.44 × B × S × f)
[0094] In the formula, N represents the number of coil turns, B represents the magnetic saturation intensity of the iron core (usually around 1.4 for silicon steel sheets), and f represents the frequency (usually 50Hz).
[0095] The winding structure of the iron core is generally a circular winding around the iron core from top to bottom.
[0096] In one specific embodiment, before step S6, the method further includes:
[0097] 61. Conduct factory tests on the magnetically controlled transformer to determine whether it has passed the factory tests.
[0098] The factory testing includes voltage and current testing, active and reactive power capacity testing, and harmonic and loss testing. Voltage and current testing must ensure that the magnetically controlled transformer can output voltage and current at its rated value, with deviations meeting national safety standards (e.g., voltage fluctuations are allowed ±7% in a 10kV distribution network). Active and reactive power capacity testing must ensure that the transformer components, when operating at their rated power, can achieve rated output active power and reactive power compensation capacity. Harmonic testing must ensure that the output harmonics of the magnetically controlled transformer meet national safety standards. Loss testing must ensure that the losses of the magnetically controlled transformer during operation are less than the combined losses of a magnetically controlled reactor component of the same capacity and the losses of a transformer component of the same capacity.
[0099] If the magnetically controlled transformer fails the factory test, it needs to be remanufactured or optimized.
[0100] 62. If the magnetically controlled transformer is determined to have passed the factory test, then install the magnetically controlled transformer in the corresponding installation position.
[0101] It should be noted that the installation of magnetically controlled transformers must ensure an absolutely safe operating environment. The connection between the equipment and the foundation must be secure to prevent vibration, shaking, or other physical impacts. Connecting cables and wires must meet insulation standards and be connected according to the correct phase sequence, ensuring the magnetically controlled transformer is safely and reliably grounded. Fans, cooling systems, control circuits, and testing equipment must be installed in appropriate locations on the transformer assembly.
[0102] In one specific embodiment, step S6 specifically includes:
[0103] 601. After the magnetically controlled transformer is installed in the corresponding installation position, a safety test is conducted on the magnetically controlled transformer to determine whether the magnetically controlled transformer passes the safety test.
[0104] The safety tests include DC resistance testing, power factor testing, insulation resistance testing, transformer component open / short circuit testing, relay protection testing, and cooling system testing.
[0105] If the magnetically controlled transformer fails the safety test, then parameter optimization or structural optimization of the magnetically controlled transformer is required.
[0106] 602. If the magnetically controlled transformer is determined to have passed the safety test, then a grid-connected operation test shall be conducted on the magnetically controlled transformer to determine whether the magnetically controlled transformer has passed the grid-connected operation test.
[0107] The grid-connected operation test includes tests on the voltage fluctuation compensation and reactive power compensation effects of the distribution network. The presence of numerous power electronic devices and the grid connection of new energy sources cause grid voltage fluctuations and introduce a large amount of reactive power. Ensuring that the voltage quality on the user side meets national safety standards after the magnetically controlled transformer is connected to the grid is the primary indicator of this test.
[0108] If it is determined that the magnetically controlled transformer has failed the grid-connected operation test, then parameter optimization or structural optimization of the magnetically controlled transformer is required.
[0109] 603. If it is determined that the magnetically controlled transformer has passed the grid-connected operation test, then the magnetically controlled transformer shall be put into use.
