Embodiment

[0035] A typical single-phase saturated reactor such as figure 1 shown. Including terminal I1, terminal II2, terminal III5, terminal IV6, saturated reactor closed-loop core 3, control circuit 4. The closed-loop iron core 3 of the saturable reactor has at least two iron core columns with equal cross-sectional areas and coils; each of the two iron core columns can at least form a magnetic flux closed loop that does not pass through the opposite iron core column.

[0036] The closed-loop iron core 3 may be two closed-loop iron cores that have no passages to each other, for example 1: two square-shaped iron cores. It can also be an integrated closed-loop iron core with mutual passages; for example 2: three iron core columns, and there are yokes at both ends of the iron core columns to connect the three iron core columns. Any two iron core columns can form a magnetic flux closed loop with each other. But there are at least two of them that can respectively form closed loops that ...

Abstract

The invention relates to a three-phase saturation resistor capable of reducing bounded uncertainty, which comprises an A-phase saturation resistor, a B-phase saturation resistor and a C-phase saturation resistor, wherein terminals A1, B1 and C1 of the A-phase, B-phase and C-phase saturation resistors are respectively connected A-phase, B-phase and C-phase voltages of a power system; terminals A5, B5 and C5 of the A-phase, B-phase and C-phase saturation resistors are connected together and are connected to a terminal N through a resistor R1; and terminals A6, B6 and C6 of the A-phase, B-phase and C-phase saturation resistors are connected together and are connected to the terminal N through a resistor R2. According to the invention, the bounded uncertainty of the three-phase saturation resistor can be reduced; and no matter how the change of the working current of the three-phase saturation resistor, the power frequency current in a neutral line of the three-phase saturation resistor is always zero, and the resistors can not consume the energy of the power frequency current.

Description

technical field [0001] The invention relates to the technical field of power transmission and transformation in power systems, in particular to a three-phase saturated reactor for reducing bounded uncertainty. Background technique [0002] Reactors are widely used in power systems. The series reactor can limit the short-circuit current; the shunt reactor can limit the overvoltage; the combination of the reactor and the capacitor can form a filter circuit. In some application fields, the reactance value of the reactor is fixed; in some application fields, the reactance value of the reactor should be adjusted continuously with the change of the power system operation mode. The controllable saturable reactor (also called: saturable reactor, magnetron reactor) whose reactance value can be adjusted continuously is an important research topic. [0003] The saturable reactor uses the saturation characteristics of the closed-loop iron core of the saturable reactor to change the re...
