Description

The magnet controlled voltage regulating imaginary power automatic compensation device
Technical field
The utility model belongs to the circuit arrangement of transformer station, ac mains or ac distribution network, particularly uses the circuit arrangement of the ac distribution network of adjusting reactive power.
Background technology
Reactive power compensation is exactly that device and inductive load with capacitive power are connected in same circuit, when capacitive device releases energy, inductive load absorbs energy, and inductive load is when releasing energy, capacitive device absorbs energy, energy is in mutual conversion, and the reactive power that inductive load absorbed can be compensated in the reactive power by capacitive device output.The mode of reactive power compensation has synchronous compensator SC, shunt capacitor MSC (FC), Static Type Dynamic Reactive Compensation Device SVC, static reacance generator SVG (STATCOM), also has the voltage-regulation type reactive power compensator.The shunt capacitor compensation is present most popular a kind of reactive power source, but having capacitance group is grouping switching, the switching big shortcoming of shoving, the voltage regulating imaginary power compensation realizes by on-load voltage regulating switch, have 9 gears, be equivalent to capacitor branch with a constant volume for 9 groups, do not have real realization smooth adjustment.Static Type Dynamic Reactive Compensation Device and the high investment of static reacance generator price are big.
The utility model content
In order to overcome the grouping switching that existing reactive power compensator has, the adjusting that switching shoves greatly, has not steadily, the high deficiency of cost that has, the purpose of this utility model provides a kind of magnet controlled voltage regulating imaginary power automatic compensation device, this magnet controlled voltage regulating imaginary power automatic compensation device not only can not produce because of grouping switching produces and shove, realizes level and smooth conciliation, and cheap.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of magnet controlled voltage regulating imaginary power automatic compensation device, it is characterized in that: by the control coil that is connecting the adjustable low-voltage DC power supply that is looped around on the iron core, actuating coil is formed with the autotransformer that is being connected actuating coil and capacitor.
For uniline, described iron core is the control coil of its two column jacket of four column iron cores around the mutual polyphone that links to each other with the adjustable low-voltage DC power supply, on two column jackets also around actuating coil parallel with one another, this actuating coil one end is connecting autotransformer and the capacitor that is wrapped on two inner props successively, and to be the actuating coil interface end link to each other with the electrical network that needs carry out reactive power compensation respectively with the capacitor interface end other end.
For three-phase line, described iron core is that three group of four column iron core is looped around control coil on each iron core two column jacket and connects mutually and link to each other with the adjustable low-voltage DC power supply, on each iron core two column jacket also around actuating coil parallel with one another, this actuating coil one end is connecting autotransformer and the capacitor that is wrapped on two inner props successively, the capacitor that links to each other with each iron core autotransformer links to each other with each phase line of electrical network respectively, and the other end actuating coil interface end of actuating coil is interconnected to asterism on each iron core.
The main feature of the disclosed magnet controlled voltage regulating imaginary power automatic compensation device of the utility model is the idle amount by computer detecting system, reach the adjustment exciting current by the direct voltage of regulating the control coil two ends, realize adjusting the excitation of magnetic control autotransformer, thereby the output end voltage that changes voltage regulator reaches the voltage of adjusting the capacitor two ends, thereby reaches the purpose of the reactive capability of adjusting capacitor.According to formula Q=2 π fCU 2Reactive power compensation is carried out in electric power system.This device changes the capacitor grouping switching for one-time fixing input, changes the idle output of capacitor by the voltage of adjusting the capacitor two ends, technical problem such as solved the overvoltage in the capacitor switching, shove; By the voltage at control magnetic controlled voltage regulator excitation adjustment capacitor two ends, becoming has grade pressure regulation to be the magnetic control stepless voltage regulation, has really reached idle the carrying out of system smoothly regulated automatically, and reaction speed is fast, the compensation precision height.
To be these reactive power automatic compensation devices change the idle output of capacitor by the voltage of adjusting the capacitor two ends to the beneficial effects of the utility model, technical problem such as solved the overvoltage in the capacitor switching, shove; The realization stepless voltage regulation has reached smoothly to be regulated automatically to idle the carrying out of system, and reaction speed is fast, the purpose that compensation precision is high, it is simple in structure, and is reliable, and cost is low, can reduce line loss significantly, improve the economic benefit of power supply enterprise, be adapted at urban and rural power grids and large and medium-sized enterprise and be extensive use of.
