摘　　要：对于智能变电站来说,其主要工作就是将达到一定标准的模拟量采样值及时、准确地传递给智能电子设备。但模拟量采样值在传输过程中,会受到各种因素的影响,从而导致其准确性和标准性存在偏差。因此,保证模拟量采样值的精准性,就需要建立一个采样值传输模型,并在建立模型的过程中,利用补偿传输延时方法进行,通过以太网对模拟量采样值的时效性进行监测,并根据常用计算公式进行理论分析,然后对采样值的准确性进行验证,尽可能降低误差。文章主要对智能变电站中采样值传输延时问题及处理措施进行详细分析和介绍。For the intelligent substation,its main work is to transfer the sampling value of analog quantity which has reached a certain standard to the intelligent electronic equipment in time and accurately.However,in the process of transmission,the sampling value of analog quantity will be affected by various factors,resulting in the deviation of its accuracy and standardization.Therefore,in order to ensure the accuracy of sampling value of analog quantity,it is necessary to establish a sampling value transmission model,and in the process of establishing the model,use the compensation transmission delay method,monitor the timeliness of sampling value of analog quantity through Ethernet,and make theoretical analysis according to the commonly used calculation formula,and then verify the accuracy of sampling value,so as to make the error as much as possible May be reduced.In this paper,the transmission delay of sampling value in intelligent substation and the processing measures are analyzed and introduced in detail.
