摘要(Abstract):

NTP(网络时间协议)在电力系统中应用广泛,具有应用成本低廉等优点,但对时精度一直相对较低。为进一步提高变电站监控系统NTP对时精度,在研究计算机时钟模型和时钟误差因素的基础上,对时间同步过程中的各个影响环节进行逐项分析,给出了时间采样流程,并对时间采样样本进行回归分析,计算出相差和频差,进而调用内核时间调整功能,实现了NTP对时精度的提高。
The NTP(network time protocol) has been widely used in power system, the cost of which is low but the timing accuracy is not ideal. In order to improve the timing accuracy of the substation monitoring system and on the basis of combing the computer clock model and the clock error factor, the various influencing factors in the time synchronization process are analyzed item by item, and the time sampling process is given and subjected to regression analysis to calculate the phase difference and frequency difference, and then the kernel time adjustment function is adopted to improve NTP timing precision.
