Description
Technical field
The present invention relates to a kind of optimization method, relate in particular to the optimization method of a kind of VQC of transformer station (voltage and reactive power control) control mode.
Technical background
At present, comprise following several for the VQC of transformer station (voltage and reactive power control) control mode:
Mode one: main transformer on-load voltage regulation, capacitor Comprehensive Control;
Mode two: main transformer on-load voltage regulation is controlled automatically, and capacitor is stopped using;
Mode three: main transformer on-load voltage regulation is manually controlled, and capacitor is controlled automatically;
Mode four: main transformer has to carry automatically controls the capacitor timing controlled;
Mode five: main transformer on-load voltage regulation is manually controlled, the capacitor timing controlled.
At the second way of VQC (voltage and reactive power control), i.e. main transformer on-load voltage regulation is controlled automatically, and the control mode that capacitor is stopped using, the problem that takes place in transformer station's actual motion are gone into down:
See also Fig. 1, when system voltage was in 7 districts, two VQC sent the instruction of falling tap according to mode, but after overregulating, voltage directly strides across 9 districts and fallen 16 districts; VQC sends the instruction that rises tap when 16 districts, and after action, shake repeatedly thereby formed between 7 districts and 16 districts in voltage 7 districts that fall back again, the fluctuation that system voltage does not stop, at last when reach year action frequency 20 times day is arranged after, the VQC block action.
Summary of the invention
The objective of the invention is to overcome the defective of prior art, and provide a kind of optimization method of VQC control mode of transformer station, it can avoid the variation of voltage when regulating the main transformer gear than the transregional phenomenon that causes greatly, the adjusting repeatedly and the fluctuation that have solved the voltage that causes therefrom.
The technical scheme that realizes above-mentioned purpose is: a kind of optimization method of VQC control mode of transformer station, adopt main transformer on-load voltage regulation to control automatically, the control mode that capacitor is stopped using is controlled on-load transformer tap changer, this mode is controlled by 17 district's figure control strategies, described 17 district figure are voltage U by ordinate, abscissa is the coordinate that reactive power Q constitutes in first quartile, this zone is divided into 17, be respectively 1～17 district, wherein, 1 to 5 district is positioned at the upper area of coordinate, 6 to 12 districts are positioned at the central region of coordinate, 13 to 17 districts are positioned at the lower area of coordinate, wherein, when voltage U drops on central region, do not do any operation, promptly the system voltage reactive power satisfies service requirement.
The optimization method of above-mentioned VQC control mode of transformer station, wherein, all move by the mode of falling tap in 1 district to 5 district in described 17 districts, and all move by the mode that rises tap in the district in 13 districts to 17.
The optimization method of above-mentioned VQC control mode of transformer station, wherein, the central region of described coordinate is the zone that voltage U is constituted between 10.1KV to 10.6KV, and its top is described upper area, and the bottom is described lower area.
The invention has the beneficial effects as follows: the present invention is when implementing the control mode that main transformer on-load voltage regulation is controlled automatically, capacitor is stopped using, voltage regime is divided into three zones, upper, middle and lower, as long as voltage drops on zone line and just thinks qualified zone, no longer regulate, that just removes 7 districts and 11 districts respectively falls tap and rise the instruction of tap, thereby has solved transregional phenomenon and the adjusting repeatedly and the fluctuation of the voltage that causes therefrom.
