【摘要】 随着现代电力系统的发展,对电力系统自动化和安全基础设施提出了更高的要求。在这个背景下,电力系统的监测和控制均向广域测量方向发展。为此,提出了电力系统传感器网络的新方案来为电力系统安全监控提供服务。测量的时间同步精度问题是该广域测量系统的最关键的因素之一。本文对电力系统传感器网络中的IEEE1588高精度时间同步协议在OPNETTM仿真软件中进行建模并仿真,验证了IEEE1588在电力系统广域时间同步测量中的有效性。更多还原

【Abstract】 The development of power system raises higher requirements for power system automation system and security infrastructure.Both the power system monitoring and control are developing toward wide-area measurement.power system sensor network (PSSN) is proposed as a solution for power system security monitoring and control.The precision of time synchronization is one of the most critical factors in wide-area measurement.This paper attempts to model and simulate the IEEE 1588 time synchronization protocol used in PSSN,to testify the effectiveness of the scheme.更多还原
