Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The output power adjusting method provided by the embodiment of the application can be applied to the application environment shown in fig. 1. The input end of the socket is connected with a bus of a power supply network, and the output end of the socket is connected with a load. The socket may be a dc socket, and the types of the sockets include, but are not limited to, 86 type, 118 type, and 120 type, and the like. The load may be various electric appliances without power regulator, such as refrigerator, cold drink machine, electric fan, washing machine, dust collector, microwave oven, electric cooker, dish washer, hair drier, hair styler, TV set, computer, etc.
It can be understood that the output power adjusting method provided in the embodiment of the present application may be implemented by disposing a power adjusting device made of a power electronic device in the socket, where the power adjusting device has a function of continuously detecting a bus voltage of the socket, and the socket detects an initial bus voltage each time the socket is powered on again, and uses the currently detected bus voltage as a reference to make an adjustment basis, and automatically adjusts an output ratio through a change in a bus voltage amplitude, and can adjust the output power of the socket according to a change amplitude of the detected bus voltage value and the initial powered-on voltage value of the socket.
In practical application, the socket can be applied to a light storage direct-flexible system, so that flexible control of part of storage electric equipment can be realized through the power adjusting function of the socket, and the control requirement of an Energy Management System (EMS) is met.
The following describes an implementation process of the output power adjustment method provided in the embodiments of the present application with specific embodiments. As shown in fig. 2, in one embodiment, the process of output power adjustment includes the following steps:
and S101, detecting the current bus voltage of the target socket.
A target outlet generally refers to any outlet that requires output power regulation. Optionally, the destination socket is a dc socket. The bus voltage is the voltage on the bus to which the socket input is connected.
In an embodiment, taking the power adjusting device manufactured by arranging a set of power electronic devices in the socket as an example, the power adjusting device is provided with a function of continuously detecting the bus voltage of the socket, so as long as the target socket is in a power-on state, the voltage of the target socket at each moment can be detected, and the bus voltage at the current moment is the current bus voltage of the target socket.
In another embodiment, the current bus voltage of the target socket may be detected by a bus voltage transformer.
S102, acquiring a voltage change value of the bus voltage of the target socket according to the current bus voltage and the initial bus voltage; the initial bus voltage is the voltage at which the target receptacle is powered on.
Based on the detected current bus voltage of the target socket, the voltage change value of the bus voltage of the target socket can be obtained by combining the initial bus voltage when the target socket is powered on.
In practical application, the target socket has a power-on and power-off period, and each period has only one initial bus voltage. For example, the target outlet is powered off at time X1 and powered back on at time X2, and the initial bus voltage of the target outlet is the bus voltage at time X2. The initial bus voltage may be understood as the default voltage of the target outlet.
The voltage change value of the bus voltage of the target outlet refers to a voltage change magnitude between the current voltage value and the initial bus voltage. The difference between the current bus voltage and the initial bus voltage is the voltage variation value, for example, the current bus voltage is the voltage at the time of N, which is represented as UNThe initial bus voltage is denoted as U1Then the voltage variation value US＝UN-U1。
It can be understood here that, from the dimension of the current bus voltage relative to the initial bus voltage, the voltage change value has both positive and negative conditions, and the positive and negative conditions represent two trends of the current bus voltage to rise and fall relative to the initial bus voltage.
And S103, if the voltage change value meets the preset adjustment condition, adjusting the output power of the target socket to be the target output power according to the voltage change value and the initial bus voltage.
And determining a voltage change value of the current bus voltage relative to the initial bus voltage, and analyzing whether the voltage change value meets a preset adjustment condition or not by taking the voltage change value as a judgment basis. The preset adjusting condition is preset and is used for measuring whether the output power of the target socket is adjusted.
In one embodiment, if the voltage variation value is greater than the voltage threshold, and the duration that the voltage variation value is greater than the voltage amplitude reaches the duration threshold, it is determined that the voltage variation value satisfies the preset adjustment condition.
The method comprises the steps of presetting a voltage threshold and a time threshold, analyzing whether the voltage change value is greater than the voltage threshold or not, and analyzing whether the duration of the greater voltage change value exceeds the time threshold, and if so, determining that the voltage change value meets preset adjustment conditions. Otherwise, determining that the voltage change value does not meet the preset adjustment condition.
For example, a voltage threshold of UYWith a time threshold of TYThen if US＞UYAnd TUS＞UYDuration of > TYThen determine USAnd the preset adjustment condition is met. It should be noted that the absolute value of the voltage change value is analyzed when the preset adjustment condition is determined. Therefore, whether the current bus voltage is rising or falling relative to the initial bus voltage, the preset adjustment condition is determined to be met as long as the absolute value of the difference between the two is greater than the voltage threshold and the duration of the greater is greater than the duration threshold.
In one embodiment, the voltage threshold is determined according to the initial bus voltage and a predetermined factor.
The voltage threshold may be the product of the initial bus voltage and a predetermined coefficient, or the initial bus voltage and a predetermined coefficientThe difference between the coefficients may also be a ratio of the initial bus voltage to a preset coefficient, and the like, which is not limited in the embodiment of the present application. Taking the product as an example, if the predetermined coefficient is 1.5%, the voltage threshold U is setYInitial bus voltage U1A predetermined factor of 1.5%.
After the voltage change value is determined to meet the preset adjusting condition, the output power of the target socket can be adjusted to be the target output power according to the voltage change value and the initial bus voltage. The target output power represents the power adjusted for the power output by the target outlet.
The voltage output by the target socket can be controlled to be a target output voltage by adjusting the output power of the target socket to be the target output power, and the target output voltage can enable the output power of the target socket to be equal to the target output power; or controlling the voltage output by the target socket to be a target output current, wherein the target output current is in a size which can enable the output power of the target socket to be equal to the target output power.
Taking the voltage as an example, an output voltage can be calculated as a target output voltage according to the voltage variation value and the initial bus voltage, and the voltage output by the target socket is controlled to be the target output voltage, which is an equivalent voltage of the target output power.
In the embodiment of the application, the current bus voltage of the target socket is detected, the voltage change value of the bus voltage of the target socket is obtained according to the current bus voltage and the initial bus voltage when the target socket is powered on, and when the voltage change value meets the preset adjustment condition, the output power of the target socket is adjusted to be the target output power according to the voltage change value and the initial bus voltage. In the method, the bus voltage of the target socket at the current moment is detected in real time, the initial voltage value during power-on is taken as a default voltage value, and equivalently, the output power of the target socket is adjusted when the change amplitude between the bus voltage at the current moment and the default voltage value meets the set adjustment condition based on the bus voltage at the current moment. The output power of the target socket is adjusted according to the change of the direct-current bus voltage of the target socket, so that the flexible adjusting function of a load connected with the target socket can be achieved through the target socket, and flexible interaction between the load and a power supply network is achieved.
Based on the above embodiments, the process of adjusting the output power of the target outlet to the target output power according to the voltage variation value and the initial bus voltage will be described.
In one embodiment, as shown in fig. 3, the step S103 includes the following steps:
s201, acquiring the variation trend of the voltage variation value according to the current bus voltage and the initial bus voltage.
As mentioned previously, the sign of the voltage change value represents two trends of the current bus voltage rising and falling relative to the initial bus voltage. Namely, if the current bus voltage is greater than the initial bus voltage, determining that the change trend is an ascending trend; and if the current bus voltage is less than the initial bus voltage, determining that the change trend is a descending trend.
S202, determining a target output voltage according to a proportional calculation relation corresponding to the change trend, the voltage change value and the initial bus voltage; the proportional calculation relation includes a preset voltage output proportion.
In this embodiment, the output power of the target outlet is adjusted by adjusting the output voltage of the target outlet. Generally, the output voltage of the socket has a certain loss with the input voltage of the socket, so that the output voltage of the socket has a certain proportional relation with the input voltage.
Based on this, determining the target output voltage of the target socket requires determining the voltage output ratio required for adjusting the output power of the target socket.
And aiming at the variation trends of different voltage variation values, a proportional calculation relational expression corresponding to each variation trend can be preset, and the target output voltage required to be adjusted can be calculated by combining the voltage variation value and the initial bus voltage according to the proportional calculation relational expression.
Wherein, the preset proportion calculation relation includes a preset voltage output proportionThe default bus voltage is the ratio of the voltage that the target outlet is allowed to output. For example, the default bus voltage is the initial bus voltage ═ U1If the predetermined voltage output ratio is 60%, the voltage U output from the target socket is allowedO0＝U1*60％。
It should be noted that the voltage U allowed to be output from the target outletO0Also referred to as the initial output voltage in the embodiments of the present application, it represents the output voltage at which the target outlet is powered on.
It should be noted that, for different variation trends of the voltage variation value, the determined target output voltage has different magnitude relative to the initial output voltage. Optionally, if the variation trend is an ascending trend, the target output voltage is greater than the initial output voltage; and if the variation trend is a descending trend, the target output voltage is smaller than the initial output voltage.
It can be illustrated that, in the embodiment of the present application, the trend of change of the determined target output voltage with respect to the initial output voltage is the same as the trend of change of the voltage change value. That is, from the control requirement dimension of an Energy Management System (EMS), if the current bus voltage is decreased with respect to the initial bus voltage, it is considered that the EMS energy management system requires a decrease in output power of the target outlet, and if the current bus voltage is increased with respect to the initial bus voltage, it is considered that the EMS energy management system requires an increase in output power of the target outlet. And the proportion of decrease or increase may be determined by the magnitude of change in the current bus voltage relative to the initial bus voltage decrease or increase.
And S203, adjusting the output voltage of the target socket to be the target output voltage, so that the output power of the target socket is the target output power.
And after the target output voltage is determined, controlling the output voltage of the target socket to be the target output voltage. Since the target output voltage is determined based on the voltage change value of the current bus voltage with respect to the initial bus voltage, the target output power equivalent to the target output voltage is also determined based on the voltage change value, and thus the function of adjusting the output power of the outlet in accordance with the change in the dc bus voltage of the outlet is realized in the target outlet. Then a flexible adjustment of the load is achieved for the load connected to the target outlet.
In the embodiment of the application, the variation trend of the voltage variation value is obtained according to the current bus voltage and the initial bus voltage, the target output voltage is determined according to the proportional calculation relation corresponding to the variation trend, the voltage variation value and the initial bus voltage, and then the output voltage of the target socket is adjusted to be the target output voltage, so that the output power of the target socket is the target output power. In the method, the target output voltage after adjustment of the target socket can be calculated by combining the change trend of the bus voltage and the proportional calculation relational expression, which is equivalent to the target output power which is equivalent to the target output voltage by adjusting the output voltage of the socket according to the change of the direct current bus voltage of the socket, so that the output voltage of the target socket is adjusted to the target output voltage, and the function of adjusting the output power of the socket according to the change of the direct current bus voltage of the socket is realized. Therefore, the target socket can realize the flexible adjustment function of the load, thereby realizing the flexible interaction of the load and the power supply network.
The following describes a process of calculating the target output voltage in two cases, i.e., an upward trend and a downward trend.
In one embodiment, as shown in fig. 4, the process of determining the target output voltage if the trend of change is an ascending trend includes the following steps:
and S301, determining a voltage increase ratio through the increase ratio relation and the voltage change value.
And S302, determining a target output voltage according to the voltage increase proportion and the initial bus voltage.
In this embodiment, if the variation trend is an ascending trend, the corresponding proportional calculation relation is set as an increasing proportional relation. The voltage increase ratio may be determined by the increase ratio relation and the voltage variation value, and the target output voltage may be determined according to the voltage increase ratio and the initial bus voltage.
For example, the increasing proportional relation is: voltage increase ratio is a preset voltage output ratioA percentage of the sum of two times the voltage change value; then, the voltage increase proportion P calculated by the increase proportion relation and the voltage change value USU＝(60+2|US|)％。
Further, the product of the voltage increase proportion and the initial bus voltage may be determined as the target output voltage. I.e. the target output voltage UOn＝U1*PU＝U1*(60+2|US|)％。
In another embodiment, as shown in fig. 5, if the trend of change is a downward trend, the process of determining the target output voltage includes the following steps:
s401, determining a voltage reduction ratio through a reduction ratio relation and a voltage change value.
S402, determining a target output voltage according to the voltage reduction proportion and the initial bus voltage.
And if the change trend is a descending trend, setting the corresponding proportional calculation relation as a descending proportional relation. The voltage reduction ratio may be determined by the reduction ratio relation and the voltage change value, and the target output voltage may be determined according to the voltage reduction ratio and the initial bus voltage.
For example, the decreasing ratio is: the voltage increase proportion is the percentage of the difference between the preset voltage output proportion and the voltage change value; then, the voltage reduction ratio P calculated by the reduction ratio relation and the voltage change value USD＝(60-|US|)％。
Further, the product of the voltage reduction ratio and the initial bus voltage may be determined as the target output voltage. I.e. the target output voltage UOn＝U1*PU＝U1*(60-|US|)％。
In the above embodiment, the target output voltages under different variation trends are calculated through different proportional calculation relations according to different variation trends of the voltage variation value, so that after the output voltage of the target socket is adjusted to the target output voltage, the output voltage can be automatically adjusted according to the bus voltage value during initial power-on, and different adjustment ranges and user personalized requirements are automatically adapted, so that the output voltage adjusted by the target socket meets the control requirement of the energy management system, and the flexible interaction capacity of the load and the power supply network is improved.
The above embodiments are all directed to the case where the voltage variation value satisfies the preset adjustment condition. In one embodiment, if the voltage variation value does not satisfy the preset adjustment condition, the output voltage of the target socket is adjusted to be the initial output power; the initial output power is a power determined according to an initial output voltage when the target outlet is powered on. Optionally, the initial output power is determined according to a preset initial output proportion and an initial bus voltage.
Whether the current bus voltage is increased or decreased relative to the original bus voltage, the current bus voltage is necessarily recovered after a certain period of time, or the amplitude of the increase or decrease of the current bus voltage is very small. For these cases, it is detected that the voltage variation value of the current bus voltage with respect to the initial bus voltage does not necessarily satisfy the preset adjustment condition. For example, if the voltage variation value is less than 1.5% (voltage threshold) of the initial bus voltage and the duration reaches the duration threshold, it is determined that the voltage variation value does not satisfy the preset adjustment condition.
And if the voltage change value does not meet the preset adjustment condition, the output voltage of the target socket can be adjusted to be the initial output power. The initial output power is the equivalent power of the initial output voltage, and the initial output voltage is the default output voltage, which may be the product of the preset initial output proportion and the initial bus voltage.
In the embodiment of the application, under the condition that the voltage change value does not meet the preset adjustment condition, the output voltage of the target socket is adjusted to be the default initial voltage, so that the default output power is recovered when the output power does not need to be adjusted, and the flexible adjustment reliability of the load connected to the target socket is ensured.
Considering that in some scenarios, flexible adjustment of the load is not required, in the target outlet, an adjustment switch may be provided, which may be used to turn off the flexible adjustment function of the target outlet. In one embodiment, as shown in fig. 6, the method further comprises:
s501, detecting whether a target socket receives a power adjustment starting instruction; the power adjustment turn-on command is triggered by user interaction with an adjustment switch on the target outlet.
And S502, if the power adjustment starting instruction is received, executing the step of detecting the current bus voltage of the target socket.
The adjusting switch can be a physical key, a touch screen switch, a switch supporting recognition modes such as voice, human face and limbs, a remote control type control switch and the like, and the implementation mode of the adjusting switch is not limited in the embodiment of the application.
And the user starts to execute the step of detecting the current bus voltage of the target socket if detecting that the target socket receives the power adjustment starting instruction, namely, the function of adjusting the output power of the target socket is started.
In this embodiment, the output power of the target socket is adjusted and can be turned on according to the power adjustment turn-on instruction, so that the flexible adjusting function of the target socket is turned on preferentially according to the will of the user, and the intelligence of the target socket is improved.
As shown in fig. 7, there is also provided an output power adjustment method, including:
and S1, powering on the target socket for starting.
S2, detecting the initial bus voltage U1。
S3, determining default allowable output UO0＝U1×60％。
And S4, detecting the current bus voltage Un of the target socket at regular time.
S5, calculating the difference value Us ═ U1-Un。
S6, determine whether Us >0.015 × U1, if so, execute S7, and if not, execute S8.
S7, adjusting output voltage Uon ═ U of target socket1×(60-Us)％。
S8, continuing to read Us < -0.015 × U1, if the result is S9, otherwise, executing S10.
S9, adjusting the targetOutput voltage Uon ═ U of socket1×(60+2*|Us|)％
S10, output voltage Uo ═ Uo of target socket0。
Specifically, when the bus voltage value decreases to be greater than the default voltage value (initial bus voltage U)1) 1.5% of the total output voltage, and the duration reaches a specified value, it is considered that the Energy Management System (EMS) requires to reduce the output power, the reduction ratio of which is related to the given voltage reduction amplitude, at this time, the dc outlet implements an output power adjustment strategy by controlling the output percentage of the electronic switch, thereby adjusting the output voltage value; the DC socket completes the storage of default voltage values and the setting of default output percentage according to the voltage values detected during electrification, and when the voltage value of the bus is recovered to be within 1.5 percent of the default value and the duration time reaches a specified value, the DC socket recovers to default output (UO)0)。
