Abstract

The invention discloses a mechanical transient and electrical transient mixed simulation system and method of wind turbine generator system. The mechanical transient and electrical transient mixed simulation method comprises the steps of conducting simulation calculation to the mechanical transient process of the wind turbine generator system and acquiring the result and the step interval of the simulation calculation; at the same time when the simulation calculation is conducted to the mechanical transient process, conducting simulation calculation to the electric transient process of the wind turbine generator system and acquiring the result and the step interval of the simulation calculation; and then conducting real-time data exchange to the simulation calculation result of the mechanical transient process and the simulation calculation result of the electrical transient process, and enabling the two simulation calculation steps to be synchronized by unifying the step intervals till completion time set for the two simulation calculation steps is reached. Therefore, the respective advantages of mechanical transient simulation and electric transient simulation are combined; and on the premise that the simulation accuracy of the wind turbine generator system is guaranteed, the simulation calculation speed is accelerated.

Description

technical field [0001] The invention relates to a simulation technology of a wind power generating set, in particular to a hybrid simulation system and method of a mechanical transient and an electrical transient of a wind generating set. Background technique [0002] The operating principle of the wind turbine is that the blades convert the wind energy in the air into the kinetic energy of the hub, and then transmit the kinetic energy to the generator through the gearbox and transmission chain, and finally the generator converts the kinetic energy into electrical energy, which is transmitted to the user through the grid. In the process of production and operation of wind turbine power generation, it usually includes two processes: one is the process of vibration, movement and deformation caused by mechanical components such as blades, towers, gearboxes, transmission chains, etc. , that is, the mechanical transient process. For example, when the wind wheel absorbs wind energ...
