Inventor's research finds that wind energy turbine set and transformer station can be reduced to one or more equivalence electricity as shown in Figure 2
Road, for convenience of explanation, Fig. 2 is illustrated so that two circles become as an example.As shown in Fig. 2 U0And Z0Windfarm system is accessed for transformer station
Wind-powered electricity generation end wait threshold voltage and equivalent impedance, wherein Z0=R0+jX0；U1And U2Main transformer high-pressure side in a respectively region
And low-pressure side voltage；XCFor the capacitive reactance of compensation capacitor group；ZTFor transformator equivalent impedance, ZT=RT+jXT；K becomes for transformator
Than；QCFor the capacity of compensation capacitor group compensation, y is input capacitor bank number,SLFor load power, SL=PL+
jQL, PLFor load side active power, QLFor load side reactive power；S1For high voltage side of transformer power, S1=P1+jQ1, P1To become

When head and switched capacitor group, U0And SLKeep constant.Low-pressure side voltage U can be derived2, enter line side power factorMeter
Calculate formula as follows：
In formula,R1And X1For the equivalent impedance of reduction to low-pressure side.
From it is above-mentioned it is various in it can be seen that U0、U1With U2Positive correlation.U0Increase (reduction), U1To also increase, so as to U2To become
Greatly (little), i.e. Generation Side voltage influence main transformer high side voltage, so in influence area other nodes voltage.Therefore adjust
Section U0And U1, impact can be produced on the voltage of Area Node voltage and its region transformer station interior nodes, at station, interior low-pressure side is adjusted
It is that this side voltage and station are interior idle to save idle main impact, less on high side voltage impact.And U0And U1U will all be affected2,
But U1Impact it is more direct, U0By affecting U1Eventually affect U2, its regulating effect affected very big by circuit and impedance,
In the situation of supply line head, inefficiency.
Based on tree region electrical network feature, in region, the regulation of voltage should be from the high transformer station of electric pressure toward electric pressure
Low transformer station is carried out, to reduce total adjustment cost.It is big due to fluctuating the characteristics of wind-powered electricity generation itself, due also to wind-powered electricity generation is to transformer station
Transmission line of electricity it is long, cause wind-powered electricity generation to adjust and the power of influence of transformer station weakened, cause transformer substation side pressure regulation excessively frequent, wind-powered electricity generation
Regulation efficiency it is weaker, need to be optimized the pressure regulation strategy of transformer substation side, it is more efficient and reliably realize voltage power-less
Optimal control target.Ensure reactive reserve capacity enough in region simultaneously, it is ensured that the safety of line voltage.
In the present embodiment, i.e., go out to arrange first idle by the high-voltage side bus in region main website (i.e. main transformer)
Compensation device, is exerted oneself by adjusting the idle of the first reactive power compensator, is directly realized by main transformer high pressure in the regulation region
The purpose of side bus voltage, and then complete in batches (to complete the regulation of the busbar voltage of related other nodes in region in batches
Regulation to the busbar voltage of region Nei Ge regions slave station), can solve power end (wind energy turbine set) affects on high side voltage
Little, inefficient problem.Retain the dynamic reactive tunable arrangement of wind energy turbine set simultaneously, the voltage power-less for considerably increasing system is adjusted

The part of pressure is adjusted so that area's device within the domain pressure regulation optimization, number of equipment action will greatly reduce.Additionally, in present embodiment
On the basis of existing nine-zone diagram, still using busbar voltage as vertical coordinate, but change using the power factor of bus as
Abscissa, so as to be controlled with the new nine-zone diagram based on voltage-power factor, is qualitatively carried out with the size of power factor
The adjustment of the switching or tap gear of correspondence reactive power compensator, the reactive-load compensation on the high voltage bus of region main website is filled
Put as the means for improving busbar voltage, using the reactive power compensator of mesolow side bus as the regulation side for optimizing power factor
Formula, the two key indexs are separately controlled, and carry out compartmentalization voltage and Reactive-power control, it is achieved thereby that the entirety that electrical network is always netted
Control.
