摘　　要：鼠笼异步风机因其成本低、可靠性高的特点在配电网中得到了广泛的应用,但其无序、无控的接入模式势必对电网带来灾难性的影响。基于PSCAD软件搭建了鼠笼异步风机的并网模型,建立了风速控制、异步电机转速负反馈以及风轮机桨距角追踪的有功功率输出控制策略。最后以实际的IEEE13节点配电网为仿真算例,研究该控制策略下的鼠笼风机并网以及风速波动时的有功功率输出状态,验证了控制策略的有效性。Squirrel cage induction fan has been widely used in distribution network because of its low cost and high reliability.However,its disordered and uncontrolled access mode is bound to bring catastrophic impact on the grid.Based on PSCAD software,the parallel network model of squirrel cage induction fan is built,and the active power output control strategies of wind speed control,speed negative feedback of induction motor and pitch angle tracking of wind turbine are established.Finally,taking the actual IEEE13-bus distribution network as a simulation example,the active power output state of squirrel-cage fan connected to the grid and wind speed fluctuation under the control strategy is studied,and the effectiveness of the control strategy is verified.
