Abstract

The invention belongs to the field of an intelligent power device and a control device, in particular relates to a magnetic balanced harmonic elimination reactive compensation device and a method. According to the device and the method, three-phase unbalanced data of a circuit is acquired by a detector and is also stored and processed, the state of a load diverter switch on a load circuit is controlled so as to control access states of two branches connected with the detector, wherein one branch is provided with a magnetic balanced harmonic elimination device, the detector controls the load diverter switch to have access to the magnetic balanced harmonic elimination device according to power quality on a detection circuit of the detector when an exception occurs, and the original branch is cut off so as to perform magnetic balanced harmonic elimination. The method and the device have the following advantages that: 1, power supply quality is timely and accurately detected to reach economic operation, and operation loss of the original electromagnetic balanced power saver is effectively reduced; 2, switching in and switching out are convenient so as to guarantee power supply; 3, no-load loss can be effectively reduced; and 4, the device and the method are applicable for a place where a load condition is complicated and harmonic wave of a power grid is high, and power supply reliability is increased.

Description

technical field

[0001] The invention provides a magnetic balance harmonic elimination reactive power compensation device and method, belonging to the field of intelligent power equipment and control equipment. Background technique

[0002] Power system loads, especially living quarters, hospitals, schools, office buildings, and discontinuously operating factories and mines, undergo repeated peak-valley-peak changes every day, and a large amount of electricity is wasted during holidays.

[0003] Severe power grid pollution and unbalanced three-phase voltage power supply aggravate the loss of electric energy and make users suffer. The main reasons for the above problems are: grid pollution mainly based on harmonics, part of the high-order harmonics in the power supply is generated by the mains, and the other part is caused by low-voltage electrical and electronic equipment, such as the use of inverter power-saving technology, Effective power saving is only performed on a sing...
