Problems solved by technology

Due to the intermittence, randomness and volatility of wind resources, the wind power output of large-scale wind power bases will fluctuate in a large range, which will further lead to fluctuations in the charging power of the transmission network and bring a series of problems to the safety of power grid operation.

Abstract

The invention discloses a wind turbine generator set dynamic model parameter testing method which comprises the following steps: a wind speed model is established to obtain simulated wind speed; a turbine and control system model is established, and mechanical power is obtained according to the obtained simulated wind speed; an electrical control model is established, and the electrical control model sends an active current control instruction and a wind turbine generator set electric potential control instruction to control a generator and a current converter according to the mechanical power, control point voltage and the terminal voltage of an output terminal of a generator and current converter module; the generator and the current converter generate active power and reactive power according to the active current control instruction and the wind turbine generator set electric potential control instruction respectively. The wind turbine generator set dynamic model parameter testing method has the advantage of providing an accurate calculation basis for power system stability analysis and power grid production scheduling.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to a method for testing parameters of a dynamic model of a wind turbine. Background technique [0002] At present, most of the large-scale wind power bases generated after my country's wind power enters the stage of large-scale development are located in the "three north regions" (Northwest, Northeast, and North China). Large-scale wind power bases are generally far away from the load center, and their power needs to be transmitted to load center for consumption. Due to the intermittence, randomness and volatility of wind resources, the wind power output of large-scale wind power bases will fluctuate in a large range, which will further lead to fluctuations in the charging power of the transmission network and bring a series of problems to the safety of power grid operation. Contents of the invention [0003] The object of the present invention is to propose a dynamic model pa...
