摘　　要：针对风电场参与紧急功率速增控制的情景,以直驱式风力发电机组(direct drive wind power system,DDWPS)为研究对象,对其超速减功率运行进行了研究。搭建了基于Simulink的DDWPS,对不同风速条件下的机组超速减功率与发电机转子动能存储性能进行了仿真。由于转子储能可以有效提高紧急功率速增的支撑,因此以最大转子动能储备为优化目标,利用GUROBI优化软件对某风电场多台DDWPS的超速减载率进行优化。结果表明,额定风速条件下的风机与低于额定风速条件下的风机相比,其减载率应较小,以增加整个风电场多台机组的转子总动能。方法的实现可为风电场参与紧急功率速增控制提供理论与工程基础。Aiming at the scenario of wind farm participating in emergency power rapid increase control,the direct drive wind power system(DDWPS)was used as the research object,and its overspeed power reduction operation was studied.A Simulink-based DDWPS was built to simulate the overspeed reduction power of the unit and the kinetic energy storage performance of the generator rotor under different wind speed conditions.Because the rotor energy storage can effectively improve the support of emergency power rapid increase,the maximum rotor kinetic energy reserve was taken as the optimization goal,and the GUROBI optimization software was adopted to optimize the overspeed load shedding rate of multiple DDWPS in a wind farm.The results show that the load shedding rate of the wind turbine at the rated wind speed should be less than that one below the rated wind speed,so as to increase the total kinetic energy of the rotors of multiple units in the entire wind farm.The realization of the method can provide a theoretical and engineering basis for wind farms to participate in emergency power rapid increase control.
