2MW doubly fed induction wind turbines in the North re-company success
The first gas turbine by Beijing North re limited liability company (hereinafter referred to as the "North Heavy Company") made BZD80-2000 (low temperature) wind turbine in China Datang Group Tongliao Huolinhe Wind (50MW) success and power generation . Used in these units in our self-developed 2MW VSCF doubly fed induction wind turbines, the project has filled the domestic wind power equipment manufacturing, a blank indicates that the North has become a 2MW re-VSCF doubly-fed induction wind turbine technology independent intellectual property rights of enterprises, and become a megawatt-class wind turbine manufacturing competitiveness of enterprises!
North heavy company to seize the building of wind power generator in China to actively promote this rare opportunity, and actively committed to wind power equipment at home, with fifty years experience in the development of large generators, and wind turbines manufacturing advantages, the successful production of 2MW wind power doubly fed induction machine. The motor in strict accordance with IEC60034 standard and North re-introduction of the 2MW wind power company sets the requirements for design technology, applied in cold, high altitudes and hot and humid, salt spray in coastal areas to run, the main technical specifications: Rated voltage 690V; rated current 1670A; frequency 50Hz; rotor rated voltage 1840V; rotor rated current 670A;, Poles 4 Pole; rated speed 1660rpm; power speed range of 520-1950rmp; Insulation Class H; protection class IP54; center height H = 500mm; motor temperature rise ¦¤t <95K. . 2MW doubly fed induction wind turbine design special, product reliability, and security is high, so research of experiments, the original data acquisition methods, test data, the analysis of Yi Ji Zhi Liang of the assessment to the grid Deng Fangmian to IEC60034 series of strict international standards criterion, after many experiments, improved electrical parameters and structure, to achieve the optimum design objectives.
2MW VSCF doubly fed induction wind turbines in the North re-developed the company independently, will be our field of wind power equipment manufacturers play a full role in promoting localization.
