Problems solved by technology

This puts forward higher requirements on the insulation level of the winding, which increases the cost and correspondingly increases the volume of the reactor.
Harmonics generated by nonlinear characteristics and higher requirements on insulation level are the obvious shortcomings of this type of contact controllable reactor.

Embodiment Construction

[0039] Since both the magnetic valve type controllable reactor and the split core type controllable reactor have the defects of obvious nonlinear characteristics, relatively large harmonics and high requirements for insulation, the purpose of the present invention is to use the magnetic domain theory and Based on the analysis of the material characteristics of grain-oriented silicon steel, a new type of non-contact controllable reactor structure is obtained. Three different types of control windings are used to reduce the harmonics of the reactor, reduce insulation requirements, and simplify the manufacturing process.

[0040] The operating points of the traditional magnetic valve type and split core type controllable reactors are all selected in the nonlinear region near the saturation section, such as Figure 5 As shown, the reactor works in this region to ensure that a larger inductance change can be obtained through a smaller DC bias. But this non-linear region also makes ...

Abstract

The invention belongs to power device technique field, as non-contact controllable reactor, which separates the dc control winding and ac operating winding in space, uses the adjustable hollow solenoid, the hollow solenoid with variable dc excitation, and the semi-iron core / circular-iron core straight solenoid with dc excitation as control winding. Wherein, regulating the reactance value by changing magnetic flux, controlling the magnetic saturation degree of semi-iron core, and controlling the rotation direction of magnetic domain of circular-iron core in cross magnetic field, improving the nonlinear character of traditional product, reducing harmonic wave quantity and reactor volume. This invention has wide application in power system.

Description

technical field [0001] Non-contact controllable reactors can be used in reactive power compensation of power systems, high-order harmonic filters, limiting power frequency overvoltage, suppressing voltage flicker, maintaining reactive power flow balance, etc. Background technique [0002] Controllable reactors have very broad application prospects and great potential in power systems. Below are the ranges and functions it can be applied to. [0003] (1) Used as phase modulation and voltage regulation equipment in ultra-high voltage power grid [0004] Because the controllable reactor can be made into any voltage level and directly connected to the ultra-high voltage power grid, it has significant technical advantages and economical efficiency. In the hub station and large terminal station of the ultra-high voltage power grid, in order to compensate the reactive power required by the area to adjust the voltage and maintain the stability of the system, and for the constructi...
