Detailed description of the invention

For the ease of understanding the present invention, below with reference to relevant drawings, the present invention is described more fully.In accompanying drawing Give the preferred embodiment of the present invention.But, the present invention can realize in many different forms, however it is not limited to herein Described embodiment.On the contrary, providing the purpose of these embodiments is to make the understanding to the disclosure more saturating Thorough comprehensively.

Unless otherwise defined, all of technology used herein and scientific terminology and the technical field belonging to the present invention The implication that technical staff is generally understood that is identical.The term used the most in the description of the invention is intended merely to describe tool The purpose of the embodiment of body, it is not intended that in limiting the present invention.Term as used herein " or/and " include one or more phase Arbitrary and all of combination of the Listed Items closed.

In one embodiment, as it is shown in figure 1, a kind of power station reactor collocation method, comprise the following steps:

Step S110: obtain the input parameter of power station reactor collocation method.

The concrete kind of the input parameter of collocation method is not unique, and the input parameter of collocation method specifically can include electrical network The connected mode of circuit, line resistance, line reactance, power station dot location, power station capacity S_W, hydropower net pricing C_W、 System power supply position, the natural law T of wet season upper one year_W, reactor mounting cost C_X1, reactor year maintenance expense C_X2, reactor list Valency C_X3Life-span T with reactor_XAt least one.The connected mode of power network line is the most unique.

Step S120: calculate the input impedance of grid-connected position, power station according to the input parameter of collocation method.Specifically, exist In one embodiment, step S120 includes step 122 and step 124.

Step 122: when in the electrical network that power station is accessed other all nodes in addition to system power supply position be set to open circuit, System power supply is set to short circuit, and when power station dot location are plus voltage source, measures power station the electricity of dot location Pressure and electric current.

Step 124: obtain resistance and the reactance of input impedance according to voltage and electric current.

Specifically, the difference of the connected mode of power network line, influence whether the input impedance of the grid-connected position of small power station.Defeated Entering impedance in the definition above circuit is: possibly together with controlled source in addition to impedance inside circuit, but without any independent current source, then Port voltage is directly proportional to port current, and this ratio is defined as the input impedance of this circuit, i.e. the equivalence resistance of circuit input end Anti-.Calculate the input impedance of the grid-connected position of small hydropower station, can be the passive of a Single port by small hydropower station place circuit equivalent Network, then the input impedance calculation of the grid-connected position of small hydropower station is: system power supply is set to short circuit, all small hydropower stations with And load bus is set to open circuit, the in addition voltage source in the grid-connected position of calculated small hydropower station, then obtain the electric current of this position, electric The ratio of pressure and electric current i.e. can get input impedance.

Step S130: calculate power station not according to the input impedance of the grid-connected position of input parameter and power station of collocation method Unit when installing reactor enters phase pressure regulation cost, particularly as follows:

$C_0=24T_X{T}_W{C}_W(1-\frac{1}{\sqrt{1+R_W/X_W}})S_W$

Wherein, T_XLife-span, T for reactor_WNatural law, C for the wet season upper one year_WFor hydropower net pricing, R_WFor input The resistance of impedance, X_WReactance, S for input impedance_WFor power station capacity.

Specifically, " unit when reactor is not installed in power station enters phase pressure regulation cost " refers to that power station is uneasy in the wet season Dress reactor, the active power entering to make mutually the grid-connected point voltage in power station not sent by small power station merely with unit is affected, so that The loss that the active energy of output is caused is reduced in power station.Leading phase operation refers to reduce exciter current of generator, makes electromotor Electromotive force reduces, and power-factor angle just becomes advanced, and generator load electric current produces magnetic assist armature-reaction, and electromotor is defeated to system Send active power, but absorbing reactive power, this running status is referred to as leading phase operation.

Step S140: set up power station according to the input parameter of collocation method and the input impedance of power station dot location Reactor configuration mathematic optimal model, solves the target function value after being optimized and reactor to mathematic optimal model Capacity optimal solution:

$\begin{array}{c}\min C_X\left(Q_X\right)=24C_W{T}_X{T}_W(S_W-\frac{\frac{R_W}{X_W}{Q}_X+\sqrt{(1+\frac{R_W^2}{X_W^2}){S_W}^2-Q_X^2}}{1+\frac{R_W^2}{X_W^2}})+C_{X1}+C_{X2}{T}_X+C_{X3}{Q}_X\\ \left(0<Q_X\&le;\frac{R_W}{X_W}{S}_W\right)\end{array}$

I.e. PR_W-QX_W=0

The active-power P that sends for Hydropower Unit leading phase operation, reactive power Q_Δ, small power station capacity S_W, reactor sends out The reactive power Q gone out_X, small hydropower station the input impedance R of dot location_W+j X_W, obtain: P again²+Q_Δ ²=S_W ², abbreviation can obtain:

$P=\frac{\frac{R_W}{X_W}{Q}_X+\sqrt{\left(1+\frac{R_W^2}{X_W^2}\right){S_W}^2-Q_X^2}}{1+\frac{R_W^2}{X_W^2}}$

When Hydropower Plant is not required to send to system or during absorbing reactive power, and Hydropower Plant now can completely be sent out meritorious Power, i.e. has P=S_W, and Hydropower Plant causes the active power reducing output to be Δ P=S because of leading phase operation_W-P, knot Box-like (1) has:

$\mathrm{\&Delta;}P=S_W-\frac{\frac{R_W}{X_W}{Q}_X+\sqrt{(1+\frac{R_W^2}{X_W^2}){S_W}^2-Q_X^2}}{1+\frac{R_W^2}{X_W^2}}$

$s.t.0<Q_X\&le;\frac{R_W}{X_W}{S}_W---\left(2\right)$

When power station does not configures reactor, i.e. Q_X=0, formula (2) can turn to:

$\mathrm{\&Delta;}P=(1-\frac{1}{\sqrt{1+R_W/X_W}})S_W---\left(3\right)$

Object function minC_X(Q_X) be made up of four parts, be respectively as follows: unit enter phase pressure regulation cost, reactor mounting cost, Reactor arrangement expense and reactor maintenance cost, arranging available object function is:

$\begin{array}{c}\min C_X\left(Q_X\right)=24C_W{T}_X{T}_W(S_W-\frac{\frac{R_W}{X_W}{Q}_X+\sqrt{(1+\frac{R_W^2}{X_W^2}){S_W}^2-Q_X^2}}{1+\frac{R_W^2}{X_W^2}})+C_{X1}+C_{X2}{T}_X+C_{X3}{Q}_X\\ \left(0<Q_X\&le;\frac{R_W}{X_W}{S}_W\right)\end{array}---\left(4\right)$

Step S150: judge that unit enters whether phase pressure regulation cost is more than or equal to the size of the target function value after optimizing.

Step S160: the most then export the information of the reactor that installed capacity is capacity optimal solution.

Specifically, when unit enters the size that phase pressure regulation cost is less than the target function value after optimizing, electricity is not installed in output The information of anti-device.
