Below in conjunction with accompanying drawing, the present invention is described in further detail.
This specific embodiment is only explanation of the invention; it is not limitation of the present invention; those skilled in the art are reading after this description and can make to the present embodiment the amendment that there is no creative contribution as required, but as long as within the scope of claim of the present invention, are all subject to the protection of Patent Law.
When capacitance compensation, electric capacity and load are connected in parallel, in the time that load increases, because power supply exists internal resistance, electric power output voltage will decline, so need to detect by the parameter such as voltage, electric current to both ends of power, so that the electric power thus supplied of monitoring power supply unit regulates distribution system according to specific circumstances. Parallel-connected Capacitor compensation is a kind of voltage regulating mode comparatively traditional in current distribution system, by carrying out load or burden without work compensation in load side, reduce the reactive power flowing through on distribution line, but more often cause load side voltage seriously out-of-limit in load fluctuation, and operation trouble, has larger drawback. And series capacitor compensation, by seal in electric capacity in distribution line, the reactance in compensation distribution line reduces the voltage loss in distribution line impedance, and it has stronger dynamic voltage adjustment ability. Capacitances in series compensation has improved the transmission power limit of power transmission network, has comparatively significantly effect to improving static stability. But also research is very few at present in the application of series capacitor compensation in distribution system, known by researching and analysing, series capacitor compensation has good voltage dynamic adjustments performance. Can in the voltage-regulation of distribution system, play an important role.
Wherein having a kind of compensation way is the series capacitor compensation that adopts brake tube control, as shown in Figure 4, can, by after an electric capacity and inductance in parallel, obtain an equivalent reactance by the angle of flow of controlling IGCT.

Therefore,, after inductive branch is in parallel with capacitive branch, the character of the equivalent reactance of whole circuit and size all can be adjusted by controlling IGCT Trigger Angle α. When the equivalent inductive reactance value of controlling when α angle is less than the capacitor value of electric capacity, whole circuit presents perception, otherwise whole circuit presents capacitive. And by analysis, the equivalent reactance of whole circuit can calculate with formula, and its formula is: Xeq=1/(ωC)-A/(πωC)*[2(π-α)+sin2(π-α)]+4Acos2(π-α)x*[ktan(kπ-kα)-tan(π-α)]/πωC(k2-1). Wherein, A=k2/(k2-1)，k=ω0/ω，ω0=1/（LC）1/2. Trigger Angle α and XeqRelation curve as shown in Figure 5, wherein than for just representing that whole circuit is capacitive, otherwise be perception.
Trigger Angle real-time location only, by the voltage loss of Fig. 4 distribution line is analyzed, supposes that load power factor angle is θ (> 0, perception), after building-out capacitor, line impedance is still perception, with load current ILFor with reference to phasor, can obtain voltage loss phasor diagram as shown in Figure 6. The terminal voltage steady state value U realizing by wish2bReplace UL, and the computing formula substitution triangle relation of voltage loss longitudinal component △ U and cross stream component δ U, the real-Time Compensation amount computing formula that can obtain electric capacity is as follows:
XC=[(S-L 2XL+QLU2b 2)-(S-L 2UA 2U2b 2-S-L 4R2-2S-L 2PLRU2b 2-PL 2U2b 4)1/2/S-L 2]; Wherein, PL、QL、SLBe respectively active power, reactive power and the apparent energy of load. XCX in substitution formulaeqCan calculate the instantaneous value of Trigger Angle α. The α instantaneous value calculating is controlled IGCT, can be made terminal voltage under variable load, still be stabilized in terminal voltage steady state value U2bOn.
