摘　　要：随着能源向绿色低碳方向转型发展,风电作为清洁能源的重要组成部分,在能源结构体系中占比呈现出快速增长趋势,电力系统中因同步发电机组的减少使得系统惯性降低,为了确保电网系统的稳定,提出新能源场站需具备一次调频功能。实现传统存量风力发电机组在不额外增加储能装置的情况下满足新国标中对一次调频功能的技术要求。基于风力发电机组的有功率控制逻辑,提出关键参数的自适应及动态调整控制技术。形成了快速调频状态下有功功率关键控制参数动态调整方法,解决了有功功率控制稳定性和响应及时性难题,提升了有功功率实际值与目标值的匹配程度。解决了传统存量风电机组有功功率提升时桨距角调整的滞后性与电能快速转换需求间的矛盾,满足了新国家标准中对于一次调频功能的技术指标并提高了风能利用效率。研究成果可为传统存量风电机组响应一次调频技术要求提供一定参考。With the transformation and development of energy towards green and low-carbon direction,wind power,as an important component of clean energy,has shown a rapid growth trend in its proportion in the energy structure system.The reduction of synchronous generator sets in the power system has led to a decrease in system inertia.In order to ensure the stability of the power grid system,it is proposed that new energy stations should have a primary frequency regulation function.To meet the technical requirements for primary frequency regulation in the new national standard without adding additional energy storage devices for traditional existing wind turbines.Based on the power control logic of wind turbines,adaptive and dynamic adjustment control techniques for key parameters are proposed.A dynamic adjustment method for key control parameters of active power under fast frequency regulation has been developed,which solves the problems of stability and timely response of active power control,and improves the matching degree between actual and target values of active power.The contradiction between the lag in pitch angle adjustment during the active power increase of traditional existing wind turbines and the demand for rapid energy conversion has been resolved,meeting the technical indicators for primary frequency regulation function in the new national standard and increasing wind energy utilization efficiency.The research results can provide some reference for the response of traditional existing wind turbines to the requirements of primary frequency regulation technology.
