The embodiment of the application provides a reactive compensation control method, referring to fig. 1, comprising the following steps: s100, S200, S300.

S100: and acquiring circuit parameters of the current three-phase circuit in real time, and calculating capacitance switching parameters of the current three-phase circuit according to the circuit parameters.

In the embodiment provided by the application, the circuit parameters in the current three-phase circuit system are obtained in real time through the data detection module, wherein the circuit parameters comprise voltage, current and temperature; the temperature is the temperature of the capacitor to be switched in the current three-phase circuit system, and the current and the voltage in the three-phase circuit system. Optionally, the circuit parameters include: the voltage and current of each phase, the temperature of each capacitor and the accumulated running time of the put-into-operation are calculated, and then the reactive power, the active power, the power factor and the harmonic wave of each phase are calculated. The temperature of the capacitor to be switched is one of the bases for determining the capacitor to be switched, and if the capacitor with higher temperature is put into the current three-phase circuit, the service life of the corresponding capacitor is reduced. Therefore, the service life of the capacitor is prolonged by reducing the service frequency of the capacitor with high temperature.

Optionally the circuit parameters comprise voltage, current and temperature of each phase in the current three-phase circuit; the calculating the capacitor switching parameter of the current three-phase circuit according to the circuit parameter comprises the following steps:

Calculating the power factor, three-phase imbalance and harmonic waves of each phase of the current three-phase circuit by acquiring the capacitor switching parameters acquired by the data detection module in real time; the power factor is used as a basis for whether to throw in or cut off the capacitor, wherein the power factor needs to be compared with a preset power factor throw-in threshold and/or a preset power factor throw-in threshold, and the preset power factor throw-in threshold can be considered to be set according to different application scenes. When the whole circuit system is connected with the server, the server can automatically calculate according to the detected three-phase circuit parameters and the detected three-phase circuit application scene, and a preset power factor input threshold value is determined. The three-phase imbalance is used to determine whether to use a co-compensation or sub-compensation strategy to put capacitors into the current three-phase circuit. The three-phase unbalance calculation process comprises the following steps:

collecting and obtaining three-phase current I _a 、I _b 、I _c Calculating to obtain three-phase average current I _av Three-phase unbalance = [ (MAX (I) _a 、I _b 、I _c )-I _av )/I _av ]X 100%. The harmonic wave is used for the reactive compensation controller to analyze the influence of the harmonic wave on the operation and the use of the capacitor, so that the possible situation of the capacitor can be mastered in time, and the capacitor can be reacted rapidly.

S200: and determining to switch the capacitor to the current three-phase circuit according to the capacitance switching parameter.

The capacitor switching parameters calculated on the basis of the step S100 are that the power factor is compared with a preset power factor input threshold and a preset power factor input cutting threshold in the subsequent steps, and if the power factor is determined to be smaller than the preset power factor input threshold or the power factor is determined to be larger than the preset power factor cutting threshold, the capacitor is determined to be switched on or off for the current three-phase circuit, so that a capacitor supplementing strategy for the three-phase circuit system is further determined, wherein the capacitor supplementing strategy can be divided into co-supplementing and sub-supplementing. Different capacitor supplementing strategies are adopted according to different conditions, and capacitors are supplemented in a targeted manner so as to meet the requirements of power factors.

S300: and determining a target switching capacitor according to the running time, the capacitance temperature and the switching times of a plurality of capacitors to be switched in the current three-phase circuit, and controlling the target switching capacitor to be switched in the current three-phase circuit.

After determining to switch the capacitor to the current three-phase circuit, the service life of the capacitor is prolonged in order to reduce the use frequency of the capacitor. Comparing the running time, the capacitor temperature and the switching times of a plurality of capacitors to be switched which are connected and powered off in the current three-phase circuit, taking the capacitor with the shortest running time, the lowest capacitor temperature and the lowest switching times as a target switching capacitor, and further reducing the use frequency of other capacitors, namely the use frequency of the capacitor with higher corresponding numerical values of any one of the running time, the capacitor temperature and the switching times, so as to prolong the service life of the other capacitors. The capacitor to be switched is connected with a control module in the current three-phase circuit in advance, a switching driving module is arranged between the control module and the capacitor to be switched and is connected with the capacitor to be switched, and the switching driving module can be a switching driving switch for disconnecting or connecting the circuit between the control module and the capacitor to be switched, so that switching of the capacitor is realized.

As can be seen from the foregoing step S200, the power factor is compared with the preset power factor input threshold value, and the current three-phase circuit input capacitor is determined. In yet another embodiment, comparing the power factor with a preset power factor input threshold, and determining whether the power factor is less than the preset power factor input threshold; and when the power factor is smaller than the preset power factor input threshold, indicating that the capacitor is needed to be input to the current three-phase circuit. In order to switch the capacitor in a targeted manner, excessive input of the capacitor is avoided, the use frequency of the capacitor is increased, the three-phase unbalance degree is compared with a preset three-phase unbalance degree threshold value to determine the input strategy of the current three-phase circuit, wherein the input strategy comprises the co-compensation and the sub-compensation strategies described in the previous and later, the capacitor is supplemented in a targeted manner, the requirement of power factors is met, meanwhile, the reasonable utilization of the large-capacity capacitor and the small-capacity capacitor is improved, and the service life of the capacitor is prolonged as a whole.

If the power factor is greater than the preset power factor input threshold, the power in the current three-phase circuit system can meet the requirement, and the current three-phase circuit switching capacitor is not needed at this time, determining the target switching capacitor according to the running time of the capacitor to be switched, the capacitor temperature and the switching times, and controlling the target switching capacitor to be input into the current three-phase circuit, namely stopping the calculation process of the current three-phase circuit switching strategy, the three-phase unbalance degree and the like, so as to save the memory capacity of a controller or a remote server.

The adding of the co-compensation capacitor according to the co-compensation capacitor switching control strategy comprises the following steps:

Optionally, the preset three-phase imbalance threshold is 15%.

In combination with the foregoing, after comparing the power factor with the preset power factor input threshold, it is determined that the capacitor needs to be switched in a targeted manner after the current three-phase circuit is put into the capacitor, so as to improve the service life of the capacitor and enable the capacity of the capacitor to be matched with the required capacity. In yet another embodiment, when the three-phase imbalance is greater than or equal to the three-phase imbalance threshold, switching the co-compensation capacitance according to a co-compensation capacitance switching control strategy; the power factor is smaller than the set power factor input threshold value, and the three-phase unbalance is larger than or equal to 15%, which means that when the three-phase unbalance of the current three-phase circuit system (i.e. the power supply system) is overlarge, the common compensation capacitor is input, namely the three-phase capacitor is controlled to compensate the whole current three-phase circuit. When the three-phase unbalance is smaller than the three-phase unbalance threshold, switching the co-compensation capacitors according to a switching control strategy of the sub-compensation capacitors; the power factor is smaller than the set power factor input threshold value, and the three-phase unbalance is smaller than 15%, which means that the current three-phase unbalance of the three-phase circuit system (i.e. the power supply system) meets the standard, and the sub-compensation capacitor is input. In the process of adding the sub-compensation capacitors, determining the target phase of the switching capacitor in the current three-phase circuit, and controlling the single-phase capacitor to switch the capacitor to the target phase. The three-phase circuit comprises A, B, C three phases, and when the phase A needs to be compensated, the capacitor is switched for the phase A, and when the phase B needs to be switched for the capacitor, the capacitor is switched for the phase B, and then the single-phase capacitors are respectively and independently compensated for, so that the utilization rate of the capacitors with different capacities is improved, namely, the capacitors with small capacities are needed, and the capacitors with small capacities are put into the capacitors with small capacities.

In order to ensure that the power factor of the current three-phase circuit can meet the power supply requirement after the capacitor is put into the capacitor according to the co-compensation strategy, calculating the power factor of the current three-phase circuit after the capacitor is put into the capacitor according to the co-compensation strategy, comparing the power factor with a preset power factor input threshold, and when the power factor is smaller than the preset power factor input threshold, indicating that the power factor can not meet the power supply requirement after the capacitor is put into the capacitor, putting into the capacitor again according to the co-compensation strategy, and calculating the power factor again and putting into the threshold with the preset power factor until the power factor is larger than the preset power factor input threshold. When the power factor is larger than the set power factor input threshold, the input capacitor is indicated to be capable of meeting the current operation of the three-phase circuit system, and the control implementation process of inputting the capacitor again according to the co-compensation strategy is not performed.

In order to ensure that after the capacitor is put into operation, after the capacitor is put into operation after the co-compensation strategy is needed, whether the power factor of the current three-phase circuit can meet the power supply requirement or not is ensured. Correspondingly, after the capacitor is put into the current three-phase circuit according to the phase division and compensation strategy, calculating the power factor of the current three-phase circuit after the capacitor is put into the capacitor, comparing the power factor with a preset power factor input threshold, and after the power factor is smaller than the preset power factor input threshold, indicating that the power supply requirement cannot be met by the power supply system of the current three-phase circuit after the capacitor is supplemented, putting into the capacitor again according to the phase division and compensation strategy, and calculating the power factor again and inputting the power factor with the preset power factor input threshold until the power factor is larger than the preset power factor input threshold. When the power factor is larger than a preset power factor input threshold, the input capacitor is indicated to be capable of meeting the current operation of the three-phase circuit system, and the control implementation process of inputting the capacitor again according to the division and compensation strategy is not performed.

comparing the power factor with a preset power factor cutting threshold value, and judging whether the power factor is larger than the preset power factor cutting threshold value or not;

In combination with the step S200, the power factor is compared with a preset power factor cut-off threshold value, and the current three-phase circuit cut-off capacitor is determined. In yet another embodiment, comparing the power factor with a preset power factor cut threshold, and determining whether the power factor is greater than or equal to the preset power factor cut threshold; and when the power factor is greater than or equal to the preset power factor input threshold, indicating that the capacitor is required to be cut off for the current three-phase circuit. In order to remove the capacitor in a targeted manner, the capacitor is prevented from being removed too much, the effective utilization rate of the capacitor is reduced, the three-phase unbalance degree is compared with a preset three-phase unbalance degree threshold value to determine the input strategy of the current three-phase circuit, wherein the input strategy comprises the co-compensation and the sub-compensation strategies described in the previous and later, the capacitor is removed in a targeted manner, the requirement of power factors is met, meanwhile, the reasonable utilization of the large-capacity capacitor and the small-capacity capacitor is improved, and the service life of the capacitor is prolonged as a whole.

If the power factor is smaller than the preset power factor cutting threshold, the power in the current three-phase circuit system can meet the requirement, and the current three-phase circuit is not required to be cut off, determining the target switching capacitor according to the running time of the capacitor to be switched, the capacitor temperature and the switching times, and controlling the target switching capacitor to be switched into the current three-phase circuit, namely stopping the calculation process of the current three-phase circuit switching strategy, the three-phase unbalance degree and the like, so as to save the memory capacity of a controller or a remote server.

Optionally, the preset three-phase imbalance threshold is 15%.

In combination with the foregoing, after comparing the power factor with the preset power factor removal threshold, it is determined that the capacitor needs to be removed after the current three-phase circuit removes the capacitor, so as to be able to specifically remove the capacitor, so as to improve the service life of the capacitor, and enable the capacity of the capacitor to be matched with the required amount. In yet another embodiment, when the three-phase imbalance is greater than or equal to the three-phase imbalance threshold, switching the co-compensation capacitance according to a co-compensation capacitance switching control strategy; the power factor is smaller than the set power factor input threshold value, and the three-phase unbalance is larger than or equal to 15%, which means that when the three-phase unbalance of the current three-phase circuit system (i.e. the power supply system) is overlarge, the co-compensation capacitor is cut off, namely the capacitor of the compensation capacitor of the whole current three-phase circuit is controlled to be powered off, namely the co-compensation capacitor is cut off.
