The scheme provided by the application is mainly aimed at controlling the compensation type alternating current voltage stabilizer. Fig. 1 is a schematic diagram of a compensated ac voltage regulator, where the voltage regulator includes a compensation unit and two compensation transformers (e.g., T2 and T3 in fig. 1), and the compensation unit is connected to a secondary winding of the compensation transformers. The compensation unit comprises a plurality of compensation switches (such as SCR 1-SCR 10 in FIG. 1), and different on-off state combinations of the plurality of compensation switches and a secondary winding of the compensation transformer form a plurality of compensation loops.
In the embodiment of the application, the voltage stabilizer based on the compensation of the silicon controlled rectifier (Silicon Controlled Rectifier, SCR) is applied to a bypass voltage stabilizing scene of the UPS, discrete voltage compensation is realized through the multi-level tap of the compensation transformer and the on-off combination of the SCR group, and each SCR comprises thyristors with opposite conducting directions. As shown in fig. 1, the secondary of the compensation transformer T2 has two taps and the secondary of the compensation transformer T3 has one tap. The SCR11 is a loop total compensation SCR, the SCR11 is disconnected before gear switching, a slow start resistor plays a role in buffering a transformer, and the SCRs 11 are turned on after the SCRs 1-10 are turned off. In fig. 1, the secondary tap of the compensation transformer and the SCR can form 15 different compensation loops, and correspondingly, 15-gear compensation voltages are generated.
The compensation principle of the compensation type ac voltage stabilizer is described in a specific embodiment: as shown in fig. 1, the three winding transformation ratios of the T2 transformer are 6.2:88:132, a part of the material; t3 compensation transformer transformation ratio 20:220. when the output voltage Uout is 220V, based on SCR comprising thyristors with opposite conducting directions, the T2 compensation transformer can generate seven kinds of compensation voltages of + -15.1V, + -10.4V, + -6.2V and 0V at the primary (6.2 turns of windings), and the T3 compensation transformer can generate three kinds of compensation voltages of + -20.0V and 0V at the primary (20 turns of windings), so that 15 kinds of voltage compensation can be composed. In other embodiments, the more compensation transformer windings, the more compensation gears.
In addition, in order to realize the output voltage closed-loop control, the available compensation gear (or grade) of the compensation type alternating current voltage stabilizer provided according to the specific embodiment is made into a table. For example, the topology of fig. 1 is divided into 15 steps in total according to the compensation voltage from low to high, the compensation level 1 corresponds to a minimum negative compensation voltage value of-35.1V, and the 15 steps corresponds to a maximum compensation voltage value of +35.1v, as follows:
table 1 Compensation level and Compensation Voltage relationship Table
In a specific embodiment, according to different load side power values, the capability of the slow start resistor to buffer the transformer is different, that is, the compensation type ac voltage stabilizer has a certain voltage stabilizing and adjusting function except the compensation unit. When the current control scheme for the compensation type alternating current voltage stabilizer relates to compensation control based on a mains supply input voltage value, the voltage stabilizing adjustment performance of the voltage stabilizer is ignored, and the phenomenon of overshoot of output voltage is caused.
The embodiment of the application aims to realize the rapid effect on the output voltage by carrying out compensation voltage regulation on the output voltage of the compensation type alternating current voltage stabilizer so as to ensure that the output voltage of the compensation type alternating current voltage stabilizer is stabilized near or equal to the target voltage.
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the following description will be made with reference to the accompanying drawings by way of specific embodiments.
Fig. 2 is a flowchart of an implementation of a method for controlling a compensated ac voltage regulator according to an embodiment of the present application, as shown in fig. 2, the method includes the following steps:
s201, obtaining the output voltage of the compensation type alternating current voltage stabilizer.
The execution body of the embodiment of the application is a controller connected with the compensation type alternating current voltage stabilizer. The voltage sensor is arranged at the output end of the compensation type alternating current voltage stabilizer to collect the output voltage of the compensation type alternating current voltage stabilizer, and the controller directly reads the voltage information collected by the voltage sensor.
S202, determining an absolute value of a difference value of the output voltage minus the target voltage.
The target voltage is the required voltage of the follow-up load circuit of the compensation type alternating current voltage stabilizer.
The degree to which the output voltage deviates from the target voltage can be determined from the absolute value of the difference of the output voltage minus the target voltage, facilitating the determination of a fast or slow tuning strategy based on the degree of deviation. Specifically, when the absolute value is large, the degree of deviation of the output voltage from the target voltage is large, and the output voltage adjusting efficiency can be improved by adopting a fast adjusting strategy; when the absolute value is smaller, the degree of deviation of the output voltage from the target voltage is smaller, and the slow adjustment strategy is adopted to ensure the output voltage adjustment accuracy and ensure that the output voltage is equal to or close to the target voltage.
S203, if the absolute value is larger than or equal to the first threshold value and smaller than the second threshold value, determining a target compensation level according to the current compensation level and the slow compensation scheme; and if the absolute value is greater than or equal to the second threshold value, determining a target compensation level according to the current compensation level and the quick compensation scheme.
The absolute value is the absolute value of the difference of the output voltage minus the target voltage of the compensation ac voltage stabilizer, and the difference is the difference of the output voltage minus the target voltage, and the absolute value is the absolute value of the difference of the output voltage minus the target voltage, under the condition that the following is not specifically described.
Wherein, different compensation grades correspond to different compensation voltages. The compensation grade span corresponding to the adjacent adjustment period determined by the fast compensation scheme is larger than or equal to the compensation grade span corresponding to the adjacent adjustment period determined by the slow compensation scheme, namely, when compensation adjustment is performed based on the fast compensation scheme, the compensation voltage value is larger than the slow compensation scheme.
In the implementation process, when the absolute value is detected to be greater than or equal to the first threshold value and smaller than the second threshold value at different moments, different on-off state combination modes of a plurality of compensation switches in a compensation unit of the compensation type alternating current voltage stabilizer are not fixed. Therefore, when the target compensation level is determined, the current compensation level at the current moment when the absolute value is larger than the first threshold value is detected, so that the adjustment is performed at the current compensation level, and the compensation voltage difference value corresponding to the compensation level before and after the adjustment is ensured to meet the adjustment requirement of the output voltage.
Taking the difference value of the output voltage minus the target voltage as 6.2V as an example for explanation, when the current compensation level of the compensation type alternating current voltage stabilizer is 8 levels, the table look-up table according to the table 1 shows that the target level is 7 levels, so that the requirement that the difference value of the output voltage minus the target voltage is 0V can be met; if the current compensation level of the compensation type ac voltage stabilizer is 7, the requirement that the difference value of the output voltage minus the target voltage is 0V can be satisfied only if the target level is lower than 7 according to the table 1.
In one possible implementation, the method further includes: acquiring a preset compensation level table, and looking up a table according to the compensation level table to determine a target compensation level; the preset compensation level table comprises: the compensation level and the compensation voltage value corresponding to each compensation level.
In the implementation mode, the compensation level and the compensation voltage value corresponding to each compensation level are stored in the preset compensation level table, and the target compensation level is determined in a table look-up mode more intuitively and clearly. Optionally, the preset compensation registry is stored in the compensated ac voltage regulator connection controller or in a memory. In addition, as can be seen from the structure shown in fig. 1, since the compensation voltage values are different for each compensation level according to the output voltage Uout, a preset compensation level table is stored for each output voltage Uout.
As can be seen from the foregoing compensation levels and compensation voltages in table 1, considering the complexity and cost of the circuit structure of the compensation ac voltage regulator, the number of compensation switches should not be excessive, so that the compensation unit can implement a limited number of compensation voltage adjustments according to different on-off state combinations of the plurality of compensation switches. Based on the adjustment of a limited number of compensation voltages, in the actual implementation process, the adjustment of the output voltage to approach the target voltage can be realized, but the output voltage and the target voltage cannot be guaranteed to be completely consistent, i.e. after voltage stabilization adjustment, certain errors still exist between the output voltage and the target voltage. Therefore, in the present embodiment, a first threshold value and a second threshold value are set, the first threshold value being smaller than the second threshold value. The first threshold value is smaller than or equal to the minimum compensation voltage value corresponding to the combined compensation units. If the absolute value of the difference value of the output voltage minus the target voltage is smaller than the first threshold value, the output voltage is close to the target voltage, and the output voltage is not equal to the target voltage after voltage compensation is performed based on any compensation grade, and voltage compensation adjustment is not performed at the moment.
If the absolute value is larger than or equal to the first threshold value and smaller than the second threshold value, the output voltage is smaller in deviation from the target voltage, and at the moment, the voltage overshoot is avoided by carrying out small-amplitude voltage compensation based on a slow adjustment scheme.
If the absolute value is larger than or equal to the second threshold value, the output voltage deviates from the target voltage to a larger extent, and at the moment, the rapid adjustment is realized by performing large-amplitude voltage compensation based on the rapid adjustment scheme.
The first threshold value and the second threshold value are set based on the output voltage, and the larger the output voltage is, the larger the first threshold value and the second threshold value are.
In other possible implementations, the compensation level is calculated by means of a formula, as opposed to querying a preset compensation level table. The output voltage, the target voltage and the current level are input into a formula, and the formula outputs the target compensation level. And integrating the compensation grade relations corresponding to different output voltages in a formula form, and reducing the compensation grade and the storage capacity of the compensation voltage relation.
S204, voltage compensation control is performed on the compensation type alternating current voltage stabilizer based on the target compensation level.
Referring to the description of fig. 1 and table 1, different compensation levels correspond to different compensation voltages, and correspondingly correspond to different on-off state combinations of the compensation switches, voltage compensation control is performed on the compensation ac voltage regulator based on the target compensation level, that is, the on-off state of the compensation switch is adjusted according to the target compensation level.
In this embodiment, the actual output voltage of the compensation ac voltage stabilizer is obtained to perform compensation adjustment on the ac voltage stabilizer, so as to avoid overshoot or mis-adjustment occurring when compensation adjustment is performed based on mains input, and reduce the number of trial and error times of compensation adjustment. In addition, after the output voltage of the compensation type alternating current voltage stabilizer is obtained, the absolute value of the difference value of the output voltage minus the target voltage is determined, and a fast compensation scheme or a slow compensation scheme is selected according to the relation among the absolute value, the first threshold value and the second threshold value so as to adapt to the voltage stability adjustment requirement when the difference between the output voltage and the target voltage is smaller, and in addition, the compensation type alternating current voltage stabilizer also adapts to the fast adjustment requirement when the difference between the output voltage and the target voltage is larger, so that the adjustment efficiency is improved.
In one possible implementation, determining the target compensation level based on the current compensation level and the slow compensation scheme includes:
if the difference value is greater than zero and the current level is not the lowest level, determining the compensation level of the lower level than the current compensation level as the target compensation level; if the difference value is greater than zero and the current level is the lowest level, determining the lowest level as the target compensation level;
if the difference value is smaller than zero and the current grade is not the highest grade, determining that the compensation grade higher than the current compensation grade is the target compensation grade; if the difference value is greater than zero and the current grade is the highest grade, determining that the highest grade is the target compensation grade; the compensation voltage values corresponding to the compensation grades from low to high are from small to large, and the compensation voltage values comprise negative voltage values, zero values and positive voltage values.
Specifically, on the basis that the absolute value is greater than or equal to the first threshold value and less than the second threshold value, if the difference value is greater than or equal to zero, that is, the output voltage is greater than the target voltage, the compensation level needs to be reduced; if the difference is less than or equal to zero, i.e. the output voltage is greater than the target voltage, the compensation level needs to be increased.
When the absolute value is detected to be larger than or equal to the first threshold value and smaller than the second threshold value at different moments, different on-off state combination modes of a plurality of compensation switches in a compensation unit of the compensation type alternating current voltage stabilizer are not fixed. Therefore, there are cases where the current compensation level is already at the lowest level when the compensation level needs to be lowered, and the current compensation level is already at the highest level when the compensation level needs to be raised, and accordingly, the current compensation level is maintained unchanged. In addition, the up-stage or down-stage processing is performed on the current compensation level in a single-stage adjustment mode.
The absolute value is larger than or equal to the first threshold value and smaller than the second threshold value, namely the degree of deviation of the output voltage from the target voltage is smaller, so that the compensation voltage is adjusted in a step-by-step reduction mode, and overshoot can be avoided.
In one embodiment, the first threshold is 4V, the second threshold is 10V, the preset compensation level table is illustrated in table 1, and if the current compensation level is 8 levels and the difference is 3V, no compensation level adjustment is performed; if the current compensation level is 8 levels and the difference value is 4.2V, the current compensation level is reduced to 7 levels to just meet the difference value of 0V; if the current compensation level is 8, the difference value is 9V, and the current compensation level is reduced to 7; if the current compensation level is 7, the difference is-9V, and the current compensation level is 8.
It can be seen that if the current compensation level is 8, the difference is 9V, there is still the possibility that the difference is greater than zero when the level is dropped to 7, and that overshoot occurs when the level is dropped to 6, i.e. the difference is from greater than zero to less than zero. In addition, according to the foregoing embodiments, the compensation level and the compensation voltage are different according to the output voltage value. Therefore, in the step-by-step degradation mode, when the output voltage is reduced to 7 levels, the corresponding compensation level and the compensation voltage are changed, if the difference value is still larger than zero, the compensation level can be further reduced, and the step-by-step degradation process can also reduce voltage fluctuation.
In the embodiment, when the difference between the output voltage and the target voltage is smaller, the circuit voltage fluctuation in the process of compensating voltage adjustment is reduced based on a slow compensation scheme, so that the voltage stability adjustment requirement is met.
In one possible implementation, determining the target compensation level based on the current compensation level and the fast compensation scheme includes:
if the difference value is greater than zero and the current level is not the lowest level, determining a target compensation level according to the difference value and the current compensation level; if the difference value is greater than zero and the current level is the lowest level, determining the lowest level as the target compensation level;
If the difference value is smaller than zero and the current grade is not the highest grade, determining a target compensation grade according to the difference value and the current compensation grade; if the difference value is greater than zero and the current grade is the highest grade, determining that the highest grade is the target compensation grade; the compensation voltage values corresponding to the compensation grades from low to high are from small to large, and the compensation voltage values comprise negative voltage values, zero values and positive voltage values.
Specifically, in the same way as in the foregoing embodiment, on the basis that the absolute value is greater than or equal to the second threshold, if the difference is greater than or equal to zero, that is, the output voltage is greater than the target voltage, the compensation level needs to be reduced; if the difference is less than or equal to zero, i.e. the output voltage is greater than the target voltage, the compensation level needs to be increased. There are cases where the current compensation level is already at the lowest level when the compensation level needs to be lowered, and where the current compensation level is already at the highest level when the compensation level needs to be raised, and accordingly, the current compensation level is maintained unchanged.
Unlike the foregoing embodiments, in this embodiment, the output voltage deviates from the target voltage to a greater extent, and the output voltage needs to be greatly adjusted, and the adjustment time is prolonged by adopting gradual reduction, so that a rapid compensation scheme is adopted to implement multistage upgrading or degradation.
In one embodiment, taking the first threshold value of 4V, the second threshold value of 10V and the preset compensation level table as shown in table 1 as an example, if the current compensation level is 8 levels and the difference value is 11V, the two levels are directly reduced to 6 levels; if the current compensation level is 6 levels and the difference value is-15V, the current compensation level is directly increased by 3 levels to 9 levels.
In the embodiment, when the difference between the output voltage and the target voltage is large, single multi-stage lifting is realized based on a rapid compensation scheme, and the voltage compensation adjustment efficiency is improved.
In a specific implementation process, when a single multi-stage lifting is performed on the compensation level based on the foregoing embodiment, a voltage is greatly fluctuated.
In one possible implementation, determining the target compensation level based on the difference and the current compensation level includes:
determining candidate target compensation levels according to the difference value and the current compensation level;
when the grade span between the candidate target compensation grade and the current compensation grade is smaller than or equal to the set grade number, determining the candidate target compensation grade as the target grade;
when the grade span between the candidate target compensation grade and the current compensation grade is larger than the set grade number, determining the target compensation grade according to the current compensation grade and the set grade number; if the difference value is greater than zero, the candidate target compensation level priority is lower than the target compensation level; and if the difference value is smaller than zero, the candidate target compensation level is higher than the target compensation level in priority.
The set level is determined according to the output voltage, the compensation level and the compensation voltage value corresponding to each compensation level. The number of stages, i.e., the maximum adjustment amount for a single upgrade or reduction, is set.
In one embodiment, the preset compensation level table is illustrated in table 1, where the number of steps is 3, the first threshold is 4V, the second threshold is 10V. If the current compensation level is 8 levels and the difference value is 11V, determining that the candidate target compensation level is 6 levels according to table 1, and if the span between the candidate target compensation level and the current compensation level is 8 levels is less than 3 levels, directly continuously reducing the two levels to 6 levels; if the current compensation level is 6 levels and the difference value is-15V, directly rising the current compensation level to 3 levels to 9 levels; if the current compensation level is 6 levels and the difference is-35V, the candidate target compensation level is determined to be 10 levels, the span between the candidate target compensation level and the current compensation level 6 level is 4 levels, the current compensation level exceeds the set level 3 levels, the current compensation level is directly increased by 3 levels to 9 levels, and after the adjustment according to the target compensation level is completed, the steps S201 to S204 in the previous embodiment are repeated based on the latest acquired output voltage.
In this embodiment, the change span of the single compensation level is limited based on the set level number, so that the single compensation voltage adjustment amount is limited, and the circuit voltage fluctuation is prevented from being too large, so that the influence of the voltage fluctuation on the load device is prevented.
In one possible implementation, after performing voltage compensation control on the compensated ac voltage regulator based on the target compensation level, the method further includes:
determining a sampling time interval of the output voltage according to the absolute value; wherein, the smaller the absolute value, the smaller the corresponding acquisition time interval.
In this embodiment, when the absolute value is large, the voltage difference before and after the voltage compensation is large, the voltage in the circuit is large, and the time for stable recovery is long, so that the sampling time interval of the output voltage is increased, and the accuracy of the sampling result can be ensured.
In addition, when the SCR driver is turned off, a zero crossing of current is also required to turn the SCR off completely. Thus, when the voltage compensation level adjustment is performed twice before and after, the voltage compensation level adjustment time interval is at least an integer multiple of the grid voltage period.
Fig. 3 is a flowchart of an implementation of a method for controlling a compensated ac voltage regulator according to an embodiment of the present application, as shown in fig. 3, the method includes the following steps:
determining a difference of the output voltage minus the target voltage;
judging whether the absolute value is larger than or equal to a second threshold value;
and under the condition that the absolute value is greater than or equal to a second threshold value, executing the quick compensation control, otherwise, judging whether the absolute value is greater than or equal to a first threshold value, if so, executing the quick compensation control, otherwise, returning to the step of determining the difference value of the output voltage minus the target voltage.
Wherein, carry out the quick compensation control, specifically include:
judging whether the difference is larger than zero;
judging whether the current voltage compensation level is greater than the lowest level or not under the condition that the difference value is greater than zero, gradually reducing the level according to the set level when the current voltage compensation level is greater than the lowest level, or directly lifting the current voltage compensation level to the target compensation level, wherein the level limit is the lowest level when the current voltage compensation level is the lowest level;
and under the condition that the difference value is smaller than zero, judging whether the current voltage compensation level is smaller than the highest level, gradually increasing the level according to the set level when the current voltage compensation level is smaller than the highest level, or directly increasing the current voltage compensation level to the target compensation level, and when the current voltage compensation level is the highest level, the level limit is the highest level.
Wherein, carry out the compensation control of slow speed, specifically include:
judging whether the difference is larger than zero;
judging whether the current voltage compensation level is greater than the lowest level or not under the condition that the difference value is greater than zero, reducing one level when the current voltage compensation level is greater than the lowest level, and limiting the level to be the lowest level when the current voltage compensation level is the lowest level;
and under the condition that the difference value is smaller than zero, judging whether the current voltage compensation level is smaller than the highest level, if so, lifting one level, and if so, limiting the level to the highest level.
It should be understood that the sequence number of each step in the foregoing embodiment does not mean that the execution sequence of each process should be determined by the function and the internal logic of each process, and should not limit the implementation process of the embodiment of the present application in any way.
