摘要
为了实现电力系统通信数据网传输信道均衡设计,提高数据网的传输性能,需要进行信道优化自动测试设计,提出一种基于分簇链路稀疏性配置的电力系统通信数据网传输信道自动测试平台设计方法。利用S-V(Saleh-Valenzuela)统计模型构建电力系统通信数据网传输信道模型,计算数据网传输链路的冲激响应,对电力系统通信数据网传输电力数据进行最大似然估计,使得电力系统通信数据网传输信息特征分量以簇的形式在接收终端得到有效检测,根据分簇链路均衡控制模型进行网络传输信道自动测试优化设计。测试结果表明,采用该方法进行电力系统通信数据网传输特性测试的抗干扰性较好,测试结果准确可靠,电力系统通信数据网传输的误码率较低。
In order to realize the transmission channel equalization design of power system communication data network and improve the transmission performance of the data network,it is necessary to carry out the channel optimization automatic test design.A design method of automatic test platform for transmission channel of power system communication data network based on cluster link sparsity configuration is proposed.The S-V(Saleh-Valenzuela)statistical model is used to construct the transmission channel model of the power system communication data network.The impulse response of the transmission link of the data network is calculated,and the maximum likelihood estimation of the transmission power data of the power system communication data network is carried out.The characteristic components of transmission information in power system communication data network are effectively detected in the receiving terminal in the form of clusters,and the network transmission channel automatic test optimization design is carried out according to the cluster link equalization control model.The test results show that the method has good anti-interference,accurate and reliable test results,and low bit error rate(BER)of power system communication data network transmission.
