结合实际工程模型，对基于三网合一的过程层网络流量、延时、延时抖动等关键性能指标进行了研究分析，并根据分析结果研究分析了站内同步采样及站间同步采样原理及具体方案。最后对正常工况及主钟失步、合并单元失步等各种异常工况下采样方案的可行性进行了分析和验证，并对验证过程中出现的问题进行了分析，提出了改进方案。该方法对其他集中式保护研究及相关工程实践具有一定参考意义。

According to the model of practical project, the key performance indicators of process layer based on tri-networks integration, including the network traffic, the transmission delay and the jitter of the delay, are analyzed. Based on the analysis result, the synchronous sampling principles in a substation and between substations are analyzed and the specific sampling schemes are given. Finally, the feasibility of the sampling schemes in normal conditions and abnormal conditions such as the master clock or the merging unit out of step is analyzed theoretically and tested actually. By analyzing the problems which are exposed during the test, an improved sampling scheme is put forward. The study is referential to other research and engineering practice of centralized protection.
