Abstract

The invention discloses a unit cost annual energy output optimization method for a permanent magnet wind-driven generator. The method comprises the steps that (1) a total cost function and an annual energy output objective function of a generator system are established; (2) a unit cost energy output objective function system model is established; (3) optimization variables are selected; and (4) agenetic algorithm is adopted to optimize the unit cost annual energy output of the permanent magnet wind-driven generator. According to the method, in permanent magnet wind-driven generator design, aunited model comprising an electricity generation system, a wind energy capture system and a wind field operation prediction system of a wind turbine generator set is established with optimal unit cost annual energy output being a goal, and an artificial intelligence calculation method is adopted to perform optimal solving.

Description

technical field [0001] The invention belongs to the technical field of motor design, and in particular relates to a method for optimizing annual power generation per unit cost of a permanent magnet wind power generator. Background technique [0002] Since the beginning of the 21st century, with the rapid development of the global economy and society, the depletion of non-renewable energy such as coal and oil has become increasingly common, and the development of new energy has become a topic of global concern. Building a resource-saving and environment-friendly society is an urgent need In this context, new energy and high-performance generators are springing up like mushrooms. Among them, the technology of permanent magnet generators is becoming more and more mature. Compared with ordinary excitation generators, permanent magnet generators save The excitation winding, carbon brush, and slip ring structure of the excitation generator are removed, and the structure of the who...
