With the continuous development of science and technology, leading companies actively explore new technical fields, especially in the field of offshore oil drilling and oil production control, saving a lot of foreign exchange for the country; Under the guidance of power electronics experts from Tsinghua University and Huazhong University of Science and Technology, standardized designs have been made for MVD series high voltage variable frequency governor (MVD), XDSSVG series active dynamic reactive power and harmonic compensation device (SSVG), AFP low voltage filter device, full digital excitation device of synchronous motor, magnetic control soft start device (SSQ), hydraulic resistance soft start device, silicon controlled soft start device, etc., so that the standard products tend to be perfect and convenient for users to choose and apply. These products have been running stably in hundreds of factories and substations at home and abroad.
