Load side mother of electric transformer In the case where the effective power value is small (effective power, between the first reference value and the second reference value), the input of the capacitor of the large electric valley is prohibited, and the value of the capacitor is small. The closing of the capacitor is used to adjust the power factor. This is when the effective power value is small, and the control is performed according to the condition that the invalid power value is smaller.

(Effect of the Invention) According to the present invention, when the effective power value is equal to or greater than the first reference value, or the j-effect power value is less than the first reference value and is equal to or greater than the second reference value, and the power value is the third threshold When the value is equal to or greater than the value, the capacitor corresponding to the value of the invalid power value is subjected to the opening and closing control, and when the effective power value is a reference value and is equal to or greater than the second reference value, and the invalid power value is unintelligible, the system is limited to The capacitance corresponding to the ineffective power value to the small capacitance value = the opening and closing control 'so that', even if the effective power value becomes small and the power is ineffective, it becomes possible to achieve the value regardless of the effective power value and the invalid force value. The size of the device can adjust the effect of the most appropriate power factor. [Embodiment] Hereinafter, the power factor adjusting device of the present invention is applied to a power receiving system and a system according to the drawings for indicating the embodiment. The case where the opening and closing of a plurality of capacitors for improving the power factor connected to the load side busbar of the transformer for power transformation is controlled will be described as an example. Embodiment 1 317638 8 1275921 Fig. 1 is a block diagram showing the configuration of a power receiving system using a power factor adjusting device 1 having an embodiment of the present invention. In Fig. 1, a current transformer 4 is provided on the load side bus 3 of the transformer 2 for measuring the line current value of each phase of the load side bus 3. Further, (4) the carrier side busbar 3 is connected to the detector transformer 5 for measuring the electric enthalpy value of each phase of the load side bus bar 3. The measured line current value and voltage value of each phase are transmitted to the power factor adjustment device! The power calculation unit 6' of the power calculation means calculates the effective power value P and the invalid power value Q. The effective power value p is transmitted to the control unit selection circuit 7 as a control signal generation means, and the non-f power value Q is transmitted to the control unit selection circuit 7 as the first master control unit 8 and The sub-control unit as the second control means selects the circuit 7 from the control unit 7 to the third reference value of the invalid power order and the invalid meter, and each of them is used as the first control 7\-threshold value. And the second determination as the second control signal is transmitted to the main control unit 8 and the sub-control unit 9. The main control unit 8 turns off the first capacitor based on the invalid power Q transmitted from the power calculation unit 6 and the control unit circuit 7, and turns off the first capacitor (Cm) 10 first opening and closing. Two: For the b signal of the first opening and closing signal of (4), pass all the w = closed hand 1 and the main opening and closing part 11. In the first embodiment, the electric valley value of the power transmission is set to be equal. The sub-control unit 9 is the root path 7 偻 = 6 = the transmitted invalid power value Q and the control unit selects the electric μ sub-electrical device determination value 乂 b, which is used to turn off the second capacitor. The a signal of the second opening and closing signal and the a signal of the first opening and closing signal opened by 317638 9 1275921 are transmitted to the sub-opening and closing portion 13 of the segment. In the embodiment, the capacitance value of the second opening and closing hand is equal, and the electric power of the sub-capacitor 12 is set to be higher! The main power is 1 (1), and the main capacitor 1 corresponding to the input 3 signal is turned on by the main capacitor 1 of the b signal. Sub-I: A sub-capacitor corresponding to the input eight signal; the sub-capacitor for the a signal is cryed 12 and η ^ is turned off, and the corresponding system is via the transformer u; the power supply: two ': the carrier side bus ^ And _ in the negotiation =, = pressure 3 electricity = supply to the load 15. Another one. 14' Power Generation Next, the operation of the power receiving and receiving system shown in Fig. 1 will be described. The converter 4 and the detector of the load side bus bar 3 of the presser 2 are each used to measure the line current of each phase and the voltage of each phase, and transmit the line value 牦 and the voltage value 5a to the power calculation unit 6 . Fig. 2 shows the configuration of the electric power management unit 6. In the second item, the voltage phase shifter '61 is only in time: the phase delay of the voltage; τ/2. The invalid power unit 62 calculates the invalid power, and the effective power unit 63 calculates the effective power. The multiplication blocks 64 and 65 multiply the inputs. In addition, the addition blocks 66 and 67 add the outputs of the multiplication blocks 64 and 65, respectively. ^ ^ Next, the operation of the power calculation unit 6 will be described. The voltage value 5a transmitted to each phase of the power calculation unit 6 is transmitted to the voltage phase shifter 61, and only the phase delay is 7 Γ /2. The voltage values of the phases after the delay phase are transmitted to the multiplication block 64 of the invalid power unit 62. The multiplication block 64 is the delay phase: 317638 10 1275921 The voltage value of each phase is multiplied by the line current value 4a of each phase. The result of the multiplication by the multiplication block 64 is transmitted to the addition block 66, and after the addition and subtraction, the effective value of the three-phase total invalid power, that is, the invalid power value Q is output. On the other hand, the voltage value 5a transmitted to each phase of the power calculation unit 6 is directly transmitted to the multiplication block 65 of the effective power unit 63 without passing through the voltage phase shifter 61. The multiplication block 65 multiplies the voltage value of each phase and the line current value 各 of each phase. The result of the multiplication by the multiplication block 65 is transmitted to the addition block 67, and after the addition is performed, the effective value of the three-phase total effective power, that is, the effective power value p is output. The effective power value p and the invalid power value Q which are rotated by the power calculation unit 6 are transmitted to the control unit selection circuit 7 as shown in the figure of FIG. The third figure shows the configuration of the control unit selection circuit 7. In Fig. 3, the light load check soil 1 of the effective power is set to a predetermined value and transmitted to the comparator 74. The first part: 2 sets the second reference value τ 2 of the light load detection of the effective power to a predetermined value, and transmits it to the comparator 75. Third, the third reference of the light load detection of ',,, and invalid power, the ^3 value determining unit 73 is transmitted to the comparator 76. Comparator 74 to 2 outputs logic signals! Or G. The logic circuit 7 7 compares the input persons, and according to the predetermined logic formula, the logic signal id: 8 is based on the input 'fixed value 7a and the second determined value 7b ^ ^ as the first judgment j疋 value 7b Take out. Next, the control unit selection circuit will be described with respect to the first reference value T1 and the effective power value (four). The comparator 74 performs a comparison, and determines that the large power 317638 11 1275921 is the first reference value τ money 1 at the effective power value P, and the logical signal 0 is turned on when the effective power value ρ does not reach the first reference value. The comparator 75 compares the second base and the logical line, and determines the magnitude of the effective power value. When the effective power value is increased, the output logic signal 1 outputs a logic signal 在 when the effective power value is Τ2 value Τ2. The comparator 76 compares the first reference with the invalid power value Q, and determines that the magnitude h the second reference value is 3 Q or more than the third reference value T3, and the output = the power value Q does not reach the third reference value. When the thermal power system is Q at the output of the ratio h 74 and the comparison = circuit is 1' and the turn-off signal of the round-trip signal number of the comparator 76 is 1, the logic signal 7 is rotated. In other conditions, the output value is a value of 7a. The logic circuit 78, when the output signal of the output 俨轳Λ 1 ° ° 74 of the comparator 75 is 0 and is in the middle of the wheel of the comparator 76, The logic signal 1 is outputted as the second determination value; the round-out condition is (4) the output logic signal is outputted as the second determination value 7b, and the main control unit 8 is in the control unit. The selection circuit 7 transmits the determination value 7a as the man-hour, based on the value of the invalid power value Q from the power shipment, and the power capacitance value of the known N mains and 10 in advance, so as to achieve the target power. The factor above the Guzan rate is 1 or the N-side busbars connected to the Echizen power due to the 'Xin' and the 3rd-side busbars are connected to the main opening and closing section η. On the other hand, the other is the main 317638 12 1275921 The device 1〇's these main capacitors are turned on and output to ]°卩11. Further, when the first determination value 7a is 〇, for all the main power states 10, the b signal is output to The main opening and closing unit 丨丨, and 7 all the main capacitors 10. The sub-control unit 9 is in the control unit selection circuit. When the transmitted second determination value 71 > is 1, the value of the invalid power value Q transmitted from the power calculation unit 65 and the power capacitance value of the known tantalum capacitor 12 are previously made to be the target. The power factor is the same as the power factor, and the load side bus 3 is connected, and the meso of the sub-capacitor 12 is turned off, and the second sub-opening and closing section 13 is output. In the other aspect, the other (M_m) sub-capacitors 2 are outputting the & signals of the sub-capacitors to the sub-opening and closing section 13. Further, when the second determination value is 〇, for all the μ 4 capacitors 12, the a signal is output to the sub-opening and closing portion 13, and the sub-capacitor 12 is provided. The main opening and closing portion 11 of the hall is electrically connected to the switch provided in the main capacitor_10 corresponding to the input 3 signal. It is desirable to turn off the white & main capacitors and make the switches provided in the main capacitor corresponding to the input 1) signal non-conductive, thereby opening the desired (Ν_η) main capacitors 10. Further, The sub-opening and closing section 13 will correspond to the The switch provided in the sub-capacitor 12 of the turn-on Α signal is turned on, whereby the desired m sub-capacitors 12 are turned off, and the switch provided in the sub-capacitor 12 corresponding to the injected a signal becomes Non-conducting, thereby opening the desired (Mm) sub-capacitors 12. In the first embodiment, the above-described first to third references are set by using the measurement of the prior 317638 13 1275921 by a power meter or the like. The value setting unit sets the first to third reference values TUT3 to be set, for example, each of which measures the effective power value Pd in a state in which the home power generation system is operated during the day, and the home power generation system 16 at night.

In addition, the effective power value ph for measuring the holiday is set to 2, and the body is set to Ph < T2 < Pn. In addition, T3' is specifically set by measuring the reactive power Qd' in the state in which the home power generation system 16 is operating during the daytime and the invalid power value Qn' in the state in which the home power generation system 16 is stopped at night. In the power factor adjusting device ι configured as described above, the effective power value ρ and the invalid power value Q become active in the state in which the home power generation system 16 is stopped when the white space is flat. . + i v 7 夂 夂 乂 。 。. That is, the effective power value P becomes T1 = P ', so that the output of the logic circuit 77 is 1 and the output of the logic circuit 77 is 1 and the output of the logic circuit 77 is 1%. Become a beggar. In this case, in the main control unit 8, the main control unit 8 corresponds to the invalid power value, and the value is y. The main opening/closing unit is used to perform the opening and closing control of the main rake Ί H H H 谷 TO 1 () Therefore, it can avoid becoming a post-ice power factor. In addition, during the daytime on weekdays, 佬λα 八τ will operate from the power generation system16, and if you consider the effective power supplied by your own #雷系^^ 豕七包糸 system16, the effective power value Ρ becomes more than +, .φ ^ ^ ^ and the invalid power value Q becomes larger due to the characteristics of the generator. That is, the relationship between P for the effective power value P and the invalid power value Q, T2$P < T1 and T3 < 0 == Q is established, 14 317638 1275921 of the comparator 74 is 0 and the wheel of the comparator 75 becomes i, Therefore, the logic circuit ^ is 1' and the output of the comparator 76 is ☆ The output of the L L# is 1 and the round of the logic circuit 78 is 0.

In this case, as described above, the main control unit 8 and the sub- 15 317638 k 1275921 = part 9 output b signals and a wide to the main opening and closing unit 11 and the sub-opening and closing unit u, so that all the main capacitors 1 and the sub-capacitors are provided. The i2 is hit and sweated, that is, since the Asian capacitors are not turned off, it is possible to avoid a situation in which the power factor is greatly advanced. As described above, according to the embodiment ι, regardless of the magnitude of the effective power value p = large j and the ineffective power value Q, the formation of the hysteresis power factor can be avoided, so that the optimum power factor can be adjusted. In the above description, the power capacitance values of the main capacitor 10 and the sub-capacitor cry 12 are all equal, but it is not necessary to make the electric power valleys equal. That is, the electric power valleys of the main capacitor 1 () and the sub-capacitor U may be different from each other. Further, in the above description, the total value of the electric valleys of the electric field port 12 is smaller than the capacitance value of the one main capacitor 10, but the latter need not be large. In addition, in the above description, the target power factor is described as 1, but the target power factor does not have to be as long as the value is close to 1 'the power factor can be the lagging power factor or the leading power factor. . In the second embodiment, the third reference value T3 is determined based on the "invalid power value Q measured in advance" by the t-force meter. In contrast, in the second embodiment, the second embodiment is not invalid. The power value is measured, but the U-three reference value T3U is set according to the benefit power value Q at the time of the input of the reference signal ^4, and the power factor adjusting device of the second embodiment is controlled. The configuration of the system is the same as that of the embodiment of the figure i 317638 16 1275921 2:1. Therefore, the description is omitted. In the second embodiment, the control unit selection circuit 7G is used instead of the control unit of the first figure. The fourth embodiment of the circuit shows the control unit selection circuit % of the second embodiment, which corresponds to the third embodiment of the first embodiment. The same reference numerals are given to the third embodiment, and the description is omitted. In the figure, = is the reference value setting signal output means, the third reference value setting signal part (4) t outputs the logic signal 1 or G. As the maximum and minimum invalid power memory == the maximum and minimum invalid power memory (fourth), based on Power f nose 6 The effective power value P and the invalid power value Q, the second (four) value τι and the second reference value T2, determine the large invalid power Qmax and the minimum invalid power coffee that should be memorized ▲ as the maximum invalid power memory means The maximum invalid power memory unit 〇3 stores the maximum power-efficient power Qmax, and the minimum invalid power memory unit 704, which is the minimum invalid power memory means, stores the minimum invalid power Qmin as a reference value calculation means. The third reference value calculation unit 7〇5 calculates the third reference value Τ3 based on the large invalid power Qmax and the minimum invalid power gamma. The operation of the power receiving and receiving system according to the second embodiment will be described. In the second embodiment, the operation of the second reference value Τ3 is different from that of the first embodiment in the second embodiment. The third and second setting signal units 7〇1 output a logic signal in the normal state. 0, but when the third reference value Τ3, the output logic signal 1 is used as the reference value setting signal. When the logic signal is output, the logic "AND" in the logic circuit 771 is 317638 17 1275921 Circuit 772 and logic circuit 781 are logical signals. Further, when the effective electric power value P is less than the first reference value T1 and is on the second reference, that is, when the relationship of W < T1 is established, D: 3. In this case, the rounding of the comparator 74 becomes a logical signal 〇. :: By the main control unit 8 and the sub-control unit 9, the main capacitors 1 and 12 are all controlled to be (four). Therefore, setting the third reference value can eliminate the effects of all capacitors. The maximum and minimum invalid power memory control unit 〇2 is set to the second, and the teacher outputs the ς signal 1 from the third reference value setting signal unit 7〇, and the effective power value ρ is In the case of T2$p<Tl, the action is performed. Thereafter, if the invalid power value (3 is greater than the maximum invalid power Qmax stored in the maximum inactive power I memory unit 703, the value of the invalid power value Q is used as the new maximum invalid power Qmax, and the maximum is invalid. The power storage unit 703. On the other hand, if the invalid power value Q is smaller than the minimum invalid power gamma stored in the minimum invalid power storage unit 704, the value of the invalid power value Q is used as the minimum invalid power Qmh. And stored in the minimum invalid power memory unit 〇4. The third reference value calculation unit is the largest non-S power memory 胄7〇3 jin memory of the maximum invalid power Q m ax ' and the minimum invalid power memory unit 7 〇 4 The intermediate value Qave=( Qmax+Qmin ) Q between the values of the stored minimum invalid power Qmin is calculated, and Qave is used as the third reference value T3, and is transmitted to the third setting = 73. When the third reference is ended The shirt of the value Τ3 stops the output of the reference value setting signal, and ends the setting operation. That is, the logic signal rotated from the third reference value setting signal unit 701 is changed from 1 to 0. 317638 18 1275921 by Above you The third reference value 'there is no need to measure the invalid power value Q in advance. The value setting signal unit adds 2 to the above-described operation. 'When the logic signal 1 is output from the third reference p<T2, θ, the effective power value 卩 is , T i ^ ~ only 'Dare to be the smallest invalid power memory control unit 702 does not operate. That is, in the running state or in the daytime, the home power generation system 16 stops off and enters, in the same When the value of the three reference values T3 is not complete, the 'maximum minimum invalid power memory control unit and the rightward binding operation' are operated only under the condition that the value of the third reference value Τ3 is associated with the control. In the third embodiment, the reference value setting signal is used, and the month in which the word invalid power value Q is measured to 'set the third reference value' is used. The power capacitance value of the sub-electric coffee is set to the third reference value. The configuration of the power-receiving system 2 of the power factor adjusting device i in which the B-type 3 is applied is the same as that in the first embodiment of the first embodiment. Therefore, the description is omitted. In Embodiment 3 The control unit selection circuit is employed in place of the control unit selection circuit 7 of the first drawing. Fig. 5 is a block diagram showing the control unit selection circuit of the embodiment and the third embodiment, which corresponds to the third embodiment of the embodiment i and The fourth part of the second embodiment is the same as that of the third or fourth embodiment, and the same reference numeral is attached, and the description is omitted. In the fifth figure, the main memory of the first memory means var. The value setting unit 7001 stores the invalid power value of the power capacitance value of the main capacitor in advance, and the second capacitor var value setting unit 7002 of the memory hand 317638 19 1275921 is used as the sub capacitor in advance. The power var value of the power capacitance value of 12 is memorized. The third reference value calculation unit 705, which is the reference value calculation means, calculates the main capacitor var value and the sub-capacitor var value transmitted from the main capacitor var value setting unit 7001 and the sub-capacitor var value setting unit 7002. The third reference value T3 is calculated. Next, the operation of the power receiving and receiving system according to the third embodiment will be described. The general operation is the same as that of the first embodiment, and thus the description thereof is omitted. In the third embodiment, the main capacitor var value setting unit 7001 transmits the power capacitance value Q1 of one main capacitor 10 to the third reference value calculation unit 705. On the other hand, the sub-capacitor var value setting unit 7002 transmits the sum Q2 of the power capacitance values of all the sub-capacitors 12 to the third reference value calculation unit 705. The third reference value calculation unit 705 transmits (Q1+Q2)/2 as the third reference value T3 based on Q1 and Q2, and transmits it to the third reference value setting unit 73. According to the third embodiment, as in the third embodiment, the third reference value T3 can be set without measuring the invalid power value Q in advance. (Embodiment 4) In the first embodiment, the main capacitor 10 or the sub-capacitor 12 is selectively opened and closed in accordance with the ineffective power value Q, thereby controlling the capacitance value of the capacitor, thereby controlling not to Become a lagging power factor. On the other hand, in the fourth embodiment, it is allowed to become a hysteresis power factor, and control for setting the power factor to the value closest to 1 is controlled so as not to become an extreme leading power factor. In the fourth embodiment, the first main control unit 8 1 and the main control unit 8 of the ++1 are applied to the system 20 317638 1275921.

Specifically, the second main control unit 82 replaces the first main control in the case where the relationship between the W<T1 and the Lang Q in which the own power generation system 16 is operated during the daytime is established and the hysteresis power factor is allowed. The unit 81 operates. In other words, the second main control unit 82 is controlled by selectively opening and closing the main capacitor 1〇 by the main opening/closing unit Π', while allowing the power factor to be close to 1 while allowing the hysteresis power factor to be achieved. Control, while controlling is not going to be an extreme lead power factor. In the above case, the sub-control unit 9 is also the same as the second main control unit 82, and 317638 22 1275921 performs control for making the power factor the most, and the value of ^ 〆 k is close to 1. Further, the subsequent operations are inconsistent with the first embodiment, and thus the description will be omitted. As explained above, according to the Governor
