Abstract

The rotating electromagnet active power and the reactive power progressing adjusting device belongs to the electric machine domain, it solves the problem of the high setting cost, the low reliability, the bad anti-jamming ability and the depression of the stability of the electric net used for compensating the active power and the reactive power of the electric net in being. The invention adopts the first coiling rotor respondent electric engine (1) and the second coiling rotor respondent electric engine (2), the two electric engine have the same frame, the phase orders of the stator coiling group of the coiling rotor respondent electric engine are reverse, they are connected to the transmission line of the electric power net, the rotor coiling group (1-2) of the first coiling rotor respondent electric engine (1) is connected with the stator coiling group (1-1) through the impedance unit (3) and the switching on-off unit (7), the two coiling rotor respondent electric engine connects with the same axes, then, it connects the moment fan-out of the rotor driving setting (4). The invention has many merits such as the low cost, the high reliability, high ability of over loading, the adopting of the active power and the reactive power, the high ability of anti-jamming and the avoidance of affection of the stability of the electric net.

Description

technical field [0001] The invention relates to a rotating electromagnetic active and reactive power continuous adjustment device, which belongs to the field of motors. Background technique [0002] The application of power electronic devices is becoming more and more widespread. The power factor of many power electronic devices is very low, which brings additional burden to the power grid and affects the quality of power supply. Therefore, improving the power factor has become a major issue in power electronics technology. Typical devices used to compensate reactive power mainly include synchronous condensers and static var compensators SVC. The synchronous condenser can be regarded as a synchronous motor in no-load state, and the reactive power absorbed by the synchronous condenser can be adjusted by adjusting the magnitude of the excitation current. When the synchronous condenser is over-excited, it can absorb the leading reactive current from the grid; when it is under-...
