Abstract
The invention discloses an ultra-high-voltage-line parallel-connection controllable reactor which includes a controllable reactor, a controller, a rectifying tube, and a freewheel diode. One side of the controllable reactor is provided with the controller. A middle main iron core column of the controllable reactor is divided into two which are respectively wound with an upper winding and a lower winding, wherein the middle parts are in cross connection. The rectifying tube is arranged in the controllable reactor. Moreover, a center tap exists in each winding. Two symmetrically arranged DC assisting-magnetism thyristors are connected on each tap so that generated DC assisting magnetism is in self-closing in the two separated iron core columns without flowing out to side column iron cores. The reactor changes the triggering angle of the thyristor in the controllable reactor to control the saturability of the iron core so as to change the equivalent inductance so that the capacity of the reactor can be adjusted rapidly and continuously and thus an optimal effect of charging power compensation of an ultra-high-voltage power transmission line is realized and the device is low in price, simple to control and reliable in work and has a wide application and market prospect.
Description
Technical field
The invention belongs to ultra-high-tension power transmission line reactive power compensation technology field, relate to a kind of parallel controllable reactor of ultra-high-voltage line.
Background technology
At present, reactive balance is to improving the economic benefit of electrical network and to improve power supply quality most important, and the formation of superhigh pressure bulk power grid and load variations aggravation, require that the adjustable reactive power source of a large amount of response fast adjusts voltage, maintain System Reactive Power trend balance, Loss reducing, improve power supply reliability.
Summary of the invention
The present invention proposes a kind of parallel controllable reactor of ultra-high-voltage line, the saturation of iron core is controlled to change its equivalent inductance by the Trigger Angle changing thyristor in controlled reactor, realize the adjustment rapidly, continuously of reactor capacity, have cheap, control simple parallel controllable reactor of ultra-high-voltage line.
To achieve these goals, the technical solution adopted in the present invention is: a kind of parallel controllable reactor of ultra-high-voltage line, comprise controlled reactor, controller, rectifying tube, fly-wheel diode, the side of described controlled reactor is provided with controller, the middle main iron core post of described controlled reactor is divided into two, respectively around with upper and lower two windings, mid portion interconnection, the inside of controlled reactor is provided with rectifying tube.In addition, there is centre tap in winding, tap is connected to two direct current magnetism-assisting thyristors be arranged symmetrically with, and consequent direct current magnetism-assisting oneself in two split core posts is closed and do not flow out to side column iron core.Namely at the mid portion of four windings by self coupling transformation and controlled rectification, produce the direct current magnetism-assisting that direction is consistent, fly-wheel diode across on the intersection end points of reactor division stem stem winding and connection control instrument, afterflow task during finished goods brake tube shutoff.The middle part of the main iron core post of controlled reactor is provided with a small bore section and sidepiece contact resistance, to reach degree of depth saturation condition when magnetic flux is larger.The saturation of core of reactor can be regulated by the angle of flow and mozzle regulating thyristor, realize the object of smooth adjustment reactor equivalent inductance.
The invention has the advantages that: control the saturation of iron core to change its equivalent inductance by the Trigger Angle changing thyristor in controlled reactor, reactor self capacity can be regulated rapidly, continuously, realize the effect that best extra high voltage network charge power compensates, device has cheap, control simple, reliable operation, has wide application and market prospects.
