针对风力机结冰问题,提出了一种采用外置设备进行结冰探测的方法,该方法的基本思路是将传感器集成在独立于风力机之外的结冰探测器上,通过对该外置结冰探测器的结冰进行探测,获知风力机的结冰；给出了外置式结冰探测器设计的基本方法和步骤,建立了设计结冰探测器外形所需要的数值算法,包括空气流场计算的MRF方法、水滴运动轨迹计算的拉格朗日法、结冰的快速计算方法；采用本文方法对某1.5MW级水平轴风力机进行了结冰探测器设计,得到的探测器可以实时反映风力机叶片结冰的情况,说明本文提出的设计思路及方法是行之有效的,以上工作为进一步发展风力机结冰防护技术打下了良好基础.%A method of designing icing detection system for wind turbine is presented in this paper. The main idea of the approach is to integrate icing sensors on an extra prober and to predict ice on wind turbine according to the prober icing. Basic steps for design are proposed. Numerical arithmetic used for design configuration and shape of the icing prober is given. The arithmetic is composed of the Multiple Reference Frame (MRF) method to calculate flowfield of air, a Lagrangian method to compute droplet trajectories and a technique for fast computing ice accretion. Icing prober configuration for a 1. 5MW horizontal axis wind turbine is then obtained with the approach. The state of wind turbine icing can be indicated by the prober in real time. All these achievements build a good base for future research.
