Abstract
The utility model relates to a controllable reactive and harmonic generator circuit comprising a DC circuit 1, an inverted circuit 2, and also a three-phase adjustable load circuit 3 that is connected with the inverted circuit 2 by three-phase AC contactors (QZB and QXB); an adjustable resistance R9, a resistance R10, and a resistance R11 are connected in series between the three-phase adjustable load circuit 3 and a grounding pole O. The reactive current and harmonic current emitted by the utility model can change along the current of the adjustable load per rata, so that manual control of the reactive and harmonic generator can be realized by manually adjusting the resistance value of the adjustable resistance.
Description
Technical field
The utility model belongs to the electric power project engineering field, particularly relates to the idle and improved design of harmonic oscillator circuit of a kind of controllable type.
Background technology
The harmonic wave and the idle variation of the automatic follow load of existing idle and humorous wave generating device, thereby artificial controllability is relatively poor when debugging and experiment.Can't obtain the idle and harmonic current that the commissioning staff needs, and the electrorheological law.
Debug and test required big electric current, the humorous low-power factorial experiments environment that involves at distribution static reactive power compensation arrangement (D-STATCOM), the domestic test corollary equipment accordingly that also lacks.Through improvement, become the experimental enviroment simulator of D-STATCOM reactive-load compensator device to test to reactive power compensator D-STATCOM.
Summary of the invention
The purpose of this utility model provides the idle and harmonic oscillator circuit of a kind of controllable type, to overcome the required big electric current of experiment, the humorous low-power factorial experiments environment shortage that involves, the domestic shortcoming that also lacks corresponding test corollary equipment.
In order to realize that above-mentioned purpose the technical solution of the utility model is: a kind of controllable type is idle and the harmonic oscillator circuit comprises DC circuit 1, inverter circuit 2 is characterized in that: also be provided with the three-phase tunable load circuit 3 that joins by three-phase ac contactor QZB, QXB and inverter circuit 2; Described three-phase tunable load circuit 3 be and earth electrode O between be connected with adjustable resistance R9, resistance R 10, resistance R 11 respectively.
Adopt the utility model of above-mentioned measure, the electric current of reactive current that it is idle and harmonic oscillator sends and harmonic wave current following tunable load changes the ratio that forms and changes.Thereby the resistance by the manual adjustment adjustable resistance has realized the Artificial Control to idle and harmonic oscillator.
