摘　　要：由于传统方法在风电并网发电通信中的应用效果不佳,提出数字微波通信技术在风电并网发电通信中的应用。结合风电并网发电通信的需求,确定通信天线数量、信号发射端与接收端的距离以及传输视距,完成风电并网发电的通信物理配置。利用微波通信技术对风电并网发电通信的信道进行编码、频道扩展处理,采用二进制相移键控方法对基带信号进行载波调制,在信号接收端通过对通信信号解码处理实现对发电信号传输,进而实现基于数字微波通信技术的风电并网发电通信。经实验证明,设计方法的信号传输时间在1 s以内,数据丢失量占总量的比例较小,数字微波通信技术在风电并网发电通信中具有良好的应用前景。Because the application effect of traditional methods in wind power grid-connected power generation communication is not good,the application of digital microwave communication technology in wind power gridconnected power generation communication is proposed.Combined with the requirements of wind power gridconnected power generation communication,the number of communication antennas,the distance between signal transmitter and receiver and the transmission sight distance are determined to complete the communication physical configuration of wind power grid-connected power generation.The microwave communication technology is used to encode and expand the channel of wind power grid-connected power generation communication,and the binary phase shift keying method is used to carry out carrier modulation on the baseband signal.At the signal receiving end,the power generation signal is transmitted by decoding the communication signal,and then the wind power grid-connected power generation communication based on digital microwave communication technology is realized.Experiments show that the signal transmission time of the design method is less than 1 s,and the proportion of data loss is small.Digital microwave communication technology has a good application prospect in wind power grid-connected power generation communication.
