Practical Identification Method of Frequency Regulation Controller for Full-power Wind Turbines
摘要
Abstract
Establishing a wind turbine model that is consistent with the actual frequency response characteristics is the prerequisite and foundation for analyzing the frequency safety and stability of power systems with high proportion of renewable energy.At present,there is little research on frequency simulation modeling of wind turbines,and intelligent algorithms are mostly used to identify control parameters based on the known structure of frequency regulation controllers,lacking universality and engineering practicality.First,a universal electromagnetic transient model that can cover mainstream models of full-power wind turbines in China is established.On this basis,aiming at the feasible frequency regulation control strategy for wind turbines,a comprehensive frequency regulation control system covering all elements is constructed including overspeed de-load control,pitch angle control,virtual inertia control,and droop control.Then,based on the correspondence between the frequency response characteristics of the unit and the frequency control strategy/parameters,a practical identification method is proposed,which adopts the morphology of the measured frequency response characteristic curves of the unit to identify the structure of the frequency regulation controller,and uses the eigenvalues of the measured frequency response characteristic curves of the unit to identify the parameters for the frequency regulation controller.Finally,the effectiveness of the proposed identification method for the frequency regulation controller is demonstrated by comparing the electromagnetic transient model of the unit established by the proposed practical identification method for the frequency regulation controller with the"black box"model of manufacturers and the frequency regulation response characteristics of on-site tests.关键词
