Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment:
Wind farm grid-connected some reactive power/voltage control, namely each wind farm grid-connected reactive-load compensation equipment installed that utilizes carries out reactive power/voltage control.According to national regulation, each wind farm grid-connected point should be equipped with all kinds of reactive-load compensation equipment, and as shunt capacitor, reactor, SVC, SVG etc., and wind energy turbine set booster stations transformer should be a year adjustment transformer.
Meritorious the exerting oneself of wind energy turbine set has very strong fluctuation and unsteadiness, and the meritorious fluctuating range of exerting oneself of wind energy turbine set has a significant impact wind farm grid-connected point voltage characteristic.When wind energy turbine set is gained merit and exerted oneself vary within wide limits, wind farm grid-connected point voltage fluctuating range is also comparatively large, and the meritorious amplitude of variation hour of exerting oneself of wind energy turbine set, wind farm grid-connected point voltage fluctuating range is also less.Wind power output may significantly rise fast in the short period of time or decline, and is reflected on the voltage of wind farm grid-connected point, be exactly voltage significantly changes with significantly changing fast of output of wind electric field.
When wind power output fluctuating range is larger, in order to control voltage is stablized, need to drop into jumbo reactive power compensator.Low-voltage capacitance, that reactor has capacity is large, cost is low, grouping switching is compensation characteristic flexibly, but low-voltage capacitance, reactor are generally all by circuit breaker connecting system, can only grouping switching, and the operating time is long, idle regulating continuously fast can not be realized, the reactive power compensation of step evolution can only be carried out system, be therefore suitable as the basic component of reactive power compensation, for wind-powered electricity generation exert oneself greatly changes in amplitude fluctuation time reactive voltage coarse adjustment.
When wind power output fluctuating range is less, need less Reactive-power control amount can meet Reactive-power control requirement, and wind power output pace of change is fast by a small margin, fluctuation is frequent, needs to select continuity reactive-load adjusting device fast to carry out reactive power/voltage control.SVG adopts igbt (IGBT), gate pole can the device that can turn off rapidly such as Guan Jingguan (GTO), rapid succession can be realized and regulate reactive power, what the response time was the fastest can accomplish 20ms--100ms, can be used in stabilizing the wind-powered electricity generation wind farm group that causes of rapid fluctuations the voltage fluctuation of site by a small margin, improve system power quality.But SVG is general, and capacity is less, and unit capacity cost is higher, is therefore suitable as trim component, is used for the voltage fluctuation that Rapid Variable Design by a small margin that regulating wind power exerts oneself causes, and capacity reactance device carries out the voltage trim after coarse adjustment to significantly voltage fluctuation.The characteristic that SVG responds fast, makes it have when to suffer the large disturbances such as short trouble in system, provides reactive voltage fast to support, improve the voltage stability of system.Under the abundant condition of System Reactive Power, the on-load tap-changing transformer (OLTC) of wind energy turbine set booster stations can change the reactive power distribution of system by adjustment tap, to transformer medium voltage side and low voltage regulation, and it is very limited to the pressure regulation effect of high-voltage side bus, and each continuous action gear of the tap gear of OLTC can not more than 3 grades, the total gear of action every day can not more than 4 grades, and therefore, OLTC can only as the auxiliary pressure regulation means of reactive-load compensation equipment adjustment.

2) according to the real-time voltage U of the wind farm grid-connected point of Real-time Obtaining, exerting oneself of wind energy turbine set is predicted;
3) exert oneself according to real-time voltage U and wind energy turbine set prediction, adopt the mode of throwing/moving back electric capacity tentatively to control wind farm grid-connected some reactive voltage, adopt SVG accurately to control simultaneously, as shown in Figure 2, specifically comprise the following steps:
31) judge whether real-time voltage U is in 1.0U
n~ 1.06U
nscope in, if so, then carry out step 32), as no, then carry out step 33);
32) adopt the reactive voltage of SVG to wind farm grid-connected point to regulate, make real-time voltage U approach control definite value 1.04U
n;
33) judge whether real-time voltage U is more than or equal to 1.06U
n, if so, then carry out step 34), if not, then carry out 35);
34) continue to reduce along with wind energy turbine set prediction is exerted oneself, grouping is exited capacitor and is dropped into reactor successively, and adopts on-load tap-changing transformer to carry out pressure regulation as regulator for subsequent use, makes real-time voltage U approach control definite value 1.04U
