With the rapid development of modern power electronic technology and microelectronics technology, high-voltage and high-power frequency conversion speed-regulating devices continue to mature. High-voltage problems that have been difficult to solve have been solved in recent years through device serial connection or unit series connection.
Entrusted by the National Energy Administration, China Machinery Industry Federation and China National Petroleum Corporation hosted the Shanghai Guangdian Electric (Group) Co., Ltd. (hereinafter referred to as “the companyâ€) and China National Petroleum Corporation on November 1, 2013 in Shanghai. Gas-to-East Pipeline Co., Ltd. jointly developed a new product appraisal meeting for the "Series of large-capacity, high-voltage, variable-frequency inverters using oil-immersed transformers."
The company recently received the "Science and Technology Achievements Appraisal Certificate" issued by the China Federation of Machinery Industry (JK Kampo [2013] No. 1075), and the series of devices successfully passed the appraisal. According to the appraisal opinions contained in the appraisal certificate, the product developed is fully functional, has significant innovation, and can meet the application needs of the long-distance pipeline electric drive compressor set, and has reached the international advanced level in general. Among them, the speed sensorless control technology based on self-adaptive full-scale flux link observer directly detected by volt-seconds, the 6-phase motor stator flux-oriented vector control technology based on excitation current and torque current independent control have reached the international advanced level. The appraisal committee agreed to pass the appraisal.
The successful development of a series of large-capacity high-voltage variable-frequency speed regulating devices using oil-immersed transformers has enriched the product line of large-capacity high-voltage variable-frequency speed-regulating devices, improved product performance, and better fulfilled the diversification of equipment performance in long-distance pipelines. The demand has strengthened the competitiveness with foreign products and has broken the monopoly of foreign companies in the field of long-distance pipeline compressors. It is of great strategic importance to improve the level of domestic equipment manufacturing and ensure national energy security.
Large-capacity and high-voltage variable-frequency speed control devices can also be widely used in high-power wind tunnel test rigs of national defense technology, soft start of ultra-large blast furnace blowers in the metallurgical industry, compressor drives of large-scale oil refining and chemical conversion devices, and water pump variable speed drives in large-scale water transfer projects. And other fields. The new scientific and technological achievements of serialized large-capacity high-voltage variable-frequency speed-regulating devices using oil-immersed transformers have historic strategic significance in advancing the localization of equipment in these industries, lowering project investment, and ensuring national economic security.
The company will use this as an opportunity to further exert its technological and talent advantages in the research and development of power electronics products and enhance its core competitiveness.
